The Impact of Phase I Cardiac Rehabilitation on the Prognosis of AMI Patients After PCI

Inclusion Criteria: 1. Patients with AMI (including STEMI and NSTEMI) who were treated in the CCU (Coronary Care Unit) for more than 12 hours after emergency PCI; 2. Patients who are expected to meet the discharge criteria without the need for repeat PCI during the current hospital stay after PCI; 3. No chest pain episodes within 8 hours, with no recurrence of myocardial infarction; remained hemodynamically stable; 4. No further increase in serum levels of cardiac biomarkers such as Creatine Kinase -MB (CK-MB) and cardiac troponins (cTn). Exclusion Criteria: 1. Patients with Killip class III or higher, or symptoms and signs of acute pulmonary edema and respiratory distress; 2. Malignant arrhythmias that cause hemodynamic instability and potentially life-threatening conditions; 3. Mechanical lesions such as ventricular wall rupture, valve or tendon rupture; 4. Patients who have not yet been weaned off ECMO, IABP, temporary pacemakers, CRRT; 5. Patients with liver or kidney dysfunction (transaminase exceeded three times the upper limit of normal; EGFR\<30 ml/(min·1.73m\^2)) or advanced malignant tumors; 6. Patients who cannot undergo exercise rehabilitation due to orthopedic or psychiatric diseases; 7. Patients with language impairment; 8. Patients currently undergoing systematic training or participating in other clinical trials without reaching the primary endpoint collection time; 9. Researchers believe that patients are not suitable for participation in this study or have not obtained an informed consent form.
