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

Abstract

Objective: To examine the relationship between coronary artery dominance and complications after primary
percutaneous 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) and
the 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 observational
study. 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 patients
had primary percutaneous coronary intervention (PCI) at the study centers. Patients who had CABG, significant
coronary anomalies, or inadequate medical data were excluded from the research. Electronic medical records
and 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 was
mostly 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, whereas
right dominance was noted in 35.3%. Co-dominance was detected in 17.6% of cases. Myocardial reperfusion
injury, 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 artery
dominance. However, patient demographics, comorbidities, lesion characteristics, and procedures may alter
PCI outcomes.
