Sex-Related Outcomes of Medical, Percutaneous, and Surgical Interventions for Coronary Artery Disease
Key result
Women with coronary artery disease experience delays in diagnosis, receive less aggressive treatments, and have worse outcomes following medical, percutaneous, and surgical interventions compared to men.
Why the study?
Despite known sex-related variations in CAD epidemiology, diagnosis, and treatment outcomes, women remain underrepresented in clinical studies and sex-specific management guidelines are generally lacking.
Does sex affect the outcomes of medical, percutaneous, and surgical interventions in patients with coronary artery disease?
Key Points
- The aim is to analyze differences in treatment outcomes for coronary artery disease between men and women.
- Reviewed existing literature on sex-specific outcomes for medical, percutaneous, and surgical interventions in CAD.
- Analyzed delays in diagnosis and treatment aggressiveness across genders.
- Examined representation of women in clinical studies.
- Women often present with atypical symptoms leading to diagnosis delays.
- Less aggressive treatment approaches in women contribute to worse outcomes following interventions.
- Current clinical guidelines lack sex-specific management strategies, despite known differences.

“If you are a man, and you need coronary revascularisation, you will receive what we call evidence-based treatment, because there is strong evidence to guide your treatment decision. If you are a woman, that's not the case. We don't have data, and so we use the data generated in men. However, we all know that women are not small men.”
“This consensus is an international collaborative effort that highlights the knowns, the gaps and ambiguities in evidence related to sex-specific revascularization. As a companion to the recent percutaneous coronary intervention (PCI) guidelines, it will inform clinicians on best practices most relevant to our female patients and draws attention to areas in need of additional evidence.”
“Although our study suggests that bypass surgery may offer more long-term protection compared to stents, anatomical considerations, individual surgical risk, and patient preferences remain critical.”
Implication
This review highlights significant sex-based disparities in the presentation, management, and outcomes of coronary artery disease, emphasizing the need for better representation of women in clinical studies and sex-specific guideline recommendations.
Abstract
Biological and socio-cultural differences between men and women are complex and likely account for most of the variations in the epidemiology and treatment outcomes of coronary artery disease (CAD) between the two sexes. Women are more likely to present with atypical symptoms and less likely to be referred for invasive testing. They often experience delays in diagnosis and receive less aggressive treatments compared to men. Worse outcomes in women have been described following both conservative and invasive treatments of CAD. Despite the growing recognition of sex-specific determinants of outcomes, representation of women in clinical studies remains low, and sex-specific management strategies are generally not provided in guidelines. In this review, we summarize the current evidence on sex-related differences in patients with CAD, focusing on the differential outcomes following medical therapy, percutaneous coronary interventions, and coronary artery bypass surgery.
