Adjunctive pimavanserin brought clinically meaningful improvement in patients with anxious major depressive disorder inadequately responsive to standard antidepressants alone in a post hoc analysis of the CLARITY trial, Bryan Dirks, MD, reported at the virtual congress of the European College of Neuropsychopharmacology.

This is an intriguing observation, because it’s estimated that roughly 50% of individuals with major depressive disorder (MDD) have comorbid anxiety disorders or a high level of anxiety symptoms. Moreover, anxious depression has been associated with increased risk of suicidality, high unemployment, and impaired functioning.

CLARITY was a phase 2, multicenter, randomized, double-blind, placebo-controlled clinical trial whose positive results for the primary outcome have been published (J Clin Psychiatry. 2019 Sep 24;80[6]:19m12928. doi: 10.4088/JCP.19m12928). Because the encouraging findings regarding pimavanserin’s impact on anxious depression came from a post hoc analysis, the results need replication. That’s ongoing in a phase 3 trial of adjunctive pimavanserin versus placebo in patients with MDD, according to Dr. Dirks, director of clinical research at Acadia Pharmaceuticals, San Diego.

The CLARITY post hoc analysis included 104 patients with baseline MDD inadequately responsive to an SSRI or a serotonin norepinephrine reuptake inhibitor and anxious depression as defined by a Hamilton Depression Rating Scale (HAMD-17) anxiety/somatization factor subscale score of 7 or more. Twenty-nine of the patients were randomized to 34 mg of adjunctive oral pimavanserin once daily, and 75 to placebo. At 5 weeks, the HAMD-17 anxiety/somatization factor score in the pimavanserin group had dropped by a mean of 5 points from a baseline of 8.8, a significantly greater effect than the 2.8-point drop in placebo-treated controls.

By week 5, the treatment response rate as defined by at least a 50% reduction in HAMD-17 total score from baseline was 55% with pimavanserin and 22% with placebo. The remission rate as indicated by a HAMD-17 total score below 7 was 24% in the pimavanserin group, compared with 5% with placebo. These results translated into an effect size of 0.78, considered by statisticians to be on the border between medium and large. Those response and remission rates in patients with anxious depression were higher with pimavanserin and lower with placebo than in the overall CLARITY trial.

The impact of adjunctive pimavanserin on top of a background SSRI or SNRI was even more pronounced in the subgroup of patients with baseline severe MDD as defined by a HAMD-17 total score of 24 or more plus an anxiety/somatization factor score of 7 or greater. Seventeen such patients were randomized to adjunctive pimavanserin, 36 to placebo. At 5 weeks, the mean HAMD total score had dropped by 17.4 points from a baseline of 27.6 in the pimavanserin group, compared with a 9.3-point reduction in controls.

“Of note, significant differences from placebo were observed as early as week 2 with pimavanserin,” Dr. Dirks said.

Pimavanserin is a novel selective serotonin inverse agonist with a high affinity for 5-HT2A receptors and low affinity for 5-HT2C receptors. At present pimavanserin is Food Drug Administration–approved as Nuplazid only for treatment of hallucinations and delusions associated with Parkinson’s disease psychosis, but because of the drug’s unique mechanism of action it is under study for a variety of other mental disorders. Indeed, pimavanserin is now under FDA review for a possible expanded indication for treatment of dementia-related psychosis. The drug is also under study for schizophrenia as well as for MDD.

Percutaneous mitral valve repair with the MitraClip appears to be a safe, effective, and life-saving new treatment for severe acute mitral regurgitation (MR) secondary to MI in surgical noncandidates, even when accompanied by cardiogenic shock, according to data from the international IREMMI registry.

“Cardiogenic shock, when adequately supported, does not seem to influence short- and mid-term outcomes, so the development of cardiogenic shock should not preclude percutaneous mitral valve repair in this scenario,” Rodrigo Estevez-Loureiro, MD, PhD, said in presenting the IREMMI (International Registry of MitraClip in Acute Myocardial Infarction) findings reported at the Transcatheter Cardiovascular Research Therapeutics virtual annual meeting.

Commentators hailed the prospective IREMMI data as potentially practice changing in light of the dire prognosis of such patients when surgery is deemed unacceptably high risk because medical management, the traditionally the only alternative, has a 30-day mortality of up to 50%.

Severe acute MR occurs in an estimated 3% of acute MIs, and in roughly 10% of patients who present with acute MI complicated by cardiogenic shock (CS). The impact of intervening with the MitraClip in an effort to correct the acute MR arising from MI with CS has previously been addressed only in sparse case reports. The new IREMMI study is easily the largest dataset to date detailing clinical and echocardiographic outcomes, Dr. Estevez-Loureiro of Alvaro Cunqueiro Hospital in Vigo, Spain, said at the meeting, sponsored by the Cardiovascular Research Foundation.

He reported on 93 consecutive patients who underwent MitraClip implantation for acute MR arising in the setting of MI, including 50 patients in CS at the time of the procedure. All 93 patients had been turned down by their surgical team because of extreme surgical risk. Three-quarters of the MIs showed ST-segment elevation. Only six patients had a papillary muscle rupture; in the rest, the mechanism of acute MR involved left ventricular global remodeling associated with mitral valve leaflet tethering. Percutaneous valve repair was performed at 18 expert valvular heart centers in the United States, Canada, Israel, and five European countries.
 

Procedural success

Time from MI to MitraClip implantation averaged 24 days in the CS patients and 33 days in the comparator arm without CS.

“These patients had been turned down for surgery, so the attending physicians generally followed a strategy of trying to cool them down with mechanical circulatory support and vasopressors. MitraClip wasn’t an option at the beginning, but after two or three failed weanings from all the possible therapies, then MitraClip becomes an option. This is one of the reasons why the time lapse between MI and the clip is so large,” the cardiologist explained.

Procedural success rates were similar in the two groups: 90% in those with CS and 93% in those without. However, average procedure time was significantly longer in the CS patients: 143 minutes versus 83 minutes in the patients without CS.

At baseline, 86% of the CS group had grade 4+ MR, similar to the 79% rate in the non-CS patients. Postprocedurally, 60% of the CS group were MR grade 0/1 and 34% were grade 2, comparable to the rates of 65% and 23% in the non-CS group.

At 3 months’ follow-up, 83.4% of the CS group had MR grade 2 or less, again not significantly different from the 90.5% rate in non-CS patients. Systolic pulmonary artery pressure was also similar: 39.6 mm Hg in the CS patients, 44 mm Hg in those without. While everyone was New York Heart Association functional class IV preprocedurally, 79.5% of the CS group were NYHA class I or II at 3 months, not significantly different from the 86.5% prevalence in the comparator arm.
 

Longer-term clinical outcomes

At a median follow-up of 7 months, the composite primary clinical outcome composed of all-cause mortality or heart failure rehospitalization did not differ between the two groups: a 28% rate in the CS group and 25.6% in non-CS patients. All-cause mortality occurred in 16% with CS and 9.3% without, again not a significant difference.

In a Cox regression analysis, neither surgical risk score, patient age, left ventricular geometry, nor CS was independently associated with the primary composite endpoint. Indeed, the only independent predictor of freedom from mortality or heart failure readmission at follow-up was procedural success, which is very much a function of the experience of the heart team, Dr. Estevez-Loureiro continued.

Michael A. Borger, MD, PhD, who comoderated the late-breaking clinical science session, was wowed by the IREMMI results.

“The mortality rates, I can tell you, compared to traditional surgical series of acute MR in the face of ACS [acute cardiogenic shock] are very, very respectable,” commented Dr. Borger, director of the cardiac surgery clinic at the Leipzig (Ger.) University Heart Center.

“Extremely impressive,” agreed discussant Vinayak N. Bapat, MD, a cardiothoracic surgeon and valve scientist at the Minneapolis Heart Institute Foundation. He posed a practical question: “Should we take from this presentation that patients should be stabilized with something like ECMO [extracorporeal membrane oxygenation] or Impella [left ventricular assist device], then transferred to an expert center for the procedure?”

“I think that the stabilization is essential in the patients with cardiogenic shock,” Dr. Estevez-Loureiro replied. “Unlike with surgery, it’s very difficult to establish a MitraClip procedure in a couple of hours in the middle of the night. You have to stabilize them and then treat for shock with ECMO, Impella, or both. I think they should be transferred to a center than can deliver the best treatment. In centers with less experience, patients can be put on mechanical support and transferred to an expert valve center, not only for MitraClip implantation, but for discussion of all the treatment possibilities, including surgery.”

At a press conference in which Dr. Estevez-Loureiro presented highlights of the IREMMI study, discussant Dee Dee Wang, MD, said the international coinvestigators “need to be applauded” for this study.

“Having these outcomes is incredible,” declared Dr. Wang, a structural heart disease specialist at the Henry Ford Health System, Detroit.

While this is an observational study, it’s a high-quality dataset with excellent methodology. And conducting a randomized trial in patients with such high surgical risk scores – the CS group had an average EuroSCORE II of 21 – would be extremely difficult, according to the cardiologist.

Dr. Estevez-Loureiro reported receiving research grants from Abbott and serving as a consultant to that company as well as Boston Scientific.

Intravascular lithotripsy proved highly effective, safe, and user friendly as an adjunct to stenting for severely calcified coronary lesions at 30 days of follow-up in the pivotal Disrupt CAD III study aimed at gaining U.S. regulatory approval.

The technology is basically the same as in extracorporeal lithotripsy, used for the treatment of kidney stones for more than 30 years: namely, transmission of pulsed acoustic pressure waves in order to fracture calcium. For interventional cardiology purposes, however, the transmitter is located within a balloon angioplasty catheter, Dean J. Kereiakes, MD, explained in presenting the study results at the Transcatheter Cardiovascular Research Therapeutics virtual annual meeting.

In Disrupt CAD III, intravascular lithotripsy far exceeded the procedural success and 30-day freedom from major adverse cardiovascular event (MACE) performance targets set in conjunction with the Food and Drug Administration. In so doing, the intravascular lithotripsy device developed by Shockwave Medical successfully addressed one of the banes of contemporary interventional cardiology: heavily calcified coronary lesions.

Currently available technologies targeting such lesions, including noncompliant high-pressure balloons, intravascular lasers, cutting balloons, and orbital and rotational atherectomy, often yield suboptimal results, noted Dr. Kereiakes, medical director of the Christ Hospital Heart and Cardiovascular Center in Cincinnati.

Severe vascular calcifications are becoming more common, due in part to an aging population and the growing prevalence of hypertension, diabetes, and renal insufficiency. Severely calcified coronary lesions complicate percutaneous coronary intervention. They’re associated with increased risks of dissection, perforation, and periprocedural MI. Moreover, heavily calcified lesions impede stent delivery and expansion – and stent underexpansion is the leading predictor of restenosis and stent thrombosis, he observed at the meeting, sponsored by the Cardiovascular Research Foundation. Disrupt CAD III was a prospective single-arm study of 384 patients at 47 sites in the United States and several European countries. All participants had de novo coronary calcifications graded as severe by core laboratory assessment, with a mean calcified length of 47.9 mm by quantitative coronary angiography and a mean calcium angle and thickness of 292.5 degrees and 0.96 mm by optical coherence tomography.

“It’s staggering, the level of calcification these patients had. It’s jaw dropping,” Dr. Kereiakes observed.

Intravascular lithotripsy was used to prepare these severely calcified lesions for stenting. The intervention entailed transmission of acoustic waves circumferentially and transmurally at 1 pulse per second through tissue at an effective pressure of about 50 atm. Patients received an average of 69 pulses.

This was not a randomized trial; there was no sham-treated control arm. Instead, the comparator group selected under regulatory guidance was comprised of patients who had received orbital atherectomy for severe coronary calcifications in the earlier, similarly designed ORBIT II trial, which led to FDA marketing approval of that technology.

Key outcomes

The procedural success rate, defined as successful stent delivery with less than a 50% residual stenosis and no in-hospital MACE, was 92.4% in Disrupt CAD III, compared to 83.4% for orbital atherectomy in ORBIT II. The primary safety endpoint of freedom from cardiac death, MI, or target vessel revascularization at 30 days was achieved in 92.2% of patients in the intravascular lithotripsy trial, versus 84.4% in ORBIT II.

The 30-day MACE rate of 7.8% in Disrupt CAD III was primarily driven by periprocedural MIs, which occurred in 6.8% of participants. Only one-third of the MIs were clinically relevant by the Society for Coronary Angiography and Intervention definition. There were two cardiac deaths and three cases of stent thrombosis, all of which were associated with known predictors of the complication. There was 1 case each of dissection, abrupt closure, and perforation, but no instances of slow flow or no reflow at the procedure’s end. Transient lithotripsy-induced left ventricular capture occurred in 41% of patients, but they were benign events with no lasting consequences.

The device was able to cross and deliver acoustic pressure wave therapy to 98.2% of lesions. The mean diameter stenosis preprocedure was 65.1%, dropping to 37.2% post lithotripsy, with a final in-stent residual stenosis diameter of 11.9%, with a 1.7-mm acute gain. The average stent expansion at the site of maximum calcification was 102%, with a minimum stent area of 6.5 mm².

Optical coherence imaging revealed that 67% of treated lesions had circumferential and transmural fractures of both deep and superficial calcium post lithotripsy. Yet outcomes were the same regardless of whether fractures were evident on imaging.

At 30-day follow-up, 72.9% of patients had no angina, up from just 12.6% of participants pre-PCI. Follow-up will continue for 2 years.

Outcomes were similar for the first case done at each participating center and all cases thereafter.

“The ease of use was remarkable,” Dr. Kereiakes recalled. “The learning curve is virtually nonexistent.”
 

The reaction

At a press conference where Dr. Kereiakes presented the Disrupt CAD III results, discussant Allen Jeremias, MD, said he found the results compelling.

“The success rate is high, I think it’s relatively easy to use, as demonstrated, and I think the results are spectacular,” said Dr. Jeremias, director of interventional cardiology research and associate director of the cardiac catheterization laboratory at St. Francis Hospital in Roslyn, N.Y.

Intravascular lithotripsy proved highly effective, safe, and user friendly as an adjunct to stenting for severely calcified coronary lesions at 30 days of follow-up in the pivotal Disrupt CAD III study aimed at gaining U.S. regulatory approval.

The technology is basically the same as in extracorporeal lithotripsy, used for the treatment of kidney stones for more than 30 years: namely, transmission of pulsed acoustic pressure waves in order to fracture calcium. For interventional cardiology purposes, however, the transmitter is located within a balloon angioplasty catheter, Dean J. Kereiakes, MD, explained in presenting the study results at the Transcatheter Cardiovascular Research Therapeutics virtual annual meeting.

In Disrupt CAD III, intravascular lithotripsy far exceeded the procedural success and 30-day freedom from major adverse cardiovascular event (MACE) performance targets set in conjunction with the Food and Drug Administration. In so doing, the intravascular lithotripsy device developed by Shockwave Medical successfully addressed one of the banes of contemporary interventional cardiology: heavily calcified coronary lesions.

Currently available technologies targeting such lesions, including noncompliant high-pressure balloons, intravascular lasers, cutting balloons, and orbital and rotational atherectomy, often yield suboptimal results, noted Dr. Kereiakes, medical director of the Christ Hospital Heart and Cardiovascular Center in Cincinnati.

Severe vascular calcifications are becoming more common, due in part to an aging population and the growing prevalence of hypertension, diabetes, and renal insufficiency. Severely calcified coronary lesions complicate percutaneous coronary intervention. They’re associated with increased risks of dissection, perforation, and periprocedural MI. Moreover, heavily calcified lesions impede stent delivery and expansion – and stent underexpansion is the leading predictor of restenosis and stent thrombosis, he observed at the meeting, sponsored by the Cardiovascular Research Foundation. Disrupt CAD III was a prospective single-arm study of 384 patients at 47 sites in the United States and several European countries. All participants had de novo coronary calcifications graded as severe by core laboratory assessment, with a mean calcified length of 47.9 mm by quantitative coronary angiography and a mean calcium angle and thickness of 292.5 degrees and 0.96 mm by optical coherence tomography.

“It’s staggering, the level of calcification these patients had. It’s jaw dropping,” Dr. Kereiakes observed.

Ticagrelor monotherapy after just 3 months of dual-antiplatelet therapy (DAPT) in patients with ST-elevation myocardial infarction treated with drug-eluting stents proved a winning strategy in TICO-STEMI, a major randomized trial.

“This is the first report assessing the feasibility of ticagrelor monotherapy after short-term DAPT for STEMI patients with drug-eluting stents,” Byeong-Keuk Kim, MD, PhD, noted at the Transcatheter Cardiovascular Research Therapeutics virtual annual meeting.

The positive results were consistent with the earlier TWILIGHT study (Ticagrelor with Aspirin or Alone in High-Risk Patients after Coronary Intervention), which also showed clinical benefit at 1 year for 3 months of DAPT followed by ticagrelor (Brilinta) monotherapy, albeit only in PCI patients without an acute coronary syndrome (ACS) or with non-STEMI ACS (N Engl J Med. 2019 Nov 21;381[21]:2032-42).

TICO-STEMI was a prespecified substudy involving the 1,103 STEMI patients included in the previously reported parent 38-center South Korean TICO (Ticagrelor With or Without Aspirin in Acute Coronary Syndrome After PCI) study of 3,056 ACS patients treated with a second-generation ultrathin biodegradable polymer-coated sirolimus-eluting stent (JAMA. 2020 Jun 16;323[23]:2407-16).

The primary outcome in TICO-STEMI was the 12-month composite rate of net adverse clinical events, composed of major bleeding, all-cause mortality, acute MI, stroke, stent thrombosis, or target vessel revascularization. In an intention-to-treat analysis, the rate was 5.0% in the 12-month DAPT group and 3.7% with ticagrelor monotherapy after 3 months of DAPT, for a 27% relative risk reduction which didn’t achieve statistical significance. However, in an as-treated analysis, the between-group difference in the primary endpoint was stronger: a 5.2% incidence with 12 months of DAPT and 2.3% with ticagrelor monotherapy, for a relative risk reduction of 56%, which was statistically significant.

Major bleeding, one of two key secondary endpoints, was a different story: The incidence within 12 months by intention-to-treat was 2.9% with 12 months of DAPT compared to 0.9% with ticagrelor monotherapy, for a statistically significant 68% relative risk reduction in favor of ticagrelor monotherapy. In contrast, there was no between-group difference in the other secondary endpoint composed of major adverse cardio- and cerebrovascular events: 2.7% with ticagrelor monotherapy, 2.5% with 12 months of DAPT.

In the subgroup of TICO-STEMI patients at high bleeding risk, ticagrelor monotherapy was associated with a 12-month major bleeding rate of 1.8%, compared to 6.3% with a full year of DAPT. Conversely, in patients who underwent complex PCI, ticagrelor monotherapy was associated with a 4.9% rate of major adverse cardio- and cerebrovascular events through 1 year, numerically greater than but not statistically significantly different from the 2.7% rate with 12 months of DAPT.

Dr. Kim noted that the study had several limitations: It was open label, had no placebo control, and was underpowered to draw definite conclusions regarding the merits of dropping aspirin and continuing ticagrelor after 3 months in STEMI patients.

“Our findings should be interpreted with caution and call for confirmatory randomized trials,” he stressed.

Session comoderator Roxana Mehran, MD, said she “wholeheartedly” agrees with that assessment.

“We really do need a future trial, and we’re working to design TWILIGHT-STEMI,” a large randomized follow-up to the TWILIGHT trial, which she directed.

“I often imagine that we can have an even shorter duration of aspirin and ticagrelor and go to monotherapy sooner than 3 months in this very, very important subgroup,” added Dr. Mehran, professor of medicine, professor of population science and policy, and director of interventional cardiovascular research and clinical trials at the Icahn School of Medicine at Mount Sinai, New York.

Discussant Marco Valgimigli, MD, PhD, of University Hospital in Bern, Switzerland, calculated that the number-needed-to-treat with ticagrelor monotherapy rather than 12 months of DAPT in order to prevent one additional major bleeding event in TICO-STEMI participants at high bleeding risk was 22, as compared to an NNT of 77 in those without high bleeding risk.

One of the hottest topics now in psychiatry is the possibility of repurposing long-established cardiovascular medications for treatment of patients with serious mental illness, Livia De Picker, MD, PhD, said at the virtual congress of the European College of Neuropsychopharmacology.

The appeal is multifold. A huge unmet need exists in psychiatry for new and better treatments with novel mechanisms of action. Many guideline-recommended cardiovascular medications have a long track record, including a well-established safety profile with no surprises, and are available in generic versions. They can be developed for a new indication at minimal cost, noted Dr. De Picker, a psychiatrist at the University of Antwerp (Belgium).

The idea of psychiatric repurposing of drugs originally developed for nonpsychiatric indications is nothing new, she added. Examples include lithium for gout, valproate for epilepsy, and ketamine for anesthesiology.

One hitch in efforts to repurpose cardiovascular medications is that, when psychiatric patients have been included in randomized trials of the drugs’ cardiovascular effects, the psychiatric outcomes often went untallied.

Indeed, the only high-quality randomized trial evidence of psychiatric benefits for any class of cardiovascular medications is for statins, where a modest-sized meta-analysis of six placebo-controlled trials in 339 patients with schizophrenia showed the lipid-lowering agents had benefit for both positive and negative symptoms (Psychiatry Res. 2018 Apr;262:84-93). But that’s not a body of data of sufficient size to be definitive, in Dr. De Picker’s view.

Much of the recent enthusiasm for exploring the potential of cardiovascular drugs for psychiatric conditions comes from hypothesis-generating big data analyses drawn from Scandinavian national patient registries. Danish investigators scrutinized all 1.6 million Danes exposed to six classes of drugs of interest during 2005-2015 and determined that those on long-term statins, low-dose aspirin, ACE inhibitors, angiotensin receptor blockers, or allopurinol were associated with a decreased rate of new-onset depression, while high-dose aspirin and non-aspirin NSAIDs were associated with an increased rate, compared with a 30% random sample of the country’s population (Acta Psychiatr Scand. 2019 Jan;1391:68-77).

Similarly, the Danish group found that continued use of statins, angiotensin agents, or low-dose aspirin was associated with a decreased rate of new-onset bipolar disorder, while high-dose aspirin and other NSAIDs were linked to increased risk (Bipolar Disord. 2019 Aug;[15]:410-8). What these agents have in common, the investigators observed, is that they act on inflammation and potentially on the stress response system.

Meanwhile, Swedish investigators examined the course of 142,691 Swedes with a diagnosis of bipolar disorder, schizophrenia, or nonaffective psychosis during 2005-2016. They determined that, during periods when those individuals were on a statin, calcium channel blocker, or metformin, they had reduced rates of psychiatric hospitalization and self-harm (JAMA Psychiatry. 2019 Apr 1;76[4]:382-90).

Scottish researchers analyzed the health records of 144,066 patients placed on monotherapy for hypertension and determined that the lowest risk for hospitalization for a mood disorder during follow-up was in those prescribed an ACE inhibitor or angiotensin receptor blocker. The risk was significantly higher in patients on a beta-blocker or calcium channel blocker, and intermediate in those on a thiazide diuretic (Hypertension. 2016 Nov;68[5:1132-8).

“Obviously, this is all at a very macro scale and we have no idea whatsoever what this means for individual patients, number needed to treat, or which type of patients would benefit, but it does provide us with some guidance for future research,” according to Dr. De Picker.

In the meantime, while physicians await definitive evidence of any impact of cardiovascular drugs might have on psychiatric outcomes, abundant data exist underscoring what she called “shockingly high levels” of inadequate management of cardiovascular risk factors in patients with serious mental illness. That problem needs to be addressed, and Dr. De Picker offered her personal recommendations for doing so in a manner consistent with the evidence to date suggestive of potential mental health benefits of some cardiovascular medications.

She advised that, for treatment of hypertension in patients with bipolar disorder or major depression, an ACE inhibitor or angiotensin-converting enzyme inhibitor is preferred as first-line. There is some evidence to suggest lipophilic beta-blockers, which cross the blood-brain barrier, improve anxiety symptoms and panic attacks, and prevent memory consolidation in patients with posttraumatic stress disorder. But the Scottish data suggest that they may worsen mood disorders.

“I would be careful in using beta-blockers as first-line treatment for hypertension. They’re not in the guidelines for anxiety disorders. British guidelines recommend them to prevent memory consolidation in PTSD, but do not use them as first-line in patients with major depressive disorder or bipolar disorder,” she said. As for calcium channel blockers, the jury is still out, with mixed and inconsistent evidence to date as to the impact of this drug class on mental illness outcomes.

She recommended a very low threshold for prescribing statin therapy in patients with serious mental illness in light of the superb risk/benefit ratio for this drug class. She makes sure a statin is onboard in her patients with schizophrenia, major depressive disorder, or bipolar disorder who are over age 60. In her younger patients, she turns for guidance to an online calculator of an individual’s 10-year risk of a first acute MI or stroke.

Metformin has been shown to be beneficial for addressing the weight gain and other adverse metabolic effects caused by antipsychotic agents, and there is some preliminary evidence of improved psychiatric outcomes in patients with serious mental illness.

Christian Otte, MD, who also spoke at the session, noted that not only do emerging data point to the possibility that cardiovascular drugs might have benefit in terms of psychiatric outcomes, there is also some evidence, albeit mixed, that the converse is true: that is, psychiatric drugs may have cardiovascular benefits. He pointed to a South Korean trial in which 300 patients with a recent acute coronary syndrome and major depression were randomized to 24 weeks of escitalopram or placebo. At median 8.1 years of follow-up, the group that received the SSRI had a 31% relative risk reduction in the primary composite endpoint of all-cause mortality, acute MI, or percutaneous coronary intervention (JAMA. 2018 Jul 24; 320[4]:350–7).

“Potentially independent of their antidepressant effects, some SSRIs’ antiplatelet effects could be beneficial for patients with coronary heart disease, although the jury is still open regarding this question, with evidence in both directions,” said Dr. Otte, professor of psychiatry at Charite University Medical Center in Berlin.

Dr. De Picker offered an example as well: Finnish psychiatrists recently reported that cardiovascular mortality was reduced by an adjusted 38% during periods when 62,250 Finnish schizophrenia patients were on antipsychotic agents, compared with periods of nonuse of the drugs in a national study with a median 14.1 years of follow-up (World Psychiatry. 2020 Feb;19[1]:61-8).

“What they discovered – and this is quite contrary to what we are used to hearing about antipsychotic medication and cardiovascular risk – is that while the number of cardiovascular hospitalizations was not different in periods with or without antipsychotic use, the cardiovascular mortality was quite strikingly reduced when patients were on antipsychotic medication,” she said.

Asked by an audience member whether she personally prescribes metformin, Dr. De Picker replied: “Well, yes, why not? One of the very nice things about metformin is that it is actually a very safe drug, even in the hands of nonspecialists.

“I understand that maybe psychiatrists may not feel very comfortable in starting patients on metformin due to a lack of experience. But there are really only two things you need to take into account. About one-quarter of patients will experience GI side effects – nausea, vomiting, abdominal discomfort – and this can be reduced by gradually uptitrating the dose, dosing at mealtime, and using an extended-release formulation. And the second thing is that metformin can impair vitamin B₁₂ absorption, so I think, especially in psychiatric patients, it would be good to do an annual measurement of vitamin B₁₂ level and, if necessary, administer intramuscular supplements,” Dr. De Picker said.

She reported having no financial conflicts regarding her presentation.

One of the hottest topics now in psychiatry is the possibility of repurposing long-established cardiovascular medications for treatment of patients with serious mental illness, Livia De Picker, MD, PhD, said at the virtual congress of the European College of Neuropsychopharmacology.

The appeal is multifold. A huge unmet need exists in psychiatry for new and better treatments with novel mechanisms of action. Many guideline-recommended cardiovascular medications have a long track record, including a well-established safety profile with no surprises, and are available in generic versions. They can be developed for a new indication at minimal cost, noted Dr. De Picker, a psychiatrist at the University of Antwerp (Belgium).

The idea of psychiatric repurposing of drugs originally developed for nonpsychiatric indications is nothing new, she added. Examples include lithium for gout, valproate for epilepsy, and ketamine for anesthesiology.

One hitch in efforts to repurpose cardiovascular medications is that, when psychiatric patients have been included in randomized trials of the drugs’ cardiovascular effects, the psychiatric outcomes often went untallied.

Indeed, the only high-quality randomized trial evidence of psychiatric benefits for any class of cardiovascular medications is for statins, where a modest-sized meta-analysis of six placebo-controlled trials in 339 patients with schizophrenia showed the lipid-lowering agents had benefit for both positive and negative symptoms (Psychiatry Res. 2018 Apr;262:84-93). But that’s not a body of data of sufficient size to be definitive, in Dr. De Picker’s view.

Much of the recent enthusiasm for exploring the potential of cardiovascular drugs for psychiatric conditions comes from hypothesis-generating big data analyses drawn from Scandinavian national patient registries. Danish investigators scrutinized all 1.6 million Danes exposed to six classes of drugs of interest during 2005-2015 and determined that those on long-term statins, low-dose aspirin, ACE inhibitors, angiotensin receptor blockers, or allopurinol were associated with a decreased rate of new-onset depression, while high-dose aspirin and non-aspirin NSAIDs were associated with an increased rate, compared with a 30% random sample of the country’s population (Acta Psychiatr Scand. 2019 Jan;1391:68-77).

Similarly, the Danish group found that continued use of statins, angiotensin agents, or low-dose aspirin was associated with a decreased rate of new-onset bipolar disorder, while high-dose aspirin and other NSAIDs were linked to increased risk (Bipolar Disord. 2019 Aug;[15]:410-8). What these agents have in common, the investigators observed, is that they act on inflammation and potentially on the stress response system.

Meanwhile, Swedish investigators examined the course of 142,691 Swedes with a diagnosis of bipolar disorder, schizophrenia, or nonaffective psychosis during 2005-2016. They determined that, during periods when those individuals were on a statin, calcium channel blocker, or metformin, they had reduced rates of psychiatric hospitalization and self-harm (JAMA Psychiatry. 2019 Apr 1;76[4]:382-90).

Scottish researchers analyzed the health records of 144,066 patients placed on monotherapy for hypertension and determined that the lowest risk for hospitalization for a mood disorder during follow-up was in those prescribed an ACE inhibitor or angiotensin receptor blocker. The risk was significantly higher in patients on a beta-blocker or calcium channel blocker, and intermediate in those on a thiazide diuretic (Hypertension. 2016 Nov;68[5:1132-8).

“Obviously, this is all at a very macro scale and we have no idea whatsoever what this means for individual patients, number needed to treat, or which type of patients would benefit, but it does provide us with some guidance for future research,” according to Dr. De Picker.

In the meantime, while physicians await definitive evidence of any impact of cardiovascular drugs might have on psychiatric outcomes, abundant data exist underscoring what she called “shockingly high levels” of inadequate management of cardiovascular risk factors in patients with serious mental illness. That problem needs to be addressed, and Dr. De Picker offered her personal recommendations for doing so in a manner consistent with the evidence to date suggestive of potential mental health benefits of some cardiovascular medications.

She advised that, for treatment of hypertension in patients with bipolar disorder or major depression, an ACE inhibitor or angiotensin-converting enzyme inhibitor is preferred as first-line. There is some evidence to suggest lipophilic beta-blockers, which cross the blood-brain barrier, improve anxiety symptoms and panic attacks, and prevent memory consolidation in patients with posttraumatic stress disorder. But the Scottish data suggest that they may worsen mood disorders.

“I would be careful in using beta-blockers as first-line treatment for hypertension. They’re not in the guidelines for anxiety disorders. British guidelines recommend them to prevent memory consolidation in PTSD, but do not use them as first-line in patients with major depressive disorder or bipolar disorder,” she said. As for calcium channel blockers, the jury is still out, with mixed and inconsistent evidence to date as to the impact of this drug class on mental illness outcomes.

She recommended a very low threshold for prescribing statin therapy in patients with serious mental illness in light of the superb risk/benefit ratio for this drug class. She makes sure a statin is onboard in her patients with schizophrenia, major depressive disorder, or bipolar disorder who are over age 60. In her younger patients, she turns for guidance to an online calculator of an individual’s 10-year risk of a first acute MI or stroke.

Metformin has been shown to be beneficial for addressing the weight gain and other adverse metabolic effects caused by antipsychotic agents, and there is some preliminary evidence of improved psychiatric outcomes in patients with serious mental illness.

The absolute benefit of adding low-dose rivaroxaban to low-dose aspirin following revascularization for symptomatic lower-extremity peripheral artery disease (PAD) is significantly greater in patients with comorbid coronary artery disease (CAD), according to a new secondary analysis of the VOYAGER PAD trial.

“These findings suggest heterogeneity of prognostic risk for ischemic events in lower-extremity PAD patients, and may support shared decision-making with these patients,” William R. Hiatt, MD, observed in presenting the study results at the virtual annual congress of the European Society of Cardiology.

VOYAGER PAD was a 3-year, 34-country clinical trial in which 6,564 patients with symptomatic PAD who had recently undergone lower-limb revascularization were randomized in double-blind fashion to rivaroxaban (Xarelto) at 2.5 mg twice daily or placebo on top of background standard therapy with low-dose aspirin.

Among the 2,067 participants with baseline comorbid CAD, the primary outcome – a composite comprised of cardiovascular death, acute MI, ischemic stroke, acute limb ischemia, and major amputation – occurred in 18.9% of the rivaroxaban group at 3 years and 24.3% on placebo, for a highly significant 22% relative risk reduction.

In contrast, in the 4,497 patients with PAD only, the primary outcome occurred in 16.1% of those on rivaroxaban and 17.9% of controls, an 11% relative risk reduction which failed to reach statistical significance. The absolute risk reduction achieved with rivaroxaban was 5.4% in patients with PAD plus CAD versus 1.8% in those with PAD alone. Thus, the significant clinical benefit with rivaroxaban plus aspirin previously reported in the overall study population, with a number needed to treat for 3 years of 39 in order to prevent one primary outcome event, was largely driven by the superior outcomes in the dual-diagnosis subgroup, reported Dr. Hiatt, professor of medicine at the University of Colorado at Denver, Aurora.

“A strategy of rivaroxaban at 2.5 mg twice daily plus low-dose aspirin versus low-dose aspirin alone reduces ischemic events of the limb, brain, and heart, but also increases bleeding, with an overall net benefit,” the cardiologist said. “In particular, the benefits of this strategy for MI and ischemic stroke are robust, especially in patients with PAD and CAD.”

Indeed, the MI rate at 3 years in the dual diagnosis subgroup was 7.3% with rivaroxaban and 8.8% with placebo, for a 23% relative risk reduction, compared with rates of 3.3% and 3.7%, respectively, in patients with PAD only. Similarly, ischemic stroke occurred in 2.9% of patients with PAD and CAD in the rivaroxaban group, compared with 3.9% with placebo, whereas the rate in the PAD only group was identical at 2.6% regardless of whether patients were on rivaroxaban or placebo.

In patients without CAD, the clinical benefit of rivaroxaban was driven by reductions in severe limb events. Their rate of acute limb ischemia was 5.2% with rivaroxaban, compared with 8.3% with placebo, for a 37% relative risk reduction. In contrast, the reduction in acute limb ischemia with rivaroxaban in patients with PAD and CAD wasn’t significantly different from placebo.

Thrombolysis in Myocardial Infarction major bleeding occurred in 2.4% of patients with PAD and CAD on rivaroxaban, compared with 1.1% on placebo, and in 1.7% and 1.5% of patients with PAD alone. Of note, rates of ischemic stroke or fatal hemorrhage were low and similar at less than 1% in all four groups, Dr. Hiatt noted.

VOYAGER PAD was sponsored by Bayer and Janssen. Dr. Hiatt reported receiving research grant support from those two companies as well as Amgen.

Depression or an anxiety disorder in male adolescents was associated with a 20% increased likelihood of experiencing an acute MI in midlife in a Swedish national registry study presented at the virtual annual congress of the European Society of Cardiology.

The association was mediated in part by poor stress resilience and lack of physical fitness among these teenagers with an affective disorder, reported Cecilia Bergh, PhD, of Obrero (Sweden) University.

Her study was made possible by Sweden’s comprehensive national health care registries coupled with the Nordic nation’s compulsory conscription for military service. The mandatory conscription evaluation during the study years included a semistructured interview with a psychologist to assess stress resilience through questions about coping with everyday life, a medical history and physical examination, and a cardiovascular fitness test using a bicycle ergometer.

The study included 238,013 males born in 1952-1956. They were aged 18-19 years when they underwent their conscription examination, at which time 34,503 of them either received or already had a diagnosis of depression or anxiety. During follow-up from 1987 to 2010, a first acute MI occurred in 5,891 of the men. The risk was increased 51% among those with an earlier teen diagnosis of depression or anxiety.

In a Cox regression analysis adjusted for levels of adolescent cardiovascular risk factors, including blood pressure, body mass index, and systemic inflammation, as well as additional potential confounders, such as cognitive function, parental socioeconomic index, and a summary disease score, the midlife MI risk associated with adolescent depression or anxiety was attenuated, but still significant, with a 24% increase. Upon further statistical adjustment incorporating adolescent stress resilience and cardiovascular fitness, the increased risk of acute MI in midlife associated with adolescent depression or anxiety was further attenuated yet remained significant, at 18%.

Dr. Bergh shared her thoughts on preventing this increased risk of acute MI at a relatively young age: “Effective prevention might focus on behavior, lifestyle, and psychosocial stress in early life. If a healthy lifestyle is encouraged as early as possible in childhood and adolescence, it is more likely to persist into adulthood and to improve longterm health. So look for signs of stress, depression, or anxiety that is beyond normal teenager behavior and a persistent problem. Teenagers with poor well-being could benefit from additional support to encourage exercise and also to develop strategies to deal with stress.”

She reported having no financial conflicts regarding her study, conducted free of commercial support.

In a Cox regression analysis adjusted for levels of adolescent cardiovascular risk factors, including blood pressure, body mass index, and systemic inflammation, as well as additional potential confounders, such as cognitive function, parental socioeconomic index, and a summary disease score, the midlife MI risk associated with adolescent depression or anxiety was attenuated, but still significant, with a 24% increase. Upon further statistical adjustment incorporating adolescent stress resilience and cardiovascular fitness, the increased risk of acute MI in midlife associated with adolescent depression or anxiety was further attenuated yet remained significant, at 18%.

Dr. Bergh shared her thoughts on preventing this increased risk of acute MI at a relatively young age: “Effective prevention might focus on behavior, lifestyle, and psychosocial stress in early life. If a healthy lifestyle is encouraged as early as possible in childhood and adolescence, it is more likely to persist into adulthood and to improve longterm health. So look for signs of stress, depression, or anxiety that is beyond normal teenager behavior and a persistent problem. Teenagers with poor well-being could benefit from additional support to encourage exercise and also to develop strategies to deal with stress.”

Depression or an anxiety disorder in male adolescents was associated with a 20% increased likelihood of experiencing an acute MI in midlife in a Swedish national registry study presented at the virtual annual congress of the European Society of Cardiology.

The association was mediated in part by poor stress resilience and lack of physical fitness among these teenagers with an affective disorder, reported Cecilia Bergh, PhD, of Obrero (Sweden) University.

Her study was made possible by Sweden’s comprehensive national health care registries coupled with the Nordic nation’s compulsory conscription for military service. The mandatory conscription evaluation during the study years included a semistructured interview with a psychologist to assess stress resilience through questions about coping with everyday life, a medical history and physical examination, and a cardiovascular fitness test using a bicycle ergometer.

The study included 238,013 males born in 1952-1956. They were aged 18-19 years when they underwent their conscription examination, at which time 34,503 of them either received or already had a diagnosis of depression or anxiety. During follow-up from 1987 to 2010, a first acute MI occurred in 5,891 of the men. The risk was increased 51% among those with an earlier teen diagnosis of depression or anxiety.

Spain and China used very different public health responses to the COVID-19 crisis, and that has had significant consequences in terms of the mental health as well as physical health of the two countries’ citizens, Roger Ho, MD, reported at the virtual congress of the European College of Neuropsychopharmacology.
 

Dr. Ho, a psychiatrist at the National University of Singapore, presented a first-of-its-kind cross-cultural comparative study of the impact of the COVID-19 pandemic in two epicenters on opposite sides of the world. A total of 1,539 participants drawn from the general populations in the two countries completed the online National University of Singapore COVID-19 Questionnaire. The survey was conducted in late February/early March in China and in mid-April in Spain, times of intense disease activity in the countries.

The questionnaire assesses knowledge and concerns about COVID, precautionary measures taken in the last 14 days, contact history, and physical symptoms related to COVID in the last 14 days. The pandemic’s psychological impact was evaluated using the Impact of Event Scale–Revised (IES-R). Participants also completed the Depression, Anxiety, and Stress-21 Scale (DASS-21).

Of note, the pandemic has taken a vastly greater physical toll in Spain than China. As of May 5, there were 83,000 confirmed cases of COVID-19 in China, with a population of 1.39 billion, compared with 248,000 in Spain, with a population of 46.9 million. The Spanish case rate of 5,500 per 1 million population was 100 times greater than China’s; the Spanish mortality rate of 585 per million was 185-fold greater.
 

Mental health findings

Spaniards experienced significantly higher levels of stress and depression as reflected in DASS-21 subscale scores of 14.22 and 8.65, respectively, compared with 7.86 and 6.38, in Chinese respondents. Spanish subjects also reported greater anxiety levels than the Chinese on the DASS-21 anxiety subscale, although not to a statistically significant extent. Yet, counterintuitively, given the DASS-21 results, the pandemic had a greater adverse psychological impact on the Chinese subjects as reflected in their significantly higher average IES-D score of 30.76 versus 27.64 in Spain. Dr. Ho offered a hypothesis as to why: The survey documented that many Chinese respondents felt socially stigmatized, and that their nation had been discriminated against by the rest of the world because the pandemic started in China.

Satisfaction with the public health response

Spanish respondents reported less confidence in their COVID-related medical services.

“This could be due to the rising number of infected health care workers in Spain. In contrast, the Chinese had more confidence in their medical services, probably because the government quickly deployed medical personnel and treated COVID-19 patients at rapidly built hospitals,” according to Dr. Ho.

Spain and other European countries shared four shortcomings in their pandemic response, he continued: lack of personal protective equipment for health care workers, delay in developing response strategies, a shortage of hospital beds, and inability to protect vulnerable elderly individuals from infection in nursing homes.

Experiencing cough, shortness of breath, myalgia, or other physical symptoms potentially associated with COVID-19 within the past 14 days was associated with worse depression, anxiety, and stress scores in both China and Spain. This underscores from a mental health standpoint the importance of rapid and accurate testing for the infection, Dr. Ho said.

Significantly more Spanish respondents felt there was too much unnecessary worry about COVID-19, suggesting a need for better health education regarding the pandemic.
 

Use of face masks

Consistent use of face masks regardless of the presence or absence of symptoms was far more common in the Chinese epicenter, where, unlike in Spain, this precautionary measure was associated with significantly lower IES-R and DASS-21 scores.

“One of the important findings in our study is that wearing a face mask seems to protect the mental health in China, but for the Spanish, wearing a face mask was associated with higher IES-R scores,” Dr. Ho said. “We understand that it is difficult for Europeans to accept the need to use masks for healthy people because mask-wearing suggests vulnerability to sickness and concealment of identity. The Chinese have a collective culture. They believe they should wear a face mask to protect their health and that of other people.”

Dr. Ho reported no financial conflicts regarding his study, conducted with coinvestigators at Huaibei (China) Normal University and Complutense University of Madrid.

Listening to Mozart’s piano music improves epilepsy, according to a meta-analysis presented at the virtual congress of the European College of Neuropsychopharmacology.

The results of the meta-analysis of 12 published studies of the so-called Mozart Effect that met rigorous Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines demonstrate that listening to Mozart results in significant reductions in both epileptic seizure frequency and interictal epileptiform discharges (IED), compared with baseline.

The benefits were apparent during and after even a single listening session, although the effect was greater with regular daily listening sessions, according to Gianluca Sesso, MD, a resident in child and adolescent psychiatry at the University of Pisa (Italy.)

“Obviously other music may have similar effects, but it may be that Mozart’s sonatas have distinctive rhythmic structures which are particularly suited to working on epilepsy,” he speculated, adding that the mechanism involved in the Mozart Effect on brain systems remains unclear.

“The highly consistent results of our meta-analysis strongly suggest that music-based neurostimulation may improve the clinical outcome in epilepsy by reducing seizures and IED, and thus deserves to be included in the set of nonpharmacologic complementary approaches for treating epilepsy,” Dr. Sesso added.

Four studies examined the effects of listening to Mozart’s Sonata for Two Pianos in D, K.448, the most-studied piece of music as a treatment for epilepsy. The data documented a 31% reduction in seizure frequency and 28% decrease in IED during a single listen, and a 79% reduction in IED after long-term Mozart music therapy. Similarly, studies demonstrated that listening to a set of Mozart’s compositions resulted in a 36% reduction in IED during and 38% decrease after a single listen, while regular listening in a prolonged treatment period resulted in a 66% reduction in seizure frequency from baseline.

Several studies compared the benefits of listening to K. 488 with those accrued through listening to Piano Sonata No. 16 in C major, K. 545. There was no significant difference between the two, according to Dr. Sesso.

He reported having no financial conflicts regarding his meta-analysis, carried out free of commercial support.

The full details of the meta-analysis were recently published in Clinical Neurophysiology.

Objective neuropsychological tests can be used to subclassify the cognitive symptoms present in patients with major depression into three patterns having implications for treatment responsiveness, Gitte Moos Knudsen, MD, reported at the virtual congress of the European College of Neuropsychopharmacology.

“Our data highlight the importance of assessing and targeting cognitive symptoms,” said Dr. Knudsen, the ECNP president and professor of neurology at the University of Copenhagen.

She was a coauthor of the Danish NeuroPharm study, in which 92 antidepressant-free patients with moderate or severe major depressive disorder and 103 healthy controls completed a comprehensive neuropsychological test battery. The testing included a validation study of the EMOTICOM test battery, a novel neuropsychological test battery developed specifically to assess what has been called “hot” cognition, such as emotion processing, social cognition, and affective verbal memory.

Overall, the depressed patients collectively showed moderate increases in measures of guilt and shame, moderate deficits in working and verbal memory, moderately slowed reaction time, and mild to moderate negative affective bias, compared with controls. No correlation was found between performance on any of the individual cognitive domains and depression severity as measured using the Hamilton Depression Rating Scale, underscoring the concept that cognitive impairment is a distinct component of depressive pathology rather than an extension of the classic mood and somatic symptoms of major depression.

Cluster analysis revealed three distinct patterns of cognitive impairment in the study population. Unlike the individual cognitive domains, these cognitive clusters did correlate with depression severity. The implication is that neuropsychological testing may identify large subgroups of patients with major depression who may benefit from augmentation of antidepressant medication with treatments targeting impaired cognition, as they become available.

Investigators classified 38 of the 92 patients with major depressive disorder as falling within Cluster A. That is, they exhibited marked deficits in hot cognition expressed in a greatly impaired ability to accurately identify facial emotions on photographs, with resultant high scores for emotion recognition bias and emotion misattribution bias. This impairment in hot cognition was accompanied by minimal guilt and shame and little or no deficits in the cold cognitive domains of verbal and working memory.

Cluster B, composed of 28 patients, was characterized by generally good cognitive function, with positive biases in emotion processing, near-normal guilt and shame ratings, but moderate deficits across the cold cognition domains, making for a mirror image of Cluster A.

The 26 patients in Cluster C demonstrated large deficits in both the hot and cold cognition domains, with particularly pronounced guilt and shame scores.

The three clusters didn’t differ in terms of age or sex. However, patients in Cluster C had significantly more severe core depressive symptoms as measured by Hamilton scores than in Clusters A and B.

This analysis from the NeuroPharm study was cross-sectional. Dr. Knudsen cited a recent large Chinese longitudinal study to underscore how the prevalence of patient-reported cognitive deficits in major depressive disorder is high. And while those deficits decrease over time, they nonetheless remain substantial after 6 months on antidepressant therapy.

That study included 598 Chinese outpatients with major depressive disorder. At baseline, 77% had cognitive symptoms as evidenced by a total score of 21 or more on the self-rated Perceived Deficits Questionnaire–Depression (PDQ-D). One month after going on antidepressant monotherapy, the prevalence of cognitive symptoms had dropped to 59%. At 2 months, the rate was 45%. And at month 6, a PDQ-D score of 21 or greater was still present in 32.4% of patients. High baseline PDQ-D scores were associated with worse clinical outcomes, including a lower treatment response rate at 1 month and a lower remission rate at 2 months. Moreover, high PDQ-D scores at 2 months were associated with lower remission and higher relapse rates at 6 months.

Dr. Knudsen reported having no financial conflicts regarding the NeuroPharm study, which was conducted free of commercial support. She serves as an adviser to Sage Therapeutics and Sanos.

And at month 6, a PDQ-D score of 21 or greater was still present in 32.4% of patients. High baseline PDQ-D scores were associated with worse clinical outcomes, including a lower treatment response rate at 1 month and a lower remission rate at 2 months. Moreover, high PDQ-D scores at 2 months were associated with lower remission and higher relapse rates at 6 months.
