COLchicine and Thiamine in Heart Failure Due to Ischemic Heart Disease

Обзор

The goal of this 2x2 factorial clinical trial is to test the efficacy of i) colchicine, and ii) thiamine in heart failure (HF) secondary to ischemic heart disease. The main questions it aims to answer are: * Does colchicine reduce the risk of cardiovascular (CV) death, a HF event, or an ischemic CV event * Does thiamine reduce the risk of cardiovascular (CV) death, or a HF event Participants will undergo the following procedures: * Run-in: All participants will receive colchicine 0.5 mg daily to assess drug tolerance over a 3-4 week period. * Randomization: If colchicine is tolerated during run-in, eligible participants will be randomized in a 2x2 factorial design to receive i) colchicine 0.5mg daily or placebo, and ii) thiamine 300mg daily or no thiamine. * Follow-up: Clinical outcomes, side effects, adverse events, and drug adherence will be captured during follow-up

Критерии участия

Критерии включения

• Age >/= 45 years
• Documented ischemic HF as the etiology of HF, which includes:

• a prior history of CAD (defined as a history of myocardial infarction, coronary artery bypass graft surgery, percutaneous coronary intervention, or non-invasive or invasive cardiac testing consistent with a diagnosis of CAD), and
• determination of CAD to be the cause primary cause of HF based on local investigator assessment
• New York Heart Association (NYHA) class II-IV symptoms
