What causes variant angina symptoms?

The symptoms of variant angina pectoris are mainly caused by spasm of coronary artery.

Variant angina pectoris is one of the disease types of angina pectoris, which is mostly induced by adverse factors such as smoking and drinking. The coronary artery of the patient is stimulated by the above factors to produce temporary spasm, which leads to insufficient blood supply to some myocardial cells. At the same time, it stimulates the excitation of cardiac autonomic nerves, and clinical symptoms such as precordial pain and syncope will occur.

Because the cause of variant angina pectoris is difficult to correct, it is usually impossible to cure. However, patients actively accept clinical treatment after diagnosis of the disease to improve cardiac blood supply, which can delay the development of the disease and improve the prognosis of the disease.
