Abstract

Endothelins (ET), a family of three peptides of strong vasoconstrictive properties, participate in the regulation of vascular tone and blood flow. The synthesis and degradation of the ET predominantly take place in the pulmonary vasculature. Elevated plasma ET levels were reported in various forms of arterial pulmonary hypertension including chronic thromboembolic pulmonary hypertension (CTEPH). Moreover, clinical studies with nonselective ET receptor antagonist - bosentan reported improvement in functional class in patients with CTEPH. It has been suggested that endothelins may play an important role in acute pulmonary thromboembolism (APE). However, further studies are necessary to verify these observations. In the current paper we discuss a potential role of endothelins in CTEPH and APE.
