Abstract:
Objectives By measuring left ventricular diastolic function and arterial stiffness,this study aims to probe into the effect of diabetes mellitus(DM) on left ventricular diastolic function and arterial stiffness,and evaluate the correlation between left ventricular diastolic funotion and arterial stiffness.Methods Seventy-six inpatients were enrolled.According to their coronary angiography,OGTF test results and past history of DM,patients were divided into controlled,CHD(coronary heart disease with no DM),and CHD+DM groups.Through invasive hemodynamic monitoring during left ventricular angiography,left ventricular end-diastolic pressure(LVEDP)and tan index were collected.Carotid-femoral pulse wave velocity(c-f PWV),reflected wave augmentation index (AIx@75) and other data reflecting the degree of arterial stiffness were collected bedside with non-invasive means.SPSS 18.0 was used for statistical analysis.Results No significant difference was found between groups for LVEDP,tau index,and AIx@75.In terms of c-f PMV,The CHD+DM group(8.79±1.59)cm/s differed significantly from the CHD group (7.43±1.42)cm/s and the controlled group(6.83±1.14)cm/s.No correlations were found between c-f PMV and LVEDP or tau index.A positive correlation was found between AIx@75 and tau index.Conclusions Compared with the controlled group and CHD patients with no DM,CHD+DM patients show worse arterial stiffness with no difference in ventricular diastolic function.There is a positive correlation between arterial stiffness and diastolic dysfunction.
