To determine the therapeutic effects of Tongxinluo Capsules as compared with placebo in the treatment of patients with acute ST-elevation myocardial infarction (STEMI): (1) Clinical efficacy and safety at 30 days: the incidence of composite endpoints comprising major adverse cardiovascular and cerebrovascular events (MACCE, including cardiovascular death, myocardial re-infarction, emergency coronary revascularization and cerebral stroke), severe complications (including cardiogenic shock, heart failure, mechanical complications and malignant arrhythmias), and major bleeding (BARC grade III and V); (2) Clinical efficacy and safety at 1 year: the incidence of composite endpoints comprising MACCE, hospitalization due to heart failure, in-stent thrombosis, and major bleeding (BARC grade III and V), as well as all-cause mortality; (3) the effects in promoting myocardial reperfusion, reducing incidence of myocardial no-reflow, protecting ischemic myocardium, minimizing infarction size, and improving left ventricular systolic function.
