Abbreviations: Blood pressure (BP), meridional end-systolic wall stress (ESS), circumferential end-systolic wall stress (cESS), left ventricular inner diameter in systole (LVIDs), posterior wall thickness in systole (PWTs), and septal wall thickness in systole (IVSs). Please observe that values for cardiac size are reported in absolute values.
