Even after adjusting for cardiovascular, behavioral and socioeconomic factors, black adults remain twice as likely to die from sudden cardiac death (SCD) as whites, suggests a study published in the Journal of the American College of Cardiology.

There were no serious adverse events related to competition in a study of 129 young athletes with implantable cardioverter defibrillators (ICDs), providing reassurance that moderate-to-intense physical activity in this population may be safer than previously thought.

Individuals with clinical depression could face a more than seven-fold increased risk of atrial fibrillation (AF), especially in the earliest stages of their diagnosis, a population study out of Denmark suggests.

A decades-long study of patients who have migraines with visual aura has linked the painful headaches to an increased risk of experiencing atrial fibrillation and, to a lesser degree, stroke, researchers report in the online edition of Neurology.

A miniature pacemaker developed for use in infants and those with limited vascular access has passed a proof-of-concept simulation and is entering its second phase of testing, researchers from Children’s National Health System in Washington, D.C., have reported.

Physicians who have financial relationships with biomedical manufacturers are up to 12 times more likely to use an implantable cardioverter-defibrillator (ICD) or cardiac resynchronization therapy-defibrillator (CRT-D) from that company instead of another manufacturer, according to preliminary research presented at the American Heart Association Scientific Sessions in Chicago.

When approached again, about a quarter of patients with atrial fibrillation (AFib) not taking anticoagulants due to physician-cited “patient refusal” said they would consider taking the drugs, according to preliminary research presented at the American Heart Association’s Scientific Sessions in Chicago.

For patients with nonvalvular atrial fibrillation (AFib), taking a direct oral anticoagulant (DOAC) instead of warfarin may cut the risk of dementia by 15 to 20 percent, according to a large database study published Nov. 2 in the Journal of the American Heart Association.

Mandatory CPR training in high school may contribute to higher rates of bystander intervention and improved survival following out-of-hospital cardiac arrest (OHCA), according to a registry study slated to be presented Nov. 11 at the American Heart Association’s Resuscitation Science Symposium in Chicago.

The American College of Cardiology, American Heart Association and Heart Rhythm Society on Nov. 6 released a new guideline for the evaluation and treatment of patients with bradycardia and cardiac conduction disorders.

A London, Kentucky, cardiologist was sentenced to 42 months in federal prison Oct. 31 after reportedly implanting “dozens” of unnecessary pacemakers and defrauding both his patients and their insurers, U.S. Attorney Robert M. Duncan, Jr., has announced.

A Stanford- and Apple-led atrial fibrillation study of more than 400,000 U.S. residents—the largest AFib screening effort to date—has entered its final phase of data collection, the company announced Nov. 1. The trial is expected to wrap up early next year.
