Noninvasive Technologies for Diagnosing Coronary Artery Disease in Women

Slide: 19 of 23

Conclusions (2 of 2)

Analyses determined that for women with no previously known CAD, there were statistically significant differences between the accuracy of the available modalities (p < 0.001). The sensitivities of ECHO and SPECT were significantly higher than that of ECG. The specificity of ECG was less than those of CMR (borderline) and ECHO. In the subset of studies that were of good quality and where there was no known CAD in the included population, analyses demonstrated statistically significant differences between the performance of the diagnostic tests (p = 0.006), with the specificity of ECG being less than those of CMR and ECHO.

Evidence was insufficient to permit meaningful conclusions about the predictors of the diagnostic accuracy of NITs and about the usefulness of NITs in improving clinical outcomes and supporting clinical decisionmaking.
