Intermittent pain in the chest area cannot be ruled out as a result of myocardial ischemia, and an electrocardiogram should be performed promptly to further clarify the cause of myocardial ischemia. Exertion, overeating, alcoholism, mood swings, and cold stimulation can occur, and there is a trend toward younger patients. Elderly patients with hypertension and a perennial diet containing too much salt can easily lead to increased blood pressure, and the patient can also have arteriosclerosis or even vascular occlusion. So arterial spasm can also appear as insufficient blood supply to the heart muscle, and the patient shows pain in the chest area, radiating to the back of the left shoulder, and also symptoms such as chest tightness and panic. It is also important to pay attention to a low-salt and low-fat diet, appropriate activities, and regular related examinations.
