Hypertonic Saline Therapy in Ambulatory Heart Failure Unit.

Phase 3
Completed
Conditions
Heart Failure
Interventions
Drug: Hypertonic saline solution plus intravenous furosemide
Registration Number
NCT04533997
Lead Sponsor
Puerta de Hierro University Hospital
Brief Summary

The purpose of this study is to compare intravenous furosemide (125 to 250 mg), isolated or in combination with hypertonic saline solution (2.6% to 3.4%) in the outpatient heart failure patient. The hypothesis is that the combination therapy will increase the diuresis volume at 3 hours and improve congestion parameters at 7 days.

Detailed Description

This is a randomized, double-blind, multicenter study of all consecutive patients with decompensated heart failure and signs of volume overload who do not require hospital admission but require intravenous diuretic for relief of congestion.

Patients meeting the inclusion criteria, with prior informed consent, will be randomized to treatment with furosemide with hypertonic saline versus isolated furosemide (control group).

Complete clinical evaluation, echocardiography, and blood and urinary tests will be performed before the treatment. After 3 hours, diuresis volume, weight and urinary parameters will be evaluated. Efficacy and safety visits will be performed at 7 and 30 days.
