The risk factors for coronary artery disease are usually very high in people with three highs, namely high blood pressure, high blood sugar and high blood lipids. If this is accompanied by high blood pressure, the pressure on the endothelium of the coronary artery will be aggravated, and the luminal plaque will rupture, leading to acute myocardial infarction. At the same time, if the patient has high blood sugar, it will further aggravate the risk factors of coronary heart disease, so effective control of blood pressure, blood sugar and blood lipids can control coronary heart disease.
