在ADEPT研究中，对225例有症状的收缩性心力衰竭患者的组织多普勒成像和彩色M型舒张指数的预后价值进行了研究。65例患者发生死亡、移植或因心力衰竭住院的主要终点，其独立预测因素为减速时间缩短、肺静脉收缩期与舒张期流速比值降低以及早期二尖瓣流速与早期瓣环流速或传播速度比值升高。对于早期跨瓣速度与早期瓣环速度的比值，该预测对减速时间具有加性。较新的舒张指数提供了一个独立的预测临床结果。(c)2005年爱思唯尔公司All rights reserved.
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. (c) 2005 Elsevier Inc. All rights reserved.
