A federal investigation into the potential overuse of primary prevention implantable cardioverter defibrillators (ICDs) appears to have made hospitals more judicious in their use of the devices, according to a study published July 3 in the Journal of the American Medical Association.

The thinking behind the Seattle Proportional Risk Model goes like this: As the annual risk for all-cause mortality increases, the likelihood that the death will be sudden—or something an ICD could prevent—goes down.

Continuing cardiac resynchronization therapy (CRT) appeared to offer no benefit to patients who received a continuous flow left ventricular assist device (CF-LVAD), according to a multicenter study published in the Journal of the American Heart Association.

DALLAS, June 12, 2018 — The American Heart Association—the world’s leading voluntary organization dedicated to building healthier lives, free of cardiovascular diseases and stroke—announced today research grants totaling more than $28 million to the scientific teams that will create a new research network focused on understanding the causes of atrial fibrillation (AFib).

Patients who progressed to having longer episodes of subclinical atrial fibrillation (SCAF) were more than four times as likely to be hospitalized for heart failure in a one-year span, according to a study published June 4 in the Journal of the American College of Cardiology.

People who reported having stressful jobs were 48 percent more likely to develop atrial fibrillation (AFib), according to a Swedish study published in the European Journal of Preventive Cardiology.
