ABSTRACT: Objective: To identify electrocardiographic parameters that predict extent of
early improvement in ejection fraction (EF) in patients with stress
cardiomyopathy. Methods: We
collected baseline clinical, ECG and imaging data and follow up
echocardiography data on 30 consecutive patients with stress cardiomyopathy.
The relationship between baseline ECG parameters and Delta EF was evaluated by
univariate and multivariable analysis. Results: Median EF improved from 35% to 55% (p Conclusion: The number of leads with T wave
inversion is negatively correlated with and is an independent predictor of the
extent of early improvement of EF in patients with stress cardiomyopathy. Hence
the ECG at initial presentation can be used as a simple tool to predict LV
function recovery.
