Official title
Beta-blocker Uptitration in Heart Failure Patients Receiving Cardiac Resynchronization Therapy With Optivol Fluid Status Monitoring System
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Many heart failure patients are unable to reach target beta blocker doses. This study will address whether cardiac resynchronization therapy (CRT) will enable uptitration of beta-blockers to target doses and whether it will favorably affect remodeling by reducing left ventricular end systolic volume (LVESV), with measurable clinical benefit, beyond CRT alone (without changes in beta-blocker dose).
