More than 20 years have passed since the first company introduced drug-eluting stent (DES) in 2002, but competing companies still have improved their DESs under regulatory approval. This study aimed to investigate the criteria for interventional cardiologists performing percutaneous coronary intervention (PCI) in selecting a DES. From 10 April 2023, to 30 April 2023, 3,422 cardiologists were requested to complete a questionnaire, of whom 126 responded to the survey. Overall, 86.5% of the respondents used Xience cobalt-chromium everolimus-eluting stent (Xience) in &gt; 10% of PCI procedures. For Xience, brand loyalty and calcified lesions were important independent variables for the DES selection criteria. Ultimaster sirolimus-eluting stent (Ultimaster) was not affected by the clinical data delivered by the company, whereas the respondents were shown to seek support for their activities from the Ultimaster supplier. The relationship with the company and/or sales representative and the planned surgical procedure affected the use of Coroflex ISAR NEO sirolimus-eluting polymer-free stent. Patient background and lesion characteristics had little impact on the DES selection criteria, suggesting that DES performance has already reached its physical limitations to the extent that respondents may not value further improvements in performance or characteristics of DES.
