[Efficacy of high dose atorvastatin on preventing contrast induced nephropathy in patients underwent coronary angiography].
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.


CONCLUSIONS
High dose atorvastatin use before angiography is superior than low dose atorvastatin on attenuating contrast induced renal dysfunction.
