Symptomatic achievements with diuretics in congestive heart failure

Area of Science:

• Cardiology
• Pharmacology

Background:

• Severe heart failure significantly impacts patient quality of life and prognosis.
• Loop diuretics are a cornerstone in managing fluid overload in heart failure.

Purpose of the Study:

• To compare the short-term clinical efficacy of furosemide and torasemide in patients with severe heart failure.
• To evaluate the impact of these diuretics on symptoms, exercise tolerance, and hemodynamic parameters.

Main Methods:

• An open-label study involving 24 patients with severe heart failure, divided into two groups.
• Patients received either furosemide (25 mg/day) or torasemide (10 mg/day) for 8 days, added to baseline digoxin treatment.
• Clinical status was assessed by symptom improvement, exercise tolerance (total body oxygen consumption), pulmonary congestion (radiography), and right heart filling pressure (jugular venous pressure).

Main Results:

• Both furosemide and torasemide demonstrated similar, substantial, and significant improvements in patient symptoms and exercise tolerance.
• Both diuretics led to significant reductions in pulmonary congestion and right heart filling pressure.
• No significant differences in efficacy were observed between the two loop diuretics.

Conclusions:

• Furosemide and torasemide exhibit comparable short-term clinical efficacy in managing severe heart failure.
• Both agents provide significant benefits in improving clinical status and exercise capacity.
• These findings support the use of either furosemide or torasemide for short-term management of severe heart failure.
