Multivariate analysis for mortality within 30 days after HTX

	Hazard ratio	95% confidence interval	P‐value
Native PVR before HTX (≥300 dyn·s·cm−5 ≙ 3.75 WU)	4.4	2.5–7.6	<0.01
Recipient age (>60 years)	1.2	0.6–2.2	0.61
Coronary artery disease (in total)	0.7	0.4–1.2	0.20
Previous open‐heart surgery (in total)	1.8	0.9–3.3	0.08
Donor age (>40 years)	1.1	0.6–1.9	0.76
Ischaemic time (≥240 min)	0.6	0.3–1.2	0.16

dyn, g·cm·s⁻²; HTX, heart transplantation; PVR, pulmonary vascular resistance; WU, Wood unit (≙ 80 dyn·s·cm⁻⁵).
