In this study the investigators will assess the tolerance of Nebivolol (Bystolic) in cardiovascular patients who are not able to tolerate conventional beta blockers. A side effect profile will be tracked and compared with previous beta blocker use.

The investigators hypothesize that Bystolic will be tolerated by many patients who are intolerant of conventional blockers.

Condition Intervention Phase

Further study details as provided by Minneapolis Heart Institute Foundation:

Primary Outcome Measures:
  • Incidence of intolerance of Bystolic, measured by side effect(s) that lead to discontinuance of Bystolic by the patient and/or the physician [ Time Frame: 30 Days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Reason for termination of Bystolic [ Time Frame: 30 Days ] [ Designated as safety issue: No ]
  • Incidence of same symptom stopping Bystolic as previous beta blocker [ Time Frame: 30 Days ] [ Designated as safety issue: No ]
  • Symptom severity [ Time Frame: 30 Days ] [ Designated as safety issue: No ]

Enrollment: 6
Study Start Date: May 2009
Study Completion Date: June 2012
Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Nebivolol Drug: Nebivolol
Bystolic (Nebivolol), 5 mg per day for 30 days, titrated up to 10 mg at 2 weeks if necessary for blood pressure control.
Other Name: Bystolic

Detailed Description:
Patients who have been prescribed standard beta blockers but were unable to tolerate them due to side effects will be studied. They will take a new beta blocker, Nebivolol (Bystolic) for 30 days, if tolerated. Side effects will be tracked and compared to previous.
