Acute heart failure is extremely common amongst patients presenting to our ED’s. No doubt you’ll have several patients each day presenting who need assessment and treatment for this condition. Understanding some of the underlying physiology and evidence base surrounding the condition can greatly improve the treatment you can give to your patients.

In this podcast we’ll run through just that. Below are a list of some of the references and resources we’ll cover.

We’d love to hear any comments or feedback you have for us.

    hi

    great article as always. for some reason though i can never get the podcast to play. any ideas why? i use firefox.

  2. sl says:

    Thanks!

    Afraid not ideas other than browsers or blocked pop-ups?

    Try through the iTunes feed otherwise https://itunes.apple.com/gb/podcast/heft-emcast/id751375884?mt=2

    Hope you get it sorted!

    Great podcast, well done.

    As for failed podcast of poster above…had to go to 3rd browser for playing podcast. chrome -> safari -> firefox worked. On Mac.

    still worth it. but may want to have your giant IT department take a look.

    cheers,
    steve

    Hi Steve,

    We’ve changed the mp3 plug in on the site. Let me know if this solves the problem?

    Cheers

    With regards to diuretic doses – the paper cited (Hasselblad et al) merely states that higher doses of furosemide are associated with increased mortality. There is no causative link established. Indeed, the paper itself states “… higher diuretic use could have been a marker of a sicker patient at high risk of mortality regardless of diuretic therapy.”

    “Prospective, carefully controlled studies will be required to clarify whether there is a causal relationship between diuretic use and adverse outcomes, or alternatively if diuretic dosage is just a surrogate for disease severity.” http://circheartfailure.ahajournals.org/content/2/1/56.full

    The DOSE study which suggested that infusions and boluses of diuretics have similar efficacy was looking at symptom relief as an endpoint rather than mortality. It suggested that higher doses of diuretics (2.5x the patient’s previous oral dose, but given intravenously as a high dose, or 1x the oral dose given intravenously as a low dose) have more efficacy in symptom control at the expense of an increase in renal impairment.

    Concluding in favour of high dose nitrates with conservative use of diuretics based on the results of two studies of 110 and 40 people seems a little strange as it is going against the vast majority of evidence and accepted practice, especially when one paper looks at 24 hour outcomes!

    Hello unnamed

    Thanks for the reply, always great to get some feedback/comments

    I agree with a lot of your points and it’s important to emphasise that we’re talking about those sick patients with pulmonary oedema who are critically unwell. Our main points were;

    – Nitrates – safe, good physiological rationale and work immediately.

    – Furosemide- it’s what these patients get and that’s probably OK but it’s not the magic drug some may think it is. There is not a strong evidence base to confirm a strong mortality benefit in this specific critically unwell cohort. It is important to understand the renal side effects that can occur and whilst symptom control is important longer term hard outcomes are probably more important.

    So again thanks for the comments, we’re not trying to say the answer is black and white, actually far from it but the evidence doesn’t give the magic bullet yet.

    Simon
