Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

• NYHA class III–IV congestive heart failure, in spite of optimal medical treatment for their congestive heart failure for 1 month.

The medical treatment must include a 40 mg/day minimum dose of furosemide (or equivalent);

  • Permanent atrial fibrillation (AF);
  • Left ventricular ejection fraction (LVEF) ≤ 35%;
  • Indication for a pacemaker implantation for a permanent and symptomatic bradycardia, or already implanted pacemaker under the condition that leads positioning corresponds to the criteria described in the protocol;
  • Aortic pre-ejection delay at least equal to 140 ms.

Exclusion Criteria:

  • Indication for a cardiac defibrillator;
  • Having presented a myocardial infarct within the previous 3 months;
  • Having undergone cardiac surgery or coronary revascularization procedure within the previous 3 months, or being scheduled for such procedures;
  • Presenting chronic pulmonary insufficiency;
  • Patients whose congestive heart failure requires the use of an intravenous inotropic support;
  • Presenting a dysthyreosis;
  • Having a life expectancy of less than one year, for other reasons than the congestive heart failure;
  • Unable to be followed-up in the scope of the study for geographical reasons;
  • Having refused to give their consent;
  • Minors (age < 18 years) and pregnant women.
