Guidance: At this time, the patient's exercise needs to be "step by step". Patients should be encouraged to participate in various daily activities, including eating and dressing, sweeping the floor and watering the flowers, buying food and walking, working and entertaining, and even having sex, so that patients can gradually return to normal life and work, but there must be a limit: any activity that causes chest pain or shortness of breath will be. Try slowly and get used to it. I hope my answer is helpful to you, and I wish you health and happiness.
