Abstract: Introduction: cardiac resynchronization therapy (CRT) is a therapeutic modality for patients with heart failure (HF) refractory to optimized pharmacological treatment. Objective: this study aimed to analyze the main indications for the use of CRT in ICFEr available in the literature. Methods: This is a literature review in the following databases: New England Journal of Medicine, American Heart Association, SCIENSE, JACC. English articles were selected during the period 2002-2013. The Brazilian Guideline for Chronic and Acute Heart Failure was also consulted. Discussion: CRT has established itself as an important therapy in the treatment of HF, especially in patients with NYHA functional class III and IV. Its effectiveness has been widely documented in several clinical trials, which have shown clinical benefits related to improving symptoms, reducing hospital admissions and improving survival. Conclusion: from the analysis of the studies presented in this literature review, it is possible to conclude that CRT, when properly indicated, is capable of reducing mortality and morbidity, in addition to showing favorable impacts on improving quality of life and, consequently, functional class.
