Long-term bad mood does not get coronary heart disease. Coronary heart disease is the abbreviation of coronary atherosclerotic heart disease, and its core pathological changes are atherosclerosis of the coronary arteries, arterial plaques, and even the occurrence of coronary artery stenosis, insufficient blood supply to the coronary arteries and so on. Causes of coronary heart disease include hypertension, diabetes, hyperlipidemia, hyperhomocysteinemia and other diseases. Chronic bad mood may cause depression and anxiety and other psychiatric disorders, but it does not lead to atherosclerosis, which does not cause coronary heart disease. Chronic bad mood may cause symptoms similar to insufficient blood supply to the coronary arteries, such as discomfort in the precordial region, but there is no abnormality in the electrocardiogram or coronary arteriogram, which can help to identify it. Both chronic moodiness and coronary artery disease may cause precordial discomfort, and therefore require medical treatment as soon as possible.
