Incidence Rate of Heart Failure After Acute Myocardial Infarction With Optimal Treatment

the study aim to enroll 12000 acute myocardial infartion (AMI) patients, including ST-segment elevation myocardial infarction (STEMI) and non ST-segment elevation myocardial infarction (NSETMI), Patients were divided into two groups(optimized group and un-optimized group) according to treatment models they accepted in 20 reginally representative hosptials of China. whether optimizaed or not is judged by 4 four aspects,including emergency treatment procedure, pre-infusion medication, reperfusion strategy selection, and early rehabilitation after reperfusion.Patients were followed at 1 month, 6 months and 12 months. The physical condition and clinical events(heart failure, death, re-infarction, revascularization, apoplexy, malignant arrhythmias, bleeding events, other adverse events)were collected at follow up.

Inclusion criteria

• diagnosed acute myocardial infarction
• signed the informed consent form

Exclusion criteria

• AMI is caused by surgery, trauma, gastrointestinal bleeding or complications of PCI;
• AMI occurred in patients who have been hospitalized for other reasons;
