Life after stent surgery life is affected by a variety of factors, part of the life expectancy can be the same as normal, but a small number of postoperative complications can affect life expectancy or even sudden death. Cardiac stent surgery can temporarily unblock the coronary arteries and improve the blood supply to the heart, thus saving the life of heart attack. After some successful surgeries without other discomforts and paying attention to active postoperative care, life expectancy is usually not affected or even prolonged due to the improvement of the disease. However, if the postoperative period is not actively cared for, it may cause postoperative bleeding or make blood clots, which may aggravate the condition and thus have a certain impact on life expectancy. If not corrected in time, it may even lead to sudden death. After cardiac stenting, you must pay attention to regular review of ECG, coronary angiography, etc., if there is any abnormality, it should be diagnosed and treated in a timely manner.
