Abstract ObjectiveTo analyze the clinical diagnostic value of cardiac color Doppler ultrasonography in hypertensioninduced left ventricle hypertrophy patients with left heart failure.MethodsFrom July 2014 to July 2016,58 hypertension-induced left ventricle hypertrophy patients with left heart failure treated in our hospital were selected as the observation group.Another group of 58 healthy people visiting our hospital for physical examinations were selected as the control group during the same period.Both groups were provided with cardiac color Doppler ultrasonography.Indexes of diastolic blood pressure (DBP),systolic blood pressure (SBP),left ventricular weight(LVM),left ventricular mass index (LVMI),left ventricular fractional shortening (LVFS),left ventricular end-diastolic diameter (LVEDD),left ventricular end-systolic diameter(LVESD),left ventricular ejection fraction (LVEF),left atrial diameter(LAD),maximal blood flow velocity of opening of mitral valve at early diastolic stage (E)/maximal speed of movement of mitral valve at early diastolic stage (A)were compared between the two groups.ResultsIn the observation group,the SDP,SBP,and LVEDD were all much higher in comparison with those in the control group,with statistical differences(P<0.05).The indexes of LVM, LVMI,LVEF and LVFS were significantly higher in the observation group compared with those in the control group,with statistical differences(P<0.05).In the observation group,the peak value A was significantly higher than that in the control group,while the peak value E and E/A ratio were greatly lower than those in the control group,with statistical differences(P<0.05).In patients with gradeⅢcardiac function,the indexes of LAD,LVEDD and E/A were significantly higher than those in gradeⅡ,while LVEF was much lower than that of gradeⅡ,with statistical differences(P<0.05).Conclusion Cardiac color Doppler ultrasound can dynamically display the structure of cardiac cavity,heart beat and blood flow as well as accurately evaluate the cardiac function at advantages of no trauma and repeatable performance,which can be considered as a basis for early judgment for patients′disease condition.
