The most likely cause of heart cramp-like pain, i.e. heart clenching-like pain, is coronary angina, which manifests as paroxysmal pain in the precordial region due to narrowing of coronary arteries, or coronary artery spasm resulting in reduced coronary blood flow, causing inadequate myocardial blood supply, resulting in myocardial ischemia and hypoxia, resulting in pain and heart discomfort. If the pain lasts for several minutes to relieve, consider angina attack, if the pain lasts for too long, more than 30 minutes without relief, consider the possibility of myocardial infarction. Normally, you should pay attention to a low-salt and low-fat diet, regular life, appropriate exercise, pay attention to warmth and avoid prolonged sitting. In addition, you can also apply hot compresses and massage, all of which can help relieve the symptoms. When heart cramps seem to be painful, go to the hospital early to check the electrocardiogram for a clear diagnosis. In addition, it may also be caused by cardiac neurosis, especially in patients with severe anxiety or severe depression, which can also appear heart discomfort.
