Background: Inferior Wall Myocardial Infarction with and without Right Ventricular Infarction, presents significant electrical and mechanical complications. Gender-based differences in these complications remain unclear. This study aimed to evaluate gender- specific variations in IWMI complications among patients aged 40–80 years at LRH and PIC.
Methodology: This study was cross section, and involved all the patients, who had Inferior Wall Myocardial Infarction from July 2024 to December 2024 at Lady Reading Hospital and Peshawar Institute of Cardiology. This study employed 246 participants based on sample size. Data were collected through a questionnaire focusing on demographic, clinical, and angiographic variables. Complications were categorized as mechanical or electrical. Statistical analysis, including Chi-square tests, assessed gender differences in complications and treatment outcomes.
Results: Mechanical complications were the most common, with Regional Wall Motion Abnormality affecting 77.6% of participants, Mitral Regurgitation in 17.1%, and VSR in 0.8%. Electrical complications were less frequent, with Heart Block, including complete Heart Block, observed in 4.9% of patients. Right Ventricular Infarction occurred in 8.1% of Inferior Wall Myocardial Infarction cases. There were not statistically association gender differences at the prevalence of complications or outcomes. Most patients underwent Percutaneous Coronary Intervention, while fewer received CABG or thrombolytic therapy. Dual antiplatelet therapy was the predominant medical intervention.
Conclusion: The study found no significant gender differences in the electrical and mechanical complications of Inferior Wall Myocardial Infarction. The timely Percutaneous Coronary Intervention and management of comorbidities are critical in improving outcomes. The findings support gender-neutral treatment protocols for Inferior Wall Myocardial Infarction but emphasize the need for individualized care and further research to validate these results and assess long-term outcomes across diverse populations.
