Coronary heart disease (CHD) is a myocardial lesion caused by atherosclerosis or (and) spasm of the coronary arteries that narrow or completely occlude the lumen, and insufficient or interrupted blood supply to the myocardium, also known as ischemic heart disease. The clinical categories are: asymptomatic myocardial ischemia, stable angina, ischemic cardiomyopathy, acute coronary syndrome, and sudden death. Among them, asymptomatic myocardial ischemia (no obvious morphological tissue changes in myocardial cells; history of old myocardial infarction with ischemic manifestations on ECG but no main complaints of discomfort; presence of ischemic attack manifestations on ECG but no clinical symptoms), acute coronary syndrome is an acute attack type of coronary artery disease with three clinical subtypes (unstable angina, acute non-ST-segment elevation myocardial infarction, acute ST-segment elevation myocardial infarction) are currently considered to be clinical manifestations of different stages of the same pathological process. The concept of acute coronary syndrome has been introduced to facilitate clinicians’ grasp of the principles of emergency management of coronary heart disease. CHD is currently one of the most important factors of death and severe disability worldwide, and there are more than 10 million patients with CHD in China, and there is a trend of younger population in the past decade. Over the past decade, epidemiological studies and basic research on CHD risk factors have led to great progress in the theory and treatment of CHD. However, prevention and treatment are equally important in CHD. The landmark INTERHEART study published in the Lancet in 2004 found that 90% of myocardial infarction was caused by nine controllable and predictive factors: dyslipidemia, smoking, diabetes, hypertension, abdominal obesity, psychosocial factors, inadequate daily intake of vegetables and fruits, lack of In recent years, studies have also found that inflammation, high homocysteine and high uric acid are associated with an increased risk of CHD.
