Myocardial ischemia is a clinical condition in which coronary blood flow is reduced for various reasons, resulting in insufficient supply of oxygen and other substances to the myocardium and reduced removal of metabolic products. A lot of bad habits in daily life may cause myocardial ischemia, and the impact of this disease on our body can not be underestimated, the following we come together to understand what impact myocardial ischemia on patients. 1, the cause of myocardial ischemia is the narrowing of the blood vessels of the heart, making the supply of blood and nutrients for the heart to work is not enough to cause the disease. Myocardial ischemia can have many negative effects on the heart and the whole body. Oxygen is essential for the activity of heart muscle cells, and oxygen is delivered to the cells through the bloodstream. The heart does not have an “oxygen storehouse” and relies entirely on myocardial blood supply, so once ischemia occurs, it immediately causes hypoxia. Some myocardial ischemia may not have other signs and symptoms, but clinical examination suggests myocardial ischemia. So patients with myocardial ischemia must pay attention. 2, myocardial ischemia is very easy to cause myocardial hypertrophy, left ventricular enlargement, and gradually develop into heart failure. Myocardial ischemia may also cause various arrhythmias, such as premature beats, atrial fibrillation, sick sinus syndrome, conduction block, tachycardia and so on. Some patients have a history of angina pectoris, myocardial infarction, often accompanied by hypertension. Long-term myocardial ischemia can also lead to myocardial necrosis and myocardial fibrosis, the left ventricular function will be completely “damaged”, losing the “ability to work”. This disease is very harmful to patients. 3, myocardial ischemia can also cause insufficient blood supply. Because myocardial ischemia leads to insufficient blood supply to the heart itself, clinically, patients can control and alleviate the symptoms of myocardial ischemia through traditional Chinese medicine, patients have to take medication for life, it is unlikely that complete recovery. In addition to pay attention to diet, low fat and high fiber. Emotional attention should be paid not to great joy and great sorrow, maintain sufficient sleep. Develop good habits, regular bowel movements, not overworked. So patients with myocardial ischemia must pay attention to daily conditioning. Many people will have discomfort in the chest and abdomen, precordial area, non-precordial area, probably due to myocardial ischemia, in the daily life of such symptoms, must pay attention to dietary health, eat less food high in cholesterol, high fat, high calorie, can be prevented from the root, more importantly, we must actively seek medical treatment.
