If a patient develops sweating during angina pectoris, it needs to be identified from both Chinese and Western medicine. From the point of view of Chinese medicine, sweating is caused by a deficiency of qi and blood in the heart. In addition, from the perspective of Western medicine, when the patient has angina pectoris, the patient has coronary atherosclerotic heart disease, and most of them are combined with unstable angina pectoris, and the patient has ischemia, spasm and narrowing of coronary arteries, which leads to insufficient supply of blood and oxygen to myocardial cells, and then the clinical symptoms of sweating will appear. For patients with previous endocrine metabolic diseases, such as thyroid system dysfunction, in angina pectoris, there will also be sweating. In patients with diabetes mellitus, sweating also occurs in angina. If severe angina leads to cardiogenic shock, sweating can occur.
