Insights
Coronary heart disease (CHD) presents unique challenges in women, affecting diagnosis and treatment outcomes for procedures like percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) surgery.
Area of Science:
- Cardiology
- Vascular Medicine
- Women's Health
Background:
- Coronary heart disease (CHD) exhibits significant sex-based differences compared to men.
- Women experience smaller coronary arteries, complicating percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) surgery.
- Atypical acute coronary syndrome (ACS) symptoms in women, delayed medical help-seeking, and underestimation of symptoms contribute to diagnostic challenges and care delays.
Purpose of the Study:
- To highlight the distinct challenges and outcomes of CHD in women compared to men.
- To examine the implications of anatomical differences and diagnostic delays on revascularization procedures in women.
- To assess the effectiveness of cardiovascular risk prevention strategies, including statins, in women.
Main Methods:
- Comparative analysis of CHD presentation and outcomes in women versus men.
- Review of challenges and outcomes associated with PCI and CABG surgery in female patients.
- Evaluation of diagnostic delays and symptom underestimation in women with ACS.
- Assessment of the role of inflammation and comorbidities in female CHD patients.
Main Results:
- Women face greater challenges during PCI and CABG due to smaller coronary arteries.
- Delayed diagnosis and treatment for ACS in women are linked to atypical symptoms and healthcare provider biases.
- Despite advancements, women experience higher rates of adverse outcomes post-PCI and CABG, though this gap is narrowing.
- Younger women with CHD have higher mortality rates than comparable men.
- Statins demonstrate beneficial outcomes in women for cardiovascular risk prevention.
Conclusions:
- CHD management in women requires tailored approaches addressing anatomical, diagnostic, and treatment disparities.
- Advancements in invasive techniques have improved outcomes, but further optimization is needed for women.
- Achieving similar long-term mortality benefits from CABG as PCI in women with complex CHD may necessitate a lower anatomical SYNTAX score.
Abstract:
There are significant differences in coronary heart disease (CHD) in women whenever a comparison is made to men and these carry over to revascularization procedures including percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) surgery. The coronary arteries of women are smaller, which presents additional challenges for PCI and CABG procedures. Unique atypical symptomatology in response to acute coronary syndrome (ACS) in women can confound diagnosis, women notoriously delay seeking medical help for ACS, and physicians and other caregivers have had a tendency to minimize the significance of these symptoms, contributing further to a delay in necessary care. There also appears to be an increased association of inflammation and CHD in women. The younger the female patient with CHD, the higher the mortality and that mortality clearly exceeds that of comparable male patients. For cardiovascular (CV) risk prevention in women, statins have had controversy associated with their use but overall, the proof of beneficial outcomes results from statins is also valid in women. An increased rate of adverse outcomes has been reported in women after PCI and CABG surgery. These worse clinical outcomes have persisted in contemporary years but lessened due to advancement in invasive techniques. Nevertheless, PCI that could improve clinical outcomes in women who have high-risk ACS is, unfortunately, performed on a less frequent basis and, in addition, there are greater delays involving women as compared to men. With increased clinical comorbidity associated with complex CHD in women, a lower anatomical SYNTAX score (from: SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery [SYNTAX] trial) appears necessary in order for women to achieve a similar long-term mortality benefit from CABG surgery as compared to PCI.
