Complementary Value of Two-Dimensional Exercise Echocardiography to Routine Treadmill Exercise Testing
Why the study?
Does two-dimensional exercise echocardiography improve the detection of coronary disease compared to routine treadmill exercise testing in patients undergoing coronary arteriography?
Population
95 patients who subsequently had coronary arteriography
Comparison
Two-dimensional exercise echocardiography vs Routine treadmill exercise testing
Design
Cross-sectional

Implication
Exercise echocardiography may detect more ischemia than ECG in coronary disease without prior MI; leaves open need for prospective validation before wider use.
Structured PICO
Does two-dimensional exercise echocardiography improve the detection of coronary disease compared to routine treadmill exercise testing in patients undergoing coronary arteriography?
P
Population
95 patients who subsequently had coronary arteriography (36 with prior myocardial infarction, 59 without prior infarction)
I
Intervention
Two-dimensional exercise echocardiography (done during rest and after exercise)
C
Comparator
Routine treadmill exercise testing (exercise electrocardiogram)
O
Outcome
Detection of coronary disease (abnormal vs normal response) compared to coronary arteriographysurrogate
Exercise echocardiography provides complementary diagnostic value to routine treadmill testing, particularly when treadmill results are nondiagnostic or a false-negative is suspected.
