Direct-to-consumer telemedicine services that provide gender-affirming hormone therapy appear to follow evidence-based guidelines and charge about the same as brick-and-mortar medical centers, according to researchers who reviewed the platforms’ websites.

The findings suggest that virtual care “may be a good option” for transgender, nonbinary, and intersex people, who often report difficulty finding physicians they trust, Erin Jesse, MD, a fifth-year urology resident at University Hospitals Cleveland Medical Center, who is the first author of the study, told this news organization.

Dr. Jesse’s group presented their findings at a joint scientific meeting of the Sexual Medicine Society of North America and the International Society for Sexual Medicine in Miami. The results have not been published in a peer-reviewed journal.

New direct-to-consumer telemedicine companies have emerged with gender-diverse staff and services tailored to the needs of these individuals. They offer “a more inclusive feel” than might be encountered at a physician’s office, Dr. Jesse said.

Confirming that these companies adhere to standards of care and cost-effectiveness “is especially important considering the reduced access to care and potentially increased vulnerability of the gender-diverse population,” she and her colleagues wrote.

From a Google search in March, the team identified six U.S.-based platforms that offer gender-affirming medical therapy: FOLX, True U Clinic, QueerDoc, Queer Med, TransClinique, and Plume.

From information posted on the companies’ websites, the researchers determined that all aligned with the World Professional Association for Transgender Health’s Standards of Care in two areas: use of an informed consent model to ensure that patients have sufficient information and understanding to decide on their own treatment and endorsement of frequent laboratory monitoring of hormone levels in early stages of treatment.

The team also compared the costs listed on the websites for the first year of therapy to the costs of similar care at a tertiary center, as determined using University Hospitals Cleveland Medical Center’s online estimator.

The platforms offered various pricing models, including fee-for-service and monthly membership plans ranging from $59 to $139. For individuals without insurance, estimates ranged from $1,022 to $1,428 for oral estradiol and from $1,184 to $1,668 for intramuscular testosterone from the online companies, compared with $1,184 and $1,216, respectively, at the tertiary center.

Although some platforms accept insurance, the researchers were not able to evaluate the cost of using private insurance or Medicaid, Dr. Jesse said. She noted that transgender individuals are more likely to lack insurance than are cisgender patients.

The team also assessed the scope of services. All companies offered legal help with changes to names and gender markers, such as “M” and “F.” Three or more companies offered preexposure prophylaxis to prevent HIV infection, treatment for erectile dysfunction, referrals for surgery, and medical letters of support for surgery.

Two offered puberty blockers, although the researchers were unable to determine the risk of adolescents obtaining treatment without proper assessments, because details of those services are not disclosed on websites, Dr. Jesse said.

An avenue of further research would be to interview patients to learn how platforms operate in practice and whether patients are properly assessed before treatment. “Those sorts of questions we can’t answer just by looking at the websites,” she said.

However, Charlotte Hoffman, JD, senior policy counsel for the National Center for Transgender Equality, an advocacy group, said she does not harbor concerns about patients being treated inappropriately simply because care is virtual. All clinicians who provide gender-affirming care face potential repercussions, such as malpractice lawsuits or state disciplinary action, if they veer from treatment guidelines, she said.

“I don’t necessarily take the premise that telehealth is inherently worse than in-person care as a given,” Ms. Hoffman said.

During the COVID-19 pandemic, Ms. Hoffman added, direct-to-consumer telemedicine has expanded access for individuals in rural areas, people with disabilities, and those who live in places where in-person providers of transgender care face public hostility, although individuals without the resources to pay may still be left out.

What might happen to that access if telemedicine restrictions that were loosened during the pandemic are reinstated is unclear, she said.

The researchers and Ms. Hoffman have disclosed no relevant financial relationships.

Epstein-Barr Virus (EBV) is a suspect in the development of multiple sclerosis (MS), and recent research developments have strengthened that connection. In 2022, two studies received quite a bit of attention. One showed that EBV seroconversion occurs in the years prior to MS diagnosis in virtually every patient, and that serum levels of the neuronal damage biomarker neurofilament light (NfL) rose following EBV infection. Another paper showed anti-EBNA (Epstein-Barr nuclear antigen) antibodies in the cerebrospinal fluid cross-react with the central nervous system antigen GlialCAM in some MS patients.

Based on those studies, “it’s tempting to speculate that primary EBV infection could be a trigger to the autoimmune process suspected for MS,” said Tilman Schneider-Hohendorf, PhD, during a presentation at the annual meeting of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS).

Dr. Schneider-Hohendorf, who is a postdoctoral fellow at the University of Münster, Germany, presented a new study that added more evidence that EBV may be a key player in MS pathogenesis. He and colleagues conducted a genetic analysis of patient T cells and found evidence that EBV viral activity may be occurring during MS.
 

A viral pathway to MS

Asked for comment, Bruce Cree, MD, PhD, said: “I think it is a very interesting one, because what we know about EBV is that it’s a risk factor for MS. So many studies performed over the last 20 years have shown a very strong association between EBV infection and the occurrence of MS. Studies have shown quite conclusively that EBV infection precedes MS in almost every patient, and that EBV infection is followed by a rise in serum NfL, which is a biomarker of neuronal damage. You have EBV infection, and then typically several years later a rise in serum concentrations of this marker of neuronal injury, and this is all in a presymptomatic state. Then that is followed by the onset of clinical symptoms in MS. That temporal sequence, I think, is very convincing,” said Dr. Cree, who is a professor of clinical neurology at the University of California, San Francisco.

He pointed out that EBV is not the sole causal pathway of MS, since genetic and environmental factors are known to be involved. “Nonetheless, it’s very strong evidence to indicate that this virus is involved in disease pathogenesis,” said Dr. Cree.

The new research takes the work a step further by revealing a population of T cells in MS patients that appear to be responding directly to EBV during active viral disease. That could be telling because most people who experience an EBV infection and experience mononucleosis recover, and some never even realize they have been infected. As a herpes virus, EBV remains in a latent state in B cells and other immune cells. “We know that you need an EBV infection (to trigger MS), but is EBV in some way continuing to be active in MS?” said Dr. Cree.

Other groups have looked for such evidence, but results have been mixed. Dr. Cree’s own group looked for evidence of EBV in spinal fluid of MS patients when they first present with symptoms, and could find no evidence. On the other hand, an autopsy study of MS patients has found evidence of chronic EBV infection in and around the brain, including the meninges, which could implicate the B cells found in that region. Another study found EBV-targeting antibodies that cross react with neuronal antigens in the cerebral spinal fluid of MS patients. “So depending on the assay used and the types of investigation, there is variable evidence to indicate that EBV has a role in ongoing MS pathogenesis – that it isn’t just a risk factor for MS that triggers the disease but potentially has a role in determining the course of MS,” said Dr. Cree.
 

IS EBV part of MS pathogenesis?

The new study presented at ECTRIMS by Dr. Schneider-Hohendorf offered evidence that MS patients have excess CD8-positive T cells that recognize EBV antigens typically shed during active viral infection. The results suggest “that the immune system is responding to that chronic infection,” said Dr. Cree.

The findings have some implications for a clinical study now in progress, called EMBOLD, which is looking at whether a heterologous infusion of T cells that have been primed to attack EBV could improve symptoms of progressive MS. “The hypothesis there is that chronically infected cells within the body are causing progressive MS and that if we could eradicate those cells, both within the central nervous system and within the periphery, perhaps we could see improvement in MS functional outcomes,” said Dr. Cree, who is a co-investigator for the EMBOLD study. The trial is using T cells from donors that are matched for the human leukocyte antigen complex, which is hoped will target and kill EBV-infected cells.

The study presented by Dr. Schneider-Hohendorf supports the approach. “There is an implication from this study that the trial that that’s currently being conducted might actually possibly have a benefit in the sense that there’s now another piece of evidence to indicate that EBV is not only a risk factor for MS, but may actually participate during the course of the disease as part of the pathogenesis,” said Dr. Cree.

In the new study, the researchers sequenced the T-cell receptor variable beta-chain (TRBV) peripheral repertoire among three cohorts of MS patients: A discovery cohort with 1,336 patients with MS and 229 controls; a validation cohort with 59 patients with MS and 51 controls; and 35 monozygotic twins who were discordant for MS. They identified sequences known to bind to EBV, SARS-CoV-2, cytomegalovirus, and influenza A, and used the latter three viruses as a proof of concept to demonstrate the validity of the approach. EBV-specific MHC-1 restricted CD8 TRBV in the serum of MS patients, with large effect sizes in the discovery (+2.2), validation (+2.1), and MS twin (+1.6) populations. The findings in the twin population rule out a genetic or environmental explanation for the findings in the discovery and validation cohorts, according to Dr. Schneider-Hohendorf.

The researchers also sequenced CSF among six healthy donors and five patients with MS and found significant differences. The T-cell populations had more lytic properties that suggested ongoing immune surveillance. “We can conclude that we found a broader response that could indicate an aberrant immune response. This could be a remnant of disease triggering an event or it could indicate an ongoing immune response to EBV. Is this EBV activity? We really don’t know. To find out, we would expand our pathogen-specific sequences, we would assess CNS tissue and lesions, and we would define the primary response in pediatric cohorts to better understand what might go wrong,” Dr. Schneider-Hohendorf concluded.

Dr. Cree has a financial relationship with Biogen and is a co-investigator for the EMBOLD trial. Dr. Schneider-Hohendorf has financial relationships with Biogen, Novartis, and Roche.

Women continue to be underrepresented among the leadership ranks of dermatology training programs, although the gender gap has closed in recent years, according to a recent cross-sectional study.

Although women made up more than half of the dermatology residency program directors (53.5%), associate directors (62.6%), and assistant directors (58.3%) in 2021, those numbers fall short of women’s majority (65% in 2018) among the trainees themselves, Yasmine Abushukur of Oakland University in Rochester, Mich., and associates said in a research letter.

Advancements were “made in gender diversity within academic dermatology from 2016 to 2021, [but] women remain underrepresented, particularly in leadership of dermatopathology and dermatologic surgery fellowships,” the investigators wrote.

Data gathered from 142 dermatology residency programs accredited by the Accreditation Council for Graduate Medical Education show that progress has been made since 2016, at least among program directors (PDs), of whom 48% were women, according to a previous study. Data on associate and assistant PDs from 2016 were not available to Ms. Abushukur and associates.

At the fellowship program level, women made gains as PDs in dermatopathology (34% in 2016 and 41% in 2021) and pediatric dermatology (64% in 2016 and 76% in 2021), but not in dermatologic surgery, where the proportion held at 26% over the study period. “This disparity is reflective of the general trend in surgery and pathology leadership nationally,” the researchers noted.

Taking a couple of steps up the ladder of authority shows that 39% of dermatology chairs were women in 2021, compared with 23% in 2016. A study published in 2016 demonstrated decreased diversity among academic faculty members as faculty rank increased, and “our data mirror this sentiment by demonstrating a majority of women in assistant and associate PD positions, with a minority of women chairs,” they wrote.

The investigators said that they had no conflicts of interest and no outside funding. Ms. Abushukur’s coauthors were from the departments of dermatology at the Henry Ford Health System, Detroit, and Wayne State University, Dearborn, Mich.

Although women made up more than half of the dermatology residency program directors (53.5%), associate directors (62.6%), and assistant directors (58.3%) in 2021, those numbers fall short of women’s majority (65% in 2018) among the trainees themselves, Yasmine Abushukur of Oakland University in Rochester, Mich., and associates said in a research letter.

Advancements were “made in gender diversity within academic dermatology from 2016 to 2021, [but] women remain underrepresented, particularly in leadership of dermatopathology and dermatologic surgery fellowships,” the investigators wrote.

Data gathered from 142 dermatology residency programs accredited by the Accreditation Council for Graduate Medical Education show that progress has been made since 2016, at least among program directors (PDs), of whom 48% were women, according to a previous study. Data on associate and assistant PDs from 2016 were not available to Ms. Abushukur and associates.

At the fellowship program level, women made gains as PDs in dermatopathology (34% in 2016 and 41% in 2021) and pediatric dermatology (64% in 2016 and 76% in 2021), but not in dermatologic surgery, where the proportion held at 26% over the study period. “This disparity is reflective of the general trend in surgery and pathology leadership nationally,” the researchers noted.

Taking a couple of steps up the ladder of authority shows that 39% of dermatology chairs were women in 2021, compared with 23% in 2016. A study published in 2016 demonstrated decreased diversity among academic faculty members as faculty rank increased, and “our data mirror this sentiment by demonstrating a majority of women in assistant and associate PD positions, with a minority of women chairs,” they wrote.

A new Japanese study of highly purified eicosapentaenoic acid (EPA; icosapent ethyl) has suggested a possible benefit in reducing adverse cardiovascular events in patients with chronic coronary artery disease taking statins.

The open-label randomized RESPECT-EPA study showed a reduction of borderline statistical significance in its primary endpoint of a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal ischemic stroke, unstable angina, and coronary revascularization in patients allocated to the EPA product at a dosage of 1,800 mg/day.

The results were presented at the American Heart Association scientific sessions by Hiroyuki Daida, MD, Juntendo University Graduate School of Medicine, Japan. 

However, the trial has several limitations, including a high number of patient withdrawals or protocol deviations, and as such, its conclusions are uncertain.  

Regardless, it has inevitably added to the debate on the cardiovascular benefits of EPA, which were shown in the REDUCE-IT trial. However, that trial has been dogged with controversy because of concerns that the mineral oil placebo used may have had an adverse effect.

Commenting on the new RESPECT-EPA trial for this article, lead investigator of the REDUCE-IT trial, Deepak Bhatt, MD, said the results were consistent with REDUCE-IT and another previous Japanese trial, the Japan EPA Lipid Intervention Study (JELIS), and added to the evidence supporting cardiovascular benefits of EPA.

“In isolation, this study may not be viewed as showing conclusive benefits, but looking at the totality of the data from this trial and from the field more widely, this together shows a convincing cardiovascular benefit with EPA,” Dr. Bhatt said. “We now have 3 randomized controlled trials all showing benefits of highly purified EPA in reducing cardiovascular events.”

However, long-time critic of the REDUCE-IT trial, Steve Nissen, MD, Cleveland Clinic, was not at all impressed with the RESPECT-EPA trial and does not believe it should be used to support the EPA data from REDUCE-IT. 

“The many limitations of the RESPECT-EPA trial make it uninterpretable. It just doesn’t meet contemporary standards for clinical trials,” Dr. Nissen said in an interview. “I don’t think it sheds any light at all on the debate over the efficacy of EPA in cardiovascular disease.”

Dr. Nissen was the lead investigator of another largescale trial, STRENGTH, which showed no benefit of a different high dose omega-3 fatty acid product including a combination of EPA and docosahexaenoic acid (DHA).  

In his AHA presentation on the RESPECT-EPA study, Dr. Daida explained as background that in 2005, JELIS first demonstrated a beneficial effect of highly purified EPA on cardiovascular outcomes in patients with and without coronary artery disease. 

Recently, optimal medical therapy, particularly with high-intensity statins, has become the gold standard of care for patients with coronary artery disease, but they are still at substantially high residual risk, he noted.

Despite of the evidence provided by JELIS, the conflicting results in recent omega-3 fatty acid trials (REDUCE-IT and STRENGTH) have led to an intense controversy regarding the relevance of EPA intervention on top of the latest optimal medical therapy, Dr. Daida said.

The current study – Randomized trial for Evaluating the Secondary Prevention Efficacy of Combination Therapy Statin and EPA (RESPECT-EPA) – was conducted to determine the effect of highly purified EPA on cardiovascular events in Japanese patients with chronic coronary artery disease and a low EPA/arachidonic acid (AA) ratio (< 0.4), who were already receiving statins.

They were randomly assigned to highly purified EPA (icosapent ethyl, 1,800 mg/day) plus statin therapy or to statin therapy alone.

The enrollment period started in 2013 and continued for 4 years. Patients were followed for a further 4 years from the end of the enrollment period.

The trial included 2,506 patients, 1,249 assigned to the EPA group and 1,257 to the control group. In both groups there were a high number of early withdrawals or protocol deviations (647 in the EPA group and 350 in the control group).

The analysis was conducted on 1,225 patients in the EPA group and 1,235 patients in the control group, although at 6 years’ follow-up there were fewer than 400 patients in each arm.  

Baseline characteristics showed median low-density lipoprotein (LDL) cholesterol levels of 80 mg/dL, EPA levels of 45 mcg/mL, and triglyceride levels of 120 mg/dL.

The primary endpoint, a composite of cardiovascular death, nonfatal MI, nonfatal ischemic stroke, unstable angina, and coronary revascularization showed a borderline significant reduction in the EPA group at 6 years since the start of randomization (10.9% vs. 14.9%; hazard ratio, 0.785; P = .0547).

The secondary endpoint, a composite of sudden cardiac death, MI, unstable angina, and coronary revascularization, showed a significant reduction in the EPA group (8.0% vs. 11.3%; HR, 0.734; P = .0306).

In terms of adverse events, there was an increase in gastrointestinal disorders (3.4% vs. 1.2%) and new-onset atrial fibrillation (3.1% vs. 1.6%) in the EPA group.

In a post hoc analysis, which excluded patients with an increase of more than 30 mcg/mL in the control group (182 patients) and those with an increase of less than 30 mcg/mL in the EPA group (259 patients), the primary endpoint showed a significant reduction the EPA group (HR, 0.725; P = .0202).

Dr. Daida noted that limitations of the study included a lower than expected event rate (suggesting that the study may be underpowered), an open-label design, and the fact that baseline levels of EPA in this Japanese population would be higher than those in Western countries.
 

‘Massive loss’ of patients

Critiquing the study, Dr. Nissen highlighted the large dropout and protocol violation rate.

“There was a massive loss of patients over the 6- to 8-year follow-up, and the Kaplan-Meier curves didn’t start to diverge until after 4 years, by which time many patients had dropped out. It would have been a very selective population that lasted 6 years in the study. Patients that drop out are different to those that stay in, so they are cherry-picking the patients that persist in the trial. There is enormous bias here,” he commented. 

“Another weakness is the open-label design. Everyone knew who is getting what. Blinding is important in a study. And there was no control treatment in this trial,” he noted.

The researchers also selected patients with low EPA levels at baseline, Dr. Nissen added. “That is completely different hypothesis to what was tested in the REDUCE-IT and STRENGTH trials. And even with all these problems, the results are still statistically insignificant.”  

On the post hoc subgroup analysis showing a significant benefit, Dr. Nissen said, “they compared a subgroup in the active treatment arm who had large increases in EPA to a subgroup of control patients who had the smallest increase in EPA. That would be like comparing patients who had the largest reductions in LDL in a statin trial to those in the control arm who had no reductions or increases in LDL. That’s scientifically totally inappropriate.”
 

Supportive data

But Dr. Bhatt argues that the RESPECT-EPA trial supports the two previous trials showing benefits of EPA.

“Some may quibble with the P value, but to me this study has shown clear results, with obvious separation of the Kaplan-Meier curves,” he said.  

“It is an investigator-initiated study, which is good in principle but has some of the usual caveats of such a study in that – probably as a consequence of budget constraints – it has an open-label design and is underpowered. But as they did not use a placebo and still showed a benefit of EPA, that helps resolve the issue of the placebo used in REDUCE-IT for those who were concerned about it,” Dr. Bhatt noted.  

He pointed out that the 1,800-mg dose of EPA is the same dose used in the JELIS trial and is the dose used in Japan. The REDUCE-IT trial used a higher dose (4 g), but in general, Japanese people have higher levels of EPA than Western populations, he explained.  

“While this trial included patients with lower levels of EPA, what is considered low in Japan is much higher than average American levels,” he added.
 

Magnitude of benefit uncertain?

Discussant of the study at the Late Breaking Clinical Trials session, Pam R. Taub, MD, professor of medicine at the University of California, San Diego School of Medicine, said, “Despite being underpowered with a sample size of 2,460, RESPECT-EPA shows benefit in decreasing composite coronary events.”

“There is benefit with EPA, but the magnitude of benefit is uncertain,” she stated.

Dr. Taub pointed out that there is a signal across studies for new-onset atrial fibrillation, but the absolute increase is “rather small.”

She noted that more mechanistic and clinical data are needed to hone in on which patients will derive the most benefit, such as those with elevated high-sensitivity C-reactive protein or highest change in EPA levels. But she concluded that in clinical practice, physicians could consider addition of EPA for reduction of residual risk in secondary prevention patients.

The RESPECT-EPA study was supported by the Japan Heart Foundation. Dr. Daida reports peakers’ bureau/honorarium fees from Novartis Pharma, Bayer Yakuhin, Sanofi, Kowa Company, Taisho Pharmaceutical, Abbott Medical Japan, Otsuka Pharmaceutical, Amgen, MSD, Daiichi Sankyo, Pfizer Japan, FUKUDA DENSHI, Tsumura, and TOA EIYO and research funding from Philips Japan, FUJIFILM Holdings, Asahi Kasei, Inter Reha, TOHO HOLDINGS, GLORY, BMS, Abbott Japan, and Boehringer Ingelheim Japan.

CHICAGO – The traditional Chinese herbal medicine tongxinluo added to guideline-directed therapy improves clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI), the CTS-AMI study suggests.

Compared with those assigned to placebo, Chinese patients assigned to tongxinluo had lower rates of 30-day and 1-year major adverse cardiovascular and cerebrovascular events (MACCE), driven by fewer cardiac deaths. Severe STEMI complications were also lower.

Tongxinluo, which contains 10 or more potential active herbs and insects, did not result in severe adverse effects, including major bleeding.

The results were presented at the American Heart Association scientific sessions by Yuejin Yang, MD, PhD, a professor of cardiology at Fuwai Hospital, National Center for CV Disease, Beijing.

He noted that despite reperfusion and optimal medical therapy, patients with STEMI still face high in-hospital mortality, myocardial no-flow, and reperfusion injury, which have no targeted drugs so far worldwide. In addition, “inadequate implementation of timely revascularization for STEMI in China (50-70%) and other developing countries leaves a substantial infarct size in many patients.”

Tongxinluo has been approved for angina and stroke since 1996 in China. Previous preclinical studies and the investigators’ proof-of-concept ENLEAT trial in STEMI suggested tongxinluo could reduce myocardial no-flow and infarction size and protect the cardiomyocytes, Dr. Yang said.

The CTS-AMI trial was conducted at 124 hospitals in mainland China and evenly randomly assigned 3,797 patients with STEMI or new left bundle-branch block within 24 hours of symptom onset to eight capsules of tongxinluo, 2.08 g, or to placebo plus dual antiplatelet therapy before percutaneous coronary intervention (PCI), thrombolysis, or medical management alone, followed by four capsules thrice daily plus guideline-directed therapy for 12 months.

In the modified intention-to-treat cohort of 1,889 tongxinluo- and 1,888 placebo-treated patients, primary PCI was performed in 94.2% and 92.3%, respectively.

The relative risk of 30-day MACCE was reduced 36% in the tongxinluo group, compared with the placebo group (3.39% vs. 5.24%; RR, 0.64; 95% confidence interval, 0.47-0.88).

Among the primary endpoint components, the relative risk of cardiac death was reduced 30% (2.97% vs. 4.24%; RR, 0.70; 95% CI, 0.50-0.99) and MI reinfarction 65% (0 vs. 9 events; RR, 0.35; 95% CI, 0.13-0.99).

Strokes were similar in the tongxinluo and control groups (4 vs. 9; RR, 0.44; 95% CI, 0.14-1.43) and no patient had emergent coronary revascularization at 30 days.

The benefit of the traditional Chinese compound on the primary endpoint was consistent across subgroups, Dr. Yang reported.

At 30 days, severe STEMI complications (11.79% vs. 14.80%; P = .008) and malignant arrhythmias (7.84% vs. 10.20%; P = .011) were lower in the tongxinluo group, whereas mechanical complications (10 vs. 13; P = .526) and cardiogenic shock (2.37% vs. 3.31%; P =.082) were similar.

At 1 year, hazard ratios favored tongxinluo for MACCE (0.64; 95% CI, 0.49-0.82), cardiac death (0.73; 95% CI, 0.55-0.97), MI reinfarction (0.26; 95% CI, 0.10-0.67), and stroke (0.44; 95% CI, 0.21-0.92).

In terms of safety issues, 41 patients receiving tongxinluo and 52 patients receiving placebo had a serious adverse event (2.17% vs. 2.75%; P = .25).

Except for fewer renal injuries with tongxinluo (3.81% vs. 5.30%; P = .029), there were no significant between-group differences in adverse effects including allergic rash, hepatic injury, prolonged activated partial thromboplastin time or prothrombin time, digestive tract hemorrhage, nausea, diarrhea, and headache or dizziness.

“These findings support the use of tongxinluo as an adjunctive therapy in treating STEMI, at least in China and other developing countries,” Dr. Yang concluded.

Invited discussant Kenneth Mahaffey, MD, associate dean, Stanford (Calif.) University, and director of the Stanford Center for Clinical Research, said the results “likely will support use of tongxinluo in China” but that “more studies are needed in other populations and treatment paradigms.”

Asked for further comment by this news organization, Dr. Mahaffey said, “The surprising thing is where are all the MIs? Where are all the revascularization procedures?”

Usually one would expect MIs in about 1% of patients, or about 40 MIs among the 4,000 patients but, he noted, there were zero MIs in the treatment group and 9 among controls.

“We haven’t seen a 30% reduction in cardiovascular death or overall mortality with a therapy in ages with good background therapy,” Dr. Mahaffey said. “We need to see how they ascertained all those events.”

He noted that the results were based on the modified intention-to-treat cohort, which did not include data on 20 patients allocated to treatment, and showed no difference in ST-segment resolution at 2 hours and only a slight difference at 24 hours.

“So even in this trial, for at least some of the data we’ve gotten already that supports the proposed mechanism, it doesn’t show the benefit on that mechanistic substudy. And that’s why we need to see these echoes, the biomarkers, and probably the angios to see: Did it have any effect on the proposed mechanism?” Dr. Mahaffey said.

Finally, information on background therapy is critical for putting the treatment effect into context for other health systems and populations, he said. “Unfortunately, we need to see some additional information to really understand how this will fit in, even in Chinese therapy for STEMI patients, but definitely not outside of China, particularly in the United States, because I don’t know what their background therapy was.”

The study was funded by the National Key Research and Development Program of China. Tongxinluo and placebo were provided by Yiling Pharmacological. The study was designed, conducted, and analyzed independent of the sponsors. Dr. Yang reports no relevant financial conflicts of interest. Dr. Mahaffey reports research funding from the AHA, Apple, Bayer, CIRM, Eidos, Ferring, Gilead, Idorsia, Johnson & Johnson, Luitpold, PAC-12, Precordior, Sanifit, and Verily; consultancy fees from Amgen, Applied Therapeutics, AstraZeneca, CLS Behring, Elsevier, Fibrogen, Inova, Johnson & Johnson, Lexicon, Myokardia, Novartis, Novo Nordisk, Otsuka, Phasebio, Portola, Quidel, Sanofi, and Theravance; and equity in Precordior.

CHICAGO – The traditional Chinese herbal medicine tongxinluo added to guideline-directed therapy improves clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI), the CTS-AMI study suggests.

Compared with those assigned to placebo, Chinese patients assigned to tongxinluo had lower rates of 30-day and 1-year major adverse cardiovascular and cerebrovascular events (MACCE), driven by fewer cardiac deaths. Severe STEMI complications were also lower.

Tongxinluo, which contains 10 or more potential active herbs and insects, did not result in severe adverse effects, including major bleeding.

The results were presented at the American Heart Association scientific sessions by Yuejin Yang, MD, PhD, a professor of cardiology at Fuwai Hospital, National Center for CV Disease, Beijing.

The 2022 CHEST Annual Meeting had several important studies on lung cancer.

Douglas Arenberg, MD, FCCP from the University of Michigan Northville Health Center, reports on content from two papers that focus on the first million persons to have been screened for lung cancer after the initial launch of the American College of Radiology Lung Cancer Screening Registry. The research showed that the medical community is, in fact, doing well in some areas of lung cancer screening but that improvements need to be made in order to reach former tobacco users, who would greatly benefit from these screenings. 

He also highlights a series of studies that were discussed regarding smoking cessation at lung evaluations known as the SCALE Collaboration. Effective smoking interventions could enhance the benefits of lung cancer screening by reducing mortality and morbidity resulting from lung cancer.

Finally, Dr Arenberg shares a series of presentations that highlight how the surgical treatment of early-stage lung cancer is creating significant changes in the standard of care.

Noninvasive ultrasound- and serum-based fibrosis biomarkers have similar prognostic performance to histology for nonalcoholic fatty liver disease (NAFLD), according to new findings presented at the annual meeting of the American Association for the Study of Liver Diseases.

Fibrosis stages and liver stiffness measured by vibration-controlled transient elastography (LSM-VCTE) through FibroScan were significant predictors of event-free survival, said Ferenc Mozes, DPhil, a postdoctoral research assistant at the University of Oxford, England, who has worked on biomarker evaluation of nonalcoholic steatohepatitis (NASH) as a member of the Liver Investigation: Testing Marker Utility in Steatohepatitis (LITMUS) consortium.

“Liver histology is highly prognostic of liver-related outcomes in patients with NAFLD and NASH,” he said. “Not just that, but liver histology is also accepted, and furthermore mandated by the FDA, as a surrogate endpoint in pharmaceutical trials for NASH.”

Surgical site infections are one of the top causes of postoperative morbidity and death worldwide, but there is little agreement and much debate over the most effective wound dressing to improve outcomes and reduce the health care burden.

Recent clinical trials have indicated that transparent, semiocclusive films have advantages over gauze held by adhesive tape.

But current transparent film bandages may become dislodged during activities such as showering, say authors of a pilot study published in the Journal of Wound Care. Patients may not realize the bandage has been disrupted, which can lead to infection.

The paper describes a novel product called DrySee dressing (DSD), which features a liquid indicator that turns blue around the edges if moisture is present.

“Clinicians, patients, and caregivers are alerted to the loss of dressing integrity and can replace the dressing when any portion of the perimeter changes to a blue [color],” the authors explain. “In addition, the dressing turns blue when the central pad is saturated with fluid, allowing the patient or provider to change the dressing.”

DSD is indicated for wounds that have low levels of exudate.
 

Two transparent film dressings compared

Researchers recruited 20 patients from the general population in Pittsburgh, for a small pilot study to test DSD against a comparator film dressing (3M Tegaderm + Pad). The volunteers received “a small stipend,” according to the paper.

A 1.5-centimeter incision was made in both forearms of each volunteer. The forearms were randomized regarding which got which bandage. Both bandages have been cleared by the U.S. Food and Drug Administration as nonsignificant-risk devices.

Volunteers were instructed to wear the dressing and continue their typical activities of daily living.

The average age of the volunteers was 52 years (range, 20-80 years). Among the 20 volunteers, 11 reported no comorbidities, and 45% reported at least one comorbidity.

Most of the volunteers favored DSD over the comparator in a postoperative survey – 75% to 25%, according to the report.

The wear time between the two transparent dressings across all subjects was 1.4 days. There was no difference in wear time, logged by the volunteers, between the two groups.   

There were no infectious complications, the paper states.

The maker, DrySee (Houston), which holds three patents on the product, supported the research with an unrestricted grant.

DrySee CEO Brad Greer told this news organization, “With DrySee, you know when to change your dressing. All other dressings look the same wet, saturated, or dry.”

He said the study confirms what they have seen in practice, adding that the product is unique.

“No one else in the world has this technology,” Mr. Greer said.
 

Surgeons want to see more data

Heather Evans, MD, a general surgeon with the Medical University of South Carolina, MUSC Health, Charleston, who was not involved with the study, praised the color-indicator design and said she liked the bandage’s narrow indication for low-exudate wounds.

She said in an interview, “It’s a lot to put on a layperson to suddenly know how to take care of wounds when you leave the hospital.”

Giving them the confidence that their wound is safe if the blue doesn’t appear “is a really cool concept,” she said.

She said that, although the volunteers included some elderly people and people with conditions such as diabetes that could affect wound healing, the bandage needs to be tested with a bigger trial to see if it is effective outside controlled conditions.

She also said that some occlusive dressings will be more durable and stay on days longer than DSD or the comparator, which may affect the choice for some.

“The average length of dressing time in this study was less than 2 days,” she pointed out.

Jim Rickert, MD, an orthopedic surgeon with Indiana University Health Bedford, who was not involved with the study, agreed that any surgical or wound dressing, including transparent films, can become dislodged, and said, “This type of product has promise but this is a small pilot study. I would want to see results from a trial of actual surgical patients to see if this type of dressing did indeed decrease post-op infections compared to standard dressing materials.”

Not all are convinced either that there is a need to be filled or that DSD will be the right solution.

Therese Duane, MD, a general surgeon with Texas Health Harris Methodist Fort Worth, who was not part of the study, said in an interview that she “has no issues with the current products.”

She added that more information is needed before considering DSD a better solution, including animal studies and use “on very sick patients.”

“Twenty volunteers with cuts on their arm is barely a start for comparison,” she said.

The authors, led by Kristy Breisinger, a research analyst with the SerenaGroup Research Foundation in Cambridge, Mass., acknowledged the limitations, including the small sample size and that the trial was conducted at only one institution. Additionally, the analysis is based on descriptive statistics.

They write that the trial design was chosen “to simulate a real-world setting that is not always achievable in animal studies.”

The research was sponsored by an unrestricted grant from the maker of DSD, DrySee Inc., in Houston.

Mr. Greer is DrySee’s CEO. The authors and Dr. Duane, Dr. Rickert, and Dr. Evans declared no relevant financial relationships.

The wear time between the two transparent dressings across all subjects was 1.4 days. There was no difference in wear time, logged by the volunteers, between the two groups.   

There were no infectious complications, the paper states.

The maker, DrySee (Houston), which holds three patents on the product, supported the research with an unrestricted grant.

DrySee CEO Brad Greer told this news organization, “With DrySee, you know when to change your dressing. All other dressings look the same wet, saturated, or dry.”

He said the study confirms what they have seen in practice, adding that the product is unique.

“No one else in the world has this technology,” Mr. Greer said.
 

Surgeons want to see more data

Heather Evans, MD, a general surgeon with the Medical University of South Carolina, MUSC Health, Charleston, who was not involved with the study, praised the color-indicator design and said she liked the bandage’s narrow indication for low-exudate wounds.

She said in an interview, “It’s a lot to put on a layperson to suddenly know how to take care of wounds when you leave the hospital.”

Giving them the confidence that their wound is safe if the blue doesn’t appear “is a really cool concept,” she said.

She said that, although the volunteers included some elderly people and people with conditions such as diabetes that could affect wound healing, the bandage needs to be tested with a bigger trial to see if it is effective outside controlled conditions.

She also said that some occlusive dressings will be more durable and stay on days longer than DSD or the comparator, which may affect the choice for some.

“The average length of dressing time in this study was less than 2 days,” she pointed out.

Jim Rickert, MD, an orthopedic surgeon with Indiana University Health Bedford, who was not involved with the study, agreed that any surgical or wound dressing, including transparent films, can become dislodged, and said, “This type of product has promise but this is a small pilot study. I would want to see results from a trial of actual surgical patients to see if this type of dressing did indeed decrease post-op infections compared to standard dressing materials.”

Not all are convinced either that there is a need to be filled or that DSD will be the right solution.

Therese Duane, MD, a general surgeon with Texas Health Harris Methodist Fort Worth, who was not part of the study, said in an interview that she “has no issues with the current products.”

She added that more information is needed before considering DSD a better solution, including animal studies and use “on very sick patients.”

“Twenty volunteers with cuts on their arm is barely a start for comparison,” she said.

The authors, led by Kristy Breisinger, a research analyst with the SerenaGroup Research Foundation in Cambridge, Mass., acknowledged the limitations, including the small sample size and that the trial was conducted at only one institution. Additionally, the analysis is based on descriptive statistics.

They write that the trial design was chosen “to simulate a real-world setting that is not always achievable in animal studies.”

The research was sponsored by an unrestricted grant from the maker of DSD, DrySee Inc., in Houston.

Surgical site infections are one of the top causes of postoperative morbidity and death worldwide, but there is little agreement and much debate over the most effective wound dressing to improve outcomes and reduce the health care burden.

Recent clinical trials have indicated that transparent, semiocclusive films have advantages over gauze held by adhesive tape.

But current transparent film bandages may become dislodged during activities such as showering, say authors of a pilot study published in the Journal of Wound Care. Patients may not realize the bandage has been disrupted, which can lead to infection.

The paper describes a novel product called DrySee dressing (DSD), which features a liquid indicator that turns blue around the edges if moisture is present.

“Clinicians, patients, and caregivers are alerted to the loss of dressing integrity and can replace the dressing when any portion of the perimeter changes to a blue [color],” the authors explain. “In addition, the dressing turns blue when the central pad is saturated with fluid, allowing the patient or provider to change the dressing.”

DSD is indicated for wounds that have low levels of exudate.
 

Two transparent film dressings compared

Researchers recruited 20 patients from the general population in Pittsburgh, for a small pilot study to test DSD against a comparator film dressing (3M Tegaderm + Pad). The volunteers received “a small stipend,” according to the paper.

A 1.5-centimeter incision was made in both forearms of each volunteer. The forearms were randomized regarding which got which bandage. Both bandages have been cleared by the U.S. Food and Drug Administration as nonsignificant-risk devices.

Volunteers were instructed to wear the dressing and continue their typical activities of daily living.

The average age of the volunteers was 52 years (range, 20-80 years). Among the 20 volunteers, 11 reported no comorbidities, and 45% reported at least one comorbidity.

Most of the volunteers favored DSD over the comparator in a postoperative survey – 75% to 25%, according to the report.

Response-adapted de-escalation of immunotherapy in patients with advanced melanoma may lead to considerable savings for payers – close to $20,000 per patient – compared with standard immunotherapy, an economic analysis found.

“The rising costs of cancer therapies are becoming untenable for both patients and payers, and there is both clinical and economic benefit to finding less expensive treatment alternatives,” Wolfgang Kunz, MD, University Hospital, Ludwig Maximilian University of Munich, told this news organization.

This economic analysis “highlights that leveraging modern diagnostic capabilities can do just that: Pairing drug regimens with CT-image analysis to optimize dosages can reduce health care costs and improve clinical outcomes,” Dr. Kunz said.

The study was published online in JAMA Dermatology.

While the use of immunotherapies over the past decade has improved the prognosis for patients with advanced melanoma, these drugs come with a hefty price tag.

One potential way to help reduce costs: de-escalate therapy. The ADAPT-IT trial demonstrated similar progression-free and overall survival among patients who received response-adapted ipilimumab discontinuation and those who received standard of care.

In the current analysis, Dr. Kunz and colleagues wanted to understand whether this response-adapted approach was also cost effective.

The team applied economic modeling to data from the ADAPT-IT trial as well as CheckMate 067, in which patients received standard of care four doses of combination ipilimumab-nivolumab followed by nivolumab monotherapy. In the ADAPT-IT trial, patients also initially received the immunotherapy combination but had CT scans to determine their response after two doses; if they responded, patients discontinued ipilimumab and continued with nivolumab monotherapy.

Overall, ADAPT-IT showed that responders could forgo the additional two doses of ipilimumab plus nivolumab while maintaining similar progression-free survival and overall survival seen at 18 months in the CheckMate 067 trial.

The current economic analysis, based on 41 patients from ADAPT-IT and 314 from CheckMate 067, showed a potential reduction in health care costs of $19,891 per patient with the response-adapted approach.

Response-adapted treatment was the cost-effective option in 94% of simulated scenarios.

When extrapolated to 2019 incidence rates of distant melanoma cases, yearly national savings could reach about $58 million.

“In the relatively small space of immunotherapies in advanced melanoma, we hope this analysis motivates clinicians to consider response-adapted treatment,” Dr. Kunz told this news organization.

“On the larger scale, this analysis serves as a stepping stone to more response-guided treatment protocols,” Dr. Kunz added. “With drug costs rising and imaging capabilities growing, more frequent image-guided adjustments are a perfect fit into the personalized care model.”

When applying the cost savings noted in this analysis across all treated patients, “the economic impact may be profound,” said Joseph Skitzki, MD, surgical oncologist, Roswell Park Comprehensive Cancer Center, Buffalo, N.Y., who wasn’t involved in the study. The “financial toxicity of cancer care is increasingly recognized as a potential barrier to optimal outcomes and any measures to mitigate cost may be impactful.”

However, Dr. Skitzki said several caveats need to be considered.

One is that the data included from ADAPT-IT only included 41 patients, compared with 314 patients from CheckMate 067.

“It is possible that a larger real-world study utilizing the ADAPT-IT protocol may not be as favorable in terms of outcomes and could lessen the economic impact of de-escalation, although any form of de-escalation is likely to have a cost benefit,” Dr. Skitzki said in an interview.

A real-world response–adapted de-escalation clinical trial, with an emphasis on costs and a benchmark of similar progression-free and overall survival, should be conducted before the de-escalated option becomes “practice changing,” Dr. Skitzki said.

Jeffrey Weber, MD, PhD, deputy director, Perlmutter Cancer Center, NYU Langone Health, New York, also urged caution in interpreting the results.

“I would not base treatment decisions on a small sampling of 41 patients in the absence of a randomized comparison,” Dr. Weber told this news organization. “Without a proper comparison, I would not advocate using only two doses of ipilimumab-nivolumab to make decisions on treatment.”

Dr. Skitzki added that, while “studies like this one are desperately needed to lessen the economic impact of new and emerging combination immunotherapies,” there is likely also a “disincentive for pharmaceutical companies to conduct this type of research.”

This research had no specific funding. Dr. Kunz and Dr. Skitzki reported no relevant conflicts of interest. Dr. Weber disclosed relationships with Merck, Genentech, AstraZeneca, Pfizer, Regeneron, and GSK, among others, and holds equity in Cytomx, Biond, NexImmune, and Immunomax.

CHICAGO – A stepwise care pathway was associated with a substantial reduction in the number of invasive tests performed and a major improvement in outcomes, relative to usual management, in patients suspected of coronary artery disease (CAD), according to 1-year results of the multinational, randomized PRECISE trial.

The care pathway is appropriate for patients with nonacute chest pain or equivalent complaints that have raised suspicion of CAD, and it is extremely simple, according to the description from the principal investigator, Pamela S. Douglas, MD, given in her presentation at the annual scientific sessions of the American Heart Association.

Ted Bosworth/MDedge News

Unlike the highly complex diagnostic algorithms shunting suspected CAD patients to the vast array of potential evaluations, the newly tested protocol, characterized as a “precision strategy,” divides patients into those who are immediate candidates for invasive testing and those who are not. The discriminator is the PROMISE minimal risk assessment score, a tool already validated.

Those deemed candidates for testing on the basis of an elevated score undergo computed coronary CT angiography (cCTA). In those who are not, testing is deferred.
 

Strategy is simple but effective

Although simple, this pathway is highly effective, judging by the results of the PRECISE trial, which tested the strategy in 2,103 patients at 65 sites in North America and Europe. The primary outcome was a composite of major adverse cardiovascular events (MACE) that included death, nonfatal MI, and catheterization without observed CAD.

After a median follow-up of 11.8 months, the primary MACE endpoint was reached in about 11.3% of those in the usual-care group, which was more than twofold higher than the 4.2% in the precision strategy group. The unadjusted risk reduction was 65% but rose to more than 70% (hazard ratio, 0.29; P < .001) after adjustment for gender and baseline characteristics.

In the arm randomized to the precision strategy, 16% were characterized as low risk and received no further testing. Almost all the others underwent cCTA alone (48%) or cCTA with fractional flow reserve (FFR) (31%). Stress echocardiography, treadmill electrocardiography, and other functional studies were performed in the small proportion of remaining patients.
 

cCTA performed in just 15% of usual care

In the usual-care arm, cCTA with or without FFR was only performed in 15%. More than 80% of patients underwent evaluations with one or more of an array of functional tests. For example, one-third were evaluated with single photon emission CT/PET and nearly as many underwent stress echocardiography testing. Only 7% in usual care underwent no testing after referral.

Within the MACE composite endpoint, almost all the relative benefit in the precision strategy arm was derived from the endpoint of angiography performed without evidence of obstructive CAD (2.6% vs. 10.2%). Rates of all-cause mortality and MI were not significantly different.

Important for the safety and utility of the precision strategy, there “were no deaths or MI events among those assigned deferred testing ” in that experimental arm, according to Dr. Douglas, professor of research in cardiovascular diseases at Duke University, Durham, N.C.

Instead, those in the precision strategy arm were far less likely to undergo catheterization without finding CAD (20% vs. 60%) and far less likely to undergo catheterization without revascularization (28% vs. 70%).

In addition, the group randomized to the precision strategy were more likely to be placed on risk reducing therapies following testing. Although the higher proportion of patients placed on antihypertensive therapy did not reach statistical significance (P = .1), the increased proportions placed on lipid therapy (P < .001) and antiplatelet therapy (P < .001) did.

Citing a study in JAMA Cardiology that found that more than 25% of patients presenting with stable chest pain have normal coronary arteries, Dr. Douglas said that the precision strategy as shown in the PRECISE trial addresses several agreed-upon goals in guidelines from the AHA, the European Society of Cardiology and the U.K.’s National Institute for Health and Care Excellence. These goals include reducing unnecessary testing by risk stratification, improving diagnostic yield of the testing that is performed, and avoiding the costs and complications of unneeded invasive testing.

New protocol called preferred approach

On the basis of these results, Dr. Douglas called the precision strategy “a preferred approach in evaluating patients with stable symptoms and suspected coronary disease.”

Julie Indik, MD, PhD, a professor of medicine at the University of Arizona, Tuscon, said that application of this approach in routine care could have “a major impact on care” by avoiding unnecessary tests with no apparent adverse effect on outcomes.

Although not demonstrated in this study, Dr. Indik suggested that the large number of patients tested for CAD each year – she estimated 4 million visits – means that less testing is likely to have a major impact on the costs of care, and she praised “the practical, efficient” approach of the precision strategy.

Ted Bosworth/MDedge News

Ron Blankstein, MD, director of cardiac computed tomography, Brigham and Women’s Hospital, Boston, also said these data “have both economic and safety implications.” As an AHA-invited discussant of this study, he emphasized that this is a strategy that should only be applied to lower risk patients with no prior history of CAD, but, in this group, he believes these data “will inform future guidelines.”

Dr. Douglas declined to speculate on whether the precision strategy will be incorporated into future guidelines, but she did say that the PRECISE data demonstrate that this approach improves quality of care.

In an interview, Dr. Douglas suggested that this care pathway could provide a basis on which to demonstrate improved outcomes with more efficient use of resources, a common definition of quality care delivery.

Dr. Douglas reported financial relationships with Caption Health, Kowa, and Heartflow, which provided funding for the PRECISE trial. Dr. Indik reported no potential conflicts of interest. Dr. Blankstein reported financial relationships with Amgen, Caristo Diagnostics, and Novartis.

Douglas, MD, given in her presentation at the annual scientific sessions of the American Heart Association.

Unlike the highly complex diagnostic algorithms shunting suspected CAD patients to the vast array of potential evaluations, the newly tested protocol, characterized as a “precision strategy,” divides patients into those who are immediate candidates for invasive testing and those who are not. The discriminator is the PROMISE minimal risk assessment score, a tool already validated.

Those deemed candidates for testing on the basis of an elevated score undergo computed coronary CT angiography (cCTA). In those who are not, testing is deferred.
 

Strategy is simple but effective

Although simple, this pathway is highly effective, judging by the results of the PRECISE trial, which tested the strategy in 2,103 patients at 65 sites in North America and Europe. The primary outcome was a composite of major adverse cardiovascular events (MACE) that included death, nonfatal MI, and catheterization without observed CAD.

After a median follow-up of 11.8 months, the primary MACE endpoint was reached in about 11.3% of those in the usual-care group, which was more than twofold higher than the 4.2% in the precision strategy group. The unadjusted risk reduction was 65% but rose to more than 70% (hazard ratio, 0.29; P < .001) after adjustment for gender and baseline characteristics.

In the arm randomized to the precision strategy, 16% were characterized as low risk and received no further testing. Almost all the others underwent cCTA alone (48%) or cCTA with fractional flow reserve (FFR) (31%). Stress echocardiography, treadmill electrocardiography, and other functional studies were performed in the small proportion of remaining patients.
 

cCTA performed in just 15% of usual care

In the usual-care arm, cCTA with or without FFR was only performed in 15%. More than 80% of patients underwent evaluations with one or more of an array of functional tests. For example, one-third were evaluated with single photon emission CT/PET and nearly as many underwent stress echocardiography testing. Only 7% in usual care underwent no testing after referral.

Within the MACE composite endpoint, almost all the relative benefit in the precision strategy arm was derived from the endpoint of angiography performed without evidence of obstructive CAD (2.6% vs. 10.2%). Rates of all-cause mortality and MI were not significantly different.

Important for the safety and utility of the precision strategy, there “were no deaths or MI events among those assigned deferred testing ” in that experimental arm, according to Dr. Douglas, professor of research in cardiovascular diseases at Duke University, Durham, N.C.

Instead, those in the precision strategy arm were far less likely to undergo catheterization without finding CAD (20% vs. 60%) and far less likely to undergo catheterization without revascularization (28% vs. 70%).

In addition, the group randomized to the precision strategy were more likely to be placed on risk reducing therapies following testing. Although the higher proportion of patients placed on antihypertensive therapy did not reach statistical significance (P = .1), the increased proportions placed on lipid therapy (P < .001) and antiplatelet therapy (P < .001) did.

Citing a study in JAMA Cardiology that found that more than 25% of patients presenting with stable chest pain have normal coronary arteries, Dr. Douglas said that the precision strategy as shown in the PRECISE trial addresses several agreed-upon goals in guidelines from the AHA, the European Society of Cardiology and the U.K.’s National Institute for Health and Care Excellence. These goals include reducing unnecessary testing by risk stratification, improving diagnostic yield of the testing that is performed, and avoiding the costs and complications of unneeded invasive testing.

New protocol called preferred approach

On the basis of these results, Dr. Douglas called the precision strategy “a preferred approach in evaluating patients with stable symptoms and suspected coronary disease.”

Julie Indik, MD, PhD, a professor of medicine at the University of Arizona, Tuscon, said that application of this approach in routine care could have “a major impact on care” by avoiding unnecessary tests with no apparent adverse effect on outcomes.

Although not demonstrated in this study, Dr. Indik suggested that the large number of patients tested for CAD each year – she estimated 4 million visits – means that less testing is likely to have a major impact on the costs of care, and she praised “the practical, efficient” approach of the precision strategy.

Ron Blankstein, MD, director of cardiac computed tomography, Brigham and Women’s Hospital, Boston, also said these data “have both economic and safety implications.” As an AHA-invited discussant of this study, he emphasized that this is a strategy that should only be applied to lower risk patients with no prior history of CAD, but, in this group, he believes these data “will inform future guidelines.”

Dr. Douglas declined to speculate on whether the precision strategy will be incorporated into future guidelines, but she did say that the PRECISE data demonstrate that this approach improves quality of care.

In an interview, Dr. Douglas suggested that this care pathway could provide a basis on which to demonstrate improved outcomes with more efficient use of resources, a common definition of quality care delivery.

Dr. Douglas reported financial relationships with Caption Health, Kowa, and Heartflow, which provided funding for the PRECISE trial. Dr. Indik reported no potential conflicts of interest. Dr. Blankstein reported financial relationships with Amgen, Caristo Diagnostics, and Novartis.
