Abstract 2830: Survival of Dialysis Patients in the US after Surgical versus Percutaneous Coronary Intervention in the Drug-Eluting Stent Era
There are no published data on the comparative survival of dialysis patients undergoing surgical versus percutaneous coronary revascularization in the era of drug-eluting stents (DES). We searched the records of 1,698,706 pts in the United States Renal Data System database to identify 3376 dialysis pts having coronary artery bypass surgery without valvular surgery (CAB), non-drug eluting stents (non-DES), or DES in 2003. Long-term survival was estimated by Kaplan-Meier method and independent predictors of death were examined in a comorbidity-adjusted Cox model.
RESULTS: There were 1033 CAB pts, 1611 non-DES pts, and 732 DES pts. The entire cohort was 57% male, 63% white, 6% age 20–44, 39% age 45–64, 33% age 65–74, and 21% age 75+. Diabetes was the primary cause of renal failure in 58% and 6% received peritoneal dialysis. The Table⇓ shows survival and predictors of death (age 20–44, male, white, hemodialysis, no comorbidity, CAB is reference) with risk ratio (RR).
Conclusion: Our data suggest that the best one year survival of dialysis pts with surgical or percutaneous coronary revascularization procedures occurs with drug eluting stents.
