Arms Assigned Interventions
Experimental: 1
Two experimental and/or intervention groups under 1 arm.
Device: Insignia Plus / Ultra (Guidant/Boston Scientific)
Cardiac pacing using any Guidant/Boston Scientific Implantable Pacemaker System with rate-modulation and any compatible intracardiac lead system.
Other Name: Guidant or Boston Scientific implantable pacemakers

Detailed Description:
RESET is a multicenter trial that will assess the effect of pacing in heart failure patients with a normal ejection fraction (or diastolic heart failure). The purpose of the RESET study is to evaluate the effect of pacing on exercise capacity and quality of life in this heart failure population.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients who are in sinus rhythm
  • Patients who are on stable medical therapy
  • Patients who exhibit signs and symptoms of heart failure, NYHA Class II or III
  • Patients who have experienced a hospitalization for decompensated heart failure; treatment for pulmonary congestion or volume overload; chronic treatment with a loop diuretic; or a BNP > 125 ng/l.
  • Left ventricular ejection fraction ≥ 50%

Exclusion Criteria:

  • Patients with persistent atrial fibrillation or atrial flutter
  • Patients who are in complete heart block
  • Patients who have experienced a recent MI or have unstable angina or require cardiac surgery or other procedures
  • Patients who have severe heart valve disease or valve replacement
  • Patients with a contraindication for a pacemaker system
  • Patients who have a neuromuscular, orthopedic or other non-cardiac condition that prevents patient from exercise testing
  • Patients who have infiltrative or hypertrophic cardiomyopathy
  • Patients who have known severe pulmonary disease
  • Patients with uncontrolled diabetes or blood pressure (SBP > 160 mmHg or DBP > 95 mmHg)
