MedPage Today -- Coronary thrombi in patients who die suddenly are more likely to display signs of healing if they are caused by a plaque erosion rather than a rupture, researchers found. Among 111 victims of sudden coronary death examined at autopsy, 69% had plaques with more than day-old thrombi, according to a study by Renu Virmani, MD, president and medical director of the CVPath Institute in Gaithersburg, MD, and colleagues.
