Background: Exercise pulmonary hypertension (PH) was defined by a mean pulmonary arterial pressure (mPAP)/cardiac output (CO) slope >3 mmHg·min·L between rest and exercise in the 2022 European Society of Cardiology/European Respiratory Society PH guidelines. However, large, multicentre studies on the prognostic relevance of exercise haemodynamics and its added value to resting haemodynamics are missing.

Patients And Methods: The PEX-NET (Pulmonary Haemodynamics during Exercise Network) registry enrolled patients who underwent clinically indicated right heart catheterisations both at rest and ergometer exercise from 23 PH centres worldwide.

Article Synopsis
  • The study investigates the significance of the tricuspid annular plane systolic excursion (TAPSE) to systolic pulmonary arterial pressure (sPAP) ratio in predicting outcomes for patients suspected of having pulmonary hypertension (PH), particularly those with normal or mildly elevated mean pulmonary arterial pressure (mPAP).
  • Researchers analyzed data from 237 patients with mPAP < 25 mm Hg over an observation period of 63 months, finding that the TAPSE to sPAP ratio was a strong independent predictor of mortality and clinical worsening events.
  • The results also indicated that this ratio correlates with exercise capacity (measured by the 6-minute walk distance) and the hemodynamics related to exercise, emphasizing its potential

Article Synopsis
  • The study aimed to create percentile charts for arterial oxygen saturation (SpO), heart rate (HR), and cerebral oxygen saturation (crSO) in very or extremely preterm neonates during their first 15 minutes after birth.
  • It analyzed data from the COSGOD III trial, focusing on neonates with favorable outcomes, excluding those with early inflammatory issues, and utilized various methods for measuring the oxygen and heart metrics.
  • The findings revealed specific percentiles for SpO, HR, and crSO at 2, 5, 10, and 15 minutes post-birth, providing a new reference that could aid in better managing oxygen levels during the critical stabilization period after delivery.
