Diagnostic and prognostic role of strain pattern according to HF phenotypes.

of GLS		 Prognostic Value
of GLS
HFpEF Subendocardial Longitudinal dysfunction <16%
(minor criteria) [12]		 Predictor of poor prognosis when impaired (HF hospitalization, CV death, cardiac arrest) [8,13,14,15]
HFrEF Transmural Longitudinal and circumferential dysfunction - Predictor of poor prognosis when impaired (all-cause mortality, ventricular arrhythmias) [16,17,18]
Early marker of response to therapy for HF [19]

CV: cardiovascular; GLS: global longitudinal strain; HF: heart failure; HFpEF: heart failure with preserved ejection fraction; HFrEF: heart failure with reduced ejection fraction; LV: left ventricular.
