Figure 6 The effects of exogenously administered norepinephrine (0.4 µg/kg/min) before (dilated cardiomyopathy [DCM]) and after 3 days of treatment with carvedilol (DCM+C) or metoprolol controlled release/extended release (DCM+M) on cardiac output (CO), stroke volume (SV), systemic vascular resistance (SVR), and characteristic aortic impedance. The indicated p values represent the differences in the carvedilol responses and metoprolol responses by analysis of variance.
