Abstract: | Abnormalities of diastolic function play a major role in producing the signs and symptoms of heart failure. In patients with
heart failure and reduced left ventricular systolic function, concomitant diastolic dysfunction is invariably present. In
addition, it is now well established that as many as 40% to 50% of patients with well-documented episodes of heart failure
have preserved systolic function. Doppler echocardiography provides one of the most useful clinical tools for assessing left
ventricular diastolic function and can provide diagnostic and prognostic information. The Doppler assessment of diastolic
function should be part of the routine echocardiographic evaluation of patients suspected of having heart failure. This review
focuses on the use of Doppler echocardiographic techniques to assess diastolic function. The Doppler patterns of diastolic
filling observed and their progression over time in patients with myocardial disease are described and related to changes
in the physiology of diastolic filling. In addition, Doppler echocardiographic-guided treatment strategies for heart failure
are discussed. |
