heal.abstractOBJECTIVE: To investigate the relationship between changes in high density lipoprotein cholesterol(HDL-C) levels after statin treatment and the risk for coronary heart disease (CHD)-related events in the secondary CHD prevention GREek Atorvastatin and Coronary heart disease Evaluation (GREACE) Study. These findings suggested that dose titration with atorvastatin (10-80 mg/day, mean 24 mg/day)achieves the National Cholesterol Educational Program treatment goals and significantly reduces morbidity and mortality, in comparison to usual care. METHODS: Analysis of variance was used to assess the effect of atorvastatin on HDL-C over time (up to 48 months) in 1600 CHD patients. The time-dependent multivariate Cox predictive model,involving backward stepwise logistic regression,was used to evaluate the relation between coronary events and HDL-C changes. RESULTS: The mean increase in HDL-C levels during the study was 7%. All doses of atorvastatin significantly increased HDL-C levels. Increases were greater in men (7.8 vs 6.1%; p = 0.02), in combined hyperlipidaemia (7.9 vs 6.4% for hypercholesterolaemia; p = 0.04), and in the lower baseline HDL-C quartile (9.2 vs 5.3%, 1st vs 4th quartile; p = 0.001). After adjustment for 24 predictors of coronary events, multivariate analysis revealed a Hazards Ratio of 0.85 (95% confidence interval 0.76-0.94; p = 0.002) for every 4 mg/dL(0.1 mmol/L) increase in HDL-C. CONCLUSIONS: There was a significant beneficial effect on HDL-C levels across the dose range of atorvastatin. Clinical outcomes in the structured care arm of GREACE were determined in part by the extent of atorvastatin-induced HDL-C increase. This effect was independent from benefit induced by low density lipoprotein cholesterol (LDL-C)reduction, suggesting that the CHD risk reduction associated with a rise in a low HDL-C at baseline remains significant under aggressive (-46%) LDL-C lowering conditions. However, the relationship between HDL-C and vascular risk may be weaker when LDL-C levels are aggressively lowered.en
