After strenuous exercise that manifests as chest pain, you should stop exercising and sit down to rest. In addition, if the pain persists without relief, an electrocardiogram as well as a cardiac ultrasound should also be performed promptly. Especially for elderly patients, if they have underlying diseases, such as hypertension and diabetes, after strenuous activity, they tend to have insufficient blood supply to the myocardium and show pain and discomfort in the precordial region, and also chest tightness or panic, and if necessary, they need to give nitrate drugs. If necessary, oral medications to improve blood supply to the heart or to prevent coronary artery disease, such as aspirin, antiplatelet, or betalactam, are commonly used to control the heart rate. In daily life, attention should also be paid to monitoring blood pressure, and attention should be paid to a low-salt, low-fat diet.
