clenbuterol and Prosthesis Durability

clenbuterol has been researched along with Prosthesis Durability in 1 studies

Clenbuterol: A substituted phenylaminoethanol that has beta-2 adrenomimetic properties at very low doses. It is used as a bronchodilator in asthma.
clenbuterol : A substituted aniline that is 2,6-dichloroaniline in which the hydrogen at position 4 has been replaced by a 2-(tert-butylamino)-1-hydroxyethyl group.

Mean Change in EuroQoL Visual Analog Scale (EQ5D-VAS) From Baseline to 6 Months and 1 Year Following Device Implant

Scale 0 - 100 where 0 is worst possible health state and 100 is perfect health. (NCT00585546)
Timeframe: 1 year following LVAD implantation

Interventionunits on a scale (Mean)
6 months post implant12 months post implant
