Backround: To evaluate the diagnostic value of major and other risk factors as lipoprotein (Lp) (a), homocysteine (Hcy), high sensitive C-reactive protein (hs-CRP) and fibrinogen in CAD patients. Methods: A total of 223 subjects (118 patients and 105 controls) were included in the study according to their coronary angiographic results. Lipoprotein (a), Hcy, hs-CRP and fibrinogen levels were measured using immunoturbidometric, florescent polarization immunoassay and nefelometric methods, respectively. Fasting glucose and lipid parameters, except low density lipoprotein cholesterol (LDL-C), are determined by enzymatic colorimetric methods and the LDL-C levels were calculated by the Fridewald formula. Results: Logistic regression analysis showed that when the biochemical variables in placed in a model, the most important variables were Lp (a), Hcy, hs-CRP and fibrinogen. We showed that each unit of Lp (a), Hcy, hs-CRP and fibrinogen increases the risk of CAD 1.029, 1.177, 1.027 and 1.013 fold, respectively. Among these, fibrinogen level was the most sensitive and efficient parameter in prediction of CAD. Conclusion: Although Lp (a), Hcy, hs-CRP and fibrinogen are independent risk factors for CAD, fibrinogen was the most important one. Fibrinogen can be used as a reliable risk factor for CAD in clinical practice. [Cukurova Med J 2013; 38(4.000): 559-566] |
