Overview

Scintigraphy may aid post-MI risk stratification over exercise testing; leaves open need for prospective validation in cohorts.

Structured PICO

Does predischarge quantitative exercise thallium-201 scintigraphy better predict cardiac events compared to submaximal exercise treadmill testing and coronary angiography in patients with uncomplicated acute myocardial infarction?

P
Population
140 consecutive patients with uncomplicated acute myocardial infarction
I
Intervention
Predischarge quantitative exercise thallium-201 (201Tl) scintigraphy
C
Comparator
Submaximal exercise treadmill testing and coronary angiography
O
Outcome
Cardiac events (composite of death, recurrent myocardial infarction, or severe class III or IV angina pectoris)composite

Predischarge exercise thallium-201 scintigraphy is a more sensitive predictor of subsequent cardiac events than ST segment depression, angina, or extent of angiographic disease after uncomplicated acute myocardial infarction.
