ABSTRACT

ObjectiveTo investigate the effect of intensive dose atorvastatin on preventive contrast-induced nephropathy (CIN) in elder with coronary heart disease (CHD) after elective percutaneous coronary intervention (PCI).Methods110 subjects older than 60 who received elective PCI,were randomly divided into intensive dose atorvastatin group (the study group,n =50) and conventional treatment group (the control group,n =50).On the ba sis of the hydration therapy,the study group received atorvastatin and the control group received atorvastatin.Scr、β2- MG and liver function were checked for evidence of tubular or glomemlar damage before and after elective PCI were compared between the two groups.Ccr was calculated according to Cockcroft-Gault formula;The incidence of the major adverse cardiovascular events (MACE) and cytotoxicity and hepatotoxicity of rosuvastation were respectively recorded in 30 days follow-up period.ResultsCcr in the study group was significantly higher than that in the control group at day 1 [( 73.12 ± 16.89 ) ml/min vs ( 63.89 ± 18.42 ) ml/min,P =0.036],day 2 [( 65.32 ± 13.46 ) ml/min vs (55.63 ± 15.47 )mL/min,P =0.021] ;Blood β2-M in the study group was significantly lower than that in the control group at day 1 [( 2.44 ± 0.42 ) ml/min vs ( 2.69 ± 0.63 ) mL/min,P =0.009],day 3 ( 2.52 ± 0.46 ) mL/min vs (2.81 ±0.63) ml/min,P =0.011],day 3[(2.37 ±0.43) ml/min vs (2.54 ±0.65 ) ml/min,P =0.021].The incidence of CIN was lower in the study group than that in the control group(6％ vs 24％,P =0.012).During 30days clinical follow-up,the incidence of the MACE in the control group was more than the study group ( x2 =5.316,P =0.021).There was no significant difference between the two groups for the cytotoxicity and hepatotoxicity.ConclusionHigh dose atorvastatin may be more efficient in prevention CIN in elder before elective PCI and this higher dose may be safe to the elder.
