The ABC Target-Board Pulmonary Hypertension Management [22]. Right panel: schematic imaginary division of the human body into three rheological spheres (A, B, and C): A = amount of fluid; B = barriers of cells; C = covering tissues; “Somarheology theory” [23]. Middle panel: Dana Point PAH classification [53]. Left panel: mismatching the Dana Point groups of PAH & ABC spheres. Endothelial shear stress could be triggered at B, through A and/or C
