However, there is some debate concerning the risk, benefit, and appropriate use of higherdose diuretics. There is also an absence of prospective studies and trial evidence to provide clinicians with consistent guidelines for diuretic management. In light of current uncertainty pertaining to the appropriate administration and dosing of diuretics, DOSE-AHF investigators set out to evaluate the safety and efficacy of two administration (bolus Q 12 hours vs continuous infusion) and two dosing (low intensification of 1 x chronic daily oral dose furosemide vs high intensification of 2.5 x chronic daily oral dose furosemide) strategies.\u003C\/p\u003E\n         \u003Cp id=\u0022p-4\u0022\u003EDOSE-AHF was a double-blind, randomized trial with a 2\u00d72 factorial design that included 308 patients with prior clinical diagnosis of acute heart failure (AHF; defined by at least one symptom and one sign) who were identified within 24 hours of hospital admission. All patients were taking oral furosemide 80 mg to 240 mg daily with an anticipated need for IV loop diuretics for at least 48 hours. Patients were excluded from participation if they received or planned to receive IV vasoactive therapy or ultrafiltration therapy for HF; had acute coronary syndrome within 4 weeks; and had systolic blood pressure \u0026lt;90 mmHg, serum creatinine\u0026gt;3.0 mg\/dL at baseline, B-type natriuretic peptide (BNP) \u0026lt;250 pg\/mL, or N-terminal pro-BNP (NT-proBNP) \u0026lt;1000 pg\/mL.\u003C\/p\u003E\n         \u003Cp id=\u0022p-5\u0022\u003EThe coprimary endpoints were the efficacy endpoint of patient global assessment by visual analog scale (VAS) over 72 hours using area under the curve (AUC) and the safety endpoint of renal function assessment, defined as change in creatinine from baseline to 72 hours. The study was 88% powered for detecting a creatinine difference of 0.2 mg\/dL and a 600-point difference in VAS. Statistical significance for the two primary endpoints was p\u22640.25.

Though transient changes in renal function occurred in patients who received high-intensification therapy prior to 60 days, the difference between the two groups dissipated by Day 60.
