Why the study?
Detecting CAD severity using exercise treadmill test surrogates is important for guiding management, and the authors sought to identify the best surrogates to detect CAD extent and subsequent MACE.
Do specific exercise treadmill test surrogates correlate with the extent of coronary artery disease and future major adverse cardiovascular events in patients with positive ETT results?
Population
48 patients with positive ETT results for coronary ischemia who underwent invasive coronary angiography
Comparison
Patients classified into low-risk, intermediate-risk, and high-risk groups by SYNTAX score
Design
Retrospective study

May support noninvasive CAD risk stratification on positive ETT; hypothesis-generating and requires prospective validation before clinical use.
Do specific exercise treadmill test surrogates correlate with the extent of coronary artery disease and future major adverse cardiovascular events in patients with positive ETT results?
Specific exercise treadmill test parameters, including Duke treadmill score and rate-pressure product, correlate well with the angiographic severity of coronary artery disease and future cardiovascular events.
