NCT00251251

Brief Summary

Congestive heart failure (CHF) is a common health problem that leads to frequent hospitalizations and an increased death rate. In spite of advances in drug therapy, it remains a significant public health problem. Recently, a new therapy has been developed for advanced heart failure patients with a ventricular conduction abnormality. This new therapy, called cardiac resynchronization (CRT), is a device which stimulates the atrium, the right ventricle, and the left ventricle providing synchronization of the contraction of the heart chambers. It is the addition of this therapy to an implantable cardioverter defibrillator (ICD) that will be evaluated in this study. This study will compare whether the implantation of this new therapy device, in combination with an implantable cardioverter defibrillator, will reduce total mortality and hospitalizations for CHF.

  • Intrinsic QRS complex width ≥ 120 ms OR paced QRS measurement ≥ 200 ms
  • ICD indication for primary or secondary prevention

You may not qualify if:

  • Intravenous inotropic agent in the last 4 days
  • Patients with a life expectancy of less than one year from non-cardiac cause

  • Coronary revascularization (coronary artery bypass graft surgery \[CABG\] or percutaneous coronary intervention \[PCI\]) \< 1 month if previously determined LVEF \> 30%. Patients with a more recent revascularization can be included if a previously determined LVEF was ≤ 30%.
  • Patients with an acute coronary syndrome including myocardial infarction (MI) can be included if the patients have had a previous MI with LV dysfunction (LVEF ≤ 30%).
  • Patients included in another clinical trial that will affect the objectives of this study
  • History of noncompliance to medical therapy
  • Unable or unwilling to provide informed consent
