Colchicine's effect on inflammation during cardiac surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter, randomized, controlled, double-blind trial investigates the impact of colchicine on inflammatory organ injury in patients undergoing cardiac surgery. A total of 768 patients aged 50 to 80 will be enrolled and randomly assigned to receive either colchicine or a placebo before and after surgery. The study will monitor various clinical indicators, including inflammatory markers and organ function, to assess the efficacy of colchicine in reducing perioperative complications. The trial aims to provide insights into the role of colchicine in managing inflammation during cardiac procedures.
