| 摘 要： | 目的探讨三维斑点追踪成像评估不同室壁厚度主动脉瓣狭窄患者左室收缩功能的临床价值。方法选取45例左室射血分数(LVEF)正常的重度主动脉瓣狭窄患者,按照室壁厚度分为狭窄组(A组)20例和狭窄壁厚组(B组)25例,另选取年龄、性别相匹配的健康志愿者30例为正常对照组。均行常规及三维超声心动图检查,测量LVEF、左室心肌质量(LVM),以及左室整体峰值纵向应变(GLS)、圆周应变(GCS)、面积应变(GAS)及径向应变(GRS),并计算左室心肌质量指数(LVMI),比较各组上述参数的差异。结果A、B组GLS、GRS均较正常对照组显著降低,GCS、LVMI均较正常对照组显著增加,差异均有统计学意义(均P<0.01);各组LVEF、GAS比较差异均无统计学意义;A、B组GLS比较差异有统计学意义(P<0.01),余参数比较差异均无统计学意义。GLS、GRS、GCS、GAS与LVMI均呈正相关(r=0.58、0.31、0.29、0.43,均P<0.05)。结论应用三维斑点追踪成像可评估LVEF正常的主动脉瓣狭窄患者其左室收缩功能受损,且室壁越厚,心肌质量越大,心功能受损越明显。 |

| Abstract: | Objective To explore the clinical value of three-dimensional speckle tracking imaging in evaluating leftventricular systolic function in patients with aortic stenosis with different wall thickness.MethodsForty-five patients withsevere aortic stenosis with normal left ventricular ejection fraction(LVEF)were divided into stenosis group(20 cases,group A)and stenosis wall thickness group(25 cases,group B)according to the wall thickness.Another 30 healthy volunteers matched inage and sex were selected as control group.Conventional and three-dimensional echocardiography were performed to measureLVEF,left ventricular myocardial mass(LVM),global peak longitudinal strain(GLS),global circumferential strain(GCS),globalarea strain(GAS),global radial strain(GRS),left ventricular mass index(LVMI).The differences of the above parameters of eachgroup were compared.Results GLS,GRS were significantly reduced,and GCS,LVMI were significantly increased in group A andgroup B compared with the normal control group.The differences were statistically significant(all P<0.01).There were nosignificant difference in the comparison between the LVEF and GAS in each group.There was significant difference in the GLS comparison between A group and B group(P<0.01),but other parameters were no significant difference.GLS,GRS,GCS and GAS were positive correlated with LVMI(r=0.58,0.31,0.29,0.43,all P<0.05).Conclusion Three-dimensional speckle trackingimaging can assess impaired left ventricular systolic function in patients with normal LVEF aortic stenosis,and the cardiacfunction impaired is more obvious in patients with increased ventricular wall thickness and heavier myocardial mass. |
