Limitations of Continuous Ambulatory Electrocardiogram Monitoring for Detecting Coronary Artery Disease
Why the study?
Does continuous ambulatory ECG monitoring accurately detect coronary artery disease in symptomatic patients with chest pain and normal resting ECGs?
Population
70 symptomatic patients with chest pain and normal resting ECGs
Comparison
Calibrated continuous ambulatory… vs Graded treadmill exercise

Implication
Supports limited diagnostic value of ambulatory monitoring versus treadmill testing; leaves open its role in selected subgroups pending prospective validation.
Structured PICO
Does continuous ambulatory ECG monitoring accurately detect coronary artery disease in symptomatic patients with chest pain and normal resting ECGs?
P
Population
70 symptomatic patients with chest pain and normal resting ECGs
I
Intervention
Calibrated continuous ambulatory electrocardiogram (ECG) monitoring
C
Comparator
Graded treadmill exercise (with selective coronary cineangiography as the reference standard)
O
Outcome
Detection of coronary artery disease (sensitivity and specificity)surrogate
Continuous ambulatory ECG monitoring is of limited value for detecting or excluding coronary artery disease in symptomatic patients with normal resting ECGs.
