Survival and Clinical Outcomes After Single-vessel Percutaneous Coronary Intervention Using Drug-eluting Stent: An Observational and Follow-up Study in a Tertiary Care Center in the Gangetic Plains of North India.

Introduction: Percutaneous coronary intervention (PCI) with drug-eluting stents (DES) has transformed the management of coronary artery disease (CAD), particularly for single-vessel disease (SVD), by reducing restenosis rates. However, long-term survival data following PCI in North Indian populations are limited. This study aimed to evaluate survival and clinical outcomes after PCI with DES and identify factors associated with mortality and adverse events, such as chest pain, dyspnea, and bleeding.
