Mandatory oral glucose tolerance tests identify more diabetics in stable patients with chronic heart failure: a prospective observational study.

Background: Many patients with chronic heart failure (CHF) are believed to have unrecognized diabetes, which is associated with a worse prognosis. This study aimed to describe glucose tolerance in a general stable CHF population and to identify determinants of glucose tolerance focusing on body composition and skeletal muscle strength.

Methods: A prospective observational study was set up.
