Coronary heart disease generally refers to coronary atherosclerotic heart disease. Patients with coronary atherosclerotic heart disease generally live for 30 years or even longer, but due to the variability of individuals, it is impossible to generalize. Coronary arteries are the arteries that supply blood to the heart. When atherosclerosis occurs in the coronary arteries causing narrowing or occlusion of the lumen of the arteries, it will lead to myocardial ischemia and lack of oxygen, and the patient will suffer from a series of uncomfortable symptoms. Patients with atherosclerotic coronary heart disease can survive for about 30 years if their condition is mild and active treatment measures are taken at an early stage, and some patients with good recovery can survive for a relatively longer period of time, which cannot be specified. However, if patients do not take timely treatment measures, leading to the development of the disease and complications such as heart failure, arrhythmia and insufficient blood supply to the brain, it may lead to the death of the patient, and the survival time is drastically shortened. Therefore, once diagnosed with coronary atherosclerotic heart disease, patients need to actively cooperate with doctors to take relevant treatment measures to avoid delays.
