The study sought to evaluate the impact of diabetes mellitus on 3-year clinical outcome in patients undergoing drug-coated balloon (DCB) or drug-eluting stent (DES) treatment for de novo lesions.

For treatment of de novo coronary small vessel disease, DCBs are noninferior to DES.

In this prespecified analysis of a multicenter, randomized, noninferiority trial, including 758 patients with de novo lesions in coronary vessels <3 mm who were randomized 1:1 to DCB or DES and followed over 3 years for major adverse cardiac events (MACE) (cardiac death, nonfatal myocardial infarction [MI], and target vessel revascularization [TVR]), outcome was analyzed regarding the presence or absence of diabetes mellitus.

In nondiabetic patients (n = 506), rates of MACE (DCB 13.0% vs DES 11.5%; hazard ratio [HR]: 1.24; 95% confidence interval [CI]: 0.73-2.09; P = 0.43), cardiac death (2.8% vs 2.9%; HR: 0.97; 95% CI: 0.32-2.92; P = 0.96), nonfatal MI (5.1% vs 4.8%; HR: 1.00; 95% CI: 0.44-2.28; P = 0.99), and TVR (8.8% vs 6.1%; HR: 1.64; 95% CI: 0.83-3.25; P = 0.16) were similar. In diabetic patients (n = 252), rates of MACE (19.3% vs 22.2%; HR: 0.82; 95% CI: 0.45-1.48; P = 0.51), cardiac death (8.8% vs 5.9%; HR: 2.01; 95% CI: 0.76-5.31; P = 0.16), and nonfatal MI (7.1% vs 9.8%; HR: 0.55; 95% CI: 0.21-1.49; P = 0.24) were similar in DCB and DES. TVR was significantly lower with DCBs vs DES (9.1% vs 15.0%; HR: 0.40; 95% CI: 0.17-0.94; P = 0.036; P = 0.011 for interaction).

The rates of MACE are similar in DCBs and DES in de novo coronary lesions of diabetic and nondiabetic patients. In diabetic patients, need for TVR was significantly lower with DCB versus DES.
