Methods Collecting 50 cirrhotic patients who were divided into Child A, B and C classes and 30 healthy subjects whose age, sex and weight matched with cirrhotic patients. Ultrasonography was performed to obtain the conventional ultrasonic parameters (LAAPD, IVST, LVPWT, LVEDD, LVESD, LVEF), and three-dimensional moving images. Qlab software was used to obtain the 17-segmental volume-time curves and left ventricular end-diastolic volume (LVEDV), end-systolic volume (LVESV), ejection fraction (LVEF). The standard deviation and the maximal difference of the time to the point with minimal systolic volume of 16, 12, 6 segments. The above quantitative parameters were corrected by heart rate.
Results Between cirrhosis and control group, there were statistical differences of heart rate, Systolic arterial pressure, Diastolic arterial pressure and pulse pressure (t=-5.635, 4.208, 2.183, -2.308, all P<0.05). LAAPD by 2DE in patients with cirrhosis was larger than control group, while IVST was thicker (t=-6.918, -2.940, both P<0.05). The RT-3DE quantitative parameters (Tmsv16-SD, Tmsv12-SD, Tmsv6-SD, Tmsv16-Dif, Tmsv12-Dif, Tmsv6-Dif, Tmsv16-SD%, Tmsv12-SD%, Tmsv6-SD%, Tmsv16-Dif%, Tmsv12-Dif%, Tmsv6-Dif?%, LVEDV, LVESV) have statistically differences between the two groups (t=-2.408, -3.142, -2.788, -2.761, -2.610, -2.507, -3.125, -3.725, -3.593, -2.384, -3.763, -3.657, -4.291, -4.388, all P<0.05). Comparing different cirrhosis subgroup with control group, the RT-3DE quantitative parameters (Tmsv16-SD, Tmsv12-SD, Tmsv6-SD, Tmsv16-Dif, Tmsv12-Dif, Tmsv6-Dif, Tmsv16-SD%, Tmsv12-SD%, Tmsv6-SD%, Tmsv16-Dif%, Tmsv12-Dif%, Tmsv6-Dif%, LVEDV, LVESV, LVEF) have statistically differences (F=7.563, 12.544, 7.482, 5.211, 7.197, 5.131, 6.232, 11.327, 7.233, 4.296, 8.906, 8.563, 10.904, 9.809, 0.382, all P<0.05). With the aggravation of cirrhosis, LVEF showed the decreasing tendency, while the other RT-3DE parameters (Tmsv16-SD, Tmsv12-SD, Tmsv6-SD, Tmsv16-Dif, Tmsv12-Dif, Tmsv6-Dif, Tmsv16-SD%, Tmsv12-SD%, Tmsv6-SD%, Tmsv16-Dif%, Tmsv12-Dif%, Tmsv6-Dif%, LVEDV, LVESV) showed the tendency of increasing.
