Determining Optimal Dose and Duration of Diuretic Treatment in People With Acute Heart Failure (The DOSE-AHF Study)

• Status: Completed
• Trial end date: 2010-02-01
• Target enrollment: 0
• Participant gender: All

Summary

Heart failure is a disorder in which the heart does not pump blood adequately. This can lead to several serious problems, including reduced blood flow throughout the body, congestion of blood in the veins and lungs, and fluid accumulation in various organs and limbs. Diuretics are often used to address the problem of fluid accumulation, but the optimal dose and the amount of time over which to administer each dose are unclear. This study will compare high and low doses of diuretics administered over longer and shorter periods of time to determine the safest and most effective combination.

• Phase: Phase 3

Criteria

Inclusion Criteria:

• Prior clinical diagnosis of heart failure that was treated with daily oral loop diuretics for at least 1 month

• Current diagnosis of heart failure, as defined by the presence of at least 1 symptom (dyspnea, orthopnea, or edema) AND 1 sign (rales on auscultation, peripheral edema, ascites, pulmonary vascular congestion on chest radiography)

• Daily oral dose of furosemide between 80 mg and 240 mg (or equivalent)

• Identified within 24 hours of hospital admission

Exclusion Criteria:

• Brain natriuretic peptide (BNP) less than 250 mg/mL or N-terminal prohormone brain natriuretic peptide (NT-proBNP) less than 1000 mg/mL

• Received IV vasoactive treatment or ultra-filtration therapy for heart failure since initial presentation

• Treatment plan during current hospitalization includes IV vasoactive treatment or ultra-filtration for heart failure

• Use of IV iodinated radiocontrast material within 72 hours prior to study entry or planned during hospitalization

• Enrollment or planned enrollment in another randomized clinical trial during this hospitalization

• Inability to comply with planned study procedures
