COLchicine to Prevent Sympathetic Denervation After an Acute Myocardial Infarction
کلید واژه ها

شرح
COLD-MI study aims to explore colchicine's impact on myocardial denervation following reperfused acute myocardial infarction. Acute myocardial infarction is the leading cause of heart failure (HF). It induces myocardial denervation predisposing to ventricular rhythm disorders and death. This denervation linked to infarction's size occurs by direct ischaemic mechanisms during the initial coronary occlusion (initially non-vascularised zone) and secondarily by cardiac remodelling in the context of the heart failure (HF). In usual practice, cardiac denervation which intensity is correlated with rhythm and mortality risks, can be evaluated by scintigraphy. In a murine reperfusion model of ischemia, the direct anti-inflammatory effect of colchicine reduces the size of the necrosis and improves post-ischemic remodeling. This suggests that colchicine may reduce myocardial denervation.
