Trial Review

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
On Day 1, in patients that are clinically considered be suffering from oedema secondary to acutely decompensated congestive heart failure or pulmonary hypertension, following the administration of an IV bolus dose of frusemide (typically 40mg), a series of blood (5mL) and urine samples will be collected at t= 0, 1, 2, 3, 4, 5 and 6hrs for analysis of frusemide concentrations. On Day 2 (acutely decompensated phase) following the administration of an oral bolus dose of frusemide (double the Day 1 IV dose; typically 80mg), a series of blood (5mL) and urine samples will be collected at t= 0, 1, 2, 3, 4, 5 and 6hrs for analysis of frusemide concentrations. In patients presenting with oedema secondary to acutely decompensated heart failure, five to seven days later, on Day E-1 when the patient is clinically considered to no longer be acutely decompensated (i.e. they have returned to compensated heart failure) following the administration of an IV bolus dose of frusemide (typically 40mg), a series of blood (5mL) and urine samples will be collected at t= 0, 1, 2, 3, 4, 5 and 6hrs for analysis of frusemide concentrations. On Day E (compensated phase) following the administration of an oral bolus dose of frusemide (double the Day E-1 IV dose; typically 80mg), a series of blood (5mL) and urine samples will be collected at t= 0, 1, 2, 3, 4, 5 and 6hrs for analysis of frusemide concentrations.

Eligibility
Key inclusion criteria
Adult males and females over the age of 18 years being treated for either acutely decompensated congestive heart failure or pulmonary hypertension by the appropriate physician specialists.

Potential study participants will be enrolled into the respective arms of the study (acutely decompensated congestive heart failure or pulmonary hypertension) on the basis of clinician assessment of the following variables:

Acutely decompensated congestive heart failure referred from the cardiology clinic:
* Documented reduced ejection fraction (<45%).
* Presence of at least one symptom (dyspnoea, orthopnoea, fatigue or oedema) and
* Presence of at least one sign (rales, peripheral oedema, ascites, or pulmonary vascular congestion on chest radiography) of heart failure.

Pulmonary hypertension referred from the pulmonary hypertension clinic and requiring frusemide to alleviate the congestion caused by right heart failure:
* Documented elevation of pulmonary arterial pressures (either noninvasively by echocardiogram or invasively by right heart catheterization) >25 mmHg
* Documented normal ejection fraction (>50%), and
* Presence of at least one sign (lower limb oedema or ascites) of pulmonary hypertension.

Compensated heart failure will be recognised by:
* The assessment of the treating clinical team but should include: improvement of the principal symptom and improvement in signs of decompensated CHF
