Key result
T-wave normalization with exercise was associated with no transient myocardial perfusion defect in 80% of studies, indicating poor positive predictive value for diagnosing myocardial ischemia.
Why the study?
Does T-wave normalization with exercise predict transient myocardial perfusion defects (ischemia) in patients with resting T-wave inversion?
Observational (n=82)
Does T-wave normalization with exercise predict transient myocardial perfusion defects (ischemia) in patients with resting T-wave inversion?
T-wave normalization with exercise is a nonspecific finding that has poor positive predictive value for diagnosing transient myocardial ischemia.
No takes yet. Share an insight, caveat, or question.
T-wave normalization with exercise warrants caution in diagnosing ischemia; leaves open its prognostic role pending prospective studies.
Wagoner et al. (2017) conducted an observational in T-wave inversion on resting ECG with normalization during exercise (n=82). T-wave normalization with exercise vs. Patients undergoing exercise thallium testing for suspected coronary artery disease was evaluated on No transient myocardial perfusion defect. T-wave normalization with exercise was associated with no transient myocardial perfusion defect in 80% of studies, indicating poor positive predictive value for diagnosing myocardial ischemia.
