Abstract
Objective: Early cessation of dual antiplatelet therapy (DAPT) is related to stent thrombosis (ST). The use of second-generation everolimus- and zotarolimus-eluting stents is associated with low restenosis rates and short duration of clopidogrel usage. Non-cardiac surgery in recently stent-implanted patients is associated with major adverse cardiac events (MACEs). Chronic renal failure patients awaiting renal transplantation may also undergo coronary stent implantation prior to surgery. Here we aimed to investigate the safety of early (3 months) DAPT interruption in second-generation drug-eluting stent (DES)-implanted renal transplant recipients.Methods: In total, 106 previously stent-implanted chronic renal failure patients who underwent renal transplantation were retrospectively enrolled. Three groups were formed according to stent type and the duration of DAPT: early-interruption (3 months from DES implantation), lateinterruption (3–12 months from DES implantation), and bare-metal stent (BMS; at least 1 month from BMS implantation) groups.Results: Comparison among BMS, DES-early and DES-late groups indicated no difference in ST, myocardial infarction, death, and MACEs. In addition, no difference was observed in ST (p=0.998), myocardial infarction (p=0.998), death (p=0.999), and MACEs (p=0.998) between DES-early and DES-late groups. Conclusion: Early (3 months) interruption of antiplatelet treatment with second-generation stents before renal transplantation seems to be safe and does not lead to increase in the occurrence of ST and MACEs
