Coronary heart disease does not attack every day, but if it is not treated in a standardized manner, it may lead to aggravation of the condition, thus endangering the life and health of the individual. Coronary heart disease is generally caused by the narrowing or occlusion of the lumen of the coronary arteries. The most typical symptoms are chest pain, chest tightness, and dyspnea, which usually occur after strenuous exercise. There is no real cure for this disease as the cause cannot be eradicated. After the diagnosis is confirmed, there are corresponding medications under the guidance of professional doctors, such as Bisoprolol, Atenolol, Aspirin, Simvastatin, Nicorandil and so on, to slow down the progression of the disease, and to reduce angina pectoris as well as myocardial infarction episodes. Once the disease is under control, it will not attack every day. However, if the disease is not treated in time after diagnosis, the patient may die due to myocardial infarction, heart failure or malignant arrhythmia caused by coronary artery disease, which may jeopardize the patient’s life and health, but coronary artery disease does not attack every day. The treatment of coronary heart disease is generally based on drug therapy and surgical treatment, and the specific treatment method should be decided according to the severity of coronary heart disease. Disease in the treatment period, the patient must avoid too strenuous exercise and emotional fluctuations, so as not to increase myocardial oxygen consumption, causing angina pectoris, or even induced myocardial infarction.
