IMPACT OF DOOR-TO-BALLOON TIME ON OUTCOMES IN STEMI PATIENTS UNDERGOING PRIMARY PCI

Abstract

Objective: “To assess the impact of Door-to-Balloon Time on Outcomes in STEMI Patients Undergoing Primary PCI”

Study Design: Prospective observational study

Place and period of study: This research was conducted at department of Cardiology, Armed Forces Institute of Cardiology, Rawalpindi from March 2024 till August 2024

Methodology: “After meeting selection criteria 246 patients of primary PCI were enrolled. Door-to-Balloon time was recorded. The primary outcome of this study was in-hospital mortality, with door-to-balloon time as the independent variable. Data were recorded in Proforma analyzed in SPSS version 23.

Results: The mean age was 49.20±15.82 years. Among the participants, 172 (69.9%) were male and 74 (30.1%) were female. The average door-to-balloon time was 81.13±23.50 minutes. Outcome comparison across door-to-balloon time categories revealed that in-hospital mortality occurred in 4 (6.6%) patients with door-to-balloon time <60 minutes, 13 (14.4%) cases with 60–90 minutes, and 20 (21.1%) patients with >90 minutes (p = 0.046). Similarly, MACE was observed in 11 (18%) cases with door-to-balloon time <60 minutes, 18 (20.0%) patients with 60–90 minutes, and 34 (35.8%) patients with >90 minutes (p = 0.014).

Conclusion: Door-to-balloon time significantly influences mortality in cases undergoing primary PCI, underscoring the need for the earliest possible intervention.
