How long you can exercise after stenting depends on the specific condition, patients with angina can have appropriate activities two weeks after the operation, and patients with myocardial infarction should start to have gradual activities about one month after the operation. For patients with stenting, some of them may have simple angina pectoris and limited narrowing of coronary arteries, which can be rapidly recovered by implanting a stent, and they can be properly active two weeks after the operation. Stent implantation can also be used in acute myocardial infarction, although it can open the occluded blood vessel in time, but there will be varying degrees of myocardial necrosis. Myocardial necrosis cannot be completely normalized, but recovery of the ischemic site takes about 3-6 months. In patients with acute myocardial infarction, it is recommended to be appropriately active after the condition has completely improved, so as not to increase the load on the heart, which can lead to abnormal remodeling of the ventricles and increase the risk of heart failure. Patients after stenting should assess the severity of their condition, develop an exercise prescription under the guidance of their physician, and exercise in a scientific and rational manner.
