HD Patients' Cardiovascular Risks Not Lowered by Statin

Rosuvastatin therapy lowers LDL in hemodialysis (HD) patients but has no significant effect on cardiovascular events, researchers reported in The New England Journal of Medicine (2009;360:1395-1407).

The finding is based on findings from A Study to Evaluate the Use of Rosuvastatin in Subjects on Regular Hemodialysis: An Assessment of Survival and Cardiovascular Events (AURORA), a multicenter, randomized, double-blind, prospective trial. Participants comprised 2,776 HD patients aged 50-80 years randomly assigned to receive rosuvastatin 10 mg daily or placebo.

After three months, the mean reduction in LDL levels was 43% in patients receiving rosuvastatin, from a mean baseline level of 100 mg/dL.

During a median follow-up of 3.8 years, 396 rosuvastatin-treated subjects and 408 placebo recipients reached the composite primary end point of death from cardiovascular causes, nonfatal MI, and nonfatal stroke (9.2 and 9.5 events per 100 patient-years, respectively, a nonsignificant difference between groups). Rosuvastatin also had no significant effect on all-cause mortality.
