Abstract

OBJECTIVE:

The optimal medication therapies are recommended in patients with coronary artery disease even after the coronary revascularization. However, the information of optimal medical therapy in dialysis population is scant. We assessed the efficacy of statin on the clinical outcomes after Sirolimus-eluting stent (SES) implantation in patients with and without dialysis.

METHODS AND RESULTS:

We analyzed date from 843 consecutive patients who successfully treated with SES in our institution between August 2004 and November 2006. Among patients, 96 patients (11.4%) were undergoing dialysis. In non-dialysis patients, 405 patients (54%) were treated with statin at hospital discharge. In dialysis patients, only 16 patients (17%) were treated with statin. In non-dialysis patients, mortality rate was significantly lower in patients treated with statin than those without statin (4.4% vs. 13.9%, p<0.0001). While in dialysis patients, mortality rate was similar between patients treated with and without statin (56.3% vs. 57.6%, p=0.86). After adjusting for confounders, the hazard ratios for mortality were 0.39 (95% confidence interval (CI), 0.14-0.99; p=0.047) in non-dialysis patients and 1.79 (95% CI, 0.39-7.86; 0.45) for dialysis patients. The interaction probability between statin use and dialysis for mortality was 0.016.

CONCLUSION:

The use of statin may have beneficial effect on reducing mortality rate in patients after SES implantation in non-dialysis patients. However, such favorable effect was not observed in dialysis population.
