A 15-year review of myocardial injury events in a Minnesota community in the Journal of the American College of Cardiology found that non-atherosclerotic causes are more common in younger women than men. Spontaneous coronary artery dissection was found in 11% of heart attacks among women ages 65 and younger, but only in 0.7% of men. "This research shines a spotlight on heart attack causes that have historically been underrecognized, particularly in women," co-author Claire Raphael said.

Bacterial infections, particularly from viridans group streptococci that are found in the mouth, may contribute to heart attacks by causing inflammation in arterial plaque, according to a study in the Journal of the American Heart Association. "We've long suspected that inflammation is a key driver of cholesterol plaque formation and plaque rupture leading to heart attacks," said Dr. Sergiu Darabant of Miami Cardiac & Vascular Institute. "This study adds another piece to the puzzle -- showing how bacteria from the mouth might play a hidden role in driving coronary inflammation."

Research presented at the European Society of Cardiology Congress highlights the cardiovascular benefits of vaccines against influenza, respiratory syncytial virus and herpes zoster.
