After cardiac stenting, you can do simple physical exercise for a short period of time, and after about six months, you can start to do light physical work, but it is not recommended to do heavy physical labor. Although the coronary vessels have been recanalized after cardiac stenting, the myocardial cells may still be necrotic and damaged, and the damaged myocardial cells need a certain period of time to be repaired, and physical labor during the recovery of the myocardial cells may induce new myocardial ischemia and necrosis or even heart failure, therefore, patients should avoid heavy physical activities in the short term after cardiac stenting. After half a year’s review after cardiac stenting, to make sure that the patient’s heart function has recovered well and the stent is functioning well, the patient can start to engage in some slightly heavier physical labor, but be sure to pay attention to the intensity should not be too large, once the labor appears to be unwell, take a rest in a timely manner, and go to the hospital for medical treatment if necessary.
