Mechanical Circulatory Support in Patients With COVID-19 Presenting With Myocardial Infarction.

ST-segment elevation myocardial infarction (STEMI) complicating COVID-19 is associated with an increased risk of cardiogenic shock and mortality. However, little is known about the frequency of use and clinical impact of mechanical circulatory support (MCS) in these patients. We sought to define patterns of MCS utilization, patient characteristics, and outcomes in patients with COVID-19 with STEMI.

The Placebo Effect on Symptoms, Quality of Life, and Functional Outcomes in Patients With Angina Pectoris: A Meta-analysis of Randomized Placebo-Controlled Trials.

Background: The placebo effect is a well described phenomenon in blinded studies evaluating antianginal therapeutics, although its effect on clinical research metrics remains unknown. We conducted a systematic review and meta-analysis to quantify the effect of placebo on end points of symptoms, life quality, and functional outcomes in randomized placebo-controlled trials (RCTs) of symptomatic stable coronary artery disease.

Methods: We systematically reviewed MEDLINE, EMBASE, and the Cochrane database for double-blind RCTs of antiangina therapeutics.

Effect of Transaortic Valve Intervention for Aortic Stenosis on Myocardial Mechanics.

Chronic afterload excess in aortic stenosis results in compensatory concentric hypertrophy which mitigates the increased systolic load. Surgical aortic valve replacement has been shown to decrease afterload and improve left ventricular (LV) ejection fraction (EF). The extent to which these changes take place in patients undergoing TAVI (transcatheter aortic valve intervention) may be different than what has been observed in the surgical aortic valve replacement patients who were generally younger with few co-morbidities.

Impact of COVID-19 pandemic on STEMI care: An expanded analysis from the United States.

Objective: To evaluate the impact of COVID-19 pandemic migitation measures on of ST-elevation myocardial infarction (STEMI) care.

Background: We previously reported a 38% decline in cardiac catheterization activations during the early phase of the COVID-19 pandemic mitigation measures. This study extends our early observations using a larger sample of STEMI programs representative of different US regions with the inclusion of more contemporary data.

Adding Increased Energy or Activity to Criterion (A) of the DSM-5 Definition of Hypomania and Mania: Effect on the Diagnoses of 907 Patients From the Bipolar Collaborative Network.

Objective: According to DSM-IV, criterion (A) for diagnosing a hypomanic/manic episode is mood change (ie, elevated, expansive, or irritable mood). Criterion (A) was redefined in DSM-5, adding increased energy or activity in addition to mood change. We sought to investigate the effect of adding increased energy or activity to criterion (A) for the diagnosis of hypomania/mania and, thus, bipolar disorder.

Interruption of Dual Antiplatelet Therapy Within Six Months After Coronary Stents (from the Dual Antiplatelet Therapy Study).

The risk of major adverse cardiac and cerebrovascular events (MACCE) in subjects who interrupt temporarily or permanently thienopyridine therapy in the first 6 months after percutaneous coronary intervention (PCI) remains uncertain. In the dual antiplatelet therapy (DAPT) study subjects were enrolled within 72 hours of PCI and treated with aspirin and a thienopyridine for 12 months before being randomized to continued thienopyridine versus placebo. This analysis focuses on the 12-month period before randomization.

Heart failure hospitalization reduction and cost savings achieved by improved delivery of effective biventricular pacing: economic implications of the OLE study under the US setting.

The hOLter for Efficacy analysis (OLE) study demonstrated that current device pacing diagnostics overestimate the amount of cardiac resynchronization therapy (CRT) pacing that effectively stimulates the cardiac tissue. Sub-optimal pacing increases mortality, hospitalizations, and associated health-care costs. We sought to estimate the expected number of hospital admissions due to heart failure (HF) and its respective financial impact in patients with maximized effective pacing versus conventional pacing.

Efficacy and Safety of Deep Transcranial Magnetic Stimulation for Obsessive-Compulsive Disorder: A Prospective Multicenter Randomized Double-Blind Placebo-Controlled Trial.

Objective: Obsessive-compulsive disorder (OCD) is a chronic and disabling condition that often responds unsatisfactorily to pharmacological and psychological treatments. Converging evidence suggests a dysfunction of the cortical-striatal-thalamic-cortical circuit in OCD, and a previous feasibility study indicated beneficial effects of deep transcranial magnetic stimulation (dTMS) targeting the medial prefrontal cortex and the anterior cingulate cortex. The authors examined the therapeutic effect of dTMS in a multicenter double-blind sham-controlled study.

The Past, Present and Future of Cardiac Resynchronization Therapy.

Cardiac resynchronization therapy (CRT) has revolutionized the care of the patients with heart failure with reduced ejection fraction and electrical dyssynchrony. The current guidelines for patient selection include measurement of left ventricular systolic function, QRS duration and morphology, and functional classification. Despite consistent and increasing evidence supporting CRT use in appropriate patients, CRT has been underutilized.

Duration of Dual Antiplatelet Therapy in Patients with CKD and Drug-Eluting Stents: A Meta-Analysis.

Background And Objectives: Whether prolonged dual antiplatelet therapy (DAPT) is more protective in patients with CKD and drug-eluting stents compared with shorter DAPT is uncertain. The purpose of this meta-analysis was to examine whether shorter DAPT in patients with drug-eluting stents and CKD is associated with lower mortality or major adverse cardiovascular event rates compared with longer DAPT.

Design, Setting, Participants, & Measurements: A Medline literature research was conducted to identify randomized trials in patients with drug-eluting stents comparing different DAPT duration strategies.

Changes in mechanical dyssynchrony in severe aortic stenosis patients undergoing transcatheter aortic valve replacement.

Introduction: Aortic stenosis (AS) imposes a significant afterload on the left ventricle, but regional manifestations of the overall load may not be uniform, leading to mechanical dyssynchrony. Accordingly, we evaluated the prevalence of dyssynchrony in patients with severe AS at baseline as well as changes after transfemoral aortic valve replacement (TAVR).

Methods: This study is a retrospective analysis of 225 patients in sinus rhythm who underwent TAVR for severe AS, in whom inter-ventricular and intra-ventricular dyssynchrony were measured at baseline, discharge, 1 month, and 1 year.

Benefit and Risk of Prolonged DAPT After Coronary Stenting in Women.

Background: Women may derive differential benefit from prolonged DAPT (dual antiplatelet therapy) after coronary stenting than men. We assessed whether the risks/benefits of prolonged DAPT differ between women and men.

Methods And Results: The DAPT study was a randomized double-blind, placebo-controlled trial comparing continued thienopyridine versus placebo beyond 12 months after coronary stenting.

Usefulness of Serial 12-Lead Electrocardiograms in Predicting 30-Day Outcomes in Patients With Undifferentiated Chest Pain (the ASAP CATH Study).

An initial electrocardiogram (ECG) and serial troponin measurements are both independently and incrementally predictive of acute coronary syndrome in patients presenting with undifferentiated chest pain in the Emergency Department (ED). However, it is unclear if serial (ECGs) add significant to the contemporary diagnostic evaluation of this patient group. The ASAP CATH study was a single center, prospective study that enrolled patients presenting to an ED with undifferentiated chest pain.

Effects of Lisdexamfetamine Dimesylate on Functional Impairment Measured on the Sheehan Disability Scale in Adults With Moderate-to-severe Binge Eating Disorder: Results from Two Randomized, Placebo-controlled Trials.

In two Phase III, randomized, placebo-controlled trials (NCT01718483 and NCT01718509 at ClinicalTrials.gov), lisdexamfetamine dimesylate (LDX) reduced binge eating days/week in adults with moderate-to-severe binge eating disorder (BED). We describe the effects of LDX (50mg and 70mg) on the Sheehan Disability Scale (SDS; exploratory endpoint) from both studies.

Combination Phentermine-Topiramate Extended Release for the Treatment of Binge Eating Disorder: An Open-Label, Prospective Study.

The goal of this study was to obtain preliminary data on the usefulness of the combination of phentermine and topiramate extended release (phentermine-topiramate) in binge-eating disorder (BED) associated with obesity or overweight. Ten participants with BED and obesity or overweightness with at least one weight-related complication received phentermine-topiramate in an open-label, prospective, 12-week trial. The primary outcome measure was change in weight.

Subadventitial stenting around occluded stents: A bailout technique to recanalize in-stent chronic total occlusions.

Objectives: To evaluate the outcomes of subadventitial stenting (SS) around occluded stents for recanalizing in-stent chronic total occlusions (IS-CTOs).

Background: There is little evidence on the outcomes of SS for IS-CTO.

Methods: We examined the outcomes of SS for IS-CTO PCI at 14 centers between July 2011 and June 2017, and compared them to historical controls recanalized using within-stent stenting (WSS).

Lesion Complexity and Outcomes of Extended Dual Antiplatelet Therapy After Percutaneous Coronary Intervention.

Background: Subjects undergoing coronary stenting with complex lesion anatomy may experience different risks and benefits with prolonged dual antiplatelet therapy.

Objectives: The authors assessed the effect of 30 months versus 12 months of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) based on the presence or absence of anatomically-complex target lesions.

Methods: In the DAPT Study, combined myocardial infarction (MI) or stent thrombosis and moderate/severe bleeding were assessed in enrolled (n = 25,416) and randomized (n = 11,554) subjects.
