Here’s a case I had recently:
62 year old male presents to the Emergency Department with what he calls a flare-up of his congestive cardiac failure. He states he is short of breath. He is a frequent presenter to the department with this complaint. He has not taken his frusemide for the past 48hours.
He states that he feels very tired.

I am going to discharge him, however it is late at night and he lives alone, so we decide to keep him in the department overnight.
In the morning, he looks well and feels better, but still lethargic, ECG is unchanged, but for some reason someone does a follow-up troponin and it is 4.
He is diagnosed with a NSTEMI and sent to cardiology.

Pope et al(NEJM 2000;343:1167-1170) looked at the rate of missed diagnoses of cardiac ischaemia in the emergency department.
This was a study of some 10689 patients and the conclusion was that there was a subgroup of patients more likely not to be admitted, who had ischaemia or infarction.
Those more likely to not be admitted were: […]Read More
