Abstrakt:	Objective: To determine the relationship between proprotein convertase subtilisin kexin 9 (PCSK9) levels and atheroma burden in Pakistanis presenting to an ambulatory centre with chest pain. Methods: A prospective matched case-control study of 400 patients selected for presence/absence of angiographic disease referred between 2001 and 2003. A comprehensive cardiovascular disease risk factor profile was assessed including demographics, environmental and biochemical risk factors including insulin resistance and PCSK-9 levels. Coronary atheroma burden was quantified by Gensini score. Results: In this population, PCSK-9 levels were weakly correlated (r = 0.23) with male gender (p = 0.06) and number of diabetes years (p = 0.09), and inversely with log10 of lipoprotein (a) concentration (p = 0.07) but not LDL-C. In multiple regression analysis, Gensini score was associated with age (p = 0.002), established angina (p = 0.001), duration of diabetes (p = 0.05), low HDL-C (p < 0.001), lipoprotein (a) (p = 0.01), creatinine (p < 0.001), C-Reactive Protein (p = 0.02) and PSCK-9 (p = 0.05) concentrations. PCSK9 added to the regression model. Neither total cholesterol nor LDL-C were significant risk factors in this study. Conclusions: Proprotein convertase subtilisin kexin 9 concentrations are correlated with atheroma burden in Indian Asian populations from the sub-continent, not taking statin therapy, independent of LDL-C or other CVD risk factors.
