May support GLS for HF prognostication beyond LVEF; hypothesis-generating and requires prospective validation before practice change.
Does longitudinal global strain by speckle tracking predict major adverse cardiac events better than LVEF in symptomatic heart failure patients?
Longitudinal global strain by speckle tracking is an independent predictor of major adverse cardiac events in heart failure patients, offering superior prognostic value compared to LVEF.
