Pericardiocentesis (PC) in patients with pulmonary hypertension (PH) and pericardial effusions has unclear benefits because it has been associated with acute hemodynamic collapse and increased mortality. Data on in-hospital outcomes in this population are limited. The National Inpatient Sample database was used to identify adult patients who underwent PC during hospitalizations between 2016 and 2020. Data were stratified by the presence or absence of PH. A multivariate regression model and case-control matching was used to estimate the association of PH with PC in-hospital outcomes. A total of 95,665 adults with a procedure diagnosis of PC were included, of whom 7,770 had PH. Patients with PH tended to be older (aged 67 ± 15.7 years) and female (56%) and less frequently presented with tamponade (44.9% vs 52.4%). Patients with PH had significantly higher rates of chronic kidney disease, coronary artery disease, heart failure, and chronic lung disease, among other co-morbidities. In the multivariate analysis, PC in PH was associated with higher all-cause mortality (adjusted odds ratio [aOR] 1.40, confidence interval [CI] 1.30 to 1.51) and higher rates of postprocedure shock (aOR 1.53, CI 1.30 to 1.81) than patients without PH. Mortality was higher in those with pulmonary arterial hypertension than other nonpulmonary arterial hypertension PH groups (aOR 2.35, 95% CI 1.46 to 3.80, p <0.001). The rates of cardiogenic shock (aOR 1.49, 95% CI 1.38 to 1.61), acute respiratory failure (aOR 1.56, 95% CI 1.48 to 1.64), and mechanical circulatory support use (aOR 1.86, 95% CI 1.63 to 2.12) were also higher in patients with PH. There was no significant volume-outcome relation between hospitals with a high per-annum pericardiocentesis volume compared with low-volume hospitals in these patients. In conclusion, PC is associated with increased in-hospital mortality and higher rates of cardiovascular complications in patients with PH, regardless of the World Health Organization PH group.
