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.
Mismatched and matched defects can be observed in preoperative and postoperative ventilation-perfusion scans of patients with chronic thromboembolic pulmonary hypertension.
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.
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.
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 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 determined by echocardiography.
Bayesian machine learning algorithms can improve discrimination of risk stratification in pulmonary arterial hypertension.
Significant associations were detected between right heart strain parameters and mean pulmonary arterial pressure and pulmonary capillary wedge pressure in patients with pulmonary hypertension.
Patients who died from COVID-19 presented mainly with pulmonary disease involving diffuse alveolar damage that led to acute respiratory insufficiency.
