The symptoms of angina pectoris in young people are also dominated by discomfort and pain in the precordial region, mainly occurring behind the sternum, in the precordial region, and in some cases radiating to the left shoulder, the inner left arm or the neck or throat. The pain is also a sensation of pressure tightness or heartburn caused by the sensation of oxygen deprivation. During an attack, the original activity is often stopped until the symptoms are relieved. In young people, many episodes are triggered by emotional excitement or strenuous physical activity, or by eating or smoking.
