According to the diagnostic criteria of hypertension, that is, systolic blood pressure ≥ 140 mmHg and (or) diastolic blood pressure ≥ 90 mmHg without taking anti-hypertensive drugs, the existing hypertensive patients in China have reached 1.6 billion, with more than 3 million new patients each year. In the population with hypertension, 50% to 60% have combined coronary heart disease, elevated blood pressure with impaired activity of the higher nerve centers, neuroendocrine disorders, and increased sensitivity of the cardiovascular system, including the coronary arteries, to adrenaline and catecholamines. These are both factors in the development of hypertension and pathological factors contributing to atherosclerosis. Hypertension can also damage the endothelium of the arteries, leading to the development of atherosclerosis and an increased risk of coronary heart disease. The higher the blood pressure level, the higher the incidence of cardiovascular disease. Hypertension and coronary heart disease are two independent and closely related cardiovascular diseases. (1) Both are common diseases in middle-aged and elderly people, and the prevalence increases with age. Both hypertension and coronary heart disease are known as “diseases of affluence”. Excessive smoking and alcohol, fatty food and lack of exercise are the same lifestyle of patients with both diseases. ③Overweight and obesity, genetic predisposition, hyperlipidemia, history of diabetes mellitus, inflammatory stimulation, and high plasma viscosity status are risk factors for the development of both diseases. ④The blood pressure level of hypertensive patients is closely related to the incidence of their coronary heart disease. Hypertension promotes the development of atherosclerosis, which in turn further increases blood pressure.
