مقایسه ارتباط سطح سرمی مارکرهای کلسترولی و لیپیدی در بررسی اختلالات لیپوپروتئینی در بیماران بستری در بیمارستان قلب دانشگاه علوم پزشکی مازندران

Background and purpose: Considering some restrictions of serum low density lipoprotein (LDL) as a marker for Coronary Artery Disease (CAD) risk factor and also the importance of apo B as a signinificant risk factor for CAD, measurement of non-HDL cholesterol has great value as a risk factor for CAD. Non-HDL cholesterol (total cholesterol minus HDL cholesterol) contains all lipoproteins including apo-lipoproteins. Materials and methods: In this study, 200 hospitalized patients (100 men and 100 women) with the diagnosis of CAD, documented by coronary angiography and 100 persons with normal angiography were recruited as case and control groups, respectively. Non-HDL cholesterol non-HDL-c was compared with LDL- cholesterol as a risk factor for CAD. Results: Measured levels of triglyceride, total cholesterol, lipoprotein atherogenic a (Lpa) and non-HDL-c were significantly higher than those in control group. HDL level was lower in patients group. Correlation analysis showed that non-HDL-c (and not LDL cholesterol) had a higher reverse correlation Triglyceride level. Conclusion: Measurement of non-HDL-c could be a good marker in atherogenic lipoproteins. Furthermore, due to potential power of its other atherogenic lipoproteins, it cannot be measured by LDL alone.
