Abstract

Acute STEMI in diabetic patients leads to worse outcomes, making timely PCI crucial. However, the optimal timing (immediate vs. delayed) of percutaneous coronary intervention (PCI) for long-term recovery and complications in diabetic individuals is still being investigated. Objectives: To compare recovery and complication rates in diabetic acute STEMI patients undergoing immediate versus delayed PCI. Methods: This analytical cross-sectional study was conducted at a tertiary care hospital in Peshawar, Pakistan (October 2024 to March 2025), and enrolled 296 adult diabetic STEMI patients (aged ≥18 years) requiring PCI. After informed consent, data on demographics, medical history, procedural details, and post-PCI outcomes were collected via a structured questionnaire. Participants were categorized into immediate and delayed PCI groups, with statistical analysis using descriptive statistics and Chi-square tests to compare outcomes. Results: A total of 296 diabetic STEMI patients were enrolled, with 32.1% undergoing immediate PCI and 67.9% delayed PCI. The mean age was 55.89 ± 11.57 years, and 77% had type 2 diabetes. The delayed PCI group included a higher percentage of male; however, this variation was not significant. Baseline LVEF did not differ significantly (immediate: 40.54 ± 6.49 vs. delayed: 41.33 ± 7.23, p>0.05). Both groups showed significant post-PCI LVEF improvement (immediate: 49.12 ± 7.10, delayed: 50.85 ± 6.80), but the intergroup difference remained non-significant. No statistically significant differences were observed in intra- or post-procedural complications between the groups. Conclusions: In diabetic STEMI patients, a slight clinical delay in PCI did not significantly impact functional recovery (LVEF improvement) or increase intra- and post-procedural complications when compared to immediate intervention.
