Pulmonary Hypertension in COVID-19 Associated With Greater Disease Severity, Worse Outcomes

In patients hospitalized for COVID-19, the presence of pulmonary hypertension may be associated with more severe presentation of the disease and worse in-hospital outcomes.

Matched, Mismatched Defects in CTEPH Shown in Preoperative, Postoperative V/Q Scans

Mismatched and matched defects can be observed in preoperative and postoperative ventilation-perfusion scans of patients with chronic thromboembolic pulmonary hypertension.

Pulmonary Hypertension With ILD: Diagnostic and Treatment Challenges

Although pulmonary hypertension as a result of interstitial lung disease is linked to significant morbidity and mortality, there is no consensus regarding screening or management of the disease.

Pulmonary Artery Distensibility Effective Diagnostic Tool for Pulmonary Hypertension Related to Left Heart Disease

Measurements of pulmonary artery distensibility were more effective to detect pulmonary hypertension due to left heart disease than measurements of PA dilatation, in patients with severe heart failure with reduced ejection fraction, aortic stenosis, or primary mitral regurgitation.

Age-related Differences in Hemodynamics and Functional Status in Pulmonary Arterial Hypertension

Older patients with pulmonary arterial hypertension may have lower pulmonary artery compliance and worse right ventricular performance compared with their younger counterparts.

Risk Stratification for Survival in PAH With vs Without Comorbidities

Risk stratification for survival and time to clinical worsening in pulmonary arterial hypertension based on 2015 ESC/ERS guidelines was confirmed only in patients without comorbidities.

Left Heart Disease May Be Associated With Pulmonary Hypertension in Elderly Patients

Left heart disease may be associated with pulmonary hypertension determined by echocardiography.

Bayesian Network Based Machine Learning Improves Risk Stratification in PAH

Bayesian machine learning algorithms can improve discrimination of risk stratification in pulmonary arterial hypertension.

Right Heart Strain Parameters May Be Associated With mPAP and PCWP in PH

Significant associations were detected between right heart strain parameters and mean pulmonary arterial pressure and pulmonary capillary wedge pressure in patients with pulmonary hypertension.

Clinicopathologic Case Series: Pulmonary Arterial Thrombosis in COVID-19

Patients who died from COVID-19 presented mainly with pulmonary disease involving diffuse alveolar damage that led to acute respiratory insufficiency.
