Angina pectoris is a group of syndromes caused by insufficient blood supply to coronary arteries due to atherosclerotic stenosis of coronary arteries, and myocardial temporary ischemia and hypoxia, with pain in the anterior region of the heart as the main clinical manifestation. At present, the incidence of angina pectoris is increasing year by year, seriously jeopardizing the health and life of the people. If angina pectoris continues to develop, it greatly increases the risk of myocardial infarction and sudden cardiac death, and must be given adequate attention. Clinical manifestations of angina pectoris Typical angina pectoris symptoms: sudden onset of the upper part of the sternum or the middle part of the body after the oppressive, stuffy pain, can be radiated to the left shoulder, the left upper limb in front of the inner side, up to the ring finger and pinky, occasionally accompanied by the sense of imminent death, and sweating in severe cases.
