The increased awareness of the incidence and risk of coronary heart disease (CHD) has increased the efforts of physicians to identify women with CHD as early as possible. Exercise electrocardiogram (ECG) testing and imaging have been used in this manner for men and women but represent unique challenges with regard to women. Exercise ECG testing, which determines the presence of coronary artery disease by the provocation of ST depression and chest pain, has a lower positive predictive value in women than in men of the same age. This is explained by a lower prevalence of CHD in female patients with symptoms and (to a lesser extent) by the reported lower sensitivity and specificity of the test in women as compared with men. Exercise nuclear isotope myocardial perfusion imaging and exercise echocardiography have higher reported specificity and sensitivity, and new imaging agents, contrast echo agents, and acquisition protocols have reduced the limitations of these studies in selected women. The value of the exercise ECG examination with regard to CHD event risk assessment is equal in men and women and should be incorporated into the clinical evaluation of appropriate women patients.
