Correlation between TAPSE and PASP, relationships of TAPSE/PASP ratio with TAPSE, RVOT-FS, LVEF, and MAPSE. a. Correlation between the TAPSE and PASP. TAPSE was not associated with PASP, r = 0.113, p = 0.224. b. Relationship of TAPSE/PASP ratio with TAPSE tertiles (low: TAPSE ≤15.0 mm; middle: TAPSE 15.1 mm–19.9 mm; high: TAPSE ≥20.0 mm). c. Relationship of TAPSE/PASP ratio with RVOT-FS tertiles (low: RVOT-FS ≤ 34%; middle: RVOT-FS 35–47%; high: RVOT-FS ≥ 48%). d. Relationship of TAPSE/PASP ratio with LVEF tertiles (low: LVEF ≤50%; middle: LVEF 51–62%; high: LVEF ≥63%). e. Relationship of TAPSE/PASP ratio with MAPSE tertiles (low: MAPSE ≤11.0 mm; middle: MAPSE 11.1 mm–14.0 mm; high: MAPSE ≥14.1 mm). Lines in b-e indicate median and interquartile range, * p < 0.05, ** p < 0.01, *** p < 0.001(Kruskal-Wallis test). TAPSE: tricuspid annular plane systolic excursion; PASP: pulmonary arterial systolic pressure; RVOT-FS: right ventricular outflow tract fractional shortening; LVEF: left ventricular ejection fraction; MAPSE: mitral annular plane systolic excursion
