Background: Little is known about statins in the prevention of dyslipidoemia induced renal function decline. The secondary coronary heart disease (CHD) prevention GREACE study suggested that dose titration with atorvastatin (10-80 mg/day, mean dose 24 mg/day) achieves the national cholesterol educational programme treatment goals and significantly reduces morbidity and mortality, compared with usual care. Aims: To report the effect of statin on renal function compared with untreated dyslipidaemia in both treatment groups. Methods/Results: All patients had plasma creatinine values within the reference range < 115 μmol/litre (13 mg/litre). The on study creatinine clearance (CrCI), as estimated (for up to 48 months) by the Cockroft- Gault formula, was compared within and between treatment groups using analysis of variance to assess differences over time. Patients from both groups not treated with statins (704) showed a 5.2% decrease in CrC (p<0.0001). Usual care patients on various statins (97) had a 4.9% increase in CrC (p = 0.003). Structured care patients on atorvastatin (783) had a 1 2% increase in CrCI (p < 0.0001). This effect was more prominent in the lower two quartiles of baseline CrC1 and with higher atorvastatin doses. After adjustment for 25 predictors of all CHD related events, multivariate analysis revealed a hazards ratio of 0.84 (confidence interval 0.73 to 0.95; p = 0.003) with every 5% increase in CrCI. Conclusions: In untreated dyslipidaemic patients with CHD and normal renal function at baseline, CrCl declines over a period of three years. Statin treatment prevents this decline and significantly improves renal function, potentially offsetting an additional factor associated with CHD risk. [ABSTRACT FROM AUTHOR] |
