Medtronic has launched the pilot study of its extravascular implantable cardioverter defibrillator (EV ICD), which is designed to deliver defibrillation and antitachycardia pacing without transvenous leads.

Shorter reperfusion times for patients with ST-segment elevation myocardial infarction (STEMI) are associated with fewer cases of in-hospital heart failure and fewer readmissions for heart failure over the next 30 days, according to an observational study from Singapore published in Circulation: Cardiovascular Quality and Outcomes.

Adult congenital heart disease (ACHD)-related heart failure (HF) hospitalizations have increased in recent years and are associated with disproportionately higher costs, procedural burden and health resource use, according to new research published in the Journal of the American Heart Association.

Researchers from the Cleveland Clinic have developed what could become a new class of cardiovascular drugs—one that lowers platelet responsiveness and excessive clot formation by targeting a specific bacteria byproduct in the gut.

Instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) were equally safe in deferring patients from coronary revascularization, according to a pooled analysis of two randomized trials published Aug. 6 in JACC: Cardiovascular Interventions.

New research published in the Journal of the American Heart Association suggests light and moderate-to-vigorous physical activity, coupled with less sedentary time, is associated with more favorable levels of heart and vessel disease markers in older individuals.

A 13-gene signature can separate Kawasaki disease from other febrile and inflammatory conditions, potentially opening the door to blood tests that allow quicker treatment and the prevention of coronary artery aneurysms.

In a single-center study of smokers with heart failure, those who also had emphysema identified by CT were twice as likely to be rehospitalized for heart failure in the following two years.
