Comparing drug-coated balloons and drug-eluting stents for patients with high bleeding risk and chronic coronary syndrome

Discontinuation of Antiplatelet Agent After Drug-Coated Balloon Angioplasty in Stabilized Patients With High Bleeding Risk and Coronary Artery Disease

Not applicable Interventional Samsung Medical Center · NCT06742931

This study is testing whether using drug-coated balloons instead of drug-eluting stents can help patients with chronic coronary syndrome who are at high risk for bleeding, while also looking at how long they need to take blood-thinning medicine after the procedure.

What this trial studies

This clinical trial is a prospective, multi-center, open-label, randomized controlled trial that aims to compare the clinical outcomes of patients with chronic coronary syndrome who are treated with drug-coated balloon (DCB) angioplasty versus those treated with drug-eluting stents (DES). The study focuses on patients at high bleeding risk (HBR) and evaluates the effects of continuing or discontinuing antiplatelet therapy after the procedure. By assessing the need for dual antiplatelet therapy (DAPT) in these patients, the trial seeks to determine if DCB can provide a safer alternative with shorter therapy duration. The primary goal is to analyze the incidence of clinical events over a year following the intervention.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 19 and older with chronic coronary syndrome and at least one de novo coronary lesion, who also meet the criteria for high bleeding risk.

Not a fit: Patients who do not have chronic coronary syndrome or those who do not meet the high bleeding risk criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer treatment option for patients with chronic coronary syndrome who are at high risk of bleeding.

How similar studies have performed: Other studies have shown promising results with drug-coated balloons in similar patient populations, indicating potential for success in this approach.
