E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective is to assess the effects of Mirabegron on left ventricular systolic function in patients with moderate to severe chronic heart failure. |
Formålet med studiet er at undersøge effekten af Mirabegron på venstre ventrikels systoliske funktion ved moderat til svær hjertesvigt. |
|
E.2.2 | Secondary objectives of the trial |
In patients with moderate to severe heart failure: 1. Determine safety of administration of Mirabegron. 2. Determine if treatment with Mirabegron for 6 months induces beneficial cardiac structural remodeling. 3. Determine if Mirabegron improves symptoms and exercise capacity as indicated by questionnaires and 6 min walk test. 4. Determine effects of Mirabegron on cardiac conduction, repolarisation and rhythms and arrhythmias. 5. Determine effects of Mirabegron on circulating biomarkers. 6. Determine the immediate haemodynamic effects of Mirabron as measured invasively.

Hos ateister med moderat til svær hjertesvigt: 1. Undersøge sikkerheden af at bruge Mirabegron 2. Undersøge om behandling med Mirabegron i 6 måneder medfører en gavnlig remodellering. 3. Undersøge om Mirabegron forbedrer symptomer samt arbejdskapacitet bedømt ved 6 minutters gangtest. 4. Undersøge MIrabegrons effekt på overledning, repolarisering, rytme og arytmier. 5.
