Coronary artery heart disease (CHD) is the most common form of heart disease and is also known as ischemic cardiomyopathy (IHD) because of myocardial dysfunction and/or organic lesions caused by narrowing of the coronary arteries and inadequate blood supply. CHD is the result of several coronary artery diseases, but coronary atherosclerosis accounts for the vast majority of coronary heart disease (95 to 99%). Therefore, it is customary to think of CHD as coronary atherosclerotic heart disease (CAD). Symptoms of coronary heart disease include a crushing pain in the center of the chest that may extend to the neck, jaw, arms and stomach. It is not the same as angina, and it remains even after you stop exercising or after the tension subsides. Other possible symptoms of a coronary heart attack are vertigo, shortness of breath, sweating, chills, nausea and fainting. Severe patients may die from heart failure due to an acute massive heart attack. Coronary heart disease is a disease with a very high rate of sudden death. Its treatment includes three treatment options, namely drug therapy, interventional therapy (PTCA plus stent) at the Cardiovascular Disease Clinic and cardiac surgery bypass surgery. Drug therapy is the most basic treatment, and once diagnosed, drug therapy should be maintained for life in any patient. However, when drug therapy is ineffective or ineffective, coronary angiography should be done as soon as possible to evaluate the coronary lesions in detail, and then decide whether to choose interventional therapy and/or bypass surgery according to the patient’s coronary lesions and the patient’s financial status. Bypass surgery is the best long-term effect among the current treatment methods. And with the continuous improvement of surgical techniques, the success rate of the procedure is very high and the patient recovers quickly after the procedure. Interventional treatment (PTCA plus stent) is less invasive, but more expensive for patients, and still untreatable for some patients with lesions such as coronary bifurcation and severe proximal stenosis with calcification. Coronary artery disease should be primarily prevented, and early detection and treatment should be achieved, and serious massive myocardial infarction should be avoided as much as possible. Patients with coronary heart disease should try to do the following: 1. Eat a reasonable diet, do not be partial and should not be excessive. High cholesterol and high fat food should be controlled, and more vegetarian food should be eaten. Also to control the total calorie intake and limit weight gain. 2, life should be regular, avoid excessive tension; keep enough sleep, cultivate a variety of interests; keep emotional stability, avoid impatience, excitement or sullenness. 3, maintain appropriate physical exercise activities to enhance physical fitness. 4, do not smoke, alcohol, smoke can make the artery wall contraction, promote atherosclerosis; and alcohol is easy to emotional excitement, blood pressure rise. 5, actively prevent and treat chronic diseases of the elderly, such as hypertension, hyperlipidemia, diabetes, etc., these diseases are very close to coronary heart disease.
