Cardiac effects of endothelin receptor antagonism in endotoxemic pigs.
Myocardial depression in sepsis is frequently encountered clinically and contributes to morbidity and mortality. Increased plasma levels of endothelin-1 (ET-1) have been described in septic shock, and previous reports have shown beneficial effects on cardiovascular performance and survival in septic models using ET receptor antagonists. The aim of the current study was to investigate specific c...
متن کاملConfidence from experience: dual endothelin receptor antagonism in PAH
P ulmonary hypertension (PH) is classified into five logical treatment-based groups [1]. Pulmonary arterial hypertension (PAH) represents the first of these five groups and is further classified as idiopathic (predisposing factors having been excluded), familial or as occurring in association with certain conditions, including connective tissue disease, congenital heart disease and HIV infectio...
متن کاملDual endothelin receptor antagonism: setting standards in PAH
Endothelin (ET) has emerged as a key mediator in the pathophysiology of pulmonary arterial hypertension (PAH). The effects of ET are mediated by its binding to two receptors on endothelial and pulmonary smooth muscle cells: ETA and ETB. Blockade of both these receptors with the oral dual ET receptor antagonist, bosentan, represents an attractive treatment option for these severely compromised p...
متن کاملEndothelin receptor antagonism: what does the future hold?
The endothelins are a family (ET-1, ET-2, and ET-3) of naturally occurring polypeptides, with ET-1 being the most clinically pertinent isoform. ET-1 was formally identified in 1988, at which time it was viewed mainly as a potent vasoconstrictor; however, the biological understanding of endothelin has since rapidly evolved, and it is now appreciated that ET-1 is not only a potent vasoconstrictor...
