Abstract

Introduction: The most common symptom in heart failure (HF) is congestion, which can be refractory to diuretic treatment.

Aim: To verify whether, in patients with advanced HF and diuretic resistance, subcutaneous furosemide or furosemide in an oral solution can improve the clinical-analytical status.

Methods: From 2018 to 2020, 27 consecutive outpatients with diuretic resistance, not candidates for other alternatives, were recruited. Patients were treated either with subcutaneous furosemide in elastomeric pump (n: 10) or with oral solution (n: 17) for 5 days.

Results: The functional status (NYHA) improved with subcutaneous administration (predose: 3.8 ± 0.5 vs. postdose: 3.1 ± 0.7; p: 0.02) and oral solution (predose: 3.7 ± 0.3 vs. postdose: 2.5 ± 0.7; p: 0.0001). Weight loss was greater with the oral solution (predose: 85.5 ± 19.5 vs. postdose: 81.3 ± 18.8Kg; p: 0.0001) than subcutaneous (predose: 81.6 ± 15.9 vs. postdose: 80.4 ± 15.1kg; p: 0.16). Creatinine showed a non-significant increase in both groups. The number of hospital visits showed no difference between both options.

Conclusions: The administration of furosemide, both subcutaneously by elastomeric pump or drinking the oral solution, is effective for the treatment of congestion in advanced HF refractory to diuretic treatment.
