“…By contrast, Ea, E/Ea and LAVI presented unidirectional changes with worsening LV diastolic function. 14,[19][20][21][22][23][24] This pseudonormal phenomenon as LV diastolic dysfunction increases in E/A but not in Ea, E/Ea and LAVI may explain the different results between E/A and Ea, E/Ea and LAVI in the present study. In addition, previous studies found that decreased Ea and increased E/Ea and LAVI were correlated with LV diastolic dysfunction.…”

Arterial stiffness is correlated with left ventricular (LV) diastolic function as well as susceptibility to LV systolic function. Therefore, if LV systolic function is not known, the relationship between arterial stiffness and LV diastolic function is difficult to determine. A total of 260 patients were included in the study. The brachial-ankle pulse wave velocity (baPWV) and the ratio of right brachial pre-ejection period to ejection time (rbPEP/rbET) were measured using an ABI-form device. Patients were classified into four groups. Groups 1, 2, 3 and 4 were patients with rbPEP/rbET and baPWV below the median, rbPEP/rbET above but baPWV below the median, rbPET/rbET below but baPWV above the median, and rbPET/rbET and baPWV above the median, respectively. The LV ejection fractions in groups 1 and 3 were higher than those in groups 2 and 4 (Po0.001 for all). Patients in group 1 had a lower left atrial volume index (LAVI) and higher early diastolic mitral annular velocity (Ea) than patients in the other groups (Pr0.002). Patients in group 2 had a LAVI and ratio of transmitral E wave velocity to Ea that were comparable to those in groups 3 and 4. In conclusion, rbPEP/rbET had an impact on the relationship between baPWV and LV diastolic function. In patients with high rbPEP/rbET but low baPWV, low baPWV may not indicate good LV diastolic function but implies that cardiac dysfunction may precede vascular dysfunction in such patients. When interpreting the relationship between baPWV and LV diastolic function, the rbPEP/rbET value obtained from the same examination should be considered.

“…[16] MPI can be combined with TDI, and this combination eliminates the disadvantages of conventional MPI by not being affected from loading conditions and heart rate fluctuations. [27] Thus, TDI-derived MPI serves more reliable global cardiac performance. [27,28] Additionally, E/Em ratio, an important noninvasive marker of LV filling pressure, has been used increasingly in recent years.…”

Background. Insulin resistance was an independent predictor of cardiovascular mortality in uremic patients without diabetes. Rosiglitazone (ROS) improves insulin sensitivity in the liver, muscle, and adipose tissue. We prospectively investigated the effects of ROS on cardiac functions by standard (SDE) and tissue Doppler echocardiography (TDI) in continuous ambulatory peritoneal dialysis (CAPD) patients. Methods. A total of 24 CAPD patients (13 males, 11 females; mean age 42.2 ± 14.8 years) were included. Routine blood samples were examined. Left and right ventricular functions were assessed, and myocardial performance index (MPI) was calculated by SDE and TDI at baseline and after 12-month ROS therapy. Left and right atrial volumes were measured and indexed to body surface area. Results. When compared with baseline, after 12 months of ROS treatment, it was shown that early (E) and late (A) diastolic velocities of atrioventricular valves, E/A ratio, mitral Ewave deceleration time (DT), isovolumetric relaxation time (IVRT), and MPI were similar (p > 0.05). Also, no significant changes were detected in LV dimensions, LV mass index, LVEF, LA volume index, or RA volume index measured by SDE before and after ROS therapy (p > 0.05). Left and right ventricular function parameters measured by TDI including Sm, Em, Am, Em/ Am ratio, E/Em ratio, and MPI were similar. Conclusion. It was found that there was no negative effect of long-term ROS therapy on cardiac functions measured by SDE and TDI in CAPD patients.

“…Myocardial early (Em) and atrial (Am) peak velocities (cm/s) and Em/Am ratio, and Sm À Em duration (isovolumic relaxation time: IVRT) were measured, as the time interval occurring between the end of Sm and the onset of Em, were determined as diastolic measurements. On the tissue Doppler images, the time interval from the end to the onset of the mitral annular velocity pattern during diastole (a m ) and the duration of the S-wave (b m ) were measured and used to calculate the DTI-Tei index as (a m À b m )/b m [16]. All diastolic parameters were measured in three consecutive cardiac cycles and averaged.…”
