Left main or proximal left anterior descending coronary artery disease: detection by echocardiographic evaluation of interventricular septal function during exercise
Abstract:Forty patients with coronary artery disease were studied prospectively to investigate whether stenosis of the left main (LMCA) or left anterior descending coronary artery, proximal to the first septal branch (proximal LAD), could be detected by M-mode echocardiography during exertion. The interventricular septum was visualized in 30 of the patients during bicycle exercise in the semisupine position, all with simultaneous occurrence of electrocardiographic evidence of myocardial ischaemia. Fifteen of these had … 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.
