Gender differences in the clinical features and outcomes of patients with coronary artery disease

ABSTRACT Introduction: Women have been at a higher risk for adverse cardiac events following percutaneous coronary intervention (PCI), compared with men. Areas covered: In this review, authors discuss the gender differences that can affect the clinical outcomes after PCI and the important points that can be improved on. Expert commentary: Various factors, such as old age and higher prevalence of comorbidities, have been considered to account for the worse clinical outcomes of PCI in women than in men. In addition, men and women have different presentations of angina or acute coronary syndrome (ACS); atypical symptoms are more frequent in women. This variation of the clinical presentation in women likely contributes to the misdiagnosis or delayed recognition of ischemia, which may explain the worse clinical outcomes. In addition, compared with men, women are less likely to be referred for revascularization for coronary artery disease (CAD) and receive less of these guideline-recommended therapies. Recently, sex differences in cardiovascular events have decreased, especially among stable CAD patients, but sex differences in the clinical outcomes of ACS remain. Further evolution of treatment is expected to narrow these sex differences among patients with CAD and improve the clinical outcomes of both men and women.
