The feasibility of discontinuing digitalis-glycoside treatment was tested in 200 patients with various cardiovascular diseases who, on admission to hospital, were on maintenance digitalis. Among those with the main diagnosis of hypertension digitalis administration was discontinued without ill effect in 73%; among those with peripheral arterial obstructive disease in 64%; and among those with coronary heart disease in 33%. Discontinuing digitalis was less often justified in patients with valvar defects, cardiomyopathies, myocardial infarction or cerebrovascular insufficiency. Indications for digitalis-glycoside treatment should be more rigorously applied.
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.
