| 目的:使用二维斑点追踪技术，探索透析患者左房与功能的改变，以及不同透析方式对左房容积和功能的影响。方法腹膜透析患者42例，血液透析患者38例， GFR>60ml/min·1.73m2患者50例，作为对照组。对以上患者行传统超声心动图检查以及左房斑点追踪，比较透析患者与对照组之间左房容积和功能的差异，以及腹膜透析患者与血液透析后患者之间左房容积和功能的差异。结果：血液透析组左房容积参数（包括LAVI 、LAV max 、LAV min、LAV pre-A）均明显大于对照组。腹膜透析组LAVI及LAV pre-A显著大于对照组。。左房功能参数方面，透析组（包括腹膜透析和血液透析）左房通道功显著低于对照组；腹膜透析组左房收缩功能显著高于对照组，血液透析组左房收缩功能也大于对照组，但不满足统计学差异。透析组储存功能与对照组相比有减低的趋势，但差异不显著，不具有统计学意义。左房峰值应变率、左房总排空率、左房主动排空率、左房被动排空率均无显著性差异。血液透析组（非透析日）左房功能与腹膜透析组（非透析日）左房功能之间无显著性差异。结论：⑴与对照组相比，透析患者左房通道功能显著降低，左房收缩功能代偿性增强；⑵血液透析患者（非透析日）与腹膜透析患者左房功能参数之间没有显著性差异；⑶与对照组相比，透析患者左房容积显著增大，血液透析患者左房扩大更为明显。（4）与传统左房容积参数LAVI相比，斑点追踪可以获得更全面、更细致、更多的左房容积参数。 |

| Abstract: |
| Objective: Using Two-dimensional speckle tracking technology to explore the changes of left atrium and function in dialysis patients and the effects of different dialysis methods on left atrial volume and function. Method: 42 cases of peritoneal dialysis, 38 cases of hemodialysis and 50 cases whose GFR>60ml/min·1.73m2 were treated as control group. Traditional echocardiography and left atrial speckle tracking were performed on the above patients, and the differences in left atrial volume and function between dialysis patients and control group were compared, as well as the differences in left atrial volume and function between peritoneal dialysis patients and hemodialysis patients. Result: The left atrial volume parameters (including LAVI, LAV Max, LAV min, and LAV pre-a) of the hemodialysis group were significantly higher than those of the control group. LAVI and LAV pre-a in peritoneal dialysis group were significantly higher than those in control group. In terms of left atrial function parameters, left atrial conduit function in the dialysis group (including peritoneal dialysis and hemodialysis) was significantly lower than that in the control group. The left atrial systolic function of the peritoneal dialysis group was significantly higher than that of the control group, and the left atrial systolic function of the hemodialysis group was also higher than that of the control group, but did not meet the statistical difference. Compared with the control group, the reservior function of the dialysis group showed a trend of decrease, but the difference was not significant. There was no significant difference in peak strain rate, total displacement rate, active displacement rate and passive displacement rate.There was no significant difference in left atrial function between hemodialysis group (non-dialysis days)and peritoneal dialysis group . Conclusion: （1）compared with the control group, left atrial conduit function of dialysis patients was significantly reduced, but left atrial contraction function was enhanced. （2）There was no significant difference between hemodialysis patients with peritoneal dialysis patients in left atrial function parameters. （3）Compared with the control group, the left atrial volume of patients receiving dialysis significantly increased, and left atrial enlargement was more obvious in hemodialysis patients. (4) compared with the conventional left atrial volume parameter LAVI, speckle tracking can obtain more comprehensive, detailed and more left atrial volume parameters. |
