[摘要] 心脏再同步化治疗(cardiac resynchronization therapy,CRT)是有效治疗心力衰竭的非药物措施。CRT主要适应证为NYHA分级Ⅱ~Ⅳ级、窦性心律和完全性左束支传导阻滞患者,也适用于部分非左束支传导患者。尽管CRT在多数患者中可明显改善患者预后,但在部分患者中效果不佳,表现为CRT无反应者。如何减少CRT无反应者比例是CRT临床应用中的重要问题。该文对CRT治疗心力衰竭机制、目前主要临床研究结果和CRT无反应的可能原因及解决方案作一综述。 |

Abstract: |
[Abstract] Cardiac resynchronization therapy(CRT) is an effective non-drug strategy for patients with chronice heart failure(CHF). It is highly recommended to treat CHF patients with NYHA class Ⅱ~Ⅳ, sinus rhythm and left bundle branch block. It can also be used in some non-left bundle branch block CHF patients. Althought CRT is effective in most patients, there are still some CHF patients who are not significantly improved by it(CRT nonresponders). How to reduce the proportion of CRT nonresponders is an inportant issue in the clinical application of CRT. In this review focus on the mechanisms of CRT, the results of CRT clinical trials, and the causes and solutions for CRT nonresponders. |
