Figure 2 Incremental value of early diastolic mitral annular velocity (Em) <3 and early diastolic transmitral flow velocity (E)/Em >15 in predicting long-term (median 48 months) cardiac mortality. The addition of deceleration time (DT), E/Em, and Em resulted in significant incremental improvements in the predictive value of a model including clinical risk factors (age, ischemic heart disease, valvular heart disease, and heart failure): chi-square ( 2) = 25.0 with five degrees of freedom for clinical risk factors; chi-square = 29.4 with one degree of freedom for clinical risk factors plus DT  140 ms; chi-square = 33.0 with one degree of freedom for clinical risk factors plus DT 140 ms plus E/Em >15; and chi-square = 37.3 with one degree of freedom for clinical risk factors plus DT <140 ms plus E/Em >15 plus Em <3.
