应用速度向量成像技术对美沙酮维持治疗者左心室功能的评价

An evaluation of left ventricular function in NMT by velocity vector imaging

目的应用速度向量成像技术对美沙酮维持治疗者左心室功能进行评价。方法选取2011年6月—2013年12月78例美沙酮维持治疗的海洛因依赖者为观察组,同期门诊体检健康人员78人为对照组,分别应用速度向量成像技术对两组人员左心室功能进行测定和分析。结果观察组受检人员在左心室前间隔基底段、前间隔中段、间隔心尖段、侧壁基底段、侧壁中段和侧壁心尖段等6个节段的舒张早期峰值运动速度和舒张早期峰值应变率均明显低于对照组(P<0.05)。结论速度向量成像技术可用于美沙酮维持治疗的海洛因依赖者左心室功能的检测。

Objective To evaluate of velocity vector imaging technology in methadone maintenance treatment patients. Methods From June to December in 2011,78 cases of heroin addicts were selected as observation group,and 78 healthy persons who received physical examination at the same period were selected as the control group.Velocity vector imaging technology was measured for both groups.Results All of early diastolic peak velocity and early diastolic max strain rate of the basement,left ventricular interval before,left ventricular apex,left ventricular wall between basement,in the left ventricular wall,the left ventricular segmental wall apex in observation group were significantly lower than that in the control group （P〈0.05）.Conclusion The velocity vector imaging technology could be applied to evaluate left ventricular function among methadone maintenance treatment patients.
