Description Heart failure with preserved ejection fraction occurs almost with the same frequency and severity as heart failure with reduced ejection fraction. Echocardiography is the most useful non-invasive diagnostic test in the evaluation of this condition. However, no single parameter that would allow a simple assessment of the diastolic function has been discovered yet. For an accurate diagnosis, a complex echocardiographic examination must be performed to demonstrate the presence of structural and/or functional cardiac abnormalities. Structural parameters, determinants of transmitral and pulmonary venous flow velocity by pulse Doppler, and mitral annular velocity by tissue Doppler, are used to make this assessment. Also speckle track ing echocardiography and an evaluation of myocardial deformity are becoming part of an integrated approach to the assessment of diastolic function. Many other parameters are the subject of extensive clinical research.
