There is no accurate epidemiological survey and statistics on how long 50-year-old patients with 4 stents can live. Regular use of medication with good disease control and no other underlying diseases will not affect life expectancy, on the contrary, there may be a shortened life expectancy or even the possibility of death at any time. 1.4 stents in 50-year-old patients, indicating that the patient’s coronary arteries have multiple serious stenosis, the blood supply of the heart has been seriously threatened, after placing the stent, if the patient can adhere to the regular use of antiplatelet drugs and lipid-regulating drugs, and there is no combination of other underlying diseases, it will not lead to a significant shortening of the life expectancy. 2. If patients do not take aspirin, atorvastatin and other basic drugs regularly after stent placement, stenosis may reoccur within the stent, leading to a shortened life expectancy or even sudden death. 3. Some patients may suffer from postoperative cardiac insufficiency. If accompanied by severe heart failure, the patient’s survival time will be significantly shortened. If accompanied by other serious diseases, such as diabetes mellitus, etc., it may lead to coronary artery stenosis again, which may lead to sudden death of the patient at any time. Patients after stenting should adhere to the medication and under the guidance of the doctor in order to prolong the survival time.
