Figure 1 Time-dependent improvement of left ventricular ejection fraction (LVEF) with carvedilol (n = 14, black circles) or metoprolol (n = 16, open circles) in dilated cardiomyopathy patients with persistent left ventricular dysfunction despite chronic optimum treatment including angiotensin-converting enzyme inhibitors and metoprolol. *p = 0.033, 12 months vs. baseline carvedilol; p = 0.046, 12 months carvedilol vs. metoprolol.
