Experimental: aCRT ON
The aCRT algorithm has been developed to provide RV-synchronized LV pacing when intrinsic AV conduction is normal or BiV pacing otherwise
Device: aCRT ON
CRT device with AdaptivCRT enabled
Active Comparator: aCRT OFF
Device: aCRT OFF
CRT device with AdaptivCRT disabled
- Combined endpoint of all-cause mortality and intervention for heart failure decompensation [ Time Frame: 2 years post randomization ]Intervention for heart failure decompensation is defined as an event requiring invasive intervention or inpatient hospitalization.
- All-cause mortality [ Time Frame: 2 years post randomization ]
- Percent of patients with interventions for heart failure decompensation [ Time Frame: 2 years post randomization ]Intervention for heart failure decompensation is defined as an event requiring invasive intervention or inpatient hospitalization.
- Clinical Composite Score [ Time Frame: 6 months post randomization ]The Clinical Composite Score classifies patients according their clinical status at 6 months post randomization into categories Improved, Unchanged, and Worsened. A patient is classified Worsened in case of death, hospitalization for worsening heart failure, worsened NYHA class (using last observation carried forward), or worsened status on the Global Assessment Score. Also patients that exit the study or cross over because of worsening heart failure are classified Worsened. A patient is classified Improved when not Worsened and there is an improvement in NYHA class or Global Assessment Score. Patients that are not Worsened or Improved are Unchanged.
- Atrial fibrillation [ Time Frame: 2 years post randomization ]Incidence of atrial fibrillation lasting >6 hours in one day
- Change in Quality of Life measured by the Kansas City Cardiomyopathy Questionnaire (KCCQ) [ Time Frame: Baseline to 2 years post randomization ]The overall summary score of the Kansas City Cardiomyopathy Questionnaire will be analyzed.
- Change in Quality of Life measured by the EQ-5D [ Time Frame: Baseline to 2 years post randomization ]The EQ-5D index score will be analyzed.
- All-cause re-admissions within 30-days after a heart failure admission [ Time Frame: 2 years post randomization ]
