全容积三维超声心动图评估冠心病患者左心室局部结构和收缩功能的临床意义

The clinical significance of left ventricular regional structure and systolic function by full volume three dimensional echocardiography in patients with coronary artery disease

目的 研究全容积三维超声评估冠心病患者左心室局部结构和收缩功能的临床意义.方法 临床纳入我院2014年3月至2016年3月期间收治的42例冠心病患者作为研究组,另选取40例同期来我院进行体检的健康志愿者作为对照组.两组对象均采用全容积三维超声心动图（FV-3DE）检查,对两组对象左心室局部舒张末期容积（REDV）、局部收缩末期容积（RESV）及局部心搏量（RSV）情况进行对比,观察左心室17节段局部射血分数（REF）情况.结果 术前研究组REDV（124.19±18.43）ml、RESV （63.28±20.14）ml、RSV（48.92±2.68）％,与对照组（86.32±12.35）ml、（34.25±5.63）ml、（60.43±3.62）％比较差异有统计学意义（P＜0.05）.术后研究组REDV（112.56±16.95）ml、RESV（50.29±10.47）ml、RSV（55.14±2.89）％,比术前有较大改善,与对照组（86.32±12.35）ml、（34.25±5.63）ml、（60.43±3.62）％比较差异有统计学意义（P＜0.05）.术前研究组左心室17节段RSV与对照组比较,除中段侧壁、后壁,室间隔,心尖段室间隔和心尖帽外,其余节段差异均有统计学意义（P＜0.05）.术后研究组基底段前间壁、后壁、室间隔改善明显,与对照组比较未见统计学差异（P＞0.05）;其余节段多数明显改善,与对照组比较差异有统计学意义（P＜0.05）.结论 FV-3DE对冠心病患者心脏局部容积和心脏功能具有较好的评估效果,对临床预测冠心病患者病情及心功能评估具有重要作用和意义,值得临床应用.

Objective To investigate the effects of total solvent LDK ultrasound on the left ventricular regional structure and systolic function in patients with coronary heart disease.Methods 42 patients with coronary heart disease treated in our hospital from March 2014 to March 2016 were selected as the study group,and 40 healthy volunteers who came to our hospital for the same period were selected as the control group.Both of the two groups used full volume three-dimensional echocardiography （FV-3DE） examination,left ventricular regional end diastolic volume （REDV）,local end systolic volume （RESV） and regional stroke volume （RSV） were compared,and the local left ventricular ejection fraction（REF） of 17 segments of the situation were observed.Results Before the operation,the levels of REDV （124.19±18.43）ml,RESV （63.28±20.14）ml and RSV （48.92±2.68）% in the study group were significantly different from those in the control group （86.32±12.35）ml,（34.25±5.63）ml,（60.43±3.62）% （P〈0.05）.After operation,the levels of REDV （112.56± 16.95）ml,RESV （50.29± 10.47）ml and RSV （55.14±2.89）% in the study group were improved greatly,but it was still different from that in the control group（86.32±12.35）ml,（34.25±5.63）ml,（60.43±3.62）%（P〈0.05）.Before operation,the left ventricular 17 segment RSV in the study group was compared with the control group,except for the middle wall,posterior wall and interventricular septum,and the interventricular septum and the apical cap,there were differences in the other segments（P〈0.05）.After the operation,the study group with basal segment of the anterior wall,posterior wall and septum were improved,had no difference with the control group（P〉0.05）.Most of the other segments were significantly improved,but there was still a difference comparing with the control group （P〈0.05）.Conclusion FV-3DE has a good effect on the evaluation of regional volume and heart function in patients with coronary heart disease,and plays an important role in coronary disease and heart function in clinical evaluation,it is worthy of clinical application.
