Implication
Supports selective immediate angiography post-MI with ischemia; confirms no benefit for routine use in stable patients without persistent ischemia.
Structured PICO
Does coronary angiography and angioplasty improve outcomes and justify costs in patients after acute myocardial infarction?
P
Population
Patients after acute myocardial infarction
I
Intervention
Coronary angiography and angioplasty
C
Comparator
Thrombolytic therapy with angioplasty only for specific indications, or conservative management without routine angiography
O
Outcome
Clinical outcomes, procedural risks, utilization rates, and costs
While immediate angiography and angioplasty benefit specific acute MI patients and those with persistent ischemia, routine use in uncomplicated cases lacks evidence and drives substantial healthcare costs.
