Combination Diuretic Therapy for Acute Decompensated Heart Failure

Phase 4
Withdrawn
Conditions
Acute Decompensated Heart Failure
Interventions
Registration Number
NCT05840536
Lead Sponsor
Ochsner Health System
Brief Summary

Patients with heart failure are often admitted to the hospital because they have accumulated excessive amounts of fluid, they become short of breath and congested with fluid. Removing the excess fluid is necessary to improve the patients symptoms and reduce the risk of being re-admitted to the hospital. Diuretics ("water pills") are often given through an IV to accelerate the fluid removal. Furosemide is commonly used for fluid removal, however some patients do not respond well to the medication. There are other diuretics available that can work in conjunction with furosemide and increase the rate of fluid removal. The other "water pills" have slightly different mechanisms of action in the body compared to furosemide and when combined they may increase fluid removal.

The investigators hypothesize that adding chlorothiazide to furosemide will result in quicker and more effective fluid removal in heart failure patients.

Detailed Description

The investigators will randomly assign patients to receive either furosemide alone or furosemide in combination with chlorothiazide when they are admitted to the hospital with acute heart failure and excessive volume.

All patients will be monitored for rate of fluid removal, improvement in symptoms, and side-effects of the medications.

GroupInterventionDescription
Combination Diuretic TherapyFurosemide plus ChlorothiazidePatients will receive lasix infusion starting at 5mg/hr along with a bolus dose of chlorothiazide 250mg at the initiation of the protocol. The lasix infusion can be titrated to 10mg after 12hrs based on volume of diuresis. This arm will also receive 250mg bolus doses of chlorothiazide every 12hrs for the duration of the study.
Monotherapy DiureticFurosemidePatients will receive furosemide infusion at 5mg/hr along with an initial bolus dose of furosemide equal to twice their home oral dose. The furosemide infusion can be increased to 10mg/hr after 12hrs based on urine output. This arm will receive bolus doses of furosemide every 12hrs equal to twice their home oral dose until completion of the protocol.
