Limitations
The present study was associated with several limitations. First, this
was a non-randomized, retrospective study. Second, the small number of
patients with AF may have influenced the interpretation of the results.
Third, asymptomatic AF episodes may have been missed after CA. Fourth,
there are no uniform standards for introducing bepridil. Finally, the
duration of bepridil use was left to the discretion of the individual
physicians in outpatient clinics. Thus, a prospective, randomized
controlled study is needed to confirm these findings.
