组织多普勒联合心房容积追踪技术对缩窄性心包炎心房容积的研究机制

Mechanism of Atrial Volume in Patients with Constrictive Pericarditis by Tissue Doppler Imaging Combined with Atrial Volume Tracking

目的分析组织多普勒联合心房容积追踪技术在缩窄性心包炎心房容积评估中的价值。方法选取2021年1月至2022年5月期间我院收治的50例缩窄性心包炎患者为观察组,收集同期在我院接受健康体检50例健康者为对照组,所有对象均通过心房容积追踪技术对患者心房容积、功能进行评估,通过组织多普勒对心房电-机械耦联时间、心房间和心房内传导延迟时间进行测量,分析评估结果。结果观察组LAVImax、RAVImax、LAVIpre、RAVIpre、LAVImin、RAVImin明显比对照组高(P<0.05);LAEEt、RAEEt、LAEFp、RAEFp、LAEFa、RAEFa均比对照组低(P<0.05);观察组P-ALA、P-AIAS、P-ARA和TLA、TRA、TL-R均比对照组高(P<0.05)。结论组织多普勒联合心房容积追踪技术可以准确对缩窄性心包炎心房容积和心功能进行评估,为患者临床指标提供更多参考依据。

Objective To analyze the value of tissue Doppler imaging combined with atrial volume tracking in evaluating atrial volume in patients with constrictive pericarditis.Methods 50 patients with constrictive pericarditis admitted to our hospital from January 2021 to May 2022 were selected as the observation group,Collect 50 healthy people who received physical examination in our hospital at the same time as the control group,All subjects evaluated the atrial volume and function of patients through atrial volume tracking technology,The atrial electromechanical coupling time,atrial and intra atrial conduction delay time were measured by tissue Doppler,Analyze the evaluation results.Results Observation group LAVImax、RAVImax、LAVIpre、RAVIpre、LAVImin、RAVImin Significantly higher than the control group(P<0.05)、LAEEt、RAEEt、LAEFp、RAEFp、LAEFa、RAEFa Lower than the control group(P<0.05)Observation group P-ALA、P-AIAS、P-ARA and TLA、TRA、TL-R Higher than the control group(P<0.05).Conclusion Tissue Doppler combined with atrial volume tracking technology can accurately evaluate the atrial volume and cardiac function of constrictive pericarditis,To provide more reference for clinical indicators of patients.
