Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To assess the effects on measures of lung and heart function of two different beta blockers - one that acts mainly on the heart and the other that acts on both the heart and lungs - after chronic dosing.; Secondary Objective: To assess how beta blockers interact with standard COPD inhaler treatment. To assess how well beta blockers are tolerated in COPD using gradually increasing doses over several weeks. To assess what protection is given by the inhaler Tiotropium against worsening of lung function in the early stages of the beta blocker treatment. ;Primary end point(s): The null hypothesis proposed is there is no difference between cardioselective (bisoprolol) and non-cardioselective (carvedilol) beta blockade, with chronic dosing, in terms of change in airway resistance at 5Hz (R5), using Impulse Oscillometry, from baseline.;Timepoint(s) of evaluation of this end point: At baseline and end of 4th, 5th and 6th weeks of each (of two) treatment periods. | — |
