| 目的 应用多普勒组织成像(DTI) 技术测量三尖瓣环运动速度,评价冠心病患者的右室功能。方法 分别对A组19 例单纯右冠状动脉狭窄者、B 组30 例左冠状动脉狭窄者和C 组36 例正常对照者应用DTI 从心尖四腔切面测定三尖瓣环的右室侧壁和室间隔的收缩期(Sa) 、舒张早期( Ea) 和舒张晚期(Aa) 运动速度峰值,并进行显著性检验。结果 A 组和B 组的Sa 和Ea 均低于正常组( P < 0. 05～0. 01) , 但A 组Ea/ Aa 之比显著低于正常组( P < 0. 01) ,而B 组的Ea/ Aa 之比和两组的Aa 与正常组相比无统计学差异( P > 0. 05) 。证明冠状动脉病变确实影响了右室壁的运动功能。结论 DTI 技术测定三尖瓣环运动速度可作为评价冠心病右室功能的新方法。 |

| Objective To evaluate the right vent ricular systolic and diastolic functions of patient s with coronary artery dis-ease (CAD) using t ricuspid annular motion velocities measured by Doppler tissue imaging (DTI) . Methods The study in-cluded 49 consecutive patient s underwent coronary angiography. Group A included 19 patient s with right coronary stenosis( ≥70 % diameter reduction) , Group B , 30 patient s with left coronary stenosis ( ≥70 % diameter reduction) and Group C ,36 normal subject s. The peak systolic velocity (Sa) , peak early diastolic velocity ( Ea) and late diastolic velocity (Aa) weremeasuredat tricuspid annular sties from apical 42chamber views. Results Compared with the normal subjects , the Group Aand B had reduced Sa , Ea ( P < 0. 05 - 0. 01) , but Group A had significantly reduced Ea/ Aa ratio (P < 0. 01) . Ea/ Aa ratio inGroup B , Aa in Group A and B was not significantly different . Conclusion Quantification of tricuspid annular motion veloci-ties measured by DTI provides a new method to assess right vent ricular function in patients with CAD. |
