Why the study?

Does thallium-201 exercise myocardial scintigraphy improve the detection of multivessel coronary artery disease and residual jeopardized myocardium compared to clinical findings in patients 3 weeks after myocardial infarction?

Population

32 patients evaluated 3 weeks after myocardial infarction

Comparison

Thallium-201 exercise myocardial scintigraphy vs Clinical findings

Design

Cross-sectional

Follow-up

3 weeks post-MI

Implication

May improve post-MI detection of multivessel disease over clinical findings; hypothesis-generating and should not yet change practice.

Structured PICO

Does thallium-201 exercise myocardial scintigraphy improve the detection of multivessel coronary artery disease and residual jeopardized myocardium compared to clinical findings in patients 3 weeks after myocardial infarction?

P
Population
32 patients evaluated 3 weeks after myocardial infarction
I
Intervention
Thallium-201 exercise myocardial scintigraphy (limited multilead submaximal treadmill testing with thallium-201 myocardial scintigraphy at end-exercise and at rest)
C
Comparator
Clinical findings (angina, heart failure, or ventricular arrhythmias during the late convalescent period)
O
Outcome
Detection of multivessel coronary artery disease (MVCAD) and residual jeopardized myocardium (JEP) defined angiographicallysurrogate

Thallium-201 exercise myocardial scintigraphy is a safe and useful noninvasive tool for identifying multivessel coronary artery disease and residual jeopardized myocardium 3 weeks post-MI, outperforming clinical findings.
