- Results are reported as mean ± standard deviation. Abbreviations: Vmax; maximal volume; LAEF, left atrial total ejection fraction; LAPEF, left atrial passive ejection fraction; LAAEF, left atrial active ejection fraction; Smax, maximal global strain (a longitudinal strain vs. b circumferential strain); r, Pearson's correlation.
