Background:
Endothelial progenitor cells (EPCs) capturing stents were developed to enhance endothelial repair and reduce the risk of stent thrombosis, addressing limitations of Sirolimus-Eluting Stents (SES). This study aims to compare the safety and efficacy of EPC stents versus SES in patients undergoing percutaneous coronary intervention (PCI).
Methods:
We performed a meta-analysis following PRISMA guidelines in patients undergoing PCI treated with Sirolimus eluting stent (SES) vs the use of EPC stents and recognized 8 clinical trials with patients undergoing PCI and reporting outcomes such as Target Lesion Failure (TLF), stent thrombosis, and revascularisation. Relative risks were calculated using a random effects model and heterogeneity was assessed with I^2 statistics.
Results:
The EPC group showed higher incidence of TLF (RR = 1.28), MI(RR = 1.10), and cardiac death (RR = 1.19) compared to SES, though these differences were not statistically significant. Revascularisation rates were significantly higher in EPC group with TVR (RR = 1.60) and TLR(RR = 2.20) while stent thrombosis was lower (RR = 0.93).
Conclusion:
The results of this EPC study reveals that while EPC stents show promise in revascularisation and lowering stent thrombosis, they are also associated with higher incidence of adverse events. The utility of EPC, especially vast reendothelialization, may have niche applications but their full potential can be realized with more rigorous trials as a clear advantage over SES remains lacking.
