High-density lipoprotein cholesterol (HDL-C)

High-density lipoproteins are mainly synthesized by the liver. It is composed of apolipoprotein, phospholipids, cholesterol and a small amount of fatty acids. High-density lipoprotein cholesterol (HDL-C): High-density lipoprotein cholesterol can be commonly understood as "good" cholesterol, anti-atherosclerotic cholesterol, because HDL-C reduces the risk of coronary heart disease. Basic Information Specialist classification: cardiovascular examination classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Common in cerebrovascular disease coronary heart disease, hypertriglyceridemia, liver damage such as acute and chronic hepatitis, cirrhosis, liver cancer diabetes, smoking, lack of exercise. Normal value: High-density lipoprotein cholesterol (male): 0.9-1.83mmol/L High-density lipoprotein cholesterol (female): 1.1-2.0mmol/L Above normal: Primary high HDL (familial hyperalpha-lipoproteinemia). negative: Positive: Tips: Before the blood draw, you should maintain the original regular diet and keep your weight constant. Normal value Male <40 years old 0.78 ~ 1.53mmol / L (30 ~ 59mg / dl); Female <40 years old 0.86 ~ 2.0mmol / L (33 ~ 77mg / dl). Clinical significance Increased is generally considered to be of no clinical significance and can be seen in primary hyper-HDLemia (familial hyper-alpha-lipoproteinemia) and found that there are many long-lived families in this group. Those who receive estrogen, insulin or certain drugs (such as niacin, vitamin E, heparin, etc.) can also be increased. Reduction: common in cerebrovascular disease, coronary heart disease, hypertriglyceridemia, liver damage, such as acute and chronic hepatitis, cirrhosis, liver cancer, diabetes, smoking, lack of exercise. Its reduction can be used as a risk indicator for coronary heart disease. High results may be diseases: obesity, obesity in the elderly, hyperlipidemia, metabolic syndrome considerations At the time of examination: the test should be carried out under the condition that the physiological and pathological conditions are relatively stable, and there should be no acute attack within 4-6 weeks. Before the test: Do not take certain drugs, such as birth control pills, certain antihypertensive drugs, etc., which may affect blood lipid changes, resulting in errors in testing. The first day of the inspection, after 8:00 pm, fasting, can not help but water. The original regular diet should be maintained before blood draw and the body weight should be kept constant. On the first night of the examination, you must rest well, entertain until midnight and even overnight. Check the blood pressure and blood lipids the next morning. Inspection process Inspection method: draw blood and check blood lipids. Not suitable for the crowd no. Adverse reactions and risks no.
