Correlation of microalbuminuria and fibrinogen to the severity of coronary artery lesions in patients with metabolic syndrome / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the correlation of microalbuminuria (MA) and fibrinogen (Fib) to the severity of coronary artery lesions in patients with metabolic syndrome (MS).</p><p><b>METHODS</b>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 score>20) 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.</p><p><b>RESULTS</b>The urinary albumin to creatinine ratio (ACR) and Fib were significantly different between the multivessel and non-multivessel disease groups (P<0.05), 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 (P<0.05), 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.</p><p><b>CONCLUSION</b>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.</p>
