Hemodynamic effects of celiprolol in patients with ischemic and non-ischemic cardiomyopathy

In this study, the effect of celiprolol (beta-1-antagonist with beta-2-agonistic activity) on hemodynamic and electrocardiographic parameters of patients with congestive heart failure due to ischemic (iCMP) and non-ischemic (niCMP) origin should be evaluated. Sixteen patients were included into the study, nine with iCMP, seven with niCMP. All patients were investigated by radionuclide ventriculography (99mTc), right heart floating catheterization, and late potential analysis and measurement of heart rate variability. All patients received 200 mg celiprolol after a 3-day period of 100 mg celiprolol/day. All patients showed, after a follow-up period of 3 months, a significant improvement of the left ventricular ejection fraction. The changes of hemodynamic parameters were more pronounced in patients with niCMP. Heart rate did not decrease in patients with niCMP. A 3-month therapy with celiprolol as an additional therapy to a preexisting heart failure therapy leads to a significant improvement of the ejection fraction in patients with congestive heart failure. Patients with niCMP seemed to profit more from this additional beta-blocking therapy.
