Figure 5 Incremental Value of E/Ea >15 in Predicting All-Cause Mortality

The addition of left ventricular ejection fraction (LVEF), deceleration time (DT), and the ratio of transmitral E and mitral annular velocity (E/Ea) resulted in significant incremental improvements in the predictive value of a model including clinical variables (age, Killip class 2 on admission, anterior myocardial infarction, and myocardial revascularization during the index admission): chi-square = 20.8 for clinical factors; chi-square = 28.8 for clinical factors plus LVEF; chi-square = 33.2 for clinical factors plus LVEF plus DT 140 ms; and chi-square = 43.0 for clinical factors plus LVEF plus DT 140 ms plus E/Ea >15.
