Ambulatory intravenous furosemide for decompensated heart failure: safe, feasible, and effective.

ABSTRACT:

Aims

This study aims to establish the feasibility, safety, and efficacy of outpatient intravenous (IV) diuretic treatment for the management of decompensated heart failure (HF) for patients enrolled in the HeartFailure@Home service.

Methods and results

We retrospectively analysed the clinical episodes of decompensated HF for patients enrolled in the HeartFailure@Home service, managed by ambulatory IV diuretic treatment either at home or on a day-case unit. A control group consisting of HF patients admitted to hospital for IV diuretics (standard-of-care) was also evaluated. In total, 203 episodes of decompensated HF (n = 154 patients) were evaluated. One hundred and fourteen episodes in 79 patients were managed exclusively by the ambulatory IV diuretic service-78 (68.4%) on a day-case unit and 36 (31.6%) domiciliary; 84.1% of patient episodes under the HF@Home service were successfully managed entirely in an out-patient setting without hospitalization. Eleven patients required admission in order to administer higher doses of IV diuretics than could be provided in the ambulatory setting. During follow-up, there were 20 (17.5%) 30 day re-admissions with HF or death in the ambulatory IV group and 29 (32.6%) in the standard-of-care arm (P = 0.02). There was no difference in 30 day HF readmissions between the two groups (14.9% ambulatory vs. 13.5% inpatients, P = 0.8), but 30 day mortality was significantly lower in the ambulatory group (3.5% vs. 21.3% inpatients, P < 0.001).

Conclusions

Outpatient ambulatory management of decompensated HF with IV diuretics given either on a day case unit or in a domiciliary setting is feasible, safe, and effective in selected patients with decompensated HF. This should be explored further as a model in delivering HF services in the outpatient setting during COVID-19.

Project description:AimsWe sought to compare the effects of furosemide + hypertonic saline solution (HSS) treatment in patients with acute decompensated heart failure in comparison with furosemide alone and the response in a compensated state after an acute saline load with regard to serum levels of heart failure biomarkers.Methods and resultsWe enrolled 141 patients with acute decompensated heart failure with reduced ejection fraction admitted to our Internal Medicine ward from March 2017 to November 2019. A total of 73 patients were randomized to treatment with i.v. high-dose furosemide plus HSS, whereas 68 patients were randomized to i.v. high-dose furosemide alone. Patients treated with furosemide plus HSS compared with controls treated with furosemide alone showed a comparable degree of reduction in the serum levels of interleukin (IL)-6, soluble suppression of tumorigenicity 2 (sST2), and N-terminal pro-brain natriuretic peptide (NT-proBNP) in the 'between-group' analysis. Nevertheless, patients treated with high-dose furosemide + HSS showed significantly higher absolute delta values of IL-6 (2.3 ± 1.2 vs. 1.7 ± 0.9, P < 0.0005, and 2.0 ± 0.8 vs. 1.85 ± 1.1, P = 0.034), sST2 (41.2 ± 8.6 vs. 27.9 ± 7.6, P < 0.0005, and 37.1 ± 6.6 vs. 28.4 ± 6.7, P < 0.0005), high-sensitivity troponin T (0.03 ± 0.02 vs. 0.02 ± 0.01, P = 0.001, and 0.03 ± 0.02 vs. 0.02 ± 0.01, P = 0.009), NT-proBNP (7237 ± 7931 vs. 3244 ± 4159, P < 0.005, and 5381 ± 4829 vs. 4466 ± 4332, P = 0.004), and galectin-3 (15.7 ± 3.2 ng/mL vs. 11.68 ± 1.9 ng/mL, P < 0.0005, and 16.7 ± 3.9 ng/mL vs. 11.8 ± 2.4 ng/mL, P < 0.0005) than patients treated with furosemide alone. After acute saline load, patients treated with i.v. furosemide + HSS in comparison with subjects treated with furosemide alone showed a significantly lower increase in the serum concentrations of IL-6 (-0.26 ± 0.42 pg/mL vs. -1.43 ± 0.86 pg/mL, P < 0.0005), high-sensitivity troponin T (0 vs. -0.02 ± 0.02 ng/mL, P < 0.0005), sST2 (-8.5 ± 5.9 ng/mL vs. -14.6 ± 6.2 ng/mL, P < 0.0005), galectin-3 (-2.1 ± 1.5 ng/mL vs. -7.1 ± 3.6 ng/mL, P < 0.0005), and NT-proBNP (77 ± 1373 vs. -1706 ± 2259 pg/mL, P < 0.0005).ConclusionsOur findings concerning a comparable degree of reduction in the serum levels of three cardinal biomarkers indicate that a reduction in serum heart failure markers is not linked to the higher degree of congestion relief with a more rapid achievement of a clinical compensation state. This issue may have possible benefits on clinical practice concerning its therapeutic effects over and beyond the simple amelioration of clinical congestion signs and symptoms. Nevertheless, our findings of higher delta values after treatment with i.v. furosemide plus HSS indicate a possible higher efficacy by means of modulation of the stretching and fibrosis mechanisms.
