The impact of gas transfer on responses to exercise training in patients with pulmonary hypertension

Pulmonary arterial hypertension (PAH) is a progressive disease with significant morbidity and mortality. Due to nonspecific symptoms, diagnosis can be challenging and subject to substantial delays. Using data from Mayo Clinic′s electronic health records, we looked at causes of delayed diagnosis and whether earlier diagnosis means better outcomes.

We read with great interest the recent article on patient-specific hemodynamic modeling to estimate microvascular disease burden and predict response to pulmonary endarterectomy (PEA) in chronic thromboembolic pulmonary hypertension (CTEPH) [1]. The integration of multiscale structure-based modeling with routine clinical data addresses the key challenges of quantifying distal microvascular remodeling and anticipating heterogeneous hemodynamic responses after technically successful PEA.

Assessing operability in late-presenting ventricular septal defects (VSD) with pulmonary arterial hypertension (PAH) is complex. Although a comprehensive assessment is often recommended, pulmonary vascular resistance index (PVRI) is the cornerstone of most decisions

Pulmonary artery wedge pressure is a crucial measurement for differentiating between hemodynamic categories of pulmonary hypertension (PH), particularly Groups 1 and 2. In this prospective study, we analyzed the diagnostic utility of checking wedge oxygen saturation to confirm wedge position during right heart catheterization in patients referred for PH.
