Population

169 patients aged 40 to 80 years presenting with STEMI within 12 hours of chest pain onset and undergoing primary PCI. Mean age 55.96 years, 76.9% male. Excluded: prior cardiac surgery, known AF, AF after cardioversion, LVEF <20%.

Outcome

Incidence of new-onset atrial fibrillationhard clinical

Limitations

Cross-sectional study design limits strength of evidence
Lack of prior sample size calculation
Limited number of outcomes and variables assessed
Cross-sectional study design limits strength of evidence and causal inference
Sample size calculation not required for this design, considered a drawback
Limited outcomes selected, missing other factors and variables to determine cause and effectiveness

Implication

New-onset atrial fibrillation occurs in approximately 15% of STEMI patients undergoing primary PCI and is significantly associated with older age.

Abstract

Aim: This study aims to find out the incidence of atrial fibrillation new onset in STEMI patients receiving primary PCI Sample: A total of 169 patients have included after sample size calculation by using WHO sample size calculator version 2.0. Study Design: Descriptive cross-sectional study Place and Duration of study: This study was conducted at the Department of Interventional Cardiology of CHU Ibn Rochd to Casablanca (Morooco) March, 2022, To December 2022. Methodology: The inclusion criteria set for data collection were as; all the patients undergoing Primary PCI with age between 40 to 80 years, males and females, patients presented with 12 hours of the onset of chest pain with STEMI to enroll in the study. Whereas, patients who had a previous history of any cardiac-related surgery and known AF, also all the patients suffered AF after trial of cardioversion, and those patients who had ejection fraction less than 20% were excluded from the study. Result: The demographic classification showed the mean age of the patients was 55.96±8.9 with a CI of 54.60 to 57.33 years. The mean height of the patients was 167.34±0.56 with CI of 166.2 to 168.46. The mean weight of the patients was 74.84±0.7 with CI of 73.39 to 76.29 kg. The average BMI of all the patients was 26.7±0.28 with CI of 26.2 to 27.33. The analysis of the data revealed that Atrial fibrillation is more common people who don’t smoke tobacco and are non-diabetic. Diabetic patients are less prone to atrial fibrillation in MI. Conclusion: The prevalence of new-onset of atrial fibrillation was found to be high in elderly age group patients.
