摘要

目的：应用实时三平面应变率成像检测舒张性心力衰竭患者左心室局部心肌收缩功能，探讨其临床意义。方法：选取舒张性心力衰竭患者29例、收缩性心力衰竭患者26例和正常人30例，应用实时三平面应变率成像测定左心室各壁基底段和中间段收缩期峰值应变率（SRs）。结果：舒张性心力衰竭组、收缩性心力衰竭组左心室壁各节段SRs均小于正常组相应节段（P＜0.05或P＜0.01），且正常组、舒张性心力衰竭组、收缩性心力衰竭组各组SRs逐渐减小（P＜0.05或P＜0.01）。结论：舒张性心力衰竭患者存在左心室局部心肌收缩功能异常，实时三平面应变率成像检测左心室局部心肌收缩功能在心力衰竭患者心脏功能评价中具有重要价值。

Abstract

Objective:　To evaluate the left ventricular regional myocardial systolic function in patients with diastolic heart failure using real-time triplane strain rate imaging and investigate its clinical significance. Methods: Twenty-nine patients with diastolic heart failure, 26 patients with systolic heart failure and 30 healthy subjects as control group were enrolled. The systolic peak strain rate(SRs) were measured at basal and middle segments in different left ventricular walls using real-time triplane strain rate imaging. Results: SRs in diastolic heart failure and systolic heart failure groups were significantly lower than in control group(P＜0.05 or P＜0.01). There was a significantly step-down change among normal, diastolic heart failure and systolic heart failure in SRs(P＜0.05 or P＜0.01). Conclusions: The left ventricular regional myocardial systolic dysfunction existed in patients with diastolic heart failure. Thus, assessing left ventricular regional myocardial systolic function using real-time triplane strain rate imaging has important clinical value in the comprehensive evaluation of cardiac function in heart failure.
