Non-ST Segment Elevation Myocardial Infarction

Inflammation plays a central role in the pathophysiology of atherosclerosis and in the progression of coronary artery. Colchicine, an anti-inflammatory agent traditionally used for gout and pericarditis, has emerged as a potential therapy in cardiovascular disease due to its ability to inhibit microtubule polymerization and suppress interleukin-1β and the NLRP3 inflammasome pathway. COLCOT and LoDoCo2 trails have demonstrated the efficacy of colchicine in reducing cardiovascular events in patients with coronary artery disease. However, more recent trials, including OASIS 9 and COVERT-MI trials did not support the use of a short-term colchicine treatment at the acute phase of ST segment elevation myocardial infarction (STEMI) to reduce infarct size and improve outcomes. Limited data exist on the peri-procedural use of colchicine in non-ST elevation myocardial infarction patients undergoing PCI. This study proposes to assess whether a loading dose of colchicine before PCI, followed by 3-months maintenance therapy, can improve short-term clinical outcomes and inflammatory markers in non- STEMI patients.

This trial is designed to evaluate whether low-dose colchicine, in addition to standard treatment recommended by guidelines, further reduces the risk of major adverse cardiovascular events in patients with acute coronary syndromes (ACS) through a prospective, randomized, double-blind, placebo-controlled clinical trial.
