Clinical Report: Gender-based Variations in Prognostic Importance of ECGs
Overview
This study investigates sex-specific differences in the prognostic value of preclinical ischemic ECGs for identifying myocardial infarction (MI) requiring target lesion revascularization (TLR) and mortality. It finds that ischemic ECGs predict TLR in women but not in men, highlighting significant gender disparities in acute coronary syndrome management.
Background
Cardiovascular diseases, particularly myocardial infarction, are leading causes of morbidity and mortality globally. Accurate identification of MI, especially in women who often present atypically, is crucial for timely intervention. Understanding the prognostic value of prehospital ECGs can improve diagnostic accuracy and treatment outcomes in both sexes.
Data Highlights
{'30-day mortality': {'women': '7%'}}
Key Findings
Men presented with ischemic ECGs more frequently than women (63% vs. 52%; p < 0.001).
Ischemic ECGs predicted TLR only in female patients (OR 1.86; 95% CI 1.38−2.54; p < 0.001).
30-day mortality was recorded at 7%, with 5-year mortality at 59% across the study population.
There was a significant association between ischemic ECG changes and mortality in both sexes.
Multivariable analysis confirmed the predictive value of ischemic ECGs for TLR in women (OR 1.79; 95% CI 1.22–2.60; p = 0.003).
Clinical Implications

Conclusion
The study underscores the importance of considering sex-specific differences in the prognostic value of prehospital ECGs, which can guide better management of myocardial infarction and improve patient outcomes.
