The 5-year survival rate for coronary artery disease refers to the percentage of patients with coronary artery disease who survive after 5 years of various comprehensive treatments. Coronary heart disease is the abbreviation of coronary atherosclerotic heart disease. It is a disease of myocardial ischemia, hypoxia and necrosis caused by atherosclerosis of the coronary arteries leading to narrowing or occlusion of the lumen of the coronary arteries. Symptoms such as chest tightness, chest pain, dyspnea, and fatigue may occur. The 5-year survival rate for coronary artery disease is generally over 90%. And coronary artery disease involving the scope of myocardial blood supply and impaired cardiac function. Coronary heart disease can follow the doctor’s advice to take nitroglycerin and other drugs to improve myocardial ischemia, but may lead to headache, low blood pressure and other side effects; can also be used with aspirin and other anti-platelet drugs, but may lead to bleeding and other side effects. It can also be combined with lipid-regulating drugs such as simvastatin, but it may lead to side effects such as allergies and liver function damage. After the above treatment, the 5-year survival rate is usually above 90%, and the specific survival time is related to the degree of coronary atherosclerosis and treatment.
