Resumption of exercise after cardiac stent implantation depends on the patient’s physical condition and the extent of the disease. If the patient is implanted with a stent because of angina pectoris at the beginning, and after the blood supply is improved, the heart function will return to normal in a short period of time, then the patient can start to increase the exercise gradually about half a month after the symptom disappears, and the patient can start from the simple action such as getting up and standing up at the beginning, and gradually increase the exercise, and can return to the normal activity about one month and one month later. Because blood flow improves after implantation of stent for myocardial infarction, symptoms are relieved or even disappeared, the recovery time of heart function is relatively long, and even long-term symptoms of shortness of breath and stuffiness after activity occur. This kind of patients mainly pay attention to rest after the operation, and after 1~3 months, gradually and gradually increase the exercise according to their own conditions, such as brisk walking, swimming, cycling and so on. Regardless of the recovery from implantation of the stent, it is important to be on time for review, and accurate exercise advice will be given by the medical staff after the review and evaluation.
