Myocardial ischemia mainly refers to the relatively low blood perfusion to the heart, which will lead to the reduction of oxygen supply to the heart followed by abnormal myocardial energy metabolism, and generally cannot support the normal work of the heart. And coronary artery narrowing or occlusion caused by coronary atherosclerosis is the most important and common cause of myocardial ischemia, which will directly lead to myocardial ischemia and hypoxia, and will cause heart disease, which is often referred to as coronary heart disease. How can myocardial ischemia be treated? The common causes of myocardial ischemia are coronary atherosclerosis, as well as inflammation, spasm. Embolism, as well as connective tissue disease or trauma and congenital malformations and other multi-class factors. According to experimental studies, important risk factors associated with atherosclerosis are hyperlipidemia, hypertension, diabetes mellitus, obesity, low physical activity and advanced age. The treatment of myocardial ischemia is mostly based on pharmacological therapy, first of all, anti-platelet drugs. For example, aspirin, clopidogrel, etc. can prevent thrombosis and also avoid coronary artery and cerebral artery thromboembolism. Then there are drugs such as metoprolol that can slow down the heart rate and reduce the oxygen consumption of the heart muscle. There are also statins, such as atorvastatin, which can effectively lower plasma cholesterol, stabilize arterial plaque, and prevent the formation of blood clots. Some nitrates are effective in dilating the coronary arteries and increasing the blood supply to the heart muscle. Interventional therapy can also be used. Coronary intervention is a milestone in the history of coronary artery disease treatment in recent years, and it is a painless and minimally invasive method for patients. It is widely accepted by patients because of its minimal trauma, quick recovery and short hospital stay. Patients with myocardial ischemia can be examined using coronary angiography and, if necessary, stent placement. Severe cases can be treated surgically. Patients with myocardial ischemia should pay attention to their diet. Patients should pay attention to a low-salt, low-fat, light diet, and eat more vegetables such as carrots and tomatoes, which can improve the resistance of the patient’s body. Also drink some green tea, tea contains a small amount of theophylline, has a certain diuretic effect on the patient’s myocardial ischemia treatment, and can also prevent atherosclerosis. It is also important to insist on eating some black fungus every day, which can help to reduce blood viscosity and improve myocardial ischemia. Patients should pay attention to emotional stability, also keep enough sleep, develop good habits, and not too strenuous. With persistence, health will be restored soon.
