Research status and trends of drug-coated balloons in coronary artery disease: a bibliometric analysis

DCB are now established as a standard of care for ISR (Class IA recommendation), with accumulating evidence supporting their efficacy and safety in small-vessel coronary disease. However, their application in complex lesions requires further validation through multicenter randomized controlled trials. Future research should focus on optimizing drug coating technologies, refining imaging-guided strategies, exploring new anti-proliferative drugs, and establishing more precise eligibility criteria for treatment.
