A University of South Florida Health (USF Health) preclinical study offers molecular insight into how activated protein C (APC) may improve aging patients’ tolerance to reperfusion injury — a potentially adverse effect of treatment for ischemic heart disease.
The research, published online Dec. 21 in Circulation Research, suggests that drugs derived from APC may limit ischemia and reperfusion-induced heart damage (reperfusion injury for short) and thereby help preserve cardiac function in older hearts.
Advanced age is a major risk factor for ischemic heart disease, often caused by a buildup of plaques in coronary arteries that narrows the vessels and restricts the supply of oxygenated blood to the heart. This “hardening of the arteries” can eventually trigger a heart attack.
