There are plaques in the heart and chronic ischemia for a long time. Without proper treatment, myocardial fibrosis will occur due to long-term ischemia, which will eventually lead to heart failure. Acute coronary syndrome and chronic coronary disease are diametrically opposite, and belong to the situation of unstable plaque. Including acute myocardial infarction and unstable angina pectoris. Blood oxygen energy needs to be infused into all organs and activities of human body. Once the blocked coronary blood vessels affect the blood oxygen delivery, it will affect the normal balance of human body and produce a series of clinical symptoms, and this effect will last for a long time. Therefore, patients with severe coronary heart disease are prone to heart failure and death.
The most common manifestations of patients with coronary heart disease are angina pectoris, myocardial infarction, arrhythmia, heart failure and sudden death, among which the most common is angina pectoris, which is mainly manifested as crush-like pain in the precordial area related to activities, which can be radiated to the back and upper limbs, and can be relieved in a few minutes to ten minutes after rest. The prevention of coronary heart disease is mainly to control blood pressure, blood sugar, blood lipid, quit smoking and alcohol, control weight, etc., and control the susceptible factors of coronary heart disease.
Personality often has abnormal platelet activity, which leads to abnormal coagulation mechanism, especially in patients with depression. Under acute stress, coronary artery spasm, vulnerable plaque rupture and local thrombosis are prone to occur, which leads to acute coronary events. General mental illness is caused by serious dysfunction of cerebral cortex. Serious dysfunction of cerebral cortex will also weaken the control and integration of subcortical centers, leading to dysfunction of autonomic nerves in relevant centers.
