Abstract :
The prognostic values of tissue Doppler imaging and color M-mode diastolic indexes were studied in 225 patients who had symptomatic systolic heart failure in the ADEPT study. The primary end point of death, transplantation, or hospitalization due to heart failure occurred in 65 patients and was independently predicted by shorter deceleration time, lower ratio of pulmonary vein systolic to diastolic velocity, and increasing levels of the ratios of early transmitral velocity to early annular velocity or velocity of propagation. For the ratio of early transmitral velocity to early annular velocity, this prediction was additive to deceleration time. Newer diastolic indexes provide an independent prediction of clinical outcomes.
