A Study of Pirfenidone in the Treatment of Myocardial Fibrosis After Acute Myocardial Infarction: a Phase II Prospective, Randomized, Double-blind，Placebo Controlled Clinical Trial (PROTECT-AMI)

NCT05531955 Phase 2 UNKNOWN

Acute myocardial infarction (AMI) is myocardial necrosis caused by acute and continuous ischemia and hypoxia of coronary artery. It can be complicated with arrhythmia, shock or heart failure, which is often life-threatening. The disease is the most common in Europe and the United States, where about 1.5 million people suffer from myocardial infarction every year. China has shown an obvious upward trend in recent years, with at least 500000 new cases every year and at least 2 million current cases . At present, China has a high incidence rate of heart failure after myocardial infarction. The incidence of heart failure within 7 days after myocardial infarction is 19.3%, and the incidence of heart failure from 30 days to 6.7 years after myocardial infarction is 13.1%\~37.5%. The incidence of heart failure after myocardial infarction significantly increases the risk of short-term and long-term death, and the prognosis is poor. At present, there is a lack of unified guidance and norms for the diagnosis, treatment and prevention and control strategies of heart failure after myocardial infarction. Cardiac remodeling is the basic pathological process of heart failure after myocardial infarction, and it is also one of the main factors affecting the prognosis of patients. Studies have shown that 30% of AMI have ventricular remodeling 6 months after percutaneous coronary intervention (PCI), and the risk of ventricular remodeling in anterior wall myocardial infarction is the highest. According to foreign literature data, the probability of ventricular remodeling after anterior wall acute myocardial infarction is about 13%, which is 1.9 times higher than that in other parts.Opening the infarct related coronary artery early can save the dying myocardium, reduce the infarct myocardial area and reduce the loss of cardiomyocytes.
