0.05).Both of them had a linear correlativity,correlative coefficient closed to 1.Conclusions Coronary artery endothelial function and brachial artery endothelial function had a high linear correlativity.

To evaluate the left ventricular diastolic function with Doppler and 2D echocardiography in patients with mild and moderate hypertension. 202 patients with hypertension were involved in this study. The parameters of Doppler and 2D echocardiography were compared with clinical materials of the patients. The results of this study showed that age, diabetes, left ventricle hypertrophy and duration of hypertension were related to the left ventricular diastolic function, whereas hyperlipidmia, smoking and alcohol drink had less effect on left diastolic function. The results of this study suggested that there were diastolic dysfunction in patients with hypertension, and Doppler and 2D echocardiography could be used to detect left ventricular diastolic function.

Objective To assess the changes of the cardiac function of the patients with myocardial infarction(MI) after the coronary revascularization(CRV) by 2D echocardiography and Doppler tissue imaging(DTI).The effects of CRV on cardiac function were explored.Methods The global and regional wall functions were quantitatively analyzed in 49 patients with MI by 2D echocardiography and DTI(Aspen imaging systems).Results The regional function was improved prior to the global function in patients with MI after successful CRV.Conclusions CRV is one of the important factors for the cardiac function improvement in patients with MI.

ATM: To investigate the relationship between the oculus dominans and the eye with higher diopter among myopes, and to study the difference between the Worth 4 dot test and hole-in-the-card test.
METHODS: Totally 125 cases were divided into two groups as physiogenic anisometropic group and pathological anisomitropic group according to the degree of binoculus anisometropy. Worth 4 dot test and hole-in-the-card test were used to distinguish oculus dominans respectively based on medical optometry.
RESULTS: In physiogenic anisometropic group, the oculus dominans and the eye with higher diopter among myopes had significant relationship by hole-in-the-card test (Z = -4. 057, P<0. 01) and Worth 4 dot test (Z=-3. 558, P<0. 01). However, in pathological group, No statistical significance was between two tests (P>0. 05); distinguish the oculus dominans had no statistically significant difference between the Worth 4 dot test and hole-in-the-card test (n=125, P>0. 05).
CONCLUSION:The oculus dominans is determined by gene or formed during juvenile period, then myopia anisometropic may affect the choice of that. The Worth 4 dot test has some reference significance for observing oculus dominans.

Objective　To examine the left ventricular diastolic function of patients with coronary artery diseases by noninvasive echocardiography and invasive coronary angiography.Methods　Mitral and pulmonary venous Doppler signals were recorded by the continuous wave Doppler technique in 62 patients, both coronary angiography and left ventricle pressure were measured. Patients were divided into normal and abnormal groups based on coronary angiography.Results　Left ventricular end diastolic pressure (LVEDP) (17.6 mm Hg vs 13.2 mm Hg,P<0.05),the left ventricular negative Δp/Δt before atria contraction ［-(224.63±52.18),-(87.81±24.41),P<0.05］,and the elevated value of left ventricular pressure derived from atria contraction ［(6.66±0.92)mm Hg vs (0.96±1.87)mm Hg,P=0.0094］ in abnormal group were more than those in the normal. The ratio of slope in pulmonary vein and mitral A wave peak was less in normal group than that in the abnormal (5.10±0.31 vs 4.12±0.20,P＝0.0106). But the isovolume relaxation parameters had no differences between the two groups.Conclusions　Coronary arter ischemia is an important cause of left ventricular impaired relaxation aggravation and stiffness, the diastolic abnormalities existed in the whole diastolic duration. Except ischemia, other factors also could cause relaxation disfuction and even elevate the LVEDP.
