Current risk assessment of pulmonary embolism (PE) stratifies patients based on hemodynamic stability, clinical parameters of severity, right ventricular dysfunction and cardiac injury but fails to integrate a wide variety of comorbid conditions. The Charlson Comorbidity Index (CCI) predicts mortality based on patients' diseases and provides a system to quantify disease burden.

The discrimination between pre and postcapillary exercise-induced pulmonary hypertension relies on accurate measurement of pulmonary capillary wedge pressure, which can be unreliable. We found that exercise pulmonary artery compliance and right atrial pressure (AUC 0.88, 0.89, respectively) can differentiate subtypes of exercise-induced pulmonary hypertension in the absence of wedge pressure.

In this Community Call, we discussed:

  • Deep phenotyping of unaffected carriers of pathogenic BMPR2 variants screened for pulmonary arterial hypertension
  • Pulmonary hypertension induced by right pulmonary artery occlusion: hemodynamic consequences of Bmpr2 mutation

The objective of this analysis was to compare clinician-based and formally calculated risk assessments by REVEAL Lite 2 and COMPERA 2.0 and to characterize parenteral prostacyclin utilization within 90 days of baseline in high-risk patients. A multisite, double-blind, retrospective chart review of patients with pulmonary arterial hypertension (PAH) was conducted with an index period of January 2014–March 2017.

Therapeutic exercise has not been widely adopted in pediatric pulmonary hypertension (PH), despite adult data supporting its safety and efficacy. While physical limitations may prevent children with PH from participating in physical activity, other barriers to and facilitators of physical activity are unknown.
