Abstract
Objectives: (1) To describe clinical and paraclinical characteristics of STEMI patients undergoing PPCI; (2) To evaluate PPCI outcomes; (3) To determine D2B time and analyze factors associated with delayed D2B time (> 90 minutes). Materials and Methods: A retrospective case-series study on 109 consecutive STEMI patients undergoing PPCI from July 2024 to November 2025. Multivariable binary logistic regression was used to identify independent predictors of prolonged D2B time. Results: Mean age was 63 ± 13 years, 65.1% were male. Hypertension (76.1%) and smoking (56.0%) were the most prevalent risk factors. Overall, 56.0% self-presented, 54.1% were admitted off-hours, and 15.6% presented with Killip IV shock. LAD was the primary culprit vessel (47.7%), followed by RCA (38.5%). Multivessel disease occurred in 78.9%. Post-PCI TIMI 3 flow was achieved in 97.3%, procedural success was 96.3%, and in-hospital mortality was 5.5%. Median D2B time was 75 minutes (IQR: 64-90 minutes), with 76.1% achieving D2B ≤ 90 minutes. Multivariable regression identified off-hours admission (aOR = 5.72; 95% CI: 1.85-17.69; p = 0.002) and RCA culprit vessel (aOR = 2.86; 95% CI: 1.07-7.65; p = 0.037) as independent factors for prolonged D2B. Conclusion: Adherence to D2B ≤ 90 minutes reached 76.1% with a procedural success of 96.3%. Optimizing off-hours workflows and early resuscitation for RCA lesions are key strategies to minimize delays.
