Patients transplanted between 1983 and 1998 were classified as early era and those transplanted between 1999 and 2014 were classified as recent era. Group 2 PH was diagnosed in the presence of a mean pulmonary artery pressure (mPAP) &amp;gt; 20 mmHg and pulmonary capillary wedge pressure (PCWP) &amp;gt; 15 mmHg. Isolated post capillary PH (Ipc-PH) was defined as PVR \u2264 2 wood units and combined pre and post capillary PH (Cpc-PH) was defined PVR &amp;gt; 2 wood units. Moderate to severe PH was defined as mPAP \u2265 35 mmHg. The primary outcome was 30-day mortality and long-term mortality according to type and severity of PH. Proportions were analyzed using the chi-square test, and survival analyses were performed using Kaplan-Meier curves and compared using the logrank test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The prevalence of PH in patients transplanted in the early era was 89.1%, whilst 84.2% of patients transplanted in the recent era had PH (<jats:italic>p<\/jats:italic> = 0.3914). There was no difference in the prevalence of a pre-capillary component according to era (<jats:italic>p<\/jats:italic> = 0.4001), but severe PH was more common in the early era (51.1% [early] vs 38.0% [recent] <jats:italic>p<\/jats:italic> = 0.0151). Thirty-day and long-term\u2006 mortality\u2006 were\u2006 not \u2006significantly\u2006 associated\u2006 with severity or type of PH. There was a trend toward increased 30-day mortality in mild PH (10.1%), compared to no PH (4.4%) and moderate to severe PH (6.6%; <jats:italic>p<\/jats:italic> = 0.0653). Long-term mortality did not differ according to the severity of PH (<jats:italic>p<\/jats:italic> = 0.1480). There were no significant differences in 30-day or long-term mortality in IpcPH compared to CpcPH (<jats:italic>p<\/jats:italic> = 0.3974 vs <jats:italic>p<\/jats:italic> = 0.5767, respectively).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Over 30 years, PH has remained very prevalent before CTx.
