| 摘 要： | 目的 探讨速度矢量成像(VVI)评价2型糖尿病亚临床左心室收缩功能不全的价值.方法 本研究受试对象分3组:单纯糖尿病组(DM)29例;糖尿病合并高血压组(DM & HP)26例;健康对照组30例.应用Sequoia 512超声诊断仪及VVl分析软件,对85例受试者左心室6个室壁16节段心肌长轴方向的收缩期速度、应变、应变率及达峰时间进行分析.结果 单纯糖尿病组及糖尿病合并高血压组的心肌收缩期速度、应变和应变率均明显低于正常对照组(P<0.01);糖尿病合并高血压组收缩期心肌速度、应变和应变率低于单纯糖尿病组(P<0.05).结论 VVI技术能够客观、敏感地反映糖尿病患者亚临床左心室长轴收缩功能不全.

| Abstract: | Objective To assess subclinical left ventricular systolic dysfunction in patients with diabetes mellitus (DM) by velocity vector imaging (VVI). Methods In 29 patients with pure DM, 26 patients with DM and hypertension (DM&HP) and 30 healthy subjects, longitudinal left ventricular systolic myocardial velocity, strain, strain rate, and peak time of velocity (PTV), strain (PTS), strain rate (PTSR) were obtained with VVI. Results The systolic myocardial Vmax, Smax and SRmax were significantly lower in pure DM and DM&HP group than in the control group (P<0.01), and were the lowest in DM&HP group (P<0.05). Conclusion VVI could objectively and sensitively detect subclinical left ventricular systolic dysfunction of DM. |
