Illustration for ABI/PWV waveforms and global longitudinal systolic function by deformation measure. (A) One patient with normal ABI value (1.01) yet without clinical HF diagnosis (as Non-PAD/Non-HFpEF) with relatively preserved longitudinal systolic strain (right, from 4-chamber view); (B) another patient in this study with normal ABI value (1.14) with prior HFpEF diagnosis (as Non-PAD/HFpEF), with normal arterial tracing waveforms from lower extremities (left, blue arrows) and globally diminished longitudinal systolic strain pattern (right, from 4-chamber view). ECG, peripheral artery disease; HEpEF, heart failure with preserved ejection fraction; GLS, global longitudinal strain; LVEF, left ventricular ejection fraction.
