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.

Pulmonary vascular resistance and clinical outcomes in patients with pulmonary hypertension: a retrospective cohort study.

The Lancet Respiratory Medicine, 2020
BACKGROUND In pulmonary hypertension subgroups, elevated pulmonary vascular resistance (PVR) of 3·0 Wood units or more is associated with poor prognosis. However, the spectrum of PVR risk in pulmonary hypertension is not known.

Elevated pre‐transplant pulmonary vascular resistance is associated with early post‐transplant atrial fibrillation and mortality

ESC Heart Failure, 2020
Severely elevated pre‐transplant pulmonary vascular resistance (PVR) has been linked to adverse effects after heart transplantation (HTX). The impact of a moderately increased PVR before HTX on post‐transplant outcomes remains uncertain.

Chronic Inhibition of Toll‐Like Receptor 9 Ameliorates Pulmonary Hypertension in Rats

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Recent accumulating evidence suggests that toll‐like receptor 9 (TLR9) is involved in the pathogenesis of cardiovascular diseases. However, its role in pulmonary hypertension remains uncertain.
