Effects of the Beta-Adrenoceptor Blocker Carvedilol in Children with Myocardial Failure
We performed a prospective, open study to evaluate the clinical effect of Carvedilol among pediatric patients with myocardial failure (CHF) failing to reply sufficiently to standard therapy. In addition, we as...

Pharmacological aspects of calcium channel blockers
Calcium channel blockers (CCBs) inhibit voltagedependent L-type calcium channels. This leads to vascular smooth muscle relaxation and negative inotropic and chronotropic effects in the heart. The latter are co...

Receptor-Mediated Regulation of Cardiac Contractility: lnotropic Effects of Alpha-Adrenoceptor Stimulation with Phenylephrine and Noradrenaline in Failing Human Hearts
In the failing human heart, the beta-adrenergic positive inotropic effect (PIE) is attenuated. It is conceivable that in compensation alpha-adrenoceptor-mediated inotropism may gain importance under these cond...

Introduction: Mechanisms of positive inotropic effects
This review deals with the principal mechanisms which are known to play a role in positive inotropism: 1) The myoplasmic Ca2+ concentration may be increased by increases in cyclic AMP. Beside receptor-mediated st...
