Abstract The modern era in cardiopulmonary medicine began in the 1940s, when Cournand and Richards pioneered right-heart catheterization. Until that time, no direct measurement of central vascular pressure had been performed in humans.

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

Pulmonary hypertension is said to occur when the mean pulmonary arterial pressure exceeds 25 mmHg at rest or 30 mmHg during exercise. There are many causes but the term Pulmonary arterial hypertension (PAH) is used to describe a rare group of illnesses that share histopathological similarities in the small muscularised pulmonary arterioles leading to ...

Oxygenated hemoglobin (OxyHem) in arterial blood may reflect disease severity in patients with systemic sclerosis (SSc). The aim of this study was to analyze the predictive value of OxyHem in SSc patients screened for pulmonary hypertension (PH). OxyHem (

Therapeutic efficacy of TBC3711 in monocrotaline-induced pulmonary hypertension [PDF]
Background: Endothelin-1 signalling plays an important role in pathogenesis of pulmonary hypertension. Although different endothelin-A receptor antagonists are developed, a novel therapeutic option to cure the disease is still needed.

Two-dimensional transthoracic echocardiography at rest for the diagnosis, screening and management of pulmonary hypertension [PDF]
Doppler echocardiography is widely used in everyday clinical practice for the detection of pulmonary hypertension (PH) in symptomatic patients and in populations particularly at risk of pulmonary arterial hypertension (PAH). It allows accurate estimation

Prognostic impact of hypochromic erythrocytes in patients with pulmonary arterial hypertension
Background Iron deficiency affects up to 50% of patients with pulmonary arterial hypertension (PAH) but iron markers such as ferritin and serum iron are confounded by several non-disease related factors like acute inflammation and diet.

Pulmonary Hypertension Caused by Pulmonary Venous Hypertension [PDF]
The effect of pulmonary venous hypertension (PVH) on the pulmonary circulation is extraordinarily variable, ranging from no impact on pulmonary vascular resistance (PVR) to a marked increase. The reasons for this are unknown. Both acutely reversible pulmonary vasoconstriction and pathological remodeling (especially medial hypertrophy and intimal ...

Pilot study of losartan for pulmonary hypertension in chronic obstructive pulmonary disease. [PDF]
BACKGROUND: Morbidity in COPD results from a combination of factors including hypoxia-induced pulmonary hypertension, in part due to pulmonary vascular remodelling. Animal studies suggest a role of angiotensin II and acute studies in man concur.

Transforming growth factor-beta receptor mutations and pulmonary arterial hypertension in childhood [PDF]
BACKGROUND: Pulmonary arterial hypertension (PAH) is a potentially fatal vasculopathy that can develop at any age. Adult-onset disease has previously been associated with mutations in BMPR2 and ALK-1.
