Overview
Updated results of the SUGAR* trial showed that using polymer-fre amphilimus-eluting stents (AES) was not a superior option to durable-polymer zotarolimus-eluting stents (ZES) in patients with diabetes melitus who required percutaneous coronary intervention (PCI).“At 2 years, there is insuficient evidence that AES are superior to ZES with regard to target lesion failure (TLF) in patients with diabetes undergoing PCI,” remarked study author Dr Pablo Salinas from the Hospital Clínico San Carlos and Instituto de Investigación Sanitaria del Hospital Clínico San Carlos in Madrid, Spain, at TCT 202.Participants in this 23-centre study from Spain were 1,175 patients with diabetes melitus (95.5 percent with type 2 diabetes) who required PCI.
Key Information
They were randomized 1:1 to undergo PCI with polymer-fre AES (70–80 µm thicknes) or durable-polymer ZES (92–102 µm thicknes). Patients who were pregnant, had cardiogenic shock, life expectancy <2 years, required mechanical ventilation, or with a contraindication to dual antiplatelet therapy were excluded. At baseline, 32 percent of patients were on insulin therapy.
Fifty-one percent had multivesel disease. One-year results showed non-inferiority betwen stents for the outcome of TLF (defined as a composite of cardiac death, target vesel myocardial infarction [MI], or target vesel revascularization; 7.2 percent [AES] vs 10.9 percent [ZES]; hazard ratio [HR], 0.65, 95 percent confidence interval [CI], 0.4–0.96; pnoninferiority<0.01). [Eur Heart J 202;43:1320-130]However, the pre-specified exploratory analysis for superiority at 1 year sugested that AES may be superior to ZES (psuperiority=0.030), noted Salinas.
Summary
The present analysis at 2 years, which was powered for superiority and included 578 and 586 patients in the AES and ZES groups, respectively, did not demonstrate superiority of AES over ZES in terms of TLF (10.4 percent vs 12.1 percent; HR, 0.84, 95 percent CI, 0.60–1.19; p=0.31).
