Tetrahydrobiopterin analogues with NO-dependent pulmonary vasodilator properties [PDF]

, 2011
Reduced NO levels due to the deficiency of tetrahydrobiopterin (BH4) contribute to impaired vasodilation in pulmonary hypertension Due to the chemically unstable nature of BH4 it was hypothesised that oxidatively stable analogues of BR, would be able to ...

Improving guidance for the correctability of congenital cardiovascular shunts with increased pulmonary vascular resistance

International Journal of Cardiology Congenital Heart Disease, 2021
Background: Based upon expert opinion, guidelines have been proposed for the correctability of congenital cardiovascular shunts with increased pulmonary vascular resistance. This study reports the accuracy of published guidelines using a dataset from the

Clinical application of pulmonary vascular resistance in patients with pulmonary arterial hypertension

Journal of Cardiothoracic Surgery, 2021
Pulmonary arterial hypertension is a type of malignant pulmonary vascular disease, which is mainly caused by the increase of pulmonary vascular resistance due to the pathological changes of the pulmonary arteriole itself, which eventually leads to right ...

Cinaciguat (BAY-582667) Modifies Cardiopulmonary and Systemic Circulation in Chronically Hypoxic and Pulmonary Hypertensive Neonatal Lambs in the Alto Andino

Frontiers in Physiology, 2022
Neonatal pulmonary hypertension (NPHT) is produced by sustained pulmonary vasoconstriction and increased vascular remodeling. Soluble guanylyl cyclase (sGC) participates in signaling pathways that induce vascular vasodilation and reduce vascular ...

Prediction of Operability by Pulmonary Artery Acceleration Time and Right Ventricular Ejection Time in Large Ventricular Septal Defects with Severe Pulmonary Arterial Hypertension

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2023
Background: Diagnosing and treating cardiopulmonary illnesses in children depend heavily on evaluating pulmonary hemodynamics. Severe pulmonary artery hypertension (PAH) and Eisenmenger's syndrome are most frequently seen in post-tricuspid shunts.
