Hypothesis
Non-availability of cardiac catheterization facilities might translate into a higher use of non-invasive cardiac procedures.
Conclusion
On-site availability of cardiac catheterization facilities is associated with greater use of invasive procedures, but does not affect fatal and non-fatal outcomes after acute myocardial infarction.
Supporting Evidence
- Patients at hospitals with catheterization had higher rates of invasive procedures.
- Mortality rates were similar regardless of catheterization availability.
- Non-invasive tests were not used more at hospitals without catheterization.
Takeaway
Hospitals with catheterization labs do more heart procedures, but not having one doesn't mean patients do worse overall.
Methodology
Patients admitted with a first AMI were identified using administrative databases, and outcomes were compared between hospitals with and without catheterization facilities.
Potential Biases
Potential misclassification bias in readmission diagnoses.
Limitations
The study could not account for in-hospital pharmacological treatments and detailed clinical characteristics.
Participant Demographics
Patients were primarily elderly, with similar demographics across both hospital types.
Statistical Information
Confidence Interval
95% CI for various outcomes reported.
