Use of cardiac resynchronization therapy in patients hospitalized with heart failure.
BACKGROUND: The frequency and characterization of patients receiving cardiac resynchronization therapy (CRT) are largely unknown since the publication of pivotal clinical trials and subsequent incorporation of CRT into the American College of Cardiology/American Heart Association guidelines for heart failure. METHODS AND RESULTS: We analyzed 33,898 patients admitted from January 2005 through September 2007 to 228 hospitals participating in the American Heart Association's Get With the Guidelines-Heart Failure program. There were 4201 patients (12.4%) discharged alive with CRT, including 811 new implants. Patients discharged with CRT were older (median age, 75 versus 72 years) and had lower median left ventricular ejection fraction (30% versus 38%), more frequent ischemic cardiomyopathy (58% versus 45%), more history of atrial fibrillation (38% versus 27%), and higher rates of beta-blocker and aldosterone antagonist use (P<0.0001 for all) than those without CRT. We found that 4.8% of patients with left ventricular ejection fraction
