Brief Summary
Background: Intravenous (IV) loop-diuretics have been a key component in treating pulmonary edema since the nineteen sixties and has a Class 1 recommendation in the 2021 European Society of Cardiology guidelines for heart failure. Conversely, vasodilation was downgraded in the treatment of acute heart failure due to a lack of trials that compare vasodilation with loop-diuretics in a hyperacute clinical setting. This clinical equipoise will be tested in a trial including patients with pulmonary congestion immediately at hospital admission. Primary objective: To determine the superior strategy of loop-diuretics (furosemide), vasodilation (nitrates) or the combination during emergency treatment. Design: Investigator-initiated, randomized, double-blinded, placebo-controlled trial with 1:1:1 allocation. Intervention: Intervention-phase will last 6 hours from study-inclusion, and patients will be allocated to one of three groups: * Boluses of 40 mg IV furosemide + nitrate-placebo as soon as possible and repeated up to 10 times. * Boluses of 3 mg IV isosorbide dinitrate + furosemide-placebo as soon as possible. * Boluses of both 3 mg IV isosorbide dinitrate + of 40 mg as soon as possible.
Eligibility Criteria
Inclusion criteria 1. Age ≥ 18 years 2. Acute (within minutes to days) onset or worsening of subjective dyspnea\* 3. Systolic blood pressure ≥100 mmHg 4. Oxygen saturation \<94% or need of oxygen 5. Signs or suspicion of congestion (peripheral edema, rales, and/or clinical suspicion of congestion) \* * by the best assessment from a medical doctor. Inclusion must not wait on x-ray or other measures: patients suspected of pulmonary congestion should be included immediately. Exclusion criteria 1. More than 40 mg IV furosemide within the last three hours before randomization including prehospital treatment. 2. More than 3 hours from hospital-admission to randomization 3. Ongoing ventricular taky- or brady-arrythmias or supraventricular arrhythmias with HR \> 180 or \< 40 bpm. 4. Suspected severe infection or sepsis. Exclusion criteria are purposely liberal, so patients can be included in accordance with everyday clinical practice. However, a safety criterion will be implemented: If blood p
