Implication
May inform decisions in selected octogenarians with AMI; hypothesis-generating and requires RCT confirmation before practice change.
Structured PICO
Does coronary revascularization improve survival and functional status in patients aged 80 years and older with acute myocardial infarction?
P
Population
93 patients aged 80 years and older hospitalized with an acute myocardial infarction who underwent cardiac catheterization before discharge and were eligible for revascularization.
I
Intervention
Coronary revascularization (angioplasty [n=41] or coronary artery bypass surgery [n=18])
C
Comparator
Medical therapy without revascularization [n=34]
O
Outcome
Survival, quality of life, and functional status at least 1 year after dischargehard clinical
In very elderly patients (≥80 years) with acute myocardial infarction, coronary revascularization is associated with improved 1-year survival and functional status compared to medical therapy alone.
Limitations
- Study design did not permit definite conclusions (retrospective observational design)
