简要总结
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.
详细描述
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.

结局指标
主要结局
Dyspnea (shortness of breath) clinical change over 72 hours
时间窗: 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!"
Patient Global Assessment (well-being) over 72 hours
时间窗: 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
Serum Creatinine Levels
时间窗: 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)
Kinetic EGFR Levels
时间窗: Baseline, 24 hours, 48 hours, 72 hours
Change in kinetic EGFR from baseline to 24, 48, and 72 hours.
