[Correlation of microalbuminuria and fibrinogen to the severity of coronary artery lesions in patients with metabolic syndrome]

To investigate the correlation of microalbuminuria (MA) and fibrinogen (Fib) to the severity of coronary artery lesions in patients with metabolic syndrome (MS).Eighty-five patients with MS undergoing coronary artery angiography were divided, according to the number of vessels involved, into multivessel disease group and non-multivessel disease group, and also according to the modified Gensini score, into severe lesion (Gensini score20) and non-severe lesion group. The correlations of MA and Fib to the number of involved vessels and the severity of the lesions were analyzed.The urinary albumin to creatinine ratio (ACR) and Fib were significantly different between the multivessel and non-multivessel disease groups (P0.05), and were found to be positively correlated to the number of coronary artery lesion (r=0.378, P=0.000; r=0.327, P=0.002). ACR, Fib, sex, smoking history and HDL-C differed significantly between severe lesion and non-severe lesion groups (P0.05), and ACR and Fib showed positive correlations to the Gensini score (r=0.337, P=0.002; r=0.286, P=0.008). Logistic regression analysis identified ACR as an independent predictor of multivessel disease (B=2.655, P=0.000) and Gensini score (B=1.803, P=0.009), independent of sex, age, body mass index, smoking history, diabetes mellitus, LDL-C and HDL-C.MA and Fib are positively correlated to the severity of coronary artery lesion, and MA is an independent predictor of multivessel disease and Gensini score in patients with MS.
