The study, published in Circulation Research, identifies cardiac fibroblasts and resident macrophages as essential contributors to the characteristic electrical activity that maintains this arrhythmia

A prespecified landmark analysis of the REBOOT trial, published in The European Heart Journal Cardiovascular Pharmacotherapy, shows no clinical benefit of beta-blockers during the first year after infarction or beyond one year, in patients without reduced ejection fraction.

A team from the CNIC and Hospital Clínico Universitario de Valladolid has developed a minimally invasive, catheter-based procedure to treat defective mechanical aortic valves

A CNIC research team has identified for the first time the biological mechanism underlying this susceptibility: high blood pressure creates a hidden metabolic vulnerability in the heart that becomes destabilized when anthracyclines are administered.

A CNIC study reveals that neutrophils—a type of immune cell—are less aggressive at night, explaining why nighttime heart attacks are less severe than those occurring during the day

The study, published in The New England Journal of Medicine, shows that beta-blockers do not reduce mortality, recurrent infarction, or heart failure in post-infarction patients with normal cardiac function
