The survival time of coronary heart disease is related to various reasons such as individual patient’s condition, treatment method and age, and cannot be generalized. Coronary heart disease is coronary atherosclerotic heart disease, mainly due to the aorta, coronary artery blood vessel wall local calcification, resulting in varying degrees of narrowing inside the lumen, thus causing insufficient blood supply to the heart and the corresponding symptoms. Patients with coronary artery disease often manifest chest tightness, breathlessness, palpitations after activity, and pressure-like pain at the back of the sternum during an attack. Patients with mild coronary artery stenosis do not feel any obvious discomfort, but when moderate to severe stenosis occurs, it will lead to corresponding symptoms. If coronary artery disease is detected at an early stage, and early intervention measures are taken to improve bad habits, such as smoking, drinking and staying up late, emotional excitement, etc., and to control high risk factors such as blood glucose, blood pressure, and blood lipids, the patient’s life expectancy will be the same as that of a normal person. However, in case of acute infarction, severe heart failure, etc., the patient’s life will be in danger at any time. Therefore, it is recommended that patients take early measures to interfere with discomfort, pay attention to rest, and improve their lifestyles.
