ABSTRACT: Background
Data on the safety and efficacy of drug-coated balloon (DCB) compared to drug-eluting stent (DES) in patients with chronic kidney disease (CKD) are scarce, particularly at long term. This pre-specified analysis aimed to investigate the 3-year efficacy and safety of DCB versus DES for small coronary artery disease (< 3 mm) according to renal function at baseline.Methods
BASKET-SMALL-2 was a large multi-center, randomized, controlled trial that tested the efficacy and safety of DCBs (n = 382) against DESs (n = 376) in small vessel disease. CKD was defined as eGFR < 60 ml/min/1.73m2. The primary endpoint was the composite of cardiac death, non-fatal myocardial infarction, and target vessel revascularization (MACE) during 3 years.Results
A total of 174/758 (23%) patients had CKD, out of which 91 were randomized to DCB and 83 to DES implantation. The primary efficacy outcome during 3 years was similar in both, DCB and DES patients (HR 0.98; 95%-CI 0.67-1.44; p = 0.937) and patients with and without CKD (HR 1.18; 95%-CI 0.76-1.83; p = 0.462), respectively. Rates of cardiac death and all-cause death were significantly higher among patients with CKD but not affected by treatment with DCB or DES. Major bleeding events were lower in the DCB when compared to the DES group (12 vs. 3, HR 0.26; 95%-CI 0.07-0.92; p = 0.037) and not influenced by presence of CKD.Conclusions
The long-term efficacy and safety of DCB was similar in patients with and without CKD. The use of DCB was associated with significantly fewer major bleeding events (NCT01574534).
