Hyperlipidemia is an important risk factor that promotes hypertension, abnormal glucose tolerance, and diabetes. It can lead to serious diseases such as stroke, coronary artery disease, and myocardial infarction. In addition, hyperlipidemia can also lead to fatty liver, cirrhosis, cholelithiasis, pancreatitis, fundus bleeding, blindness, peripheral vascular disease, claudication, and hyperuricemia. Numerous research data show that hyperlipidemia is a risk factor for stroke, coronary heart disease, myocardial infarction, and sudden death. In addition, hyperlipidemia is also an important risk factor for promoting hypertension, abnormal glucose tolerance, and diabetes mellitus. Hyperlipidemia can also lead to fatty liver, liver cirrhosis, cholelithiasis, pancreatitis, fundus bleeding, blindness, peripheral vascular disease, claudication, and hyperuricemia. Therefore, it is necessary to pay high attention to the danger of hyperlipidemia, and actively prevent and treat it. Hyperlipidemia is the main risk factor causing atherosclerotic diseases in humans. Common atherosclerotic diseases include coronary heart disease (including myocardial infarction, angina pectoris and sudden death), cerebral infarction and peripheral vascular thromboembolic disease. These cardiovascular and cerebrovascular diseases have a high incidence, are hazardous, and progress aggressively, and their mortality accounts for about half of the total human mortality.
