Background: Percutaneous coronary intervention is widely used in the treatment of coronary artery disease. Long coronary lesions frequently require implantation of more than one stent, which may lead to overlapping stent segments. Increased metal burden and altered vascular healing in the overlapping region may contribute to adverse clinical outcomes.

Methods: This study evaluated patients who underwent percutaneous coronary intervention for long coronary lesions. Patients were divided into two groups according to the stenting strategy: overlapping stent implantation and single long stent implantation. Clinical outcomes including major adverse cardiovascular events, myocardial infarction, target lesion revascularization, stent thrombosis, and mortality were assessed during follow-up.

Results: Patients treated with overlapping stents demonstrated numerically higher rates of adverse clinical events without reaching statistical significance. In particular, target lesion revascularization and stent thrombosis were observed more frequently in the overlapping stent group.

Conclusion: Overlapping stent implantation in the treatment of long coronary lesions may be associated with a trend toward increased risk of adverse cardiovascular events. Careful selection of stenting strategy may help improve clinical outcomes in these patients.
