In clinical practice, hyperlipidemia can be diagnosed based on medical history, clinical manifestations and relevant examinations, and its diagnosis is based on the following.
1.Identification according to medical history: for those who have a family history of hyperlipidemia or a history of dyslipidemia and poor dietary habits such as high-fat diet, the presence of hyperlipidemia can be considered with emphasis.
2, self-judgment according to symptoms: early symptoms of hyperlipidemia are not obvious, symptoms are mostly caused by the complications it causes, such as dizziness, yellow warts in the eyes, dark skin spots, blurred vision and other manifestations, should promptly seek medical attention to clarify the diagnosis.
3.Confirm the diagnosis according to blood lipid examination.
(1) Four tests of blood lipids: including triglycerides, total cholesterol, HDL cholesterol and LDL cholesterol.
(2) Determination of the presence of celiac particles in the plasma: a simple method can be used, i.e. placing the plasma in a refrigerator at 4°C overnight and then observing whether the plasma has a “cream-like” top layer.
(3) Lipoprotein test: The value of HDL and LDL can be measured to determine whether the patient is suffering from hyperlipidemia.
I. Diagnostic criteria of hyperlipidemia
The diagnostic criteria of hyperlipidemia vary according to its classification, as follows.
Second, who needs to focus on blood lipid examination
Blood lipid is a routine examination item, but the following people need to focus on blood lipid examination.
1, people with a history of cardiovascular disease: including patients with coronary heart disease, acute myocardial infarction, unstable angina, stable angina, revascularization, stroke and peripheral vascular disease.
2. people with risk factors for cardiovascular disease: such as hypertension, obesity, diabetes, smoking and alcohol abuse
3, family history: parents or siblings with a history of early onset of cardiovascular disease, and the age of onset <55 years for men and <65 years for women, or those with familial dyslipidemia.
4.Other: men over 40 years old, post-menopausal women and those with poor living habits and those with skin yellow tumors.
Third, how often do you need to check blood lipids
1.Healthy adults over 20 years old: fasting blood lipid examination at least once every 5 years.
2.Men over 40 years old and menopausal women: have their blood lipids checked at least once a year.
3.Combined ischemic cardiovascular disease and its high-risk groups: review lipids every 3-6 months.
4.People who use lipid-lowering drugs: measured every 1-2 months after the first dose, and then extended to every 2-3 months, and can be measured every 6-12 months after the control reaches the standard.
Fourth, what should be noted before the blood lipid test
1.After 8:00 p.m. the day before the test, you should fast and drink a small amount of plain water.
2, three days before the test should avoid high-fat diet.
3, 24 hours before the test should not be strenuous exercise, should not drink alcohol.
4.Medications affecting lipid levels should be stopped for several days or weeks before blood collection, excluding lipid-lowering drugs being taken.
5.Avoid acute infection, trauma, fever, pregnancy, female menstruation, etc. to measure blood lipids.
