The majority of patients with chronic congestive cardiac failure will need diuretics to control their symptoms and signs of pulmonary and systemic venous congestion (1)
The combination of a thiazide, such as bendrofluazide or metolazone, with a loop diuretic promotes an intense diuresis which may be required for patients with severe heart failure
Spironolactone is a potassium-sparing diuretic which improve prognosis when given to patients with chronic heart failure.
In HF patients with preserved left ventricular ejection fraction (HFPEF), low to medium dose of loop diuretics (e.g. – less than 80mg of furosemide per day) has shown to be helpful. People whose heart failure does not respond to this treatment will need further specialist advice (4)
