摘要 心脏再同步治疗（CRT）是晚期心力衰竭的重要治疗方法,从超声心动图（UCG）得到的左室机械不同步参数可作为CRT应答的重要预测因子,但在现有临床条件下,UCG技术包括组织多普勒成像（TDI）和心肌应变率成像,其作为常规临床手段来评价左室不同步还存在严重缺陷.目前的研究显示,门控心肌灌注SPECT相位分析技术能够用于CRT应答的预测,与基于UCG的TDI相比,其优势在于技术操作的高度自动化和结果的高度可重复性. Cardiac resynchronization therapy （CRT） has shown benefits in patients with advanced heart failure. It has shown with ultrasound cardiogram （UCG） that the presence of left ventricular mechanical dyssynchrony is an important predictor for response to CRT. Therapy trial showed that under present conditions the current available UCG techniques including tissue Doppler imaging （TDI） and myocardial strain-rate imaging are not ready for routine clinical practice to assess left ventricular dyssynchrony. Research now shows that the advantages of gated myocardial perfusion SPECT over TDI are its automation,repeatability, and reproducibility that are very promising in improving prediction of CRT response in heart failure patients.
