AGENT FOR IMPROVING DECREASED EXERCISE TOLERANCE IN CHRONIC HEART FAILURE

摘要

Disclosed is an agent for improving the decreased exercise tolerance in chronic heart failure, which comprises an allosteric hemoglobin modifier (e.g., efaproxiral) as an active ingredient. The agent has less influence on the cardiac function, can improve the decreased exercise tolerance in chronic heart failure, and can improve the QOL in a patient suffering from chronic heart failure.
