Congenital pulmonary arteriovenous fistulae, provided that they are not present in very large numbers, are best managed surgically, and there is no effective alternative management. Where pulmonary arteriovenous fistulae develop as a consequence of pulmonary hypertension it is rational to resect the fistulae if the cause of pulmonary hypertension - for example, mitral stenosis - is correctable....

Pulmonary hypertension has been observed to be elevated among end-stage renal disease and patients who are on dialysis. Several investigations, have demonstrated that, pulmonary hypertension in end-stage kidney failure patients is related to expressively enhanced mortality and morbidity. Pulmonary hypertension represents a group of comparatively erratic illnesses that causes different pulmonary...

BACKGROUND Chronic thromboembolic pulmonary hypertension after pulmonary embolism is associated with high morbidity and mortality. Understanding the incidence of chronic thromboembolic pulmonary hypertension after pulmonary embolism is important for evaluating the need for screening but is also a subject of debate because of different inclusion criteria among previous studies. We determined the...

Systemic hypertension is a pathophysiological state that is manifested as high blood pressure and is a major risk factor for stroke, ischemic heart disease, peripheral vascular disease, and progressive renal damage. Pulmonary hypertension occurs in 3 distinct forms: primary pulmonary hypertension, pulmonary hypertension of the newborn, or secondary pulmonary hypertension attributable to a varie...

In 1967 Kay et al postulated that some cases of unexplained pulmonary hypertension might be due to the ingestion of drugs or other toxic substances.' This concept, later termed dietary pulmonary hypertension,23 was advanced following the observation that the oral administration to rats of the pyrrolizidine alkaloid monocrotaline produced severe pulmonary hypertension.' There are no reports of p...

Pulmonary hypertension is a frequent complication of chronic obstructive pulmonary disease (COPD) and associated with a worse survival and increased risk of hospitalization for exacerbation of COPD. However, little information exists regarding the potential role of systemic inflammation in pulmonary hypertension of COPD. The purpose of the present study was to investigate the degree of C-reacti...

Although pulmonary arterial hypertension is usually associated with advanced stages of sarcoidosis, its occurrence in early stage disease is rare. Herein, a case of associated pulmonary arterial hypertension in the setting of Hashitoxicosis and stage II pulmonary sarcoidosis is reported. The case of associated pulmonary arterial hypertension occurred in a young female without clinically signifi...

Pulmonary hypertension is a serious disease with a poor prognosis. Pulmonary hypertension is defined by a mean pulmonary arterial pressure over 25 mm Hg at rest or over 30 mm Hg during activity. According to the recent WHO classification from 2003 pulmonary hypertension can be categorized as pulmonary arterial hypertension, pulmonary venous hypertension, hypoxic pulmonary hypertension, chronic ...

Severe, sustained pulmonary hypertension leads to pulmonary vascular obstructive disease, which is potentially fatal. But recent advances in genetics and cell biology provide insights into the pathogenesis of this disease and new treatments offer an improved quality of life and increased survival. The field is moving rapidly, and it is time to adopt a more positive and aggressive approach to th...
