Top stories in cardiology: Cognitive decline accelerates after congenital heart disease events, longer working hours may increase stroke risk

Among the top stories in cardiology last week were a study that found there was an accelerated rate of cognitive decline after congenital heart disease events and a study that suggested working more than 10 hours per day may lead to elevated risk for stroke.

Other highlights included findings that determined cardiac resynchronization therapy defibrillator implantation conferred improved outcomes compared with implantable cardioverter defibrillator implantation in patients without left bundle branch block, a study that concluded vitamin D supplementation did not reduce major adverse CV events and a study that suggested statins reduced stroke risk after radiation for cancer.

Rate of cognitive decline accelerates after congenital heart disease events

Among adults diagnosed with congenital heart disease, there was an accelerated rate of cognitive decline after the event, according to findings published in the Journal of the American College of Cardiology. Read more.

Longer working hours may increase stroke odds

Working more than 10 hours per day may lead to elevated risk for stroke, according to findings published in Stroke. Read more.

Cardiac resynchronization therapy defibrillator confers improved outcomes for nonspecific intraventricular conduction delay

Cardiac resynchronization therapy defibrillator implantation conferred improved outcomes vs. implantable cardioverter defibrillator implantation in patients without left bundle branch block, particularly in those with nonspecific intraventricular conduction delay who had a QRS duration of at least 150 milliseconds, according to a study published in the Journal of the American College of Cardiology.

Vitamin D supplementation fails to reduce major adverse CV events

Vitamin D supplementation did not reduce individual CVD endpoints, all-cause mortality or major adverse CV events, according to a meta-analysis published in JAMA Cardiology. Read more.

Statins reduce stroke risk after radiation for cancer

Patients with cancer who took statins after undergoing radiotherapy to the head, neck and thorax had a significant reduction in stroke, according to a study published in the Journal of the American Heart Association. Read more.
