Optimising Percutaneous Coronary Interventions: The Impact of Stent Type and Diameter on Long-Term Clinical Outcomes in Large Coronary Arteries
MEDICINA-LITHUANIA(2024)
Abstract
Background and Objectives: Our study aimed to reveal the effect of using 4 mm bare-metal stents (BMS), 4 mm drug-eluting stents (DES), or 3 mm DES with 4 mm diameter balloon post-dilation strategies on long-term clinical outcomes and endpoints for large-diameter coronary artery percutaneous coronary intervention (PCI). Materials and Methods: In our study, patients who had undergone PCI were retrospectively screened between January 2014 and July 2020. The study included 350 patients and was divided into three groups; Group I (n = 134) included patients with direct 4.0 mm BMS implantation, Group II (n = 109) included patients with direct 4.0 DES implantation, and Group III (n = 107) included patients with 4mm NC post-dilatation after 3 mm DES implantation. Primary endpoints were determined as target lesion revascularisation, cardiac mortality, and myocardial infarction associated with the target vessel. Our secondary endpoint was all-cause mortality. Results: No differences were observed between the groups in terms of the baseline variables. Stent length was the highest in Group II and the shortest in Group III. There were no significant differences between the groups regarding major adverse cardiovascular events (MACE). Conclusions: Our study suggests that in percutaneous coronary interventions for non-complex lesions, there is no significant difference in MACE outcomes when directly implanting a 4 mm diameter DES, a 4 mm diameter BMS, or a 3 mm diameter DES, followed by post-dilation with an appropriately sized NC balloon when the target vessel diameter is in the range of 4 to 4.4 mm.
