The authors developed and tested a dual stress magnetic resonance (MR) imaging protocol to evaluate myocardial perfusion, function, and hibernation. The technique was well tolerated, and high-quality images were achieved. The comprehensive information obtained can be used to guide clinical management decisions regarding coronary artery revascularization procedures. This protocol offers a one-stop assessment of patients with coronary artery disease with use of a clinical MR imager.
A case of dothiepin poisoning complicated by cardiogenic shock is described. Hypotension was resistant to conventional inotropes but responded rapidly to high-dose intravenous glucagon. Glucagon should be considered as a useful therapeutic positive inotrope and a potentially antiarrhythmic agent in severe tricyclic antidepressant overdose.
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.
