Whether coronary heart disease can do physical work needs to be decided according to the type of coronary heart disease and cardiac function grading. According to the characteristics of coronary heart disease and treatment principles are divided into chronic coronary artery disease (stable angina, ischemic cardiomyopathy and insidious coronary heart disease) and acute coronary syndrome (such as unstable angina, myocardial infarction, etc.) can not do physical work, there is a risk of death. Chronic coronary artery disease is categorized into four grades according to the Canadian Society of Cardiovascular Disease’s angina severity scale, with each grade corresponding to a different level of disease severity and a different level of physical activity that can be tolerated. Grade I can do light physical activities, such as climbing stairs and walking, but not fast, strong physical activities that could trigger the disease. Grade II and above is not recommended to do physical activities, this time if you do physical activities, most people will be uncomfortable after the activity (such as chest tightness, shortness of breath, dyspnea, etc.), forced to continue to work will aggravate the condition or even affect the prognosis. Remember whether coronary heart disease can do physical activity, must find a doctor for cardiac function assessment, follow the doctor’s instructions.
