Fig. 1. Individual patient values for global longitudinal strain are plotted for patients with normal function, patients with chronic AR and preserved LV ejection fraction (AR + PEF), and patients with chronic AR with reduced LV ejection fraction (AR + REF). There is a clear difference in the individual patient values for normals vs. both groups of AR patients. AR + PEF: chronic aortic regurgitation and preserved LV ejection fraction, AR + REF: chronic aortic regurgitation and reduced LV ejection fraction, LV: left ventricular.
