The difference between hypertension and coronary heart disease is that hypertension is a syndrome with symptoms of elevated blood pressure or cardiovascular risk factors, and it is an important cause and risk factor for cardiovascular disease, which can lead to the occurrence of coronary heart disease. The causes of hypertension are mainly related to genetic, environmental and other factors, with a tendency to run in families, environmental factors including mental stimulation, dietary factors, other factors including obesity and long-term use of birth control pills, etc. Coronary artery disease is atherosclerotic heart disease, which occurs when the blood vessels in the coronary arteries are hardened, resulting in plaque or narrowing, leading to myocardial ischemia and hypoxia. The risk factors for coronary heart disease are mainly age, gender, dyslipidemia, hypertension, smoking, diabetes, etc. Therefore, hypertension can exist alone or coronary heart disease can occur. Some patients with coronary heart disease are caused by hypertension, and some are not caused by hypertension, but by other factors.
