Abstract

Objectives: This study to evaluate the outcomes of treating bradyarrhythmias in patients with acute myocardial infarction who underwent percutaneous coronary intervention during their inpatient stay and to identify some related factors. Methods: A descriptive cross-sectional study was conducted on 51 acute myocardial infarction (AMI) patients who presented with bradycardia and underwent percutaneous coronary intervention (PCI). Results: The mean age of the cohort (76.5% male) was 67.2 ± 12.9 years. Sinus bradycardia accounted for 54.9%, while complete atrioventricular block was observed in 25.5%. Atropine was administered to 29.41% of patients for bradycardia management. Temporary pacing was required in 29.41% of cases, with a mean duration of 30.93 ± 22.0 hours. The culprit vessel was predominantly the Right Coronary Artery (RCA) (78.4%), and multi-vessel disease was present in 58.8%. Post-PCI, 96.08% achieved TIMI 3 flow. Notably, no patients required permanent pacing, and the in-hospital mortality was one case. The mean hospital stay was 4.18 ± 2.53 days. Conclusion: Timely medical management combined with appropriate coronary intervention effectively restores stable heart rhythm in AMI patients with bradycardia, thereby reducing the need for permanent pacing.
