The Editorial Executive Committee welcomes letters, which should be less than 250 words. Before a decision to publish is made, letters which refer to a published article may be sent to the author for a response. Any letter may be sent to an expert for comment. When letters are published, they are usually accompanied in the same issue by their responses or comments. The Committee screens out discourteous, inaccurate or libellous statements. The letters are sub-edited before publication. Authors are required to declare any conflicts of interest. The Committee's decision on publication is final.
Letter to the Editor
Editor, – The recent article by John Holmes about the doctor’s bag (Aust Prescr 2012;35:7-9) recommended that frusemide be relegated to a second- or third-line treatment in patients with acute heart failure. This recommendation is concerning and is counter to international evidence-based guidelines. Both the European Society of Cardiology1 and the American Heart Association/American College of Cardiology guidelines 2 recommend the use of intravenous loop diuretics in acute heart failure. In line with this, the Heart Failure Society of America also recommends intravenous loop diuretics for acute pulmonary oedema.3
On their introduction, loop diuretics revolutionised the management of congestive cardiac failure. Their role remains important today. The recommendation against the use of frusemide as first-line treatment in acute heart failure in appropriately selected patients is potentially dangerous. Non-invasive ventilation strategies and intravenous nitrate therapy do have a role in acute heart failure. Evidence for their efficacy is largely based on studies where they were used with intravenous loop diuretics. The role of these therapies without the concomitant use of loop diuretics has not been established.4–6
In summary, intravenous loop diuretics remain a first-line component in the management of acute heart failure and suggestions to the contrary are not based on sound evidence nor supported by internationally recognised guidelines on the subject.
