Accuracy of Tissue Doppler Echocardiography in the Diagnosis of New‐Onset Congestive Heart Failure in Patients with Levels of B‐Type Natriuretic Peptide in the Midrange and Normal Left Ventricular Ejection Fraction

Abstract

By better reflecting LV filling pressures, bedside tissue Doppler echocardiography accurately differentiates congestive HF from noncardiac cause in dyspneic patients with intermediate, nondiagnostic BNP levels and normal LV ejection fraction.
