The duration of life with stenting for more than 90% blockage of cardiac vessels depends on the site of blockage and the specific situation of the patient, and cannot be generalized. If the blockage occurs in the coronary collateral vessels of the heart, the patient has no other complications after the operation, the stent is well maintained, no heart failure is combined, and timely, standardized and systematic treatment is provided, the prognosis is usually good and there is no major impact on life expectancy. If acute large myocardial infarction caused by blockage of a large blood vessel in the heart is prone to complications such as heart failure, it will seriously affect life expectancy. If it causes severe heart failure, patients’ life expectancy is mostly 5-10 years. Patients with more than 90% blockage of cardiovascular vessels are recommended to go to the cardiovascular department of regular hospitals in time, take drugs to control the condition before surgery, pay attention to rest, avoid straining, and do not engage in strenuous activities.
