Abstract:Summary: Nitroglycerin (TNG), based on electrocardiographic evidence, has been shown to reduce myocardial ischemia, but its effect on morphometrically and enzymatically estimated infarct size has not been defined. Accordingly, coronary occlusion was produced in 50 conscious dogs without LV failure. Twenty-five received TNG (200-300 pg/min i.v. for 8 h) and the results compared with those in 25 untreated dogs. Coronary blood flow was measured with I4'Ce, 85Sr, and 95Nb (9 pm) after occlusion before TNG, 30 min … 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.
