Abstract：Objective To investigate the relationship between microalbuminuria to estimated glomerular filtration rate (mALB/GFR) ratio and incidence of contrast induced nephropathy (CIN) after underwent percutaneous coronary intervention (PCI). Between March 2010 to August 2011, a total of 137 patients who underwent PCI were selected. Anthropometric measures, lipid profiles, fasting blood glucose, CRP, base creatinine and microalbuminuria were measured before operation. Glomerular filtration rate was calculated by MDRD formula. Contrast volume (CV) was recorded after the operation for each patient. Serum creatinine was measured 24 h, 48 h, 72 h after operation, respectively. CIN was defined as an increase in serum creatinine levels of 25% or 44 μmol/L or more from baseline within 72 h after PCI. All patients were divided into group A (CIN group) and group B (No CIN group). Results Eighteen (13.1%) patients developed CIN(group A). The others were group B (no CIN group). The level of CRP, base creatinine, microalbuminuria and mALB/GFR in group A were significantly higher than that in group B ( P < 0 . 01 ) . GFR in group A was lower than that in group B (P < 0.05). Logistic regression analysis indicated that the level of base creatinine , microalbuminuria GFR and mALB/GFR were independent risk factors of CIN occurrence (P < 0.05). The receiver-operator characteristic curve analysis indicated that a mALB/ GFR ratio of 1.17 was a fair discriminator for CIN,and sensitivity were 94.1%, specifity were 72.5%. Conclusion A mALB/ GFR ratio was a independent predictor of CIN after PCI.
