Further study details as provided by Ohio State University:

Primary Outcome Measures:
  • Assess the impact of chronic mitral regurgitation (MR) on neurohormonal activation, left ventricular remodeling, function and reserve in patients with or without surgery. Determine the effect of beta-blockade previously mentioned markers of MR. [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Test new noninvasive methods to assess global and regional myocardial contractility in chronic MR, correlating the results with biochemical markers. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 66
Study Start Date: October 2007
Estimated Study Completion Date: July 2010
Estimated Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions

Patients who have may or may not of been surgically treated for mitral regurgitation that start Beta-Blocker therapy.
Drug: Beta-blocker therapy (TOPROL-XL® )
Patients who have been surgically treated for mitral regurgitation that start Beta-Blocker therapy.

Detailed Description:

The purpose of this study tests whether Toprol xl, a beta-blocker drug, will benefit patients with chronic mitral regurgitation after mitral valve surgery and to investigation effects of chronic mitral regurgitation on heart size, heart function, exercise capacity and clinical symptoms.
