Researchers Report on the Efficacy of the Subcutaneous Implantable Cardioverter-Defibrillator
An FDA-mandated post-approval study of the subcutaneous cardioverter-defibrillator system in a real-world population revealed excellent safety and efficacy over five years.

Clinical Outcomes of Left Bundle Branch Area Pacing vs. Biventricular Pacing
Researchers compared biventricular pacing to left bundle branch area pacing (LBBAP) for cardiac resynchronization among patients living with heart failure caused by reduced left ventricular ejection fraction, along with either LBB block or need for ventricular pacing. The combined endpoint of all-cause mortality rates or heart failure hospitalizations was significantly lower with LBBAP.

Detecting Left Ventricular Thrombi
A study of early post-ST-elevation myocardial infarction patients who underwent echocardiographic testing and cardiac MRI showed echo misses about two-thirds of cardiac MRI-discovered left ventricular thrombi. However, an echo apical wall motion score can identify most patients in whom echo may miss thrombi for the selective use of cardiac MRI.

Rates of Ad Hoc PCI Remain Higher for Multivessel and Left Main Disease
In this retrospective analysis of patients from the New York state percutaneous coronary intervention (PCI) and coronary artery bypass grafting databases, ad hoc PCI was performed frequently among patients with left main and multivessel disease. Also, variability in ad hoc PCI use among hospitals and physicians for these populations was high.

Can Physical Activity Thwart the Negative Cardiometabolic Effects of Obesity?
Compared to normal-weight workers, overweight or obese employees in Spain exhibited a higher prevalence of risk factors for cardiovascular disease, which can be partially mitigated by regular exercise.

Alcohol: Double-Edged Sword, or Hatchet?
Researchers reported consuming two to 14 alcoholic drinks per week was associated with fewer major adverse cardiovascular events, which the authors noted could be explained in part by less stress-related neural activity demonstrated on PET and CT scans.

Cardiologists Consolidate, Update Guidance for Chronic Coronary Disease Management
Researchers incorporated shared decision-making, social determinants of health, and team-based care principles.

What Kind of Bundle Branch Block?
Assuming QRS widening in a supraventricular rhythm is not the result of hyperkalemia or other toxicity, and assuming the patient has not been diagnosed with Wolff-Parkinson-White syndrome, classification of 12-lead ECG conduction disturbances can be simplified into one of three basic categories. The tracing in the figure illustrates this concept.

Reconsidering Aspirin Therapy for Elderly Patients
A post-hoc analysis of the ASPREE trial revealed that in presumably healthy elderly subjects, taking low-dose aspirin daily over three years was associated with a significant drop in hemoglobin and ferritin levels vs. placebo, even when patients with major bleeding events were excluded.
