Objective

To investigate the efficacy and long-term clinical benefits of DES for dialysis patients.

Background

It is unclear whether percutaneous coronary intervention PCI with drug-eluting stent DES implantation is associated with lower rates of major adverse cardiovascular events MACE or mortality compared to bare-metal stents BMS.

Methods

From a nationwide cohort selected from Taiwan’s National Health Insurance Research Database, we enrolled 2,835 dialysis patients who were hospitalized for PCI treatment with stent implantation from Dec 1, 2006. Follow-up was from the date of index hospitalization for PCI until the first MACE, date of death, or December 31, 2011, whichever came first.

Results

A total of 738 patients 26.0% had DES implanted, and 2,097 74% had BMS implanted. The medium time to the first MACE was 0.53 years interquartile range: 0.89 years; range: 0–4.62 years. At 1-year follow-up, patients treated with BMS had significantly, non-fatal myocardial infarction MI, all-cause mortality, and composite MACE compared to those treated with DES. The overall repeat revascularization with coronary artery bypass graft CABG, non-fatal MI, all-cause mortality, and composite MACE were significantly lower in patients treated with DES than those treated with BMS. Multivariate cox regression analysis showed that older age, history of diabetes, history of heart failure, history of stroke, and DES vs. BMS were independent significant predictors of MACE.

Conclusions

DES implantation conferred survival benefits in dialysis patients compared with BMS implantation.
