Key result
T-wave normalization during stress testing had low sensitivity, identifying only 12.2% of patients with reversible perfusion defects, while 76.4% of patients with normalization had no reversible defect.
Why the study?
Does T-wave normalization during stress testing identify reversible myocardial ischemia in patients with abnormal baseline T-waves?
Observational (n=1,173)
Does T-wave normalization during stress testing identify reversible myocardial ischemia in patients with abnormal baseline T-waves?
T-wave normalization during stress testing is not a reliable indicator of reversible myocardial ischemia in patients with baseline abnormal T-waves.
No takes yet. Share an insight, caveat, or question.
T-wave normalization should not guide ischemia assessment in patients with baseline abnormalities; leaves open its incremental value in prospective cohorts.
Loeb et al. (2007) conducted an observational in Abnormal T-waves on baseline electrocardiograms (n=1,173). T-wave normalization during stress testing vs. No T-wave normalization was evaluated on Reversible perfusion defects. T-wave normalization during stress testing had low sensitivity, identifying only 12.2% of patients with reversible perfusion defects, while 76.4% of patients with normalization had no reversible defect.
