The role of ambulatory ST-segment monitoring in the diagnosis of coronary artery disease: comparison with exercise testing and thallium scintigraphy
Why the study?
Does ambulatory ST-segment monitoring accurately diagnose coronary artery disease compared to exercise testing and thallium scintigraphy in patients with chest pain?
Population
100 consecutive patients who underwent exercise testing and coronary arteriography for chest pain.
Comparison
48 hours of ambulatory ST-segment monitoring vs Conventional exercise testing and thallium-201…

Implication
Does not support replacing exercise testing; leaves open ambulatory monitoring's diagnostic role pending prospective studies.
Structured PICO
Does ambulatory ST-segment monitoring accurately diagnose coronary artery disease compared to exercise testing and thallium scintigraphy in patients with chest pain?
P
Population
100 consecutive patients who underwent exercise testing and coronary arteriography for chest pain (26 with normal coronary arteries, 74 with significant coronary artery disease).
I
Intervention
48 hours of ambulatory ST-segment monitoring
C
Comparator
Conventional exercise testing and thallium-201 radioisotope imaging
O
Outcome
Detection of underlying coronary artery disease (sensitivity and specificity)surrogate
Ambulatory ST-segment monitoring is as valuable as stress testing for detecting coronary artery disease and can additionally identify patients with coronary spasm.
