Does carvedilol improve symptoms, exercise, ejection fraction, and oxidative stress compared to metoprolol in patients with heart failure?
Carvedilol and metoprolol provide similar benefits on symptoms, exercise capacity, ejection fraction, and oxidative stress over 6 months in patients with heart failure.
Carvedilol and metoprolol showed parallel beneficial effects in the measured parameters over 6 months, with no relevant between-group differences in this heart failure population.
Kukin et al. (1999) studied this question.
