RV contractility and exercise-induced pulmonary hypertension in chronic mountain sickness : a stress echocardiographic and tissue doppler imaging study
(ELSEVIER, 2013-12)
Objectives.
The aim of this study was to evaluate right ventricular (RV) and left ventricular function
and pulmonary circulation in chronic mountain sickness (CMS) patients with rest and stress echocardiography compared ...
Excessive polycythemia occurs in young high-altitude (3600 M) residents in the absence of lung disease
(High Altitude Medicine & Biology, 2002-04-18)
Objective: Chronic Mountain Sickness occurs in , 8% of the La Paz
population. We asked whether its primary diagnostic sign, excessive polycythemia (EP), occurred in youngeraged persons
without lung disease. Methods: ...
Protective effect of female sex hormones against pulmonary hypertension in Bolivian high altitude natives
(High Altitude Medicine & Biology, 2003-02-19)
There is abundant evidence that female sex hormones have protective effects in the systemic circulation in both animals and humans,
but little is known regarding their role in the regulation of the pulmonary circulation. ...
Chronic mountain sickness and cor pulmonale La Paz-Bolivia (3,600-4,100 m)
(Life on the Qinghai Tibetan plateau, 2007)
Summary.
Among the majority of inhabitants of La Paz-Bolivia (3,200-4,100 m.), the mild elevation seen in pulmonary artery pressure (PAP) has no clinical significance and is reversible on descent to lower altitude or with ...
Aymara children are protected from high-altitude-induced pulmonary hypertension
(High Altitude Medicine & Biology, 2005-02-22)
Pulmonary hypertension is a hallmark of the adaptation to ambient lack of oxygen. This assumption is also
thought to hold true for high-altitude native children,
since invasive studies showed elevated pulmonary-artery
pressure ...
The role of oxygen in prenatal growth : studies in the chick embryo
(J Physiol, 2007-10-25)
The compelling evidence linking small size at birth with later cardiovascular disease has renewed
and amplified scientific and clinical interests into the determinants of fetal growth. It is accepted
that genes and ...
Offspring of preeclamptic mothers are predisposed to hypoxic pulmonary hypertension
(High Altitude Medicine & Biology, 2005-02-22)
Adverse events in utero may predispose to cardiovascular disease in adulthood. In preeclampsia, the diseased placenta releases circulating vasculotoxic factors
that cause maternal endothelial dysfunction. These factors ...
Pulmonary-artery pressure and exhaled nitric oxide in Bolivian and caucasian high altitude dwellers
(High Altitude Medicine & Biology, 2008)
Abstract.
There is evidence
that high altitude populations may be better protected from hypoxic pulmonary hypertension than low altitude natives, but the underlying mechanism is incompletely understood. In Tibetans, ...
Response to letters regarding article, "Pulmonary and systemic vascular dysfunction in young offspring of mothers with preeclampsia"
(Circulation, 2011)
We thank Lazdam et al and Yuan et al for their interesting
comments on our study.1 Lazdam et al point out that in our study,
birth weight in offspring of mothers with preeclampsia was significantly lower than in controls, ...
Respiratory nitric oxide and pulmonary artery pressure in children of aymara and european ancestry at high altitude*
(CHEST, 2008-11-07)
Invasive studies suggest that healthy children living at high altitude display pulmonary hypertension, but the data to support this assumption are sparse. Nitric oxide (NO) synthesized by the
respiratory epithelium regulates ...
