Association of Coronary Artery Dominance with Post-Primary Percutaneous Coronary Intervention Complication in ST-Segment Elevation Myocardial Infarction: Retrospective Observational Study, Rawalpindi

Objective: To examine the relationship between coronary artery dominance and complications after primarypercutaneous coronary intervention in patients with ST-elevation myocardial infarction (STEMI).Study Design: Retrospective observational study.Place and Duration of Study: This study was conducted at the Armed Forces Institute of Cardiology (AFIC) andthe National Institute of Heart Diseases (NIHD), Rawalpindi, Pakistan from February 2023 to January 2024.Methods: Coronary artery dominance and complications following initial percutaneous coronary intervention(PCI) in ST-segment elevation myocardial infarction patients were examined in this retrospective observationalstudy. The Armed Forces Institute of Cardiology and National Institute of Heart Diseases in Rawalpindi,Pakistan, conducted this investigation. From February 2023 to January 2024, 85 consecutive STEMI patientshad primary percutaneous coronary intervention (PCI) at the study centers. Patients who had CABG, significantcoronary anomalies, or inadequate medical data were excluded from the research. Electronic medical recordsand angiographic databases included demographics, medical history, angiographic results, procedure details,and post-PCI issues.Results: The study comprised 85 patients diagnosed with STEMI at an average age of 59.4 years. The group wasmostly made up of male patients, accounting for 76.5% of the total. Comorbidities such as hypertension(52.9%) and diabetes mellitus (35.3%) were prevalent. Left dominance was seen in 47.1% of instances, whereasright dominance was noted in 35.3%. Co-dominance was detected in 17.6% of cases. Myocardial reperfusioninjury, no-reflow phenomenon, and distal embolization occurred in 17.6%, 23.5%, and 11.8% of patients,respectively.Conclusion: According to our results, STEMI post-PCI morbidity may not be affected by coronary arterydominance. However, patient demographics, comorbidities, lesion characteristics, and procedures may alterPCI outcomes. How to cite this: Gul SJ, Nadeem A, Samore NA, Gul SF, Bilal A, Hasan F.
