Baseline demographic characteristic of hemodialysis patients with left ventricular global peak systolic longitudinal strain (GLS)≤−15% or GLS>−15%.

Abbreviations: BMI, body mass index; CAD, coronary artery disease; DBP, diastolic blood pressure; EDVi, end-diastolic volume index; EF, ejection fraction; E/e′, early transmitral velocity to tissue Doppler mitral annular early diastolic velocity ratio; GLS, global left ventricular peak systolic longitudinal strain; IDWG, inter-dialytic weight gain; IVCe, end-expiratory inferior vena cava diameter; Kt/V, dialysis clearance; LAVi, left atrial volume index; LSRs, systolic longitudinal strain rate; LV, left ventricular; PICP procollagen type I C-terminal peptide; SBP, systolic blood pressure; s′, peak systolic mitral annular velocity. Data are expressed as mean ± standard deviation or number (%). ★P values were calculated by nonparametric Mann-Whitney U test.
