| 目的 应用速度向量成像(VVI)技术探讨2型糖尿病(T2DM) 患者左室各壁的运动速度、应变和应变率的变化,评价VVI技术检测T2DM患者左室室壁运动改变的价值。方法 T2DM患者44例,根据临床糖尿病微血管病变出现与否分为无微血管病变组(A组)21例、合并微血管病变组(B组)23例,以VVI技术测量左室短轴方向各壁的收缩期最大径向运动速度(Vs)、最大切向应变(Smax)及最大切向应变率(SRmax)。结果 与A组比较,B组的心尖部各节段及前、后间隔中部Vs明显减低;B组 Smax 除侧壁、后壁的基底部无明显差异外,余节段较A组均明显减低;B组心尖各壁、后间隔基底段、后壁中段的SRmax明显减低。结论 VVI技术可用于2型糖尿病患者左室室壁运动的分析,是评价室壁运动的一种有效工具。 |

| Objective To study the velocity, strain and strain rate of myocardial motion using velocity vector imaging (VVI) in the type 2 diabetes mellitus patients (T2DM). Methods Forty-four T2DM patients were divided into two groups: group A (patients without microangiopathy, n=21) and group B (patients with microangiopathy, n=23). All patients underwent VVI examination, and the systolic maximum velocity (Vs), maximum strain (Smax) and maximum strain rate (SRmax) of the left ventricular walls in short axis view were measured. Results Compared with the group A, the Vs in the group B was only significantly lower in the segments of cardiac apex and the middle segments of the anterior and posterior septum (P<0.05), the Smax in the group B was significantly lower except the basal segements of lateral and posterior wall (P<0.05), and the SRmax in the group B was significantly lower in the segments of cardiac apex, the basal segment of posterior septum and the middle segment of posterior wall (P<0.05). Conclusion VVI can be used to evaluate the systolic function objectively in patients with T2DM and become a useful tool in assessing the myocardial motion. |
