Objective: To determine the frequency of left ventricular function decline in patients undergoing primary PCI for STEMI.
Study Design: Prospective longitudinal study.
Place and Duration of Study: Department of Cardiology, Punjab Institute of Cardiology, Lahore Pakistan, from Dec 2024 to Jun 2025.
Methodology: This study was done after taking ethical approval from IRB of Punjab Institute of Cardiology, Lahore. This study was done on 66 patients diagnosed with acute STEMI undergoing primary PCI after taking informed consent. Data collection was done using pre-designed proforma. >5% decrease in ejection fraction as compared to pre PCI at follow up (48 hours post PCI and 4 weeks) was defined as decline in LV function. Data analysis was performed using SPSS version 26, with p-value <0.05 considered significant.
Results: LV function decline was observed in 28.8% participants, with significantly higher frequency was observed in those who presented late and had multiple vessel disease p= 0.047 and 0.001, respectively. The LVEF before PCI (53.27±3.67%), after PCI (52.10±3.91%), and at four weeks follow-up (51.66±4.32%), indicating gradual decline in LVEF over time.
Conclusion: This study highlights that significant proportion of patient’s experience decline in left ventricular function following primary PCI for STEMI. The findings underscore the critical impact of delayed presentation and presence of multivessel coronary artery disease on post-procedural LV performance. These results emphasize the importance of early intervention and comprehensive assessment of coronary anatomy to optimize long-term cardiac function and outcomes in STEMI patients undergoing PCI.
