Validation of Self-Reported History of Acute Myocardial Infarction
Why the study?
How accurate is self-reported history of acute myocardial infarction among patients admitted with suspected acute myocardial infarction?
Population
3,703 patients admitted to a coronary care unit with suspicion of acute myocardial infarction
Comparison
Self-reported history of previous acute… vs Substantiated history (clinical validation)
Design
Cross-sectional

Implication
Self-reported prior MI warrants record verification in acute settings; leaves open its reliability for unverified morbidity tracking in observational research.
Key Points
- To determine the accuracy and validity of patient self-reported history of previous acute myocardial infarction among individuals presenting with suspected acute cardiac events.
- Evaluated 3,703 patients admitted to a coronary care unit with suspicion of acute myocardial infarction.
- Verified self-reported prior acute myocardial infarction events against medical records to confirm previous diagnoses and identify false positives.
- Substantiated a documented prior acute myocardial infarction in 60% of patients who reported a history of the condition (629 of 1,053).
- Identified a 40% false-positive rate among self-reports, with 40% of false-positive histories attributed to past hospitalizations for unstable angina.

Population

I
Intervention
Self-reported history of previous acute myocardial infarction
C
Comparator
Substantiated history (clinical validation)
O
Outcome
Validity of self-reported history of previous acute myocardial infarction
Self-reported history of prior myocardial infarction has a high false-positive rate (40%) and should be verified with medical records when assessing morbidity trends.
