摘要
目的应用速度向量成像(VVI)技术定量评估肥厚型心肌病(HCM)患者的左心房容积和功能,并探讨其临床价值。方法选择2019年3月至2020年9月在丽水市中心医院诊断为HCM的患者36例(HCM组),另择同期健康体检者30例(对照组),行常规超声心动图检查,应用VVI技术获取左心房功能及容积等相关指标并进行比较。结果HCM组二尖瓣口舒张早期峰值流速与舒张晚期峰值流速比值(E/A)、左心房整体纵向应变峰值(LA-GLPS)、收缩期峰值应变率(SRs)、舒张早期峰值应变率(SRe)、舒张晚期峰值应变率(SRa)、舒张早期排空率峰值(dv/dte)、左心房被动射血分数(LAPEF)及左心房总射血分数(LATEF)均低于对照组,而左心房前后径(LAD)、舒张末期室间隔厚度(IVSd)、收缩期速率峰值(dv/dts)、舒张晚期排空率峰值(dv/dta)、左心房最大容积(LAVmax)、左心房最小容积(LAVmin)、左心房收缩前容积(LAVp)、左心房最大容积指数(LAVImax)、左心房主动射血分数(LAAEF)均高于对照组,差异均有统计学意义(均P<0.05)。结论VVI技术可以定量、准确评估HCM患者的左心房容积及功能变化,有利于指导临床进行早期干预。
Objective To evaluate the application of velocity vector imaging(VVI)in quantitative assessment of the left atrial(LA)volume and function in patients with hypertrophic cardiomyopathy(HCM).Methods Thirty six HCM patients and 30 healthy subjects(control group)were enrolled in the study.VVI were performed in all subjects and the LA volume and function were calculated and compared between the two groups.Results Compared with the control group,E/A,LA-GLPS,SRs,SRe,SRa,dv/dte,LAPEF and LATEF in HCM group were decreased,while LAD,IVSD,dv/dts,dv/dta,LAVmax,LAVmin,LAVp,LAVImax and LAAEF were increased(all P<0.05).Conclusion VVI is a promising approach in assessing LA volume and function of HCM patients.
