Abstract:Background Two mechanisms that contribute to pulmonary hypertension after acute pulmonary embolism (PE) are vascular obstruction and vasoconstriction. Vasoconstriction is influenced by NO release. We focused on NO synthase activity, production of NO oxidative products (NOx) and effect of phosphodiesterase‐5 (PDE‐5) blockade by sildenafil on pulmonary hypertension after PE.
Methods Using the model of in vivo pulmonary embolism we measured changes of perfusion pressure in isolated rat lungs after blockade of NO‐… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
