Hypothesis
Can historical hospital data be used to estimate the prevalence of myocardial infarction in Ontario?
Conclusion
Using historical hospital data, we can reliably estimate the prevalence of myocardial infarction in Ontario.
Supporting Evidence
- The estimated prevalence of myocardial infarction was 2.03%.
- The study created a registry of 346,915 individuals with a history of myocardial infarction.
- There was poor agreement between self-reported heart attacks and hospital admissions.
Takeaway
This study shows that we can figure out how many people had a heart attack by looking at hospital records from many years.
Methodology
The study used hospital admission data from 1988 to 2004 and various statistical models to estimate prevalence.
Potential Biases
Self-reported data may underestimate the prevalence of myocardial infarction.
Limitations
The study may not capture all individuals who had a myocardial infarction, especially those who were not hospitalized.
Participant Demographics
The study included Ontario residents aged 20 and older, with a mean age of 67.4 for men and 74.0 for women.
