Adenosine stress magnetic resonance imaging in women with low risk chest pain: the Emory University experience.
OBJECTIVE
The purpose of this study was to evaluate the accuracy of adenosine stress magnetic resonance imaging (ASMRI) for the evaluation of women with low-risk chest pain (CP).


BACKGROUND
Coronary artery disease (CAD) can present differently among women than among men. There is increased interest in the use of ASMRI for lower risk patients in the emergency department to rule out CAD, and it would be valuable to assess its performance specifically in women.


METHODS
This study included 82 women with low-risk CP who presented to the emergency department during a 2-year period at our institution and were evaluated by ASMRI. Clinical events were followed by review of medical records.


RESULTS
The specificity of ASMRI for ischemia detection in this small cohort of patients was 100%. Sensitivity was 94.9%, negative predictive value 100%, and positive predictive value 42.9%.


CONCLUSIONS
ASMRI may be used as the initial imaging modality for ruling out CAD in women with low-risk CP because of its very high sensitivity, specificity, and negative predictive value for the detection of ischemia. Further randomized controlled trials comparing ASMRI with established noninvasive nuclear and echocardiographic stress modalities are needed.
