    BackgroundSepsis and pulmonary arterial hypertension (PAH) may both present in a single patient in the intensive care unit. The impact of PAH on the sepsis process is not well understood. Here we assess the effect of PAH in patients with sepsis from multiple perspectives.MethodsPatients with sepsis with or without PAH underwent propensity score matching according to age, sex and ethnicity. Clinical complications, hemodynamics, and laboratory examinations, including heart injury and inflammation, were compared between the 2 groups. We aimed to model the relationship between the severity of PAH and systemic inflammation levels using linear regression analysis. Factors associated with 28-day and one-year mortality in patients with sepsis with PAH were also analyzed using binary logistic regression.ResultsA total of 285 pairs of patients with sepsis with or without PAH were included in the analysis. There were no significant differences in the C-reactive protein (CRP), white blood cell (WBC), or lactate levels or neutrophil percentage between the 2 groups, and the mean pulmonary arterial pressure and N-terminal pro b-type natriuretic peptide (NTproBNP) level did not correlate with CRP, WBC or lactate. The cardiac injury indexes were significantly higher in the PAH group. Lower mean arterial pressure was found in patients with PAH. Longer ventilation duration was a risk factor for, while obesity was protective against, both short- and long-term mortality in patients with sepsis with PAH.ConclusionsPAH had little effect on the inflammation profile in sepsis, but it may worsen the sepsis outcome by impairing cardiac function and subsequent hemodynamic stability.Copyright © 2022 Southern Society for Clinical Investigation.
