E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
We want to explore whether inhaled furosemide relieves breathlessness in patients with heart failure. To address this question we first need to conduct a pilot study. This pilot study will inform a future clinical trial to test the benefit of adding inhaled furosemide to existing treatment in advanced heart failure patients.
The principle research question: - What is the effect on inhaled furosemide on breathlessness in patients with chronic advanced heart failure?
Why ask this question? Patients with heart failure often experience breathlessness/dyspnoea which restricts their activities. Furosemide is a prescription drug taken as a tablet or as an injection which makes kidneys produce more urine to remove fluid build-up in heart failure. Over time a third of patients will need more furosemide to get the same response from the kidneys but high level of furosemide can lead to kidney failure. If furosemide is inhaled instead this is known to stop coughing, protect the airwa |

E.2.2 | Secondary objectives of the trial |
To ensure that the most reliable future clinical trial the following factors will be addressed: i) assess how much furosemide gets absorbed from the lungs into the blood ii) determine the effect of inhaled furosemide on breathlessness with exercise iii) assess the effect of furosemide on blood tests which best monitor heart failure before and after exercise iv) Assess the effect of inhaling furosemide when applying different breathing patterns (shallow, fast breaths versus slow, deep breaths) Can the study answer it? At each visit the patients will i)have a blood test before and after the mist to see how much furosemide is absorbed into the blood ii)perform full cardiopulmonary exercise tests (cycle) or a 6-minute walk test iii)have a blood tests looking at markers of heart failure before and after mist inhalation and exercise iv) inhaled the mist with either fast, shallow breaths or slow, deep breaths. Each patient will do 2 visits with fast, shallow breaths (one with e |

E.3 | Principal inclusion criteria |
1)Patient is willing and able to give informed consent for participation in the trial. 2)Male or Female, aged 18 years or above.

E.5 End points |
E.5.1 | Primary end point(s) |
Visual analogue scale (VAS) ratings of ‘air hunger’during experimentally induced breathlessness with total score on Dyspnoea 12 questionnaire |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
12 patients completing 4 visits each, at least 1 week apart. Each patient will perform a breathlessness twice on each visit, once before and once after inhalation of the mist (furosemide or saline). A total of 8 breathlessness tests over the course of the study for each patient. |
|
E.5.2 | Secondary end point(s) |
i) to discover which breathing pattern should be used to inhale furosemide – fast, shallow or slow, deep breaths. ii) to find out how much furosemide gets absorbed from the lungs into the blood iii) to investigate whether full cardiopulmonary exercise tests can be used to monitor the benefit of inhaled furosemide in heart failure patients in place of usual 6-minute walk tests, iv) to discover which blood tests best monitor heart failure before and after inhaled furosemide v) to test whether experimentally induced breathlessness can be used to measure breathlessness sensitivity in heart failure patients rather than standard exercise tests.

E.5.2.1 | Timepoint(s) of evaluation of this end point |
12 patients completing 4 visits each, at least 1 week apart. Each patient will perform a breathlessness test and an exercise test twice on each visit, once before and once after inhalation of the mist (furosemide or saline). A total of 8 breathlessness tests and 8 exercise tests over the course of the study for each patient. Each visit they will have 5 blood samples withdrawn from their cannula and their urine volume measured on two occasions after the mist inhalation. |
