Elderly coronary heart disease can not be generalized, mild coronary heart disease will not affect the survival time, the condition of serious survival time will be significantly shorter, different patients have obvious differences. Elderly coronary heart disease is a serious narrowing of the coronary arteries, some patients belong to the mild patients, do not need to implant a stent, such as usually able to adhere to the medication, the condition did not appear rapid progress, the patient’s survival time is relatively long, and even will not be affected by the coronary artery lesions. A small number of elderly patients with very serious coronary artery disease, such as diffuse lesions, can not be surgically treated, with the risk of myocardial infarction, the risk of sudden death of the patient is also relatively large, the specific survival time can not be determined, there is a significant difference to the patient. Survival time of elderly patients is also affected by other diseases, such as chronic obstructive pulmonary disease, malignant tumors, will also shorten the survival time of patients. Elderly patients with coronary artery disease should be treated regularly under the guidance of physicians to improve the quality of life and prolong survival time.
