Abstract
Left ventricular (LV) diastolic dysfunction with
preserved ejection fraction is frequently encountered in
clinical practice. However, the relations between LV filling
patterns and myocardial function by using two-dimensional
(2D) speckle tracking imaging are not well known. One
hundred thirteen individuals (mean age 59 ± 12 years),
referred for a clinically indicated echocardiogram, underwent
standard and 2D strain echocardiography. The subjects
were divided into groups on the basis of diastolic
function by using standard Doppler indices, and we compared
2D strain/strain rate parameters between groups.
Subjects with mild to moderate LV diastolic dysfunction
showed a high left atrial volume index (LAVI) and early
mitral inflow to annular velocity ratio. With regard to 2D
strain/strain rate, the severity of diastolic dysfunction was
associated with low peak strain, and low systolic and early
diastolic strain rate of longitudinal, circumferential and
radial deformations, whereas the late diastolic strain rate
was not. In multivariate analysis, LAVI and circumferential
early diastolic strain rate were most associated with the
severity of diastolic dysfunction, although longitudinal and
circumferential peak strains were also of significant correlation.
In addition to LAVI, the circumferential early
diastolic strain rate would be a useful parameter in the
assessment of the severity of diastolic dysfunction with
preserved ejection fraction.
