In China, the population of hyperlipidemia is very large, with as many as 200 million adults over the age of 18, yet the awareness rate is very low, with 28% among men and only 21% among women, so it is imperative to actively conduct lipid screening. So, what should you know about lipid screening? First, who should have their blood lipids checked? For people at high risk of high blood lipids, we recommend that they should have their blood lipids checked once every six months to once a year. High-risk groups include: patients with coronary heart disease, diabetes, hypertension, stroke, men over 40, women going through menopause, smoking, obesity, and patients with coronary heart disease or hyperlipidemia in the family. For adults over 20 years of age, we recommend that fasting lipids be measured at least once every 5 years for non-high risk patients. Second, how to prepare before blood lipid examination 1. Fasting after 8:00 pm the night before the examination, not water, should be fasted for 10-12 hours after the morning intravenous blood draw 2. 2 weeks before the blood test should maintain the original diet and keep the weight stable 3. Rest well the night before the examination, rest for 5 minutes before the blood draw 4. It is best to stop taking drugs affecting blood lipids for 2-4 weeks before ischemia, such as birth control pills, certain antihypertensive drugs, hormones, etc. 5, There should be no acute illness, such as fever or acute infection, within 4-6 weeks prior to the blood draw. 6. There should be at least two laboratory results confirming abnormal blood lipids, and the interval between the two tests should not exceed 3 weeks. At present, only 4 indicators are needed to guide the treatment of dyslipidemia, so you can do these 4 lipid tests: Low-density lipoprotein cholesterol (LDL-c): bad cholesterol, which can cause many cardiovascular diseases High-density lipoprotein cholesterol (HDL-c): good cholesterol, which can send the excess cholesterol back to the liver for metabolism and prevent cardiovascular events Total cholesterol (TC): is the sum of all cholesterol in the blood, and to some extent reflects LDL-c levels Triglycerides (TG): there is no conclusive evidence that triglycerides are associated with cardiovascular events, but high TG can induce acute pancreatitis. What to do if you have high blood lipids? Lifestyle improvement + medication, two-pronged approach to lower blood lipids! Lifestyle improvement: reasonable diet, proper exercise, optimism, quit smoking and limit alcohol Medication: statin is preferred, lower bad cholesterol, stabilize/’reverse plaque, prevent cardiovascular disease.
