What are the treatment methods for extensive myocardial infarction?

Extensive myocardial infarction, also known as acute ST-segment elevation myocardial infarction, is the death of heart muscle tissue caused by severe and prolonged ischemia and hypoxia due to acute occlusion of the coronary artery. Treatment mainly includes the following aspects:

1. Medication therapy: Thrombolytic drugs, such as recombinant streptokinase for injection and urokinase for injection, are used to dissolve blood clots blocking the coronary arteries and restore blood supply to the heart muscle; analgesic drugs, such as aspirin enteric-coated tablets, ibuprofen tablets, and celecoxib capsules, are used to relieve the patient's pain; drugs for improving myocardial blood supply, such as beta-blockers, nitrates, and calcium channel blockers, are used to improve the blood supply condition of the heart muscle.

2. Cardiac rehabilitation: After the patient's condition stabilizes, cardiac rehabilitation training is conducted, including aerobic exercise, psychological support, nutritional guidance, and smoking cessation counseling, which helps improve the patient's quality of life and prognosis.

3. Monitoring and management of complications: Complications such as arrhythmia, heart failure, and cardiac rupture must be closely monitored and promptly treated.
