Proportion of patients in a congestive heart failure care management program meeting criteria for cardiac resynchronization therapy

Among 1,138 patients in our congestive heart failure care management database, 37 (3.2%) met guideline criteria for cardiac resynchronization therapy. Advancing age was a predictor of prolonged QRS duration in this population, but gender, ejection fraction (EF) and cause of heart failure were not. There was a trend toward an inverse correlation between QRS duration and EF among patients with EF ≤35%.
