Cost-effectiveness of Routine Coronary Angiography After Acute Myocardial Infarction
Why the study?
Does routine coronary angiography improve cost-effectiveness compared to initial medical therapy in patients after acute myocardial infarction?
Population
Subgroups of patients after acute myocardial infarction (AMI)
Comparison
Routine coronary angiography and treatment… vs Initial medical therapy without angiography

Implication
Supports selective post-AMI angiography in high-risk subgroups; leaves open routine strategy cost-effectiveness.
Structured PICO
Does routine coronary angiography improve cost-effectiveness compared to initial medical therapy in patients after acute myocardial infarction?
P
Population
Subgroups of patients after acute myocardial infarction (AMI)
I
Intervention
Routine coronary angiography and treatment guided by its results
C
Comparator
Initial medical therapy without angiography
O
Outcome
Incremental cost-effectiveness ratio (cost per quality-adjusted year of life gained)
Routine coronary angiography after AMI is highly cost-effective (<$50,000/QALY) in specific high-risk subgroups such as those with severe postinfarction angina, strongly positive ETT, or prior AMI.
