Patients with myocardial infarction atypically present with a sore throat, or numbness and discomfort in the jaw. The most effective way to confirm the diagnosis is to perform an electrocardiogram, which can initially clarify the diagnosis. If necessary, it can also be further combined with coronary angiography, which can also clearly detect the exact lesion site of the narrowed or infarcted vessel. For myocardial infarction, mainly hypertension and heart disease, acute attacks can be induced by exertion, emotional fluctuations, trauma or cold, and patients will experience crushing pain in the precordial region, accompanied by chest tightness, nausea, vomiting, and in severe cases, malignant arrhythmias. After the diagnosis is confirmed, the patient should be treated actively with nitroglycerin and drugs to improve microcirculation. In general, we should pay attention to a low-salt, low-fat diet, and also take appropriate vitamin-rich food, and pay attention to systematic anti-atherosclerosis and lipid regulation treatment.
