Abstract

Heart failure is a major health problem in the United States, associated with high morbidity, mortality, and economic burden. Despite recent advances in pharmacological treatments to attenuate disease progression, medications become relatively ineffective, resulting in worsening congestive symptoms and increased exercise intolerance. Cardiac resynchronization therapy provides a new adjunct for heart failure patients who remain symptomatic despite optimized medical therapies. This article discusses cardiac resynchronization therapy and measures that should be considered to ensure proper functioning of the device and improved quality of life for patients.
