Abstract
Echocardiographic diagnosis of radial fractional shortening or global ejection fraction fails to diagnose all patients with heart failure; about 40%, with apparently normal global systolic function, will have elevated brain natriuretic peptide (BNP) concentrations and "pure" diastolic dysfunction. Screening methods do not include assessment of left ventricular (LV) longitudinal function, however, which is a more sensitive marker of subclinical disease.
