Outcomes with Drug-Coated Balloons in Percutaneous Coronary Intervention in Diabetic Patients (original) (raw)

Cardiovascular Revascularization Medicine, 2019

Abstract

BACKGROUND Percutaneous coronary intervention (PCI) in patients with diabetes mellitus (DM) remains associated with inferior clinical outcomes and an increased risk of restenosis compared with non-diabetics even in the era of drug-eluting stents (DES). The outcomes with drug-coated balloons (DCBs) in diabetic patients have received limited study. METHODS We performed a meta-analysis of all studies published between January 2000 and January 2019 reporting the outcomes with DCB vs. DES after PCI of de-novo coronary lesions in diabetic patients. Outcomes included major adverse cardiovascular events (MACE), target lesion revascularization (TLR), binary restenosis by quantitative coronary angiography (QCA), and late lumen loss (LLL). RESULTS Three studies with 378 patients (440 lesions) were included in the meta-analysis. During 17.3 ± 11.3 months follow-up, DCB were associated with a similar risk of MACE (OR: 0.63, 95% CI [0.36, 1.12], p = 0.11), TLR (OR: 0.51, 95% CI [0.25, 1.06] p = 0.07), binary restenosis (OR: 0.42, 95% CI [0.09, 1.92], p = 0.26), and LLL (mean difference: -0.13 mm, 95% CI [-0.41, 0.14], p = 0.34) compared with DES. CONCLUSION In diabetic patients with de-novo coronary lesions undergoing PCI, DCBs are associated with similar outcomes compared with first-generation DES, with a signal toward potential benefit in lowering target lesion revascularization. Further randomized studies are needed to compare the newer-generation DCBs and DES in this setting.
