Evaluation of arrhythmias in the late hospital phase of acute myocardial infarction compared to coronary care unit ectopy.
Why the study?
Does continuous portable monitoring during the late hospital phase detect arrhythmias missed by initial coronary care unit monitoring in survivors of acute myocardial infarction?
Population
83 consecutive survivors of acute myocardial infarction
Comparison
Continuous 8-hour portable monitoring during the… vs Coronary care unit monitoring
Design
Cohort
Follow-up
3 weeks (entire hospital stay)

Implication
Early MI arrhythmia absence does not preclude late events; leaves open whether extended monitoring improves outcomes.
Structured PICO
Does continuous portable monitoring during the late hospital phase detect arrhythmias missed by initial coronary care unit monitoring in survivors of acute myocardial infarction?
P
Population
83 consecutive survivors of acute myocardial infarction
I
Intervention
Continuous 8-hour portable monitoring during the ambulatory phase (second and third weeks in hospital)
C
Comparator
Coronary care unit monitoring (initial 3 to 5 days)
O
Outcome
Prevalence and nature of arrhythmiassurrogate
Continuous monitoring reveals that complicated ventricular arrhythmias frequently occur in the late hospital phase of acute myocardial infarction even if absent during initial CCU monitoring.
