Do noninvasive imaging tests improve diagnostic accuracy for coronary artery disease compared to conventional exercise testing in women with chest pain?
Do noninvasive imaging tests improve diagnostic accuracy for coronary artery disease compared to conventional exercise testing in women with chest pain?
In women with suspected coronary artery disease, imaging modalities like stress echocardiography and myocardial perfusion scintigraphy provide better diagnostic accuracy than conventional exercise ECG, which has a higher rate of false positives.

May support imaging over ECG for CAD detection in women; leaves open prospective outcome validation.
. Noexplanations for this fact are available, although specula-tions exist about the inadequate manner of diagnosis.It is worth emphasizing that in studies about coronarydisease, women are either a minority or excluded from thestudy protocols. Therefore, most of the information regar-ding coronary disease in women comes from studies con-ducted in men. In fact, invasive cardiovascular procedures- either diagnostic or therapeutic - are frequently less indi-cated for women who bear confirmed coronary disease.However, it is not yet clearly established whether this diffe-rence is due to a larger use of such procedures in men or to asmaller indication in women.Typical angina is more prevalent in women, althoughangiographic studies have revealed that all forms of angina,including the typical type, are associated on a smaller scalewith coronary disease in women when compared with thatmen.
