Recently we published part one of our series on cardiac troponins. If you haven't checked it out yet, you can find it here. In the second part, we're going to take a look at high sensitivity troponins and some of the more advanced areas around understanding cardiac troponin and its use in practice. We'll give you a quick run down on the troponin lingo - the language you need to be able to speak in order to fully understand how to use high sensitivity troponin in your practice, including terms like the limit of blank, limit of detection, co-efficient of variation and 99th percentile.
We'll also ask whether Joe Lex had a point when he stirred up controversy around these assays with this legendary tweet:
What if we called it "low specificity troponin" instead of "high sensitivity troponin?" Would that knock some sense into people?

So, check out the associated BLOG POST here and listen to the podcast. There is more on diagnostics and troponin to come very soon.
Hope you enjoy! Please keep the feedback, questions and comments coming. As always, we'd love to hear from you.

DOI: Much of my research work involves HsT. To help with this I have received reagents from companies who make HsT assays, but I not received any other financial benefit or gifts in kind as part of my work and have no financial ties to any companies.

Breathless patients are a challenge in the ED. Shortness of breath can be a frightening presenting complaint for both patients and doctors. As always, think about the possible life threatening causes and actively rule them out. For breathless patients think especially about:
In this podcast Iain and Simon discuss their approach to breathless patients in the ED which we hope will provide you with a good starting point.
For those of you who are more visual learners here is the video recorded a few years ago for SEMEP featuring our very own Iain Beardsell.

Oxygen - or no oxygen??
Oxygen administration is rarely a problem in the immediate and acute
setting - and can save lives. So yes, when you first approach a patient
who is short of breath, get that oxygen on while you make your
assessment then think about the finer points of respiratory failure
afterwards.
Where do I begin?
A focused history, including asking the patient about previous conditions and whether they know what's going on!
And then - initial assessment and examination including vital signs
(especially respiratory rate), looking for clues as to the underlying
cause of their breathlessness, remembering the five common causes.
What treatments might be useful?
A small fluid bolus might help and carries relatively little risk;
think about the need for nebulised bronchodilators for patients with
asthma or COPD, and remember that antibiotics given early to patients
with sepsis save lives.
If the patient has pain we should definitely treat that too.
Which investigations might help me find out more?
One of the key investigations in patients with shortness of breath is the humble chest radiograph. There are some phenomenal FOAM resources for interpretation of CXRs (along with other XRs) at Radiology Masterclass. Well worth bookmarking for your ED shifts (but do ask a senior if you're unsure).

Think! Do you really need an ABG? If the answer is yes, please use local anaesthetic! Your patients will thank you...

We've all had headaches, but not often severe enough to prompt us to seek help in an Emergency Department.
In our practice 10% of patients who do present to the ED with a primary presentation of headache will have serious pathology and our job as Emergency Physicians is to work out who these are. Key to this is actively ruling out the life-threatening and life-changing diagnoses:
