Clinical Trial Summary

This is a randomized, double-blind, crossover study in healthy adult subjects. Each subject will receive a single dose of bisoprolol 5 mg p.o. and nebivolol 5 mg p.o. with 1 week washout period. All subjects will undergo a physical examination, 12-lead electrocardiography and a comprehensive echocardiographic study before the administration of the study drug and 5 hours thereafter.

Secondary Absolute and relative changes of left ventricular ejection fraction (%) Ejection fraction will be measured using modified Simpson rule Pre- and 5 hours post study drug administration
Secondary Absolute and relative changes of global longitudinal strain (%) Global longitudinal strain will be assessed using speckle tracking echocardiography Pre- and 5 hours post study drug administration
Secondary Absolute and relative changes of myocardial work (%) Myocardial work will be assessed by using a dedicated commercially available software (GE, Norway) Pre- and 5 hours post study drug administration
Secondary Absolute and relative changes of atrial function (ml) Atrial function will be assessed by measuring phasic volume changes during diastole Pre- and 5 hours post study drug administration
Secondary Absolute change of myocardial dispersion (ms) Myocardial dispersion will be assessed by using speckle tracking echocardiography Pre- and 5 hours post study drug administration
