The value of troponin did not independently predict the presence of obstructive coronary disease in a scenario of acute heart failure, and the identification of the presence of obstructive coronary disease involved few revascularization procedures. This raises questions about the usefulness of pursuing the diagnosis of coronary disease in this clinical scenario.
