“…Our findings contribute to the understanding of how the timing of hospital presentation influences the management and outcomes of acute STEMI, corroborating with existing studies that have reported longer D2B times for patients presenting during off-hours compared to those during regular operational hours (10,11). The observed delays in reperfusion therapy initiation during off-hours have been attributed to a range of factors, including the limited availability of staff, specialized personnel, and logistical challenges associated with mobilizing the cardiac catheterization team (12,13). While our analysis revealed no statistically significant difference in mortality rates or the incidence of complications such as cardiogenic shock and heart failure between off-hours and regular hours presentations, there was a discernible trend towards higher rates of adverse events among the off-hours group.…”

Background: The timely management of ST-segment elevation myocardial infarction (STEMI) through primary percutaneous coronary intervention (PCI) significantly impacts patient outcomes. However, the influence of off-hours presentation (nights, weekends, and holidays) on door-to-balloon (D2B) time and clinical outcomes remains a pivotal concern, as it potentially affects the efficiency of care and patient prognosis. Objective: This study aims to evaluate the association between off-hours presentation, D2B time, and clinical outcomes in patients undergoing primary PCI for STEMI, to identify potential disparities in treatment efficacy and to inform strategies for improving cardiovascular emergency care. Methods: Conducting a retrospective cross-sectional analysis, this study included 90 patients admitted with STEMI who underwent primary PCI at a tertiary care center between March 2022 and March 2023. Patients were stratified into two groups based on the timing of hospital presentation: off-hours and regular hours. Primary outcomes assessed were D2B time, mortality rates, and incidences of cardiogenic shock and heart failure. Data were analyzed using descriptive statistics, t-tests, chi-square tests, and multivariable logistic regression to adjust for potential confounders. Results: The mean D2B time for patients presenting during off-hours was significantly longer (96.4 ± 12.3 minutes) compared to those presenting during regular hours (84.6 ± 9.8 minutes, p<0.001). No statistically significant differences were observed in mortality rates (off-hours 4.4% vs. regular hours 6.7%, p=0.155), cardiogenic shock (off-hours 6.7% vs. regular hours 4.4%, p=0.351), or heart failure (off-hours 8.9% vs. regular hours 6.7%, p=0.214). Multivariable analysis confirmed off-hours presentation as an independent predictor of prolonged D2B time (coefficient 11.8, 95% CI 8.2-15.5). Conclusion: Off-hours presentation is associated with significantly longer D2B times in STEMI patients undergoing primary PCI, underscoring the need for healthcare systems to address the disparities in care delivery during off-hours. However, no significant differences in short-term clinical outcomes were observed, suggesting that factors beyond D2B time contribute to patient prognosis. Further studies are warranted to explore comprehensive strategies to optimize care irrespective of presentation time.
