OBJECTIVE: To compare the efficacy of high and low dose atorvastatin on preventing contrast induced nephropathy (CIN) in patients underwent diagnostic and therapeutic coronary intervention. METHODS: All patients received atorvastatin 10 mg/d on the basis of hydrated therapy (n = 100) and high dose group received additional atorvastatin 80 mg at 12 to 24 hours before procedure (n = 50). Scr, Ccr, blood beta(2)-M, urine NAG/Cr, and urine osmolality before and after the procedure were compared between the groups. RESULTS:Baseline demographic characteristics and nephropathy risk factors were similar between groups. Ccr was significantly reduced while blood beta(2)-M and uric NAG/Cr were significantly increased in low dose group (all P < 0.05). Blood beta(2)-M in the high dose group was significantly lower than that in the low dose group at day 1 [(2.35 +/- 0.52) mg/L vs. (2.67 +/- 0.64) mg/L, P = 0.008], day 3 [(2.49 +/- 0.55) mg/L vs. (2.80 +/- 0.64) mg/L, P = 0.011] and day 5 [(2.29 +/- 0.53) mg/L vs. (2.56 +/- 0.66) mg/L, P = 0.026] post-procedure respectively;urine NAG/Cr in the high dose group was also significantly lower than that in the low dose group at day 1 [(1.19 +/- 0.30) U/mmol vs. (1.46 +/- 0.34) U/mmol, P < 0.001], day 3 [(1.30 +/- 0.30) U/mmol vs. (1.59 +/- 0.33) U/mmol, P < 0.001], and day 5 [(1.10 +/- 0.30) U/mmol vs. (1.34 +/- 0.35) U/mmol, P = 0.001] post-procedure respectively;Ccr in the high dose group was significantly higher than that in the low dose group at day 1 [(73.69 +/- 20.99) ml/min vs. (65.19 +/- 18.72) ml/min, P = 0.035], day 3 [(64.04 +/- 15.82) ml/min vs. (56.79 +/- 14.50) ml/min, P = 0.019]post-procedure respectively. CONCLUSION: High dose atorvastatin use before angiography is superior than low dose atorvastatin on attenuating contrast induced renal dysfunction.
