Myocardial infarction, also known as acute myocardial infarction, is a serious cardiovascular disease characterized by the death of myocardial cells due to prolonged ischemia. This disease mostly occurs on the basis of coronary artery disease. When the blood supply to the coronary arteries sharply decreases or is interrupted, the corresponding myocardium will suffer from severe and persistent acute ischemia, leading to myocardial infarction.

Clinical manifestations of myocardial infarction

The clinical symptoms of myocardial infarction are diverse, but in the early stages, pain is the main symptom, often manifested as sudden chest compressional pain, which may radiate to the lower jaw, neck, and upper back. In addition, patients may also experience systemic symptoms, gastrointestinal symptoms, arrhythmia, hypotension and shock, heart failure, etc. The incidence of myocardial infarction increases with age, especially in middle-aged and elderly people over 40 years old. At the same time, hypertension, obesity, diabetes, chronic renal insufficiency, etc. are also important risk factors.

The latest treatment methods for myocardial infarction

At present, the treatment methods for myocardial infarction mainly include the following:

Thrombolysis therapy: Restoring blood flow by dissolving fibrin in the thrombus. This method is mainly suitable for patients who have no contraindications for thrombolysis within 6 hours after the occurrence of acute myocardial infarction. Commonly used drugs include streptokinase, alteplase, etc.

Percutaneous coronary intervention (PCI): Using a catheter to open a blocked coronary artery under X-ray monitoring, commonly used instruments include balloon dilation catheters and stents. PCI has become an important treatment for acute myocardial infarction, especially for patients with severe heart failure. Selective PCI should be performed as early as possible after the condition stabilizes.

Coronary artery bypass grafting (CABG): When both drug therapy and PCI are ineffective, CABG may be considered. This is a surgery that involves redirecting one's own blood vessels from the aorta to a narrowed or blocked area to bypass the lesion site, often using one's own internal mammary artery or great saphenous vein as a graft.

Anticoagulant therapy: aimed at preventing blood clotting, usually using heparin or oral anticoagulants such as warfarin. Anticoagulation therapy can prevent and reduce thrombosis, and is an important part of the treatment of myocardial infarction.

Lipid lowering medication treatment: By reducing blood lipid levels and improving blood circulation. Common medications include statins (such as atorvastatin) and fibrates (such as fenofibrate). Lipid lowering drugs play an important role in the prevention and treatment of myocardial infarction.

In summary, there are various treatment methods for myocardial infarction, and with the advancement of medical technology, its treatment effectiveness is constantly improving. However, preventing the occurrence of myocardial infarction remains one of the most important measures, including maintaining a healthy lifestyle, controlling blood pressure, blood sugar, and lipid levels.
