Large outcomes study. Two questions to ponder:
1. How would a longer follow-up period (more than the 13 months used in this study) affect the results? Would it increase even further the predictive ability of exercise E/e’?
2. The study showed poor accuracy of E/e’ to detect “angiographically significant” stenosis. The authors mention the lack of use of contrast as a possible cause. What else could’ve improved the accuracy? Using 70% stenosis as a cut-off instead of 50%?

Although there has been some recent controversy over the diagnostic utility of the E/e’ ratio, here is a stress Echo study showing the prognostic utility of E/e’. The standout finding of this study was the predictive ability of exercise E/e’ incremental to exercise capacity and wall motion score index.
