Improving the Positive Predictive Value of Exercise Testing in Women for Coronary Artery Disease

Improving the Positive Predictive Value of Exercise Testing in Women for Coronary Artery Disease The exercise treadmill test (ETT) in women has been limited by a low positive predictive value (PPV) for coronary artery disease (CAD). However, the reliability of previous studies was unsatisfactory because of the inclusion of younger women with a low prevalence of CAD. To further evaluate the diagnostic properties of the ETT in women, we evaluated a group of women with chest pain who had a positive ETT result and subsequent coronary angiography. Of the 111 women, 56 had significant CAD on angiogram, yielding a PPV of 51% for the group. However, inclusion in the analysis of several pretest attributes and specific exercise test responses improved the PPV of the ETT. Age had a major effect, with the youngest group (35 to 50 years old) having a PPV of 36% compared to 68% in the oldest group (>65 years old). Several specific exercise responses (ST-segment depression >2 mm and delayed ST-segment recovery >3.0 minutes) further separated true from false positives across all age groups, increasing the PPV to approximately 80%. Onset of ischemia at a relatively low cardiac workload of <80% maximum predicted heart rate was not a significant predictor. In conclusion, the standard ETT should remain the test of choice in ambulatory women with chest pain and no significant abnormalities on baseline electrocardiogram especially in those >65 years of age. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png The American Journal of Cardiology Elsevier
