Causes of angina in young people

Angina occurs in young people, often because of overwork, emotional excitement, staying up late, or a series of unhealthy lifestyles such as smoking and drinking. In these cases, the sudden increase in cardiac load causes the heart rate to increase, and the tension and contractility of the myocardium increase, resulting in increased oxygen consumption of the myocardium. Angina can be triggered when the blood supply cannot meet the demand. Smoking also reduces the release of prostacyclin, making it easier for platelets to adhere to and aggregate in arterial walls. Nicotine in tobacco can also act directly on coronary arteries and heart muscle, causing arterial spasm and myocardial damage that can lead to angina pectoris. In addition, angina pectoris may also occur in young patients with heart diseases such as myocarditis and congenital cardiomyopathy.
