A small study of blood samples from 30 patients who had a heart attack within 44 days of blood sampling suggests a drop in the level of certain types of microRNA might signal impending trouble. "MicroRNAs act like a watchdog, and when their levels are reduced, heart disease takes a turn for the worse and heart attacks are likely to occur," said researcher Oxana Galenko, who presented the work at the American College of Cardiology Scientific Session.
