Alternative in Beta Blocker Intolerance: The ABBI Trial (ABBI)

July 29, 2019 updated by: Minneapolis Heart Institute Foundation

Alternative in Beta Blocker Intolerance; the ABBI Trial

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.

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.
