Insights
Drug-eluting stents (DES) show better long-term outcomes than bare metal stents (BMS) for patients on hemodialysis (HD) undergoing percutaneous coronary intervention (PCI). DES reduces major adverse cardiac events and target lesion revascularization beyond one year.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Nephrology
Background:
- Coronary artery disease patients on hemodialysis (HD) face high restenosis rates after drug-eluting stent (DES) percutaneous coronary intervention (PCI).
- Limited data exists on the long-term outcomes of DES in HD patients.
Purpose of the Study:
- To compare the long-term clinical outcomes of DES versus bare metal stents (BMS) in HD patients undergoing PCI.
- To evaluate the effectiveness of DES in reducing restenosis and major adverse cardiac events in this high-risk population.
Main Methods:
- Retrospective comparison of 204 patients receiving BMS and 301 patients receiving DES for PCI.
- Kaplan-Meier analysis to assess long-term clinical outcomes, including target lesion revascularization (TLR) and major adverse cardiac events (MACE).
- Follow-up duration extended to 6 years for event rate analysis.
Main Results:
- DES group showed significantly lower 6-year MACE rates (42.5%) compared to the BMS group (58.0%, P=0.036).
- No significant difference in TLR at 1 year (17.8% vs. 21.3%, P=0.32).
- Beyond 1 year, DES significantly reduced TLR rates compared to BMS (16.4% vs. 30.9%, P=0.019).
Conclusions:
- DES implantation may be more effective than BMS for preventing medium to long-term TLR in HD patients.
- While short-term restenosis after DES in HD patients is common, long-term benefits in reducing revascularization are evident.
Background:
Percutaneous coronary intervention (PCI) with drug-eluting stent (DES) is widely performed in patients with coronary artery disease, but the high restenosis rate remains a major clinical problem after implantation of DES in patients on hemodialysis (HD). Until now, there are limited reports regarding the long-term clinical outcome after implantation of DES in this patient population.
Methods And Results:
We compared bare metal stent (BMS) and DES for long-term clinical outcomes, such as target lesion revascularization (TLR), in HD patients undergoing PCI. BMS and DES were implanted in 204 and 301 patients, respectively. Baseline and lesion characteristics were comparable between the 2 groups. By Kaplan-Meier analysis, event rates of major adverse cardiac events for 6 years were significantly lower in the DES group than in the BMS group (42.5% vs. 58.0%, P=0.036). Although there were no significant differences in TLR rates between patients treated with DES and those with BMS at 1 year after PCI (17.8% vs. 21.3%, P=0.32), patients treated with DES had significantly lower rates of TLR compared with those treated with BMS beyond the 1-year follow-up after PCI (16.4% vs. 30.9%, P=0.019).
Conclusions:
In patients on HD, implantation of DES might be more effective for preventing TLR in the medium to long follow-up period than BMS, although restenosis after PCI with DES is common in the short term.
