The Significance of ST Depression in a Postmenopausal Woman on Estrogen Therapy during Regadenoson Myocardial SPECT Imaging

الملخص EN

The incidence of false-positive stress tests has been noted in women, especially on hormone replacement therapy.

Current literature describes this phenomenon in treadmill and adenosine stress tests.

The introduction of regadenoson as a vasodilator agent has been widely adopted owing to its potency and specificity.

To our knowledge, false-positive stress test with regadenoson in a postmenopausal woman on estrogen has never been described.

Given the higher chronotropic response with regadenoson, we believe that normal perfusion images with a higher heart rate response indicate a good prognosis in such patients.
