Key result
Initial acute MI diagnosis by junior doctors shows only ~55% sensitivity vs strict criteria.
Why the study?
Prompt diagnosis of acute myocardial infarction is critical for thrombolysis eligibility, but initial working diagnoses may be inaccurate, affecting treatment decisions.
Population
All patients admitted with suspected acute MI in Nottingham from 1982 to 1986 and 1989
Comparison
Initial working diagnosis vs final diagnosis based on cardiac enzymes and ECG
Design
Observational study using registry data

Low sensitivity of junior doctors' initial MI diagnosis may miss eligible patients for thrombolysis; leaves open whether targeted training improves diagnostic accuracy.
Observational
Yes
Gray et al. (1993) conducted an observational in Suspected acute myocardial infarction. Initial working diagnosis of acute MI vs. Final diagnosis using cardiac enzymes and ECG was evaluated on Sensitivity and specificity of the initial working diagnosis. An initial admission diagnosis of acute myocardial infarction by junior doctors carried a sensitivity of 55% and specificity of 88% compared to strictly defined criteria.
