Objective To evaluate of left ventricular diastolic function in patients with diabetes mellitus by tissue doppler imaging.Methods Thirty patients with diabetic and 26 healthy subjects were studied in this study.Early diastolic velocity and late diastolic velocity were measured on six sites of mitral annulus by tissue doppler imaging.The mean peak Ouvelocity(mVe、mVa) and ratio(mVe/mVa) were calculated.Results Compared with healthy subjects,there was a significant difference in those parameters of mVe,mVa and mVe/mVa(P0.01).Conclusion Tissue doppler imaging can quantify diastolic velocity on mitral annulus and detect abnormal left ventricular diastolic function in early.It provides early evidence for diabetic cardiomyopathy.

Objective To explore the correlation between age and left and right ventricular diastolic function indexes measured by tissue Doppler imaging in normal individuals.Methods Fifty and seven healthy participants aged from 16 to 74 years were included in the study.Each participant underwent pulsed wave Doppler examination of mitral inflow,tricuspid inflow,then underwent tissue Doppler imaging of the mitral,tricuspid annulus.Results There was good correlation between age and ventricular diastolic function indexes measured by tissue Doppler imaging(r=-0.73,P0.001).Conclusion This study shows that age has important influence on ventricular diastolic function indexes measured by tissue Doppler imaging in normal individuals and should be considered in the evaluation of left and right ventricular diastolic function

Purpose of review The development of effective enzyme replacement/enhancement therapy makes of clinical relevance considering Fabry disease in the differential diagnosis of patients with hypertrophic cardiomyopathy. In particular the opportunity to significantly modify the clinical progression of the disease has reinforced the need for early diagnosis of Fabry cardiomyopathy. Recent findings The study with tissue Doppler of Fabry patients with endomyocardial biopsy-proven cardiac involvement showed a reduction of both diastolic and systolic myocardial velocities recorded at septal and lateral corners of mitral annulus. Tissue Doppler abnormalities were present not only in patients with left ventricular hypertrophy but also in younger patients with normal cardiac wall thickness and represent the first sign of myocardial damage. Furthermore tissue Doppler studies have been shown useful in detecting cardiac involvement in female carriers with no systemic manifestations of Fabry disease. In patients already submitted to enzyme-replacement therapy tissue Doppler and strain rate imaging represent useful noninvasive tools in assessing treatment efficacy. Summary Tissue Doppler imaging can provide early detection of cardiac involvement in Fabry disease and represents the most accurate and sensitive noninvasive tool for the diagnosis of myocardial dysfunction and for the assessment of cardiac improvement during enzyme replacement therapy. The detection of tissue Doppler abnormalities in female carriers may represent a hint for an invasive assessment of cardiac involvement.

Background: Tissue Doppler imaging is a technique that complements the analysis of left ventricular (LV) diastolic function. Some factors may influence these parameters, however the true influence of age on Tissue Doppler velocities remains unclear. Objective: To compare the indices of diastolic function derived from tissue Doppler imaging in hypertensive and non-hypertensive elderly individuals. Methods: Subjects aged over 60 years, divided into two groups were studied: a control group (GC) without cardiovascular comorbidities and a hypertensive group (HAS). Left ventricular systolic and diastolic function (conventional and tissue Doppler) was assessed, and measurements of left atrial volumes and LV mass were obtained. Results: The group consisted of 56 subjects (70.1 ± 6.6 years), 23 (41.1%) in the GC and 33 (58.9%) in the HAS. Except for LV hypertrophy, more frequent in the HAS group compared to HG (34.4% versus 4.8% respectively; p=0.017), all structural echocardiographic findings were similar. Tissue Doppler analysis revealed no differences between the groups (septal e’: 8.0 ± 1.5 vs. 7.2 ± 1.9 cm/s; p=0.083 and lateral e’: 9.8 ± 2.2 versus 8.7 ± 2.0 cm/s; p=0.074, respectively, for GC and HAS). A longer E-wave deceleration time was observed for HAS group (253 ± 62 versus 208 ± 36 ms in GC; p=0.003). Conclusion: In the analysis of diastolic function in elderly, tissue Doppler imaging was not able to discriminate hypertensive individuals, with the greatest potential for the occurrence of diastolic dysfunction, to the non-hypertensive individuals.The E-wave deceleration time proved to be a valuable parameter in this population.

Objective To assess the left ventricular diastolic function in hypertension patients without left ventricular hypertrophy by using tissue Doppler imaging(TDI).Methods 23 hypertension patients without left ventricular hypertrophy were enrolled.The early diastolic velocity(Ea),the late diastolic velocity(Aa) and systolic velocity(Sa) were observed with TDI.The peak early(E) and late(A) transmitral filling velocities,their ratio(E/A),isovolumic relaxation time(IVRT) and deceleration time(DT) were measured with PDI.All the data were compared with those in nineteen normal controls.Results As compared to the control group,t here was significantly statistical difference between E,A,E/A,IVRT,DT,Ea and Ea/Aa(P0.001).Conclusion TDI were reliable methods to assess left ventricular diastolic function in hypertension patients.

Aim:To assess left ventricular function using Tei Index by Tissue Doppler Imaging in patients with rheumatoid arthritis(RA). Methods:Sixty patients with RA and 56 healthy persons were included in this study. Tissue movement curves of Mitral annulus were collected by TDI. peak systolic velocity(Sa),peak early diastolic velocity(Ea),peak end diastolic velocity(Aa)were measured,and Ea / Aa ratio were calculated. Tei index was also calculated from the results of TDI. Results: mitral annular Sa,Ea / Aa decreased(P 0. 05) while Tei index elevated(P 0. 05)in RA group compared with normal control group. There were no significant differences in Ea,Aa or eiection fraction(EF)between two groups(P 0. 05). Conclusion:Left ventricular dysfunction in patients with RA was caused by both diastolic function and systolic function reduced. The Tei index come from TDI is an ideal indicator to assess left ventricular function in patients with RA.
