Hypertension

Current efforts to control high blood pressure (BP) are failing in the United States and globally.

The first World Health Organization (WHO) global report on hypertension found that only 54% of adults with hypertension are diagnosed, 42% get treatment, and just 21% have their hypertension controlled.

In the United States, almost half (48%) of adults have high BP, defined as a systolic BP > 130 mm Hg, or a diastolic BP > 80 mm Hg, or are taking medication for high BP, according to the Centers for Disease Control and Prevention. Only about one in four adults (22.5%) with high BP have their BP under control.

High BP is a major risk factor for coronary heart disease, heart failure, and stroke, and the problem of controlling it is only getting worse. In 2024, the American Heart Association estimates that, “among adults, prevalence of hypertension will increase from 51.2% in 2020 to 61.0% in 2050.”
 

Pharmacists Most Effective

Though many factors contribute to hypertension, researchers have found that the kind of specialist leading the hypertension team may play a role in success. Currently, most BP control teams are led by physicians in primary care.

In a recent meta-analysis involving 100 randomized controlled trials and more than 90,000 patients in Circulation, Katherine T. Mills, PhD, School of Public Health, Tulane University, New Orleans, Louisiana, and colleagues found that, while all the groups studied who led BP control efforts were successful in reducing BP, pharmacist- and community health worker–led teams saw the biggest reductions.

Those groups’ efforts resulted in the greatest systolic BP drops: −7.3 mm Hg (pharmacists) and −7.1 mm Hg (community health workers). Groups led by nurses and physicians saw systolic changes of −3 and −2.4 mm Hg, respectively.

Similarly, pharmacist- and community health worker–led efforts saw the greatest diastolic BP reductions (−3.8 and −3.1 mm Hg), compared with nurse-led (−1.6) and physician-led (−1.2) efforts.
 

Reductions Enough to Cut Cardiovascular Disease Risk

The reduction numbers for pharmacists are clinically meaningful, Mills said in an interview. “It’s greater than a lot of what we see from individual lifestyle changes,” such as reducing sodium intake or increasing physical activity.

“It’s a big enough blood pressure change to have meaningful reduction in risk of cardiovascular disease,” she said.

This evidence that the leader of the team matters is particularly important because the treatment of hypertension is not in doubt. Something else is not working the way it should.

“We have basically all the scientific evidence we need in terms of what interventions work. But there’s a big gap between that and what’s actually being done in the real world,” she said.

Mills said she was not surprised that pharmacists got the best results “because so much of it has to do with titrating medications and finding the right kind of medications for each patient.”

Additionally, BP management and control falls right into pharmacists’ wheelhouse, Mills noted, including evaluating medication side effects and talking to patients about medication adherence.
 

Why Pharmacists May Be More Successful

In an accompanying editorial, Ross T. Tsuyuki, PharmD, with the EPICORE Centre, Division of Cardiology, University of Alberta in Edmonton, Canada, and coauthors said the Mills study provides further data to support pharmacists leading BP control efforts, but it’s not the data that have been keeping the model from changing. The barriers include turf wars and lack of legislative change.

The editorialists also said having pharmacist-led BP teams is only the first step. “We need pharmacists to independently prescribe,” they wrote.

“Since individual states govern the scope of practice of pharmacists,” the editorialists wrote, “we have the enormous task of changing regulations to allow pharmacists to independently prescribe for hypertension. But it can be done. The Canadian province of Alberta allows pharmacists to prescribe. And more recently, Idaho. While most states allow some sort of collaborative (dependent) prescribing, that is only a first step.”

Allowing pharmacists to independently prescribe will help populations who do not have a physician or can’t get access to a physician, the editorialists wrote. But changing state legislation would be a lengthy and complex effort.
 

Physician-Led BP Control Model ‘Seems to Fail Miserably’

Coauthor of the editorial, Florian Rader, MD, MSc, medical director of the Hypertension Center of Excellence at Cedars-Sinai Medical Center in Los Angeles, California, said in an interview that, currently, physician-led teams are the norm, “and that model seems to fail miserably.”

He offered several key reasons for that. In primary care, patients with hypertension often have other problems — they may have high cholesterol or diabetes. “They may have acute illnesses that bother them as well as hypertension that doesn’t bother them,” he said.

Physicians tend to find excuses not to increase or add BP medications, Rader said. “We tend then to blame ‘white coat effect’ or say ‘you’re just nervous today.’ ”

Pharmacists, comparatively, are more protocol driven, he said. “They essentially look at blood pressure and they have an algorithm in their mind. If the blood pressure hits the guideline-stated bar, start this medication. If it hits another bar, increase or add another medication.”

Rader said turf wars are also keeping physician-led teams from changing, fueled by fears that patients will seek care from pharmacists instead of physicians.

“I don’t think the pharmacists will steal a single patient,” Rader said. “If a physician had a healthcare partner like a pharmacist to optimize blood pressure, then [patients] come back to the physician with normalized BP on the right medications. I think it’s a total win-win. I think we just have to get over that.”

Pharmacist-led warfarin clinics are very well established, Rader said, “but for whatever reason, when it comes to blood pressure, physicians are a little bit more hesitant.”
 

Collaboration Yes, Independent No

Hypertension expert Donald J. DiPette, MD, Health Sciences Distinguished Professor in the Department of Internal Medicine at University of South Carolina, Columbia, said he completely agrees with Mills and colleagues’ conclusion. “Pharmacists and community health workers are most effective at leading BP intervention implementation and should be prioritized in future hypertension control efforts.”

The conclusion “is in line with the thinking of major organizations,” said DiPette, who helped develop the WHO’s most recent pharmacological treatment of hypertension guidelines. “WHO suggests that pharmacological treatment of hypertension can be provided by nonphysician professionals such as pharmacists and nurses as long as the following conditions are met: Proper training, prescribing authority, specific management protocols, and physician oversight.”

DiPette strongly believes BP control efforts should be supervised by a physician, but that could come in different ways. He suggested a collaborative but physician-supervised development of a protocol. Everyone contributes, but the physician signs off on it.

As for the Idaho example of independent practice for pharmacists, DiPette said he doesn’t think that will make a big difference in control rates. “That’s still not team-based care.”
 

Community Health Workers Key

He said he was also glad to see community healthcare workers emerge as the next-most-effective group after pharmacists to lead BP control teams. This is particularly important as BP control efforts globally need to consider the cultural experience of individual communities. “The community worker is on the ground, and can help overcome some of the cultural barriers,” he said.

“The key is to focus on team-based care and moving away from silo practice,” DiPette said.

Physicians, he said, often fall into “clinical or therapeutic inertia,” where BP is concerned. “We fail to titrate or add additional hypertensive medications even when they’re clearly indicated by the blood pressure. This is a problem not with the individual patient or the healthcare system, this is on us as physicians.”

Nonphysicians are more aligned with following protocols and guidelines, irrespective of the dynamics of what’s going on, he said.

And following protocols rigidly is a good thing for hypertension. “We’re not overtreating hypertension,” he emphasized. “We’re undertreating it.”

Reversing the trend on hypertension will take a sea change in medicine — changing institutions, systems, and individuals who have been doing things the same way for decades, he said.

“Our hypertension control rates are dismal,” DiPette said. “What’s more alarming is they’re going down. That’s the urgency. That’s the burning platform. We must strongly consider doing something different.”

Tsuyuki has received investigator-initiated arm’s length research grants from Merck, Pfizer, AstraZeneca, and Sanofi. He has been a speaker/consultant for Merck, Emergent BioSolutions, and Shoppers Drug Mart/Loblaw Companies Limited. Rader has been a consultant for Bristol Meyers Squibb, Cytokinetics, Idorsia, Medtronic, and ReCor Medical. Mills and coauthors reported no relevant financial relationships. DiPette declared no relevant financial relationships. He was part of a leadership team that developed WHO guidelines on hypertension.

Rachel S. Rubin, MD: I’m Dr. Rachel Rubin, a urologist and sexual medicine specialist in the Washington, DC, area. And I am so thrilled because my co-fellow, the brilliant and famous Dr. Ashley Winter, a board-certified urologist and a certified menopause practitioner, who sees patients in our practice from Los Angeles, is joining us today to talk about sex as a vital sign.

Ashley Winter, MD: To have the best sexual function, you need many different systems to work. You need your hormones to be in the right place. You need your blood vessels to dilate when you want them to. You need your nerves to connect to your genitalia to make them responsive. The way people say, “The eyes are the window into the soul” — well, the genitals are the window into the cardiovascular system, the peripheral nervous system, and the hormonal system. It’s so dynamic. Patients can understand how this reflects their health. We just need healthcare providers to hammer home how those things connect.

Rubin: If you’re a primary care doctor seeing a patient and you want to educate them on diabetes or high blood pressure, how can you “ ‘sell it with ‘sex”? How can you use sex to educate them about these important medical conditions?

Winter: I hate using it as a fear tactic, but sometimes you have to. Time and again, I’ve seen men with severe profound erectile dysfunction at a young age, with chronically uncontrolled diabetes.

Diabetes can impair the peripheral nerves, resulting in peripheral neuropathy. The same way that it can affect the fingers and toes, diabetes can affect the penis, even before those other areas. Diabetes can also lead to other conditions such as low testosterone, which also affects the function of the penis.

I’m being brutally honest when I tell patients that diabetes control is critical to having a wonderful sexspan — the duration of your life where you’re able to be sexually active and have great sex and do it in the way that you want.

Chronic conditions such as high cholesterol or hypertension can affect your ability to become erect or aroused whether you have a penis or a vulva, and even your ability to have an orgasm.

Rubin: None of my doctors has ever asked me about these issues. But we have to bring them up with patients because they›re not going to bring them up to us. I always say in the review of systems, we shouldn›t just ask, “Do you have any sexual problems?” (which nobody ever does) and move past the question about men, women or both. We should be asking, “Do you have any issues with libido? Do you want to talk about it? Any issues with erection, arousal, orgasm, or sexual pain?”

When you can talk about those things, you can treat the patient from a whole physiologic perspective. For example, how does their sciatica affect their sexual pain? How does their antidepressant cause a delayed orgasm? How does their low testosterone level affect their energy level, their libido, and their desire? 

We see so much shame and guilt in sexual health, to the extent that patients feel broken. We can help them understand the anatomy and physiology and explain that they aren’t broken. Instead, it’s “You need this medicine for your crippling anxiety, and that’s why your orgasm is delayed, and so can we augment it or add or subtract something to help you with it.”

Winter: In a primary care setting, where we are considering the patient›s overall health, we strive for medication compliance, but a huge part of medication noncompliance is sexual side effects, whether it›s antidepressants, beta-blockers, birth control, or this new world of GLP-1 agonists.

Rubin: I would add breast cancer treatments. Many patients go off their anastrozole or their tamoxifen because of the sexual side effects. 

Winter: This is where we get to the crux of this discussion about sex being a vital sign — something you need to check routinely. We need to become comfortable with it, because then we are unlocking the ability to treat every patient like a whole person, give them better outcomes, improve their compliance, and have a really powerful tool for education.

Rubin: We have a growing toolbox for all genders when it comes to sexual health. We have FDA- approved medications for low libido in women. We use testosterone in men in an evidence-based way to safely improve libido. We use medications to help with the genitourinary syndrome of menopause. Orgasm is a challenging one, but we have devices that can help with those reflexes. And working with people who specialize in sexual pain can be extremely helpful for patients.

Dr. Winter, having practiced in different settings, what would you tell the primary care doctors who don’t want to talk about libido or who minimize sexual complaints because they don’t know how to navigate them?

Winter: I do not envy the challenge of being a primary care provider in the healthcare world we are living in. I think it is the hardest job. The ultimate takeaway is to just normalize the conversation and be able to validate what is happening. Have a few basic tools, and then have referrals. It›s not that you have to have all the time in the world or you have to treat every condition, but you have to start the conversation, be comfortable with it, and then get patients hooked up with the right resources.

Rubin: Every doctor of every kind can connect with patients and try to understand what they care about. What are their goals? What do they want for their families, for their relationships, for their quality of life? And how can we work collaboratively as a team to help them with those things? 

Sex is a huge part of people’s lives. If we don’t ask about it; if we don’t look into it; and if we don’t admit that our physiology, our medications, and our surgeries can affect sexual health and functioning, how can we improve people’s lives? We can do so much as a team when we consider sex as a true vital sign.
 

Dr. Rubin, Assistant Clinical Professor, Department of Urology, Georgetown University, Washington, DC, has disclosed ties with Maternal Medical, Absorption Pharmaceuticals, GlaxoSmithKline, and Endo.

When you can talk about those things, you can treat the patient from a whole physiologic perspective. For example, how does their sciatica affect their sexual pain? How does their antidepressant cause a delayed orgasm? How does their low testosterone level affect their energy level, their libido, and their desire? 

We see so much shame and guilt in sexual health, to the extent that patients feel broken. We can help them understand the anatomy and physiology and explain that they aren’t broken. Instead, it’s “You need this medicine for your crippling anxiety, and that’s why your orgasm is delayed, and so can we augment it or add or subtract something to help you with it.”

Winter: In a primary care setting, where we are considering the patient›s overall health, we strive for medication compliance, but a huge part of medication noncompliance is sexual side effects, whether it›s antidepressants, beta-blockers, birth control, or this new world of GLP-1 agonists.

Rubin: I would add breast cancer treatments. Many patients go off their anastrozole or their tamoxifen because of the sexual side effects. 

Winter: This is where we get to the crux of this discussion about sex being a vital sign — something you need to check routinely. We need to become comfortable with it, because then we are unlocking the ability to treat every patient like a whole person, give them better outcomes, improve their compliance, and have a really powerful tool for education.

Rubin: We have a growing toolbox for all genders when it comes to sexual health. We have FDA- approved medications for low libido in women. We use testosterone in men in an evidence-based way to safely improve libido. We use medications to help with the genitourinary syndrome of menopause. Orgasm is a challenging one, but we have devices that can help with those reflexes. And working with people who specialize in sexual pain can be extremely helpful for patients.

Dr. Winter, having practiced in different settings, what would you tell the primary care doctors who don’t want to talk about libido or who minimize sexual complaints because they don’t know how to navigate them?

Winter: I do not envy the challenge of being a primary care provider in the healthcare world we are living in. I think it is the hardest job. The ultimate takeaway is to just normalize the conversation and be able to validate what is happening. Have a few basic tools, and then have referrals. It›s not that you have to have all the time in the world or you have to treat every condition, but you have to start the conversation, be comfortable with it, and then get patients hooked up with the right resources.

Rubin: Every doctor of every kind can connect with patients and try to understand what they care about. What are their goals? What do they want for their families, for their relationships, for their quality of life? And how can we work collaboratively as a team to help them with those things? 

Sex is a huge part of people’s lives. If we don’t ask about it; if we don’t look into it; and if we don’t admit that our physiology, our medications, and our surgeries can affect sexual health and functioning, how can we improve people’s lives? We can do so much as a team when we consider sex as a true vital sign.

Rachel S. Rubin, MD: I’m Dr. Rachel Rubin, a urologist and sexual medicine specialist in the Washington, DC, area. And I am so thrilled because my co-fellow, the brilliant and famous Dr. Ashley Winter, a board-certified urologist and a certified menopause practitioner, who sees patients in our practice from Los Angeles, is joining us today to talk about sex as a vital sign.

Ashley Winter, MD: To have the best sexual function, you need many different systems to work. You need your hormones to be in the right place. You need your blood vessels to dilate when you want them to. You need your nerves to connect to your genitalia to make them responsive. The way people say, “The eyes are the window into the soul” — well, the genitals are the window into the cardiovascular system, the peripheral nervous system, and the hormonal system. It’s so dynamic. Patients can understand how this reflects their health. We just need healthcare providers to hammer home how those things connect.

Rubin: If you’re a primary care doctor seeing a patient and you want to educate them on diabetes or high blood pressure, how can you “ ‘sell it with ‘sex”? How can you use sex to educate them about these important medical conditions?

Winter: I hate using it as a fear tactic, but sometimes you have to. Time and again, I’ve seen men with severe profound erectile dysfunction at a young age, with chronically uncontrolled diabetes.

Diabetes can impair the peripheral nerves, resulting in peripheral neuropathy. The same way that it can affect the fingers and toes, diabetes can affect the penis, even before those other areas. Diabetes can also lead to other conditions such as low testosterone, which also affects the function of the penis.

I’m being brutally honest when I tell patients that diabetes control is critical to having a wonderful sexspan — the duration of your life where you’re able to be sexually active and have great sex and do it in the way that you want.

Chronic conditions such as high cholesterol or hypertension can affect your ability to become erect or aroused whether you have a penis or a vulva, and even your ability to have an orgasm.

Rubin: None of my doctors has ever asked me about these issues. But we have to bring them up with patients because they›re not going to bring them up to us. I always say in the review of systems, we shouldn›t just ask, “Do you have any sexual problems?” (which nobody ever does) and move past the question about men, women or both. We should be asking, “Do you have any issues with libido? Do you want to talk about it? Any issues with erection, arousal, orgasm, or sexual pain?”

When you can talk about those things, you can treat the patient from a whole physiologic perspective. For example, how does their sciatica affect their sexual pain? How does their antidepressant cause a delayed orgasm? How does their low testosterone level affect their energy level, their libido, and their desire? 

We see so much shame and guilt in sexual health, to the extent that patients feel broken. We can help them understand the anatomy and physiology and explain that they aren’t broken.

TOPLINE:

Deprescribing antihypertensive medications is associated with a 12% lower likelihood of cognitive decline in older nursing home residents, a new study suggests. The association was strongest among those with dementia.

METHODOLOGY:

• The cohort study included 12,644 long-term care residents (mean age, 77.7 years; 97% men; 17.5% Black) with stays of at least 12 weeks from 2006 to 2019.
• Residents who experienced either a reduction in the total number of antihypertensive medications or a sustained 30% decrease in dosage for at least 2 weeks were classified as deprescribing users (n = 1290). Those with no medication changes were considered stable users (n = 11,354).
• The primary outcome was cognitive impairment assessed using the four-point Cognitive Function Scale (CFS), with the score proportional to the severity of impairment.
• The median follow-up duration was 23 weeks for the deprescribing users and 21 weeks for the stable users.

TAKEAWAY:

• Deprescribing antihypertensives was associated with a 12% lower likelihood of progressing to a worse CFS score per 12-week period (odds ratio [OR], 0.88; 95% CI, 0.78-0.99), compared with stable users.
• Among residents with dementia, deprescribing was associated with a 16% reduced likelihood of cognitive decline per 12-week period (OR, 0.84; 95% CI, 0.72-0.98).
• At the end of follow-up, 12% of residents had a higher CFS score and 7.7% had a lower CFS score.
• In the intention-to-treat analysis, the association between deprescribing antihypertensive medications and reduced cognitive decline remained consistent (OR, 0.94; 95% CI, 0.90-0.98).

IN PRACTICE:

“This work highlights the need for patient-centered approaches to deprescribing, ensuring that medication regimens for older adults are optimized to preserve cognitive function and minimize potential harms,” the study authors wrote.

SOURCE:

The study was led by Bocheng Jing, MS, Department of Medicine, University of California, San Francisco. It was published online in JAMA Internal Medicine.

LIMITATIONS:

The study population included predominantly men and White individuals, limiting the generalizability of the results to women and other racial and ethnic groups. The findings may not be applicable to patients with heart failure owing to their noninclusion. The specificity of dementia diagnosis was limited, as this study combined various forms of dementia, making it challenging to differentiate the impacts among subgroups.

DISCLOSURES:

This study was supported by the US National Institute on Aging. Two authors reported receiving grants, honoraria, consulting fees, or royalties from various sources. Details are provided in the original article.

This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication. A version of this article first appeared on Medscape.com.

Coffee and tea are among the plants that are highest in caffeine. Their use as beverages makes caffeine the most consumed psychoactive agent in the world. Coffee is commonly used to increase alertness and work productivity. Synthetic caffeine is added to soft drinks, energy drinks, and products intended to reduce fatigue or promote weight loss.

The caffeine content varies with the type of drink: It is high in coffee, energy drinks, and caffeine tablets; intermediate in tea; and low in soft drinks. Coffee is the predominant source of the caffeine ingested by adults. The evidence for caffeine’s effects on people is ambiguous, and some risks and benefits deserve special attention because of the impact they may have on our health.
 

Characteristics of Caffeine

Caffeine is a methylxanthine that is completely absorbed 45 minutes after ingestion, peaking between 15 minutes and 2 hours. The half-life of caffeine varies according to age. In adults, it is 2.5-4.5 hours; in newborns, 80 hours; in children older than 6 months, it remains stable over time with respect to weight. Smoking accelerates caffeine metabolism by reducing the half-life by 50%. Oral contraceptives, however, double caffeine’s half-life. Caffeine metabolism is reduced during pregnancy (it is greater in the first trimester), with a half-life of more than 15 hours. Caffeine clearance can be slowed by several classes of drugs (eg, quinolones, cardiovascular drugs, bronchodilators, and antidepressants) that increase its half-life because they are metabolized by the same liver enzymes.

Caffeine passes the blood-brain barrier and, having an adenosine-like structure, inhibits adenosine’s effects by binding to adenosine receptors. In the brain, caffeine reduces fatigue, increases alertness, reduces reaction times, may reduce the risk for depression, and increases the effectiveness of nonsteroidal anti-inflammatory drugs in treating headaches and other types of pain.
 

Caffeine and Chronic Diseases

The evidence available on the relationship between caffeine and health has several methodological limitations. Observations of the acute effects of caffeine may not reflect long-term effects because tolerance to caffeine’s effects may develop over time. Smoking and unhealthy lifestyles are confounding factors in epidemiological studies of caffeine intake. In addition, the estimate of the amount and frequency of caffeine intake is often inaccurate because it is mainly based on self-assessment systems. Finally, prospective studies of caffeine consumption are mainly based on coffee and tea consumption, but it is unclear how much the observed outcomes can be translated to intake of other beverages such as energy drinks.

Considering the very high prevalence of arterial hypertension worldwide (31.1% of adults), many questions have been raised about the influence of coffee consumption on blood pressure (BP) and the risk for arterial hypertension. Administration of 200-300 mg caffeine is shown to induce a mean increase of 8.1 mm Hg systolic BP and 5.7 mm Hg diastolic BP. The increase is observed in the first hour after caffeine intake and lasts no longer than 3 hours.

Yet, the moderate and usual consumption of coffee does not increase, but may even reduce, the risk of developing high BP. In contrast, occasional coffee consumption can have hypertensive effects, and moderate and usual consumption in patients with high BP does not appear to increase the risk for uncontrolled BP and can reduce the risk for death from any cause. The inverse association between coffee consumption and hypertension risk was confirmed in a review and meta-analysis of cross-sectional and cohort studies.

With respect to lipid metabolism, cholesterol levels may increase after caffeine consumption because of cafestol. Concentrations of cafestol are high in unfiltered coffee, intermediate in espresso and moka pot coffee, and negligible in instant or filtered coffee. Studies on the impact of coffee on lipid levels have led to inconsistent results, however. Data have shown that people who drink more coffee have higher triglycerides, total cholesterol, and low-density lipoprotein cholesterol (LDL-C) levels. Other data have shown that caffeine promotes LDL receptor expression and clearance of LDL cholesterol.

Experimental and cohort studies have not shown an association between coffee consumption and atrial fibrillation (AF). In fact, evidence suggests that coffee consumption tends to reduce the risk for AF in a dose-response relationship. Similarly, coffee consumption is not associated with increased risk for cardiovascular events in the general population or among patients with a history of hypertension, diabetes, or cardiovascular disease.

The Coffee and Real-Time Atrial and Ventricular Ectopy study evaluated the acute effects of coffee consumption on cardiac ectopy using wearable sensors with continuous recording. It did not demonstrate any increase in daily premature atrial contractions with coffee consumption, compared with abstaining from caffeine. 

In patients with type 2 diabetes, a study performed in Japan showed that coffee consumption was associated with reduced all-cause mortality. The results suggested a dose-response relationship, and drinking coffee and green tea appeared to reduce mortality risk further. The results were not generalizable, however, because of the study population’s ethnic homogeneity.
 

Dose and Toxicity

Caffeine at high doses (> 400 mg daily) and in susceptible patients can induce anxiety, but the effects of caffeine on sleep and anxiety can differ from patient to patient. This variation reflects differences in caffeine metabolism rate and adenosine receptor gene variants.

High caffeine intake can stimulate diuresis, but without causing damaging effects on hydration when taking moderate doses of caffeine (≤ 400 mg daily) for long periods. Stopping caffeine suddenly, in a regular consumer, can lead to withdrawal symptoms such as headache, asthenia, decreased attention, depressed mood, and flu-like symptoms.

The toxic effects of caffeine occur with intake > 1.2 g. A dose of 10-14 g is considered fatal. Caffeine overdose is rare when considering traditional methods of intake (coffee and tea) because 70-100 cups of coffee should be sufficient for caffeine poisoning. Severe events can occur following the use of caffeine tablets or as energy drinks for the following reasons:

• The episodic consumption of caffeine does not allow for tolerance to develop.
• Young people are more vulnerable to the effects of caffeine.
• Caffeine has a synergistic effect in combination with other components in energy drinks.
• Taking caffeine in combination with alcohol or intense exertion causes serious, even fatal, outcomes.

Products Containing Caffeine

Evidence supports the relationship between high consumption (approximately 1 L) of energy drinks with a caffeine content of 320 mg and short-term cardiovascular adverse events, such as increased BP, QT-segment prolongation corrected for heart rate, and palpitations. These tests prompt the recommendation to avoid consuming these beverages in high quantities and in association with alcohol.

Weight loss products generally contain caffeine coupled with herbal extracts that are expected to improve fat metabolism, lipolysis, and oxidation. These products, because of their easy availability, presumed benefits, and high caffeine concentration, may be more susceptible to misuse because they can be taken in larger portions than recommended. The combination of multiple ingredients, concentrated amounts of caffeine, and excessive consumption increases the likelihood of adverse effects.

Finally, prospective studies of caffeine consumption are mainly based on coffee and tea consumption, but it is unclear how much the observed outcomes can be translated to intake of other beverages such as energy drinks.

Considering the very high prevalence of arterial hypertension worldwide (31.1% of adults), many questions have been raised about the influence of coffee consumption on blood pressure (BP) and the risk for arterial hypertension. Administration of 200-300 mg caffeine is shown to induce a mean increase of 8.1 mm Hg systolic BP and 5.7 mm Hg diastolic BP. The increase is observed in the first hour after caffeine intake and lasts no longer than 3 hours.

Yet, the moderate and usual consumption of coffee does not increase, but may even reduce, the risk of developing high BP. In contrast, occasional coffee consumption can have hypertensive effects, and moderate and usual consumption in patients with high BP does not appear to increase the risk for uncontrolled BP and can reduce the risk for death from any cause. The inverse association between coffee consumption and hypertension risk was confirmed in a review and meta-analysis of cross-sectional and cohort studies.

With respect to lipid metabolism, cholesterol levels may increase after caffeine consumption because of cafestol. Concentrations of cafestol are high in unfiltered coffee, intermediate in espresso and moka pot coffee, and negligible in instant or filtered coffee. Studies on the impact of coffee on lipid levels have led to inconsistent results, however. Data have shown that people who drink more coffee have higher triglycerides, total cholesterol, and low-density lipoprotein cholesterol (LDL-C) levels. Other data have shown that caffeine promotes LDL receptor expression and clearance of LDL cholesterol.

Experimental and cohort studies have not shown an association between coffee consumption and atrial fibrillation (AF). In fact, evidence suggests that coffee consumption tends to reduce the risk for AF in a dose-response relationship. Similarly, coffee consumption is not associated with increased risk for cardiovascular events in the general population or among patients with a history of hypertension, diabetes, or cardiovascular disease.

The Coffee and Real-Time Atrial and Ventricular Ectopy study evaluated the acute effects of coffee consumption on cardiac ectopy using wearable sensors with continuous recording. It did not demonstrate any increase in daily premature atrial contractions with coffee consumption, compared with abstaining from caffeine. 

In patients with type 2 diabetes, a study performed in Japan showed that coffee consumption was associated with reduced all-cause mortality. The results suggested a dose-response relationship, and drinking coffee and green tea appeared to reduce mortality risk further. The results were not generalizable, however, because of the study population’s ethnic homogeneity.
 

Dose and Toxicity

Caffeine at high doses (> 400 mg daily) and in susceptible patients can induce anxiety, but the effects of caffeine on sleep and anxiety can differ from patient to patient. This variation reflects differences in caffeine metabolism rate and adenosine receptor gene variants.

High caffeine intake can stimulate diuresis, but without causing damaging effects on hydration when taking moderate doses of caffeine (≤ 400 mg daily) for long periods. Stopping caffeine suddenly, in a regular consumer, can lead to withdrawal symptoms such as headache, asthenia, decreased attention, depressed mood, and flu-like symptoms.

The toxic effects of caffeine occur with intake > 1.2 g. A dose of 10-14 g is considered fatal. Caffeine overdose is rare when considering traditional methods of intake (coffee and tea) because 70-100 cups of coffee should be sufficient for caffeine poisoning. Severe events can occur following the use of caffeine tablets or as energy drinks for the following reasons:

• The episodic consumption of caffeine does not allow for tolerance to develop.
• Young people are more vulnerable to the effects of caffeine.
• Caffeine has a synergistic effect in combination with other components in energy drinks.
• Taking caffeine in combination with alcohol or intense exertion causes serious, even fatal, outcomes.

Products Containing Caffeine

Evidence supports the relationship between high consumption (approximately 1 L) of energy drinks with a caffeine content of 320 mg and short-term cardiovascular adverse events, such as increased BP, QT-segment prolongation corrected for heart rate, and palpitations. These tests prompt the recommendation to avoid consuming these beverages in high quantities and in association with alcohol.

Weight loss products generally contain caffeine coupled with herbal extracts that are expected to improve fat metabolism, lipolysis, and oxidation. These products, because of their easy availability, presumed benefits, and high caffeine concentration, may be more susceptible to misuse because they can be taken in larger portions than recommended. The combination of multiple ingredients, concentrated amounts of caffeine, and excessive consumption increases the likelihood of adverse effects.

BOSTON — The use of sodium-glucose cotransporter-2 (SGLT2) inhibitors is associated with reduced short- and long-term mortality among patients with pulmonary arterial hypertension (PAH), according to results from a new propensity score–matched analysis.

“There are a lot of new studies that show benefits [of SGLT2 inhibitors] in heart failure, in [chronic kidney disease], and of course, in diabetes. Group one pulmonary hypertension includes not only the inflammatory cascades but also fibrotic and neurovascularization, and all these different parts of the pathophysiology are linked to each other. There are studies that show that SGLT2 inhibitors can have an impact on inflammatory cascades, fibrosis, and vascular remodeling in general. Together, all this data triggered this idea for me, and that’s when I decided to conduct further studies,” said Irakli Lemonjava, MD, who presented the study at the American College of Chest Physicians (CHEST) 2024 Annual Meeting.

The researchers drew data on 125,634 adult patients from the TriNetX database who were diagnosed with PAH after January 1, 2013. They used propensity score matching to account for demographic characteristics and 10 organ system disorders to compare patients with exposure to SGLT2 inhibitors (canagliflozin, dapagliflozin, empagliflozin, or ertugliflozin; n = 6238) with those without such exposure (n = 6243).

At 1 year, 8.1% of patients taking SGLT2 inhibitors had died, compared with 15.5% of patients not taking SGLT2 inhibitors (risk reduction [RR], 0.52; P < .0001). The values were 13% and 22.5% (RR, 0.579; P < .0001) at 3 years and 14.6% and 25% at 5 years (RR, 0.583; P < .0001).

The study generated discussion during the Q&A period following the talk. One audience member asked if the group was able to access patients both inside and outside the United States. “Because I wonder if access to GLP2 inhibitors is actually a surrogate marker for access to other medications,” the questioner said.

Although the finding is intriguing, it shouldn’t change clinical practice, according to Lemonjava. “I don’t think we can make any changes based on what I shared today. Our purpose was to trigger the question. I think the numbers are so impressive that it will trigger more studies. I think if in the future it’s demonstrated by clinical trials that [SGLT2 inhibitors are beneficial], it will not be a problem to prescribe for someone with pulmonary arterial hypertension because they do not have many side effects,” he said. Lemonjava is a resident physician at Jefferson Einstein Philadelphia Hospital, Philadelphia.

Session co-moderator said Syed Rehan Quadery, MD, praised the study but emphasized the remaining uncertainty. “It’s an excellent proof of concept study. More trials need to [be done] on it, and we don’t understand the mechanism of action in which it improves survival in patients with pulmonary artery hypertension. The majority of the patients with pulmonary hypertension are much older and they have comorbidities, including cardiovascular risk factors, and maybe that is one of the ways in which this drug helps. Plus, there are multiple mechanisms in which it may be working, including anti-inflammatory as well as antiproliferative mechanisms through inhibiting the Notch-3 signaling pathway,” said Quadery, who is a consultant respiratory physician at National Pulmonary Hypertension Unit, Dublin, Ireland.

Quadery and his co-moderator Zeenat Safdar, MD, both noted that SGLT2 inhibitors have already been demonstrated to improve outcomes in heart failure. “[SGLT2 inhibition] improves survival, it decreases hospitalization, it improves morbidity and mortality. There are a lot of things that can be shown in different [animal or in vitro] models. In humans, we actually don’t know exactly how it works, but we know that it does. If it works in left heart failure, it also [could] work in right heart failure,” said Safdar, who is the director of the Houston Methodist Lung Center, Houston Methodist Hospital, Houston.

The study was independently supported. Lemonjava, Quadery, and Safdar reported no relevant financial relationships.

Common arm positions for blood pressure (BP) measurements that stray from guidelines — arm in lap or hanging at side — led to substantial overestimation of hypertension in a study published in JAMA Internal Medicine.

Guidelines for BP measurement recommend arm support on a desk with the midcuff at heart level. Overestimating BP can lead to unnecessary patient follow-up and overtreatment. Hypertension affects approximately 86 million  adults in the United States and more than 1 billion people globally.

This study has widespread implications given the number of settings where BP checks are performed and the growth in patients taking their own BP readings at home, said Donald DiPette, MD, who was not part of the research and was asked to comment on the findings. Dr. DiPette is the Distinguished Health Sciences Professor at the School of Medicine, University of South Carolina, Columbia.
 

Substantial Overestimation

In the crossover, randomized trial of 133 adults, Hairong Liu, MHS, with the Department of Epidemiology, Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, and colleagues found that supporting the arm on the lap overestimated systolic BP (SBP) by 3.9 mmHg and diastolic BP (DBP) by 4.0 mm Hg. When the arm hung at the side, readings overestimated SBP by 6.5 mm Hg and DBP by 4.4 mm Hg, with consistent results across subgroups.

Participants were randomly assigned to get a series of BP measurements with the arm positioned in three ways: Supported on a desk; hand supported on lap; and arm unsupported at the side. Because BP readings are intrinsically variable, all had a fourth set of BP measurements with the arm supported on a desk. 

Participants’ mean age was 57 years; 48 participants (36%) had SBP of ≥ 130 mm Hg; and 55 participants (41%) had a body mass index of ≥ 30.

Two researcher team staff members conducted all the measurements. They received standardized training and completed a certification test in BP measurement, administered by a study author. Measurements were taken from 9 am to 6 pm using a validated oscillometric BP device (ProBP 2000 Digital Blood Pressure Device, Welch Allyn). Only the right arms were used unless a specific condition was present, such as an open sore.
 

Study’s Design Sets It Apart

The authors wrote that the design of the study set this work apart. “Earlier studies have shown that unsupported or arm positioning below heart level can overestimate SBP by 4-23 mm Hg and DBP by 3-12 mm Hg.” But the strength of this study is the randomized, crossover design, “which is in contrast to the majority of published studies where the order of arm positions before seated BP measurement was not randomized or not clearly described.”

Dr. DiPette, who says, “I’ve given my career to understanding hypertension,” praised the design as well.

Randomization of which position patients were assigned to first was important because the first reading is often higher than subsequent readings, Dr. DiPette said.

“That makes sense as the person acclimatizes to the environment,” he explained. BP can even vary within the same reading, he noted.
 

Incorrect Readings for Many Reasons

Incorrect measures are common given the number of settings and number of providers and patients taking blood pressure even with training, certification in the method, and educational materials.

“We recommend taking a blood pressure in any possible setting you can. Because it’s that critical,” he said. “Most of the time it’s taken in busy primary care settings. The pressures are there. Most times it’s only one reading. It’s the medical environment of today.”

He noted that although this study finds overestimation, different arm positions not recommended by guidelines could potentially result in underestimation of hypertension. 

“I liken the BP measurement to a laboratory test that has clear treatment implications. We would want the BP measurement to have the same rigorous accuracy as a blood test or radiologic machine,” he said. 

Dr. DiPette said more education is needed for patients as well as providers as patients may be monitoring their own BP at home. Patients should also know they can ask for a measurement to be repeated, know the correct arm position recommended by guidelines, and the implications of incorrect readings, he said.

This study was supported by Resolve to Save Lives, which is funded by Bloomberg Philanthropies, the Bill and Melinda Gates Foundation, and Gates Philanthropy Partners, which is funded with support from the Chan Zuckerberg Foundation. 

Ms. Liu reported grants from Resolve to Save Lives outside the submitted work. One coauthor reported grants from the National Institutes of Health and personal fees from Kowa, RhythmX AI, and Fukuda Denshi outside the submitted work. Dr. DiPette declared no relevant financial relationships. He was part of a leadership team that developed World Health Organization guidelines on hypertension.

LONDON — Single-pill combinations that include three or four antihypertensive medications are the way forward for the management of patients with elevated blood pressure, according to experts evaluating the new approach.

This multidrug strategy — in which ultralow-dose triple combinations can be used as a starting treatment and four full-dose combinations can be used to treat resistant hypertension — has shown an impressive ability to lower blood pressure in several new studies.

But will it catch on as a routine treatment recommendation in current practice?

Studies of treatment strategies that involve an ultralow quarter dose of three drugs that lower blood pressure and then escalation to a half-dose triple combination and then to a full-dose triple combination, all given as a single pill, were presented at the European Society of Cardiology (ESC) Congress 2024. Another strategy presented involves a four-drug full-dose combination in patients with resistant hypertension.
 

Start With Low Doses of Three Drugs

The triple-combination pill contains telmisartan (an angiotensin blocker), amlodipine (a calcium channel blocker), and indapamide (a diuretic). The three medications are used at three doses: Quarter, half, and standard.

“The idea is to start treatment with a little bit of the three main drug classes instead of the full dose of one drug and then to increase the triple-combination doses as required to get to blood pressure goal,” said Anthony Rodgers, PhD, from the team at The George Institute for Global Health, Sydney, Australia, that is developing this triple-combination product.

“Using three different mechanisms right from the beginning covers all the bases and leads to improved blood pressure reduction while just using very small doses of each agent. This represents a completely new approach that could transform the management of hypertension,” he reported.

Single-pill triple-combination antihypertensive formulations exist already, but the component drugs are all at standard doses. Such combinations were designed to improve adherence in patients with hard-to-control blood pressure who need more than two full-dose medications, he explained.

“We are suggesting a completely different concept using much lower doses of the triple combination right from the beginning of treatment,” Dr. Rodgers explained. “Convenience and adherence will be an added advantage, but there’s more to it than that. It’s about combining the different mechanisms of three separate drug classes to get a better antihypertensive effect and being able to do this right from the start of treatment in patients with mildly elevated blood pressure, as well as those with higher levels.”

Proof-of-concept trials of this approach have been conducted, but no commercial low-dose triple-combination product has been available.

The George Institute is now developing such a product — through George Medicines, its commercial arm — with the aim of bringing the triple-combination pill to market in both high- and low-income countries. An approval submission has been filed in the United States.

Dr. Rodgers presented two studies that assessed the triple combination. One showed that the quarter dose reduced blood pressure significantly better than placebo in patients with mildly elevated blood pressure. The second showed that half and standard doses of the three medications were more effective at lowering blood pressure than three dual combinations at the same doses.
 

The VERONICA Trial

The triple combination was also assessed in the VERONICA study, which showed that among Black adults in Nigeria with uncontrolled hypertension, blood pressure was lower and control was better with the low-dose triple-combination pill than with standard care, and tolerability was good.

In VERONICA, recently published in JAMA, 300 patients with a mean baseline blood pressure of 151/97 mm Hg at home and 156/97 mm Hg in the clinic were randomly assigned to receive the triple-combination pill or standard care.

In the triple-combination group, patients started with the quarter-dose pill, then accelerated, as necessary, to the half-dose and standard-dose pills.

In the standard care group, patients started with amlodipine (5 mg), which was stepped up at monthly intervals so patients could achieve a target blood pressure < 140/90 mm Hg as follows: Amlodipine (5 mg) plus losartan (50 mg); then amlodipine (10 mg) plus losartan (100 mg); then amlodipine (10 mg), losartan (100 mg), plus hydrochlorothiazide (25 mg); and finally referral to a specialist if the target blood pressure was still not achieved.

At month 6, mean home systolic blood pressure was, on average, 31 mm Hg lower in the triple-combination group and 26 mm Hg lower in the standard care group (adjusted difference, −5.8 mm Hg; P < .001).

More patients in the triple-combination group than in the standard care group achieved clinic blood pressure control, defined as blood pressure < 140/90 mm Hg (82% vs 72%), and more patients achieved home blood pressure control, defined as blood pressure below 130/80 mm Hg (62% vs 28%).

No participants discontinued treatment due to adverse events, and adverse events of special interest were reported by just 2% and 3% patients in the triple-combination and standard care groups, respectively.

At month 6, however, more participants in the triple-combination group than in the standard care group had serum potassium levels < 3.5 mmol/L (34% vs 18%), although fewer participants in both the groups had potassium levels < 3.0 mmol/L (10% vs 5%).

Hypokalemia may be the consequence of low dietary potassium intake in Africa, and co-administration with potassium-enriched salt substitution should be evaluated, said Dike Ojji, MBBS, PhD, University of Abuja, Nigeria, who was the lead investigator of VERONICA.

“These findings have broad clinical and public health implications, given that improved hypertension control is a priority in Africa and globally. The results underscore the need for combination therapy to be the cornerstone of effective treatment regimens,” Dr. Ojji said.
 

Missed Targets

“It has taken a long time for the penny to drop as to why the existing antihypertensive treatment paradigm does not work so well,” Dr. Rodgers pointed out. “What tends to happen in clinical practice is that people start on one drug and blood pressure falls a bit, then no further action is taken. But this is not usually enough to get to target. With our approach of using three drugs at low doses straight away, we can often get the blood pressure controlled to target much more quickly with one tablet.”

Low doses of the triple-combination pill should also have a favorable adverse-effect profile and fewer drug interactions, as these issues are generally seen much more frequently with higher doses of drugs, he explained.

This low-dose triple-combination approach could help manage the current epidemic of hypertension and cardiometabolic disease, said Pam Taub, MD, director of preventive cardiology at UC San Diego Health System.

“We are in a new era of cardiometabolic disease, and one of the fundamental drivers of atherosclerotic cardiovascular disease is hypertension, which is prevalent in patients with diabetes, in those with obesity, and is a contributor to chronic kidney disease,” she said.

“We really need to be addressing hypertension very early to prevent this end-organ damage, but because hypertension tends to occur alongside multiple other comorbidities, patients are often on many different medications and are overwhelmed by the burden of polypharmacy.”

Dr. Taub described this triple-combination approach as “looking at hypertension treatment through a new lens.”

“We’ve always been taught to maximize the dose of one agent before we go to a new agent,” she said. “These studies are fundamentally challenging that paradigm. From a pathophysiological and mechanistic perspective, we are seeing that lower doses of different medications can really harness some unique synergistic mechanisms, which can be beneficial for patients.”

But not all experts are convinced that this approach will be a popular option in all countries.

Although this approach makes sense, in that the different agents work synergistically to give a better antihypertensive effect, many physicians could be uncomfortable with the idea of giving multiple medications straight off as the first step of treatment, said Eugene Yang, MD, from the University of Washington in Seattle.

If the patient develops a side effect, it will not be clear which medication is causing it, making it difficult to know which one to stop, he pointed out.

“These studies confirm that a low-dose multidrug-combination pill is effective at lowering blood pressure, but we already have previous studies showing this,” he added. “The issue is how we translate this into patient care. It would be great if we could get people to use it, but I think concerns from both clinicians and patients about identifying the source of any side effects may be a stumbling block.”

The approach is more likely to be adopted in low- to middle-income countries, where there is limited access to healthcare and where the population-wide control of blood pressure makes sense, said Dr. Yang.

Most current guidelines now recommend initiating therapy with two agents, ideally, as a single-pill combination product. “We have finally acknowledged that the vast majority of patients need two drugs. That’s a good starting point. This low-dose triple combination could be an interesting new approach,” said Neil Poulter, MD, professor of preventive cardiovascular medicine at Imperial College London, England.

This approach is in line with the idea that single-pill combinations are the way forward for hypertension therapy, he added.

“The triple combination is attractive, in that you are never quite sure which particular mechanism is driving an individual’s elevated blood pressure, so if you can target three different mechanisms at the same time, you’ve got more chance of a good hit,” Dr. Poulter said.

“The VERONICA trial showed a very good result on lowering BP using this low-dose triple combination as a starting point and increasing quickly to single-pill combinations of triple half doses, then triple full doses, as required. But I think we need more evidence on how this compares to current practice than just this one study in Africa to make this an acceptable routine approach on a global level,” he said.
 

QUADRO: Four-Drug Combo in Resistant Hypertension

Another scenario in which single-pill antihypertensive combinations could be particularly useful is at the other end of the spectrum: The treatment of patients with resistant hypertension.

The QUADRO study showed that a single pill containing perindopril, indapamide, amlodipine, and bisoprolol is better at lowering blood pressure than the triple combination of perindopril, indapamide, and amlodipine.

The primary endpoint — office sitting systolic blood pressure at 16 weeks — was 8 mm Hg lower with the quadruple combination than with the triple combination. And mean ambulatory 24-hour systolic blood pressure was 7.5 mm Hg lower with the four-drug combination.

This was the first study of a single-pill quadruple combination in patients with resistant hypertension, which is a “difficult-to-treat condition demanding a high number of pills with not enough safe and practical options,” said Stefano Taddei, MD, from the University of Pisa, Italy, when he presented the study at the ESC meeting.

Using “four well-established drugs in a single-combination pill may improve adherence and should be an innovative solution for resistant and difficult-to-treat hypertensive patients,” he said.

Nonadherence is a big problem in patients with resistant hypertension. “It is really difficult to get patients to take three or four antihypertensive agents along with all the other medications they have for other comorbidities,” Dr. Taub pointed out. “We really need to think about combination formulations that reduce the pill burden for our patients.”

Around 10% patients with hypertension may require a fourth drug, so a four-drug single-pill combination therefore makes good sense, said Dr. Poulter.

But the choice of the fourth drug is the subject of debate. The PATHWAY trial showed spironolactone to be the most effective fourth agent, but it can cause side effects, such as gynecomastia and hyperkalemia.

“The beta-blocker in the four-drug combination product used in the QUADRO study may not be as effective as spironolactone at lowering blood pressure,” Dr. Poulter explained, noting that beta-blockers have known side effects. However, “they are often already recommended for patients with very common comorbidities, such as arrhythmias, history of MI, heart failure, angina. In that regard, it makes sense to have a beta-blocker in there.”

The four-drug combination used in the QUADRO study led to a bigger reduction — by 8 mm Hg — than the three-drug combination. “That’s pretty good. I thought this was a very useful and interesting study,” he said.

There could be a role for a four-drug combination product in resistant hypertension. “Whatever we can do to improve adherence and reduce blood pressure is good thing,” said Dr. Yang.

However, a mineralocorticoid receptor antagonist (such as spironolactone) might be better as the fourth drug; that is what is recommended in the resistant hypertension algorithm.
 

Lower Blood Pressure, Better Outcomes

“What we are seeing in these trials is that across a wide spectrum of patients with hypertension or resistant hypertension, combination pills are superior to standard practice for BP lowering, and that will lead to improved outcomes,” said Dr. Taub.

“For years, such single-pill combinations have been viewed as ‘bad medicine’ in hypertension,” Dr. Poulter added. “That is clearly not the case, as these studies are showing. And single-pill combination therapies are used extensively in practically every other area of medicine. We are starting to accept them now in the blood pressure community, and I think the use of triple and quadruple combinations, as in these studies, has a real logic to it. But for this approach to be useful, these single-pill combinations must be made available, cheaply, across the world, especially in low- and middle-income countries where hypertension rates are a particular problem.”

LONDON — Single-pill combinations that include three or four antihypertensive medications are the way forward for the management of patients with elevated blood pressure, according to experts evaluating the new approach.

This multidrug strategy — in which ultralow-dose triple combinations can be used as a starting treatment and four full-dose combinations can be used to treat resistant hypertension — has shown an impressive ability to lower blood pressure in several new studies.

But will it catch on as a routine treatment recommendation in current practice?

Studies of treatment strategies that involve an ultralow quarter dose of three drugs that lower blood pressure and then escalation to a half-dose triple combination and then to a full-dose triple combination, all given as a single pill, were presented at the European Society of Cardiology (ESC) Congress 2024. Another strategy presented involves a four-drug full-dose combination in patients with resistant hypertension.
 

Start With Low Doses of Three Drugs

The triple-combination pill contains telmisartan (an angiotensin blocker), amlodipine (a calcium channel blocker), and indapamide (a diuretic). The three medications are used at three doses: Quarter, half, and standard.

“The idea is to start treatment with a little bit of the three main drug classes instead of the full dose of one drug and then to increase the triple-combination doses as required to get to blood pressure goal,” said Anthony Rodgers, PhD, from the team at The George Institute for Global Health, Sydney, Australia, that is developing this triple-combination product.

“Using three different mechanisms right from the beginning covers all the bases and leads to improved blood pressure reduction while just using very small doses of each agent. This represents a completely new approach that could transform the management of hypertension,” he reported.

Single-pill triple-combination antihypertensive formulations exist already, but the component drugs are all at standard doses. Such combinations were designed to improve adherence in patients with hard-to-control blood pressure who need more than two full-dose medications, he explained.

“We are suggesting a completely different concept using much lower doses of the triple combination right from the beginning of treatment,” Dr. Rodgers explained. “Convenience and adherence will be an added advantage, but there’s more to it than that. It’s about combining the different mechanisms of three separate drug classes to get a better antihypertensive effect and being able to do this right from the start of treatment in patients with mildly elevated blood pressure, as well as those with higher levels.”

Proof-of-concept trials of this approach have been conducted, but no commercial low-dose triple-combination product has been available.

The George Institute is now developing such a product — through George Medicines, its commercial arm — with the aim of bringing the triple-combination pill to market in both high- and low-income countries. An approval submission has been filed in the United States.

Dr. Rodgers presented two studies that assessed the triple combination. One showed that the quarter dose reduced blood pressure significantly better than placebo in patients with mildly elevated blood pressure. The second showed that half and standard doses of the three medications were more effective at lowering blood pressure than three dual combinations at the same doses.

The triple combination was also assessed in the VERONICA study, which showed that among Black adults in Nigeria with uncontrolled hypertension, blood pressure was lower and control was better with the low-dose triple-combination pill than with standard care, and tolerability was good.

“The beta-blocker in the four-drug combination product used in the QUADRO study may not be as effective as spironolactone at lowering blood pressure,” Dr. Poulter explained, noting that beta-blockers have known side effects. However, “they are often already recommended for patients with very common comorbidities, such as arrhythmias, history of MI, heart failure, angina. In that regard, it makes sense to have a beta-blocker in there.”

The four-drug combination used in the QUADRO study led to a bigger reduction — by 8 mm Hg — than the three-drug combination. “That’s pretty good. I thought this was a very useful and interesting study,” he said.

There could be a role for a four-drug combination product in resistant hypertension. “Whatever we can do to improve adherence and reduce blood pressure is good thing,” said Dr. Yang.

However, a mineralocorticoid receptor antagonist (such as spironolactone) might be better as the fourth drug; that is what is recommended in the resistant hypertension algorithm.
 

Lower Blood Pressure, Better Outcomes

“What we are seeing in these trials is that across a wide spectrum of patients with hypertension or resistant hypertension, combination pills are superior to standard practice for BP lowering, and that will lead to improved outcomes,” said Dr. Taub.

“For years, such single-pill combinations have been viewed as ‘bad medicine’ in hypertension,” Dr. Poulter added. “That is clearly not the case, as these studies are showing. And single-pill combination therapies are used extensively in practically every other area of medicine. We are starting to accept them now in the blood pressure community, and I think the use of triple and quadruple combinations, as in these studies, has a real logic to it. But for this approach to be useful, these single-pill combinations must be made available, cheaply, across the world, especially in low- and middle-income countries where hypertension rates are a particular problem.”

MADRID — Emerging data points to the urgent need for cardiovascular risk reduction in all adults with type 1 diabetes (T1D), including those who are young and those diagnosed in adulthood.

At the European Association for the Study of Diabetes (EASD) 2024 Annual Meeting, two entire oral abstract sessions were devoted to research examining cardiovascular risk specifically in people with T1D. There is increasing evidence that as with type 2 diabetes (T2D), clinical visits need to focus on other cardiovascular risk factors and glucose.

Findings included the evidence of severe coronary artery disease (CAD) in asymptomatic adults with T1D, increased risks for mortality and cardiac events in people diagnosed with T1D in adulthood, and a greater cardiovascular risk for those with overweight/obesity and among those with more cumulative exposure to both hyperglycemia and dyslipidemia.

One speaker, Dr. Rebecka Johanna Bergdal, of the Folkhälsan Research Center and the University of Helsinki, Finland, issued a “call to action,” saying, “We call on healthcare professionals to continue supporting and encouraging individuals with T1D towards better management of diabetes, including both glucose and lipid management.”

Session Moderator Krzysztof Strojek, MD, PhD, head of the Department of Internal Medicine, Diabetology and Cardiometabolic Diseases at the Medical University of Silesia, Katowice, Poland, told this news organization that all the data point in the same direction for T1D management, to “look not only at A1c and blood glucose control but also lipids, hypertension, smoking status, all these risk factors recognized in type 2 ... are also important in T1D.”
 

The ‘Alarming’ Finding of CAD in Asymptomatic Patients

Michal Dubsky, MD, PhD, of the Diabetes Centre, Institute for Clinical and Experimental Medicine, Prague, Czech Republic, presented findings from 62 asymptomatic patients with T1D for > 10 years (mean, 36 years), with a mean A1c of 7.5% (58 mmol/mol), and no prior history of cardiovascular disease (CVD). They had slightly elevated CVD biomarkers, including a mean low-density lipoprotein (LDL) cholesterol level of 2.33 mmol/L, lipoprotein (a) level of 15 nmol/L, and N-terminal pro-B-type natriuretic peptide level of 125.3 ng/L. 

All underwent a noninvasive carotid ultrasound and coronary artery calcium (CAC) scoring. Of those, 12 patients had a CAC score > 400 and/or presence of two or more carotid plaques identified as high-risk.

Those 12 patients underwent coronary angiography and had a total of 29 vessels examined by optical coherence tomography (OCT), “an invasive intravascular method for assessing coronary atherosclerosis that is far more sensitive than standard coronary angiography, especially for the detection of high-risk vulnerable plaques without a hemodynamically significant stenosis,” Dr. Dubsky explained.

Coronary angiography showed obstructive CAD in 5 of the 12 patients. Their mean calcium score was 950 and mean number of carotid plaques was 2.8. Features associated with plaque vulnerability included microphage accumulation in 24 vessels, lipid-rich plaques in 23, spotty calcium in 19, and neovascularizations in 13.

Thin-cap fibroatheroma, a strong predictor of plaque rupture, was present in 7 of the 12 patients (58.3%), and four had features of very high-risk plaques, defined as thin-cap fibroatheroma with a minimal lumen area < 3.5 mm², a lipid arch > 180 degrees, and macrophages. 

“Our study showed that asymptomatic T1D patients with high CAC score and carotid plaques had very severe OCT findings. We observed a significant proportion of high-risk lesions potentially associated with plaque rupture and risk of CV death. Therefore, we believe these patients should be treated as very high-risk with target LDL below 1.4 mmol/L (55 mg/dL), even though they are completely asymptomatic,” Dr. Dubsky concluded.

He added that because OCT is invasive and costly, the CAC score can be used to guide the decision for statin use, with any score above 100 considered elevated risk. 

Study coauthor Martin Haluzik, MD, professor of internal medicine in the Charles University, Prague, Czech Republic, told this news organization, “I think it’s very alarming because some of these are basically very healthy-looking young people, so you don’t really expect them to have significant cardiovascular complications already or significant plaques. I think it shows that we should be more proactive in looking into the risk of cardiovascular complications and in looking into the early cardiovascular changes.”
 

Later Diagnosis Doesn’t Always Protect: Risk Seen in Adult-Onset T1D

Yuxia Wei, a PhD student at the Institute of Environmental Medicine, Karolinska Institutet, Stockholm, Sweden, presented an analysis of data from Sweden’s national health databases comparing cardiovascular outcomes between 10,184 people diagnosed with T1D at ages 18-29 years, 30-39 years, and ≥ 40 years; another 375,523 people diagnosed with T2D at those ages; and 509,172 population controls matched for age, sex, and county.

Those diagnosed after age 40 years had higher A1c levels and were less likely to be using insulin pumps than those diagnosed at younger adult ages. 

Compared with population controls, at a median of about 7 years of follow-up, people with T1D had significantly higher all-cause mortality at all diagnosis age groups, with a hazard ratio of 1.71. This rose to 2.78 for those diagnosed at age 30-39 years.

Compared with those with T2D, the mortality risks weren’t significantly different at any age, but the risks for non-cardiovascular death, including from cancer and infection, were significantly higher among those diagnosed after age 40 years (1.31 overall). Those diagnosed with T1D at any adult age had lower risks for major cardiovascular events than those diagnosed with T2D. Hazard ratios ranged from 0.27 for those diagnosed at age 18-29 years to 0.78 for those diagnosed after the age of 40 years.

Smoking and A1c above target were the greatest contributors to mortality. Those two factors, along with body mass index (BMI), were the strongest contributors to major adverse cardiovascular events (MACE).

“Adult-onset T1D carries excess risk of death and cardiovascular disease, without obvious attenuation over age at diagnosis…Smoking, A1c, and BMI are the key factors to be managed to improve prognosis in adult-onset T1D,” Ms. Wei concluded.
 

BMI: Often Overlooked in T1D, but a Major CVD Risk Factor

Two studies examined the link between overweight/obesity and cardiovascular risk in T1D. One, by Laurence Salle, MCU PH, of the Endocrinology, Diabetes and Metabolic Diseases Department at CHU Limoges, France, was a prospective, longitudinal cohort study of 2367 people with T1D at 68 centers in France who didn’t have a cardiovascular history at baseline.

Of those, 51% had normal BMI (18.5-24.9), 31% had overweight (25-29.9), and 18% had obesity (≥ 30). Cardiovascular risk factors, including LDL cholesterol, triglycerides, and hypertension increased with an increasing BMI. The 10-year CVD risk was significantly higher for those with overweight (9.61%) and obesity (9.93%) than for those with normal weight (7.24%), in both men and women. 

However, BMI was found to be an independent predictor of 10-year high cardiovascular risk in men but not women, while waist:height ratio independently predicted risk in both men and women, Dr. Salle reported.

The second BMI study, from Enrique Soto-Pedre, MBBS, of the Division of Population Health and Genomics at the University of Dundee, Scotland, presented data on a retrospective follow-up from 1995 to 2019 of 1973 people with T1D aged > 18 years at diagnosis (42% women; mean age, 34.2 years; 18.9% had obesity.

After 10 years of follow-up, those with overweight and obesity had significantly higher odds of developing arterial hypertension, even among those taking angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, with statistically significant adjusted hazard ratios of 1.73 and 3.37 for the obese and overweight groups, respectively. 

MACE were significantly more common among those with obesity, with an adjusted hazard ratio of 2.95, as was acute myocardial infarction, 3.33. 

“These results emphasize the importance of incorporating weight management into the overall management of individuals with T1D. No one has doubts about weight management in T2D, but in type 1, it’s not so clear. One of the main [concerns] would be safety [in terms of hypoglycemia],” Dr. Soto-Pedre concluded. 
 

Call for Action: Cumulative Glucose and Lipid Exposures Increase Risk

Dr. Bergdal presented data on the effects of cumulative glycemia and lipids on the risk for CAD in 3495 adults with T1D who had been diagnosed prior to the age of 40 years. The history of CAD or stroke was exclusion criteria. There were a total of 534 CAD events within a median follow-up of 19.4 years.

Cumulative glycemia, LDL cholesterol, triglycerides, and non–high-density lipoprotein cholesterol exposures were all significantly associated with CAD risk (P < .001 for all). With an adjustment for confounders, the highest tertile of glycemia was associated with a twofold increased risk for CAD. Both hyperglycemia and dyslipidemia were independently associated with CAD risk, Dr. Bergdal reported. 

“It’s important to minimize the time spent above A1c 7%, and lipid management in T1D must not be forgotten,” she said, prior to issuing her call for action.

Dr. Haluzik reported receiving honoraria for talks and/or consultancy and/or research funding from Eli Lilly, Novo Nordisk, Sanofi, AstraZeneca, Mundipharma, Bristol Myers Squibb, Amgen, Boehringer Ingelheim, Janssen, Ypsomed, and Johnson & Johnson. The presenters had no disclosures.

Air pollution, high temperatures, and metabolic risk factors are driving global increases in stroke, contributing to 12 million cases and more than 7 million deaths from stroke each year, new data from the Global Burden of Disease (GBD) study showed.

Between 1990 and 2021, the number of people who experienced a stroke increased to 11.9 million (up by 70% since 1990), while the number of stroke survivors rose to 93.8 million (up by 86%), and stroke-related deaths rose to 7.3 million (up by 44%), making stroke the third leading cause of death worldwide after ischemic heart disease and COVID-19, investigators found.

Stroke is highly preventable, the investigators noted, with 84% of the stroke burden in 2021 attributable to 23 modifiable risk factors, including air pollution, excess body weight, high blood pressure, smoking, and physical inactivity.

This means there are “tremendous opportunities to alter the trajectory of stroke risk for the next generation,” Catherine O. Johnson, MPH, PhD, co-author and lead research scientist at the Institute for Health Metrics and Evaluation (IHME), University of Washington, Seattle, said in a news release.

The study was published online in The Lancet Neurology.
 

Top Risk Factor for Subarachnoid Hemorrhage

Since 1990, the contribution of high temperatures to poor health and early death due to stroke has risen 72%, a trend likely to increase in the future — underscoring the impact of environmental factors on the growing stroke burden, the authors said.

“Given that ambient air pollution is reciprocally linked with ambient temperature and climate change, the importance of urgent climate actions and measures to reduce air pollution cannot be overestimated,” Dr. Johnson said.

Mitchell S.V. Elkind, MD, MS, chief clinical science officer for the American Heart Association, who wasn’t involved in the study, told this news organization that environmental factors such as air pollution, particulate matter from wildfires and other sources, and excessive heat are now recognized as major contributors to the risk for stroke. “This should not be surprising as we have long recognized the risks of stroke associated with toxins in cigarette smoke, which likely share mechanisms for vascular damage with pollutants,” Dr. Elkind said.

The data also reveal for the first time that ambient particulate matter air pollution is a top risk factor for subarachnoid hemorrhage, contributing to 14% of the death and disability caused by this serious stroke subtype, on a par with smoking.

Dr. Elkind noted that smoking is “a major risk factor for subarachnoid hemorrhage. It makes sense that particulate air pollution would therefore similarly be a risk factor for subarachnoid hemorrhage, which similarly damages blood vessels. Prior studies were likely too small or did not assess the role of air pollution in subarachnoid hemorrhage.”

The analysis also showed substantial increases between 1990 and 2021 in the global stroke burden linked to high body mass index (up by 88%), high blood sugar (up 32%), a diet high in sugar-sweetened drinks (up 23%), low physical activity (up 11%), high systolic blood pressure (up 7%), and a diet low in omega-6 polyunsaturated fatty acids (up 5%).

“And with increasing exposure to risk factors such as high blood sugar and diet high in sugar-sweetened drinks, there is a critical need for interventions focused on obesity and metabolic syndromes,” Dr. Johnson said.

“Identifying sustainable ways to work with communities to take action to prevent and control modifiable risk factors for stroke is essential to address this growing crisis,” she added.
 

Prevention Strategies Fall Short

The data also showed that stroke-related disability-adjusted life-years rose from around 121.4 million years of healthy life lost in 1990 to 160.5 million years in 2021, making stroke the fourth leading cause of health loss worldwide after COVID-19, ischemic heart disease, and neonatal disorders.

“The global growth of the number of people who develop stroke and died from or remain disabled by stroke is growing fast, strongly suggesting that currently used stroke prevention strategies are not sufficiently effective,” lead author Valery L. Feigin, MD, PhD, from Auckland University of Technology, Auckland, New Zealand, and affiliate professor at IHME, said in the release.

“New, proven effective population-wide and motivational individual prevention strategies that could be applied to all people at risk of having a stroke, regardless of the level of risk, as recommended in the recent Lancet Neurology Commission on Stroke should be implemented across the globe urgently,” said Dr. Feigin.

Dr. Elkind said the AHA supports research on the effects of air quality on risk for vascular injury and stroke and has “long advocated for policies to mitigate the adverse health impacts of air pollutants, including reduction of vehicle emissions and renewable portfolio standards, taking into account racial, ethnic, and economic disparities.”

“AHA, and the healthcare sector more broadly, must take a leadership role in recommending policies to improve environmental air quality and in working with the private sector and industry to improve air quality,” Dr. Elkind said.

In an accompanying commentary, Ming Liu, MD, and Simiao Wu, MD, PhD, West China Hospital, Sichuan University, Chengdu, China, wrote that “pragmatic solutions to the enormous and increasing stroke burden include surveillance, prevention, acute care, and rehabilitation.”

“Surveillance strategies include establishing a national-level framework for regular monitoring of stroke burden, risk factors, and healthcare services via community-based surveys and health records,” they noted.

“Artificial intelligence and mobile technologies might not only facilitate the dissemination of evidence-based health services but also increase the number of data sources and encourage participation of multidisciplinary collaborators, potentially improving the validity and accuracy of future GBD estimates,” they added.

Air pollution, high temperatures, and metabolic risk factors are driving global increases in stroke, contributing to 12 million cases and more than 7 million deaths from stroke each year, new data from the Global Burden of Disease (GBD) study showed.

Between 1990 and 2021, the number of people who experienced a stroke increased to 11.9 million (up by 70% since 1990), while the number of stroke survivors rose to 93.8 million (up by 86%), and stroke-related deaths rose to 7.3 million (up by 44%), making stroke the third leading cause of death worldwide after ischemic heart disease and COVID-19, investigators found.

Stroke is highly preventable, the investigators noted, with 84% of the stroke burden in 2021 attributable to 23 modifiable risk factors, including air pollution, excess body weight, high blood pressure, smoking, and physical inactivity.

This means there are “tremendous opportunities to alter the trajectory of stroke risk for the next generation,” Catherine O. Johnson, MPH, PhD, co-author and lead research scientist at the Institute for Health Metrics and Evaluation (IHME), University of Washington, Seattle, said in a news release.

The study was published online in The Lancet Neurology.
 

Top Risk Factor for Subarachnoid Hemorrhage

Since 1990, the contribution of high temperatures to poor health and early death due to stroke has risen 72%, a trend likely to increase in the future — underscoring the impact of environmental factors on the growing stroke burden, the authors said.

“Given that ambient air pollution is reciprocally linked with ambient temperature and climate change, the importance of urgent climate actions and measures to reduce air pollution cannot be overestimated,” Dr. Johnson said.

I’d like to talk about a recent report in the journal Menopause linking menopausal symptoms to increased risk for cognitive impairment. I’d also like to discuss some of the recent studies that have addressed whether hot flashes are linked to increased risk for heart disease and other forms of cardiovascular disease (CVD). 

Given that 75%-80% of perimenopausal and postmenopausal women have hot flashes and vasomotor symptoms, it’s undoubtedly a more complex relationship between hot flashes and these outcomes than a simple one-size-fits-all, yes-or-no question.

Increasing evidence shows that several additional factors are important, including the age at which the symptoms are occurring, the time since menopause, the severity of the symptoms, whether they co-occur with night sweats and sleep disruption, and the cardiovascular status of the woman.

Several studies suggest that women who have more severe hot flashes and vasomotor symptoms are more likely to have prevalent cardiovascular risk factors — hypertension, dyslipidemia, high body mass index, endothelial dysfunction — as measured by flow-mediated vasodilation and other measures.

It is quite plausible that hot flashes could be a marker for increased risk for cognitive impairment. But the question remains, are hot flashes associated with cognitive impairment independent of these other risk factors? It appears that the associations between hot flashes, vasomotor symptoms, and CVD, and other adverse outcomes, may be more likely when hot flashes persist after age 60 or are newly occurring in later menopause. In the Women’s Health Initiative observational study, the presence of hot flashes and vasomotor symptoms in early menopause was not linked to any increased risk for heart attack, stroke, total CVD, or all-cause mortality.

However, the onset of these symptoms, especially new onset of these symptoms after age 60 or in later menopause, was in fact linked to increased risk for CVD and all-cause mortality. With respect to cognitive impairment, if a woman is having hot flashes and night sweats with regular sleep disruption, performance on cognitive testing would not be as favorable as it would be in the absence of these symptoms.

This brings us to the new study in Menopause that included approximately 1300 Latino women in nine Latin American countries, with an average age of 55 years. Looking at the association between severe menopausal symptoms and cognitive impairment, researchers found that women with severe symptoms were more likely to have cognitive impairment.

Conversely, they found that the women who had a favorable CVD risk factor status (physically active, lower BMI, healthier) and were ever users of estrogen were less likely to have cognitive impairment.

Clearly, for estrogen therapy, we need randomized clinical trials of the presence or absence of vasomotor symptoms and cognitive and CVD outcomes. Such analyses are ongoing, and new randomized trials focused specifically on women in early menopause would be very beneficial.

At the present time, it’s important that we not alarm women about the associations seen in some of these studies because often they are not independent associations; they aren’t independent of other risk factors that are commonly linked to hot flashes and night sweats. There are many other complexities in the relationship between hot flashes and cognitive impairment.

We need to appreciate that women who have moderate to severe hot flashes (especially when associated with disrupted sleep) do have impaired quality of life. It’s important to treat these symptoms, especially in early menopause, and very effective hormonal and nonhormonal treatments are available.

For women with symptoms that persist into later menopause or who have new onset of symptoms in later menopause, it’s important to prioritize cardiovascular health. For example, be more vigilant about behavioral lifestyle counseling to lower risk, and be even more aggressive in treating dyslipidemia and diabetes.

Manson, Professor of Medicine and the Michael and Lee Bell Professor of Women’s Health, Harvard Medical School; Chief, Division of Preventive Medicine, Brigham and Women’s Hospital, Boston, Massachusetts; and Past President, North American Menopause Society, 2011-2012, has disclosed the following relevant financial relationships: Received study pill donation and infrastructure support from Mars Symbioscience (for the COSMOS trial).
