Left ventricular 12 segmental strain imaging predicts response to cardiac resynchronization therapy

摘要：

Background Non-response to cardiac resynchronization therapy (CRT) exposed the need for better patient selection criteria for CRT.This study aimed to identify favorable echocardiographic parameters in improving response to CRT.Methods 45 consecutive patients receiving CRT-D implantation for heart failure (HF) were included in this prospective study.NYHA class, 6-minute walk distance, electrograph character and multi echocardiographic parameters especially in strain patterns were measured and compared before and 6 month after CRT in responder and non-responder groups.Response to CRT was defined as a decrease in LVESV of 15％ or more at 6 month follow up.
