P‐value is referring to differences between dogs with and without PH. No PH, no pulmonary hypertension, ACVIM stage, class of heart failure according to ACVIM classification; LA/Ao, left‐atrial to aortic root ratio; LVEDDn, normalized left‐ventricle end‐diastolic diameter indexed; LVESDn, normalized left‐ventricle end‐systolic diameter indexed; E peak, peak velocity of E wave of transmitral flow; TRPG, tricuspid regurgitation pressure gradient; RV, right ventricle.
