大剂量阿托伐他汀预防对比剂肾病

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 nag at 12 to 24 hours before procedure (n =50). Scr, Ccr, blood β2-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. Cer was significantly reduced while blood β2-M and uric NAG/Cr were significantly increased in low dose group (all P ＜ 0.05) . Blood β2-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) nag/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;Cer 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.
