ROAD-HF: RAAS Optimization for Acute CHF Patients
Study Details
Study Description
Brief Summary
Holding ACEI/ARBs during initial 72 hours of admission with acute decompensated heart failure may help preserve renal function with a lesser decline in GFR. This treatment modification will also allow the option of aggressive diuresis in volume overloaded CHF patients which should result in a lesser decline of AKI, length of stay, readmission rates, and cost associated with CHF treatment.

Detailed Description
The investigators hypothesize that worsening renal function can be mitigated by withholding ACEI/ARB during the initial phase of in-patient treatment with aggressive diuresis. This hypothesis will be tested by randomly allocating 360 admitted patients with ADHF on two treatment paths: 1) no ACEI/ARB administered for initial 72 hours of treatment during aggressive diuresis versus 2) full dose ACEI/ARB administered concurrently with aggressive diuresis in naïve patients/home dose, who are already on such therapy. The study team hopes to find that holding ACEI/ARBs during the initial 72 hours of admission with acute decompensated systolic heart failure will help preserve renal function, as demonstrated by a lesser decline in GFR. In addition, this treatment would allow the option of aggressive diuresis in volume overloaded CHF patients, resulting in a lesser decline of AKI, length of stay, readmission rates, and costs associated with CHF treatment. By understanding the complex interaction between holding ACEIs/ARBs and continued aggressive diuresis, the investigators intend to develop optimal dosing strategies for acute, decompensated CHF patients, further minimizing adverse events such as electrolyte issues and declining GFR/AKI.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| No Intervention: Full Dose ACEI/ARB or Home Dose Group This group will receive the full dose of ACEI/ARBs. |
|
| Active Comparator: No ACEI/ARB Group This group will not receive the full dose of ACEI/ARBs for the first 72 hours of hospitalization. |
Other: Change of treatment plan
Withholding ACEI/ARBs during initial 72 hours of admission with acute decompensated heart failure may help preserve renal function with a lesser decline in GFR. This treatment modification will also allow the option of aggressive diuresis in volume overloaded CHF patients which should result in a lesser decline of AKI, length of stay, readmission rates, and cost associated with CHF treatment.

Outcome Measures
Primary Outcome Measures
- Serum Creatinine Levels [Baseline, 24 hours, 48 hours, 72 hours]
Change in serum creatinine from randomization. (AKI is defined as an increase in the serum creatinine level of more than 0.3 mg per deciliter over 48 hours)
- Patient Global Assessment (well-being) over 72 hours [0 hours, 24 hours, 48 hours, 72 hours]
Patient global assessments by modified scale (based on Borg and VAS) for 0, 24, 48, 72 hours. Scaled 1 - 10. A "1" means the patient feels the best they've ever felt and a "10" means the participant feels the worst they have ever felt. Following all time points collected, the area under the curve for global assessment over the first 72 hours will be a primary efficacy endpoint (AUC for PGA). For patient well-being (PGA) 1 Best I've ever felt 2 3 Feeling good 4 5 Feeling okay 6 7 Feeling bad 8 9 Feeling terrible 10 Worst I've ever felt
- Dyspnea (shortness of breath) clinical change over 72 hours [0 hours, 24 hours, 48 hours, 72 hours]
Patient dyspnea assessments by modified scale (based on Borg and VAS) for 0, 24, 48, 72 hours. Scaled 1 - 10. A "1" means no shortness of breath and a "10" means the patient can't breathe at all. Following all time points collected, the area under the curve for dyspnea assessment over the first 72 hours will be a primary efficacy endpoint (AUC for dyspnea). For shortness of breath (SOB) 1 No SOB at all 2 3 Slight SOB 4 5 Moderate SOB 6 7 Severe SOB 8 9 Extreme SOB 10 "I can't breathe!"
- Kinetic EGFR Levels [Baseline, 24 hours, 48 hours, 72 hours]
Change in kinetic EGFR from baseline to 24, 48, and 72 hours.
Secondary Outcome Measures
- Weight Change [Baseline, 24 hours, 48 hours, 72 hours]
Change in patient's weight over 3 day period.
- Negative Fluid Balance [Baseline, 24 hours, 48 hours, 72 hours]
Changes in net fluid loss over 24, 48, 72 hours.
- CHF Clinical Change [Baseline, 72 hours]
Change in signs and symptoms of congestion (defined as jugular venous pressure of <8 cm, with no orthopnea and with trace peripheral edema or no edema) from baseline to 24, 48, 72 hours.
- Change in Renal Function [Baseline, 48 hours]
Renal biomarker (NephroCheck) levels at baseline and 48 hours. All patients receive baseline NephroCheck, and 48 hour re-assessment is limited to the first 100 patients.
- Number of patients experiencing CHF Treatment Failure [Over 72 hours]
Persistent or worsening heart failure requiring additional interventions. Patients requiring other intravenous vasoactive medications for heart failure (inotropes, vasodilators, etc) for clinical reasons during the randomization period will meet the secondary endpoints of "worsening or persistent heart failure" and "treatment failure." Patients deemed to have a clinical need for additional diuretics during the study period will be permitted to receive diuretics. This will be captured as "rescue therapy" and will meet criteria for secondary endpoints of "worsening or persistent heart failure" and "treatment failure" endpoints. Conversely, patients may develop signs or symptoms of over-diuresis (such as hypotension) that will necessitate holding or discontinuing diuretics before completion of the randomization period. This will be captured as a "treatment failure" if it requires specific intervention beyond simply holding diuretics.
- Hospitalization LOS [Total stay during current admission]
Length of inpatient stay
- Cost Analysis [Total stay during current admission]
Cost of inpatient stay during admission.
- Number of patient mortality [30 days]
Death within 30 days of current inpatient stay (from first day of admission)
- Number of patients readmitted or experiencing a ED visit [30 days]
Readmission or ED visit at UF Health within 30 days of current inpatient stay (from first day of admission)
- Number of patients readmitted over one year [1 year]
Readmission at UF Health within 1 year of current inpatient stay (from first day of admission)
