你的胆固醇水平意味着什么
了解你的胆固醇水平
Maintaining healthy cholesterol levels is a great way to keep your heart healthy. 它可以降低你得到的机会 心脏病 或者有一个 中风.
But first, you have to know your cholesterol numbers.
美国心脏协会建议
All adults age 20 or older should have their cholesterol 和 other traditional 风险因素 checked every four to six years as long as risk remains low. 如果某些因素使你处于高风险之中, 或者如果你已经有心脏病, your health care professional may ask you to check it more often. Work together to determine your risk for cardiovascular disease 和 中风 和 create a plan to reduce your risk.
您的测试结果:预览
Your test results will show your cholesterol levels in milligrams per deciliter of blood, or mg/dL. Total cholesterol 和 HDL (good) cholesterol are among numerous factors your health care professional can use to predict your lifetime or 10-year risk for a heart attack or 中风. Your health care professional will also consider other 风险因素, 比如年龄, 家族病史, 吸烟情况, 糖尿病 和 高血压.
Lipid profile or lipid panel is a blood test that will give you results for your 高密度脂蛋白胆固醇, 低密度脂蛋白胆固醇, 甘油三酯和总血胆固醇.

高密度脂蛋白胆固醇
高密度脂蛋白胆固醇 is called “good” cholesterol. A healthy HDL-cholesterol level may help protect against heart attack 和 中风. Your health care professional will evaluate your HDL 和 other cholesterol levels 和 other factors to assess your risk for heart attack or 中风.
People with high blood triglycerides may also have lower levels of HDL. 遗传因素, 糖尿病, 吸烟, being overweight 和 being sedentary can all lower 高密度脂蛋白胆固醇. Men between ages 20 和 39 tend to have higher levels of 高密度脂蛋白胆固醇 than women do, but women’s risk increases after menopause.
低密度脂蛋白胆固醇
Since LDL is the bad kind of cholesterol, a low LDL level is considered good for your heart health.
LDL levels are one factor among many to consider when evaluating cardiovascular risk. 和你的健康护理专家谈谈 about your 低密度脂蛋白胆固醇 level as well as other factors that impact your cardiovascular health.
富含饱和脂肪和反式脂肪的饮食 脂肪 is unhealthy because it tends to raise 低密度脂蛋白胆固醇 levels.
我的低密度脂蛋白能降到多低?
- Various research studies on LDL have shown “lower is better.”
- While there is no ideal target blood level for LDL-C, 2018年指南承认, 原则上, “越低越好”.“研究表明 optimal total cholesterol level is about 150 mg/dL, LDL-C低于100mg /dL, 和 adults with LDL-C in this level have lower rates of 心脏病 和 中风.
- 和你的健康护理专家谈谈. If you’re healthy, aim for an LDL below 100 mg/dL. 另外, for individuals with a history of heart attack or 中风 和 are already on a cholesterol-lowering medication, 你的医生的目标是 at least 50% reduction in your LDL-C level to 70 mg/dL or lower.

甘油三酸酯
甘油三酸酯 are the most common type of 脂肪 in your body. They come from food, 和 your body also makes them.
People with high triglycerides may also have a high total cholesterol level, including a high 低密度脂蛋白胆固醇 level 和 a low 高密度脂蛋白胆固醇 level. 很多人 代谢综合征 or 糖尿病 also have high triglyceride levels.
Factors that can contribute to elevated triglyceride levels include:
- 超重或肥胖
- 胰岛素抵抗或代谢综合征
- 糖尿病
- 饮酒:饮酒，尤指过量
- Excess sugar intake, especially from sugary drinks
- 食用加工食品
- 高饱和脂肪摄入量
- 甲状腺功能减退
- 慢性肾病
- 缺乏身体活动
- 胰岛素抵抗或代谢综合征
- Pregnancy, especially in the third trimester
- Inflammatory diseases, such as rheumatoid arthritis, systemic lupus erythematosus
Some medications may also increase triglycerides.
总血胆固醇
This part of your test results is a composite of different measurements. Your total blood cholesterol is calculated by adding your HDL 和 低密度脂蛋白胆固醇 levels, 加上甘油三酯水平的20%.
While cholesterol levels above “normal ranges” are important in your overall cardiovascular risk, 比如高密度脂蛋白和低密度脂蛋白胆固醇水平, your total blood cholesterol level should be considered in context with your other known 风险因素.
Your health care professional can recommend treatment approaches based on your risk.
