1. Who needs a blood lipid test?
People with coronary heart disease, cerebrovascular disease or peripheral atherosclerosis. Have hypertension, diabetes, obesity, smokers. Family history of coronary heart disease or arteriosclerosis, especially immediate family members (including parents, siblings, children, grandparents, etc.). ) have premature coronary heart disease (before the age of 55 for men and before the age of 65 for women) or other vascular sclerosis diseases. People with xanthoma of the skin. People with familial hyperlipidemia. Dyslipidemia can sometimes show some nonspecific symptoms, such as dizziness, headache, numbness of hands and feet, etc. But more often than not, it was discovered because of physical examination or hospitalization for other diseases. Therefore, even if there are no symptoms, people who meet the above conditions should routinely check their blood lipids in order to find and find abnormal blood lipids in time. In addition, it is suggested that adults over the age of 20 should check their blood lipids 1 time at least every five years. Men over 40 years old and postmenopausal women should have an annual blood lipid examination. For patients with ischemic cardiovascular and cerebrovascular diseases (angina pectoris, myocardial infarction, stroke, transient ischemic attack, etc. ) and its high-risk population, 1 time should be measured every 3~6 months.
2. The higher the total cholesterol, the more serious the blood vessel blockage.
Total cholesterol refers to the sum of cholesterol contained in various lipoproteins in blood. The optimal level of serum total cholesterol is less than 5.2 mmol/L, and the risk threshold is 5.2-6.2 mmol/L. The simple increase of serum total cholesterol is hypercholesterolemia, which is one of the main risk factors of atherosclerosis. The higher the serum cholesterol level, the earlier the onset of coronary heart disease.
The increase of total cholesterol is also seen in patients with fatty liver, liver tumor and some extrahepatic diseases. Extrahepatic diseases include hypothyroidism, diabetes, atherosclerosis, nephrotic syndrome, common bile duct obstruction, myxedema and so on. Cholesterol reduction is seen in severe liver parenchymal lesions, hyperthyroidism, pernicious anemia and malnutrition.
3. The higher the HDL, the safer the cardiovascular system.
High density lipoprotein is a protective factor against atherosclerosis, commonly known as? Good cholesterol? The level of plasma high density lipoprotein is negatively correlated with the onset of coronary heart disease. Low high density lipoprotein is a powerful predictor of coronary heart disease, so it is beneficial to increase it. When suffering from chronic liver disease, liver cirrhosis, diabetes, coronary heart disease, chronic renal insufficiency and other diseases, high density lipoprotein will decrease.
The National Cholesterol Education Program Adult Treatment Expert Group pointed out that high-density lipoprotein
It has been reported that the risk of coronary heart disease decreases by 2% ~ 3% with the increase of 10 mg/dl (0.26 mmol/l). From the point of view of clinical prevention and treatment of atherosclerotic coronary heart disease. According to whether the level of high density lipoprotein is normal or not, different prevention and treatment methods can be adopted for atherosclerotic coronary heart disease.
4. The higher the 4.LDL, the faster the arteriosclerosis.
Low density lipoprotein, also known as atherosclerotic lipoprotein, commonly known as? Bad cholesterol? , reducing anti-beneficial. Low density lipoprotein? 4. 1 mmol/L is one of the high-risk factors of coronary heart disease, and low-density fat eggs are derived from.
5. The higher the triglyceride, the higher the risk of coronary heart disease.
The increase of triglycerides, also known as fat, is also a risk factor for coronary heart disease. Clinically, most hypertriglyceridemia is mainly seen in liver diseases such as metabolic syndrome, diabetes, nephrotic syndrome and fatty liver. Abnormal increase of triglyceride in congenital lipoprotein lipase deficiency. The decrease of triglyceride is seen in hypothyroidism, adrenal cortex hypofunction and severe liver function damage.
6. How to get accurate blood lipid test results?
Blood lipid testing requires patients to have an empty stomach to avoid the influence of eating on blood lipid concentration. It is generally believed that the detection of total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol is less affected by diet, and can be detected in non-fasting state during follow-up. Eating has a great influence on the detection of triglycerides, and it is required to be tested after fasting 12~ 14 hours.
If your blood lipid test results exceed the standard, first of all, think about whether you draw blood on an empty stomach (more than 8 hours on an empty stomach). Secondly, check whether you have eaten or drunk the day before. If neither. I suggest that you adjust your work rhythm, reduce drinking and high-fat diet intake when socializing, strengthen exercise, eat lightly, review after 2 months, and further receive lipid-lowering treatment if necessary.
