Multivariate Cox regression with baseline data to predict all‐cause mortality in patients with PH (PA pressure mean ≥25 mmHg)

Variables	Multivariate
	HR	(95% CI)	P value
Ees/Ea	0.151	(0.037–0.619)	0.003
PA compliance	0.518	(0.335–0.799)	0.003

CI, confidence interval; DPD, diastolic pressure gradient; Ea, effective arterial elastance; Eed, end‐diastolic elastance; Ees, end‐systolic elastance; EF, ejection fraction; HR, hazard ratio; LVESDV, left ventricular end‐diastolic volume; LVESV, left ventricular end‐systolic volume; MR, mitral valve regurgitation; PA, pulmonary artery; PCWP, pulmonary capillary wedge pressure.

Additional baseline univariate variables associated with all‐cause mortality (P < 0.1) entered the multivariate model: PVR, PA compliance, PCWP, mitral regurgitation (Degree 0‐III), tricuspid regurgitation; Eed; Ea and existence of CpcPH. (as categorical and/or continuous variable).

Age, LVEF, Ees, RC time, DPD, Tau, LVEDV, and LVESV did not enter the model because univariate analysis showed P > 0.1.
