Brief Summary

Background: Acute decompensated heart failure (ADHF) is a common and potentially fatal cause of acute respiratory distress that requires immediate treatment in emergency department. The mortality rates are as high as 20% after discharge. Currently, furosemide is the most commonly used medicine in emergency department for ADHF. Although nitrate was proved to generate similar effect when compared to furosemide, less than 30% of patients received nitrates. This practice happens not only in Hong Kong, but also all around the world. Moreover, there is limited evidence to support a difference in ADHF patients receiving intravenous nitrate vasodilator therapy or alternative interventions. The aims of the study are:

  1. 1.To monitor the changes in concentration of cardiac biomarkers, VAS dyspnoea score and cardiac output before and after treatment of furosemide, isosorbide dinitrate or both.
  2. 2.To investigate whether the changes in concentration of cardiac biomarkers, VAS dyspnoea score and cardiac output before and after treatment is associated with the change in length of hospital stay.
  3. 3.To investigate whether combination treatment with intravenous furosemide and isosorbide dinitrate in patients with HF reduces VAS dyspnoea score, in-hospital mortality, length of hospital stay and number of readmission to a higher extend than do either medication alone.
  4. 4.To evaluate the prognostic values of novel cardiac biomarkers on 7-day, 14-day, 30-day and 6-month mortality and readmission.

Outcome Measures

Primary Outcomes (1)

  • The change in VAS dyspnoea score after randomized treatment

    Patients will be asked to indicate their status of dyspnoea using a visual analogue scale (VAS). They will be asked to make a mark on a 100 mm uncalibrated horizontal line in sitting (patients head at ≥ 600 relative to horizontal) and supine positions. The mark will be converted to a score (0-100 points) by measuring the distance from the left end. A VAS dyspnoea score of 0 corresponds to the patient's subjective feeling of "I can breathe normally" and a score of 100 represent to "I cannot breathe at all".

    24 hour after recruitment

Secondary Outcomes (5)

  • The changes in concentration of biomarkers (including BNP, NTproBNP, NGAL, hs-CRP and ST2) after randomized treatment

    24 hour after recruitment

  • The changes in volume of blood pumped by the ventricle per minute (cardiac output) after randomized treatment

    24 hour after recruitment

  • The number of in-hospital mortality

    An average of 5 days

  • Number of day stayed in hospital

    An average of 5 days

  • Number of mortality and readmission at 7-day, 14-day, 30-day and 6-month

    6-month after recruitment

Study Arms (3)

Group 1

ACTIVE COMPARATOR

Each patient will initially receive a 40 mg bolus of IV furosemide (10 mg/mL) and a 2 mL bolus of IV saline placebo, followed by IV saline placebo 6 mL/h

Drug: Furosemide

Group 2

ACTIVE COMPARATOR

Each patient will initially receive a bolus of IV saline placebo and a 2 mL bolus of IV isosorbide dinitrate (1 mg/mL), followed by IV isosorbide dinitrate 6 mL/h

Drug: Isosorbide Dinitrate

Group 3

ACTIVE COMPARATOR

Each patient will initially receive a 40 mg bolus of IV furosemide (10 mg/mL) and a 2 mL bolus of IV isosorbide dinitrate (1 mg/mL), followed by IV isosorbide dinitrate 6 mL/h

Drug: FurosemideDrug: Isosorbide Dinitrate

Interventions

Furosemide is the most commonly used medication for treatment of heart failure. It causes a direct vasodilator effect shortly after administration, followed by diuresis induction. However, furosemide also activates both the sympathetic and the renin angiotensin systems, causing a rise in peripheral resistance.

Also known as: Lasix
Group 1Group 3

Isosorbide dinitrate is a vasodilator which is also well-known for treating acute decompensated heart failure. It induces acute venodilatation at low dose and arteries dilation when gradually increasing the dose. The effect peaks 5 min after administration.

Also known as: Isoket
