Whether or not you can swim after having a stent varies from person to person. Swimming is not recommended for patients who have just had cardiac stent surgery, but if the stent has been installed for a longer period of time and the recovery is more stable, you can swim appropriately, but you should also pay attention to the amount of exercise. Swimming is not recommended for patients within three months after having a cardiac stent, because patients with coronary artery disease are mainly resting during the first three months after having a stent installed, and strenuous exercise may induce myocardial ischemia, which may cause patients to experience chest tightness, chest pain and other related symptoms, so they can choose some soothing exercises, such as walking, slow walking, and so on. If the stent has been installed for a longer period of time, if the recovery is good and the heart function is normal, it is possible to swim appropriately, but also pay attention to choose the appropriate amount of exercise according to their own conditions, and try to avoid overwork. After the installation of stent patients should also pay attention to regular review, under the guidance of the doctor reasonable use of medication.
