Abstract

Background: When the pro-healing COMBO stent is used, a short duration of dual-antiplatelet therapy (DAPT) might be safe. However, no cases have been described of patients with short duration of DAPT after COMBO stent placement. Methods and results: We investigate clinical outcomes at 1 year after early discontinuation of DAPT in patients participating in the REMEDEE Registry. This is a prospective, multicentre, European, all-comers registry with a 1000 patients treated with COMBO stent. Target lesion failure (TLF), a composite of target vessel-myocardial infarction (tv-MI), cardiac death and target lesion revascularization, and the occurrence of stent thrombosis (ST) in relation with DAPT cessation before 30 and 180 days of follow-up is evaluated. At 30 days follow-up 48 patients were not on DAPT, at 180 days follow-up of 78 patients had no DAPT. Patients with DAPT discontinuation were older, had overall lower left ventricle ejection fraction and more frequent chronic renal failure. No TLF and especially no stent thrombosis were observed in these patients. Conclusions: Discontinuation of DAPT within 6 months after COMBO stent placement did not influence the rate of TLF up to 1-year follow-up. Large randomized trials are needed to confirm the safety of short duration of DAPT after COMBO stent placement.
