摘要
目的:分析扩张型心肌病患者常规超声心动图及二维斑点追踪参数表现。方法:回顾性收集2020年1月—2023年4月期间于宜兴市人民医院心脏超声科就诊的61例扩张型心肌病患者的临床资料,将其纳为研究组,另收集同期61例排除心脏病变患者的临床资料纳为对照组,两组均行超声心动图检查与二维斑点追踪,比较两组常规超声心动图指标以及二维斑点追踪参数(包括应变值、应变率),同时根据患者左房功能指标进一步将研究组分为左室射血分数(LVEF)<35%和≥35%两个亚组,探讨左房功能与二维斑点追踪参数之间的关联性。结果:经超声心动图检查,研究组左房内径(LAD)均大于对照组,LVEF水平低于对照组(P <0.05);二维斑点追踪结果显示,研究组收缩期应变(Ss)、舒张晚期应变(Sa)均低于对照组,收缩期应变率(SRs)、舒张晚期应变率绝对值(|SRa|)均低于对照组(P <0.05);研究组中,LVEF <35%患者LAD显著大于LVEF≥35%患者,Ss、Sa、SRs、|SRa|均显著低于LVEF≥35%患者(P <0.05);进一步经Pearson相关性分析,显示左房功能与二维斑点追踪参数之间具有较好的相关性(P <0.05)。结论:扩张型心肌病患者常规超声显示LAD偏大,LVEF偏低,二维斑点追踪参数显示,Ss、Sa、SRs、|SRa|偏低,且LVEF与LAD、Ss、Sa、SRs、|SRa|之间存在一定关联性,能较好评估左房功能,具有临床参考价值。
Objective To analyze the conventional echocardiography and two-dimensional speckle tracking parameters in patients with dilated cardiomyopathy.Methods The clinical data of 61 patients with dilated cardiomyopathy(study group)who were treated in Yixing People's Hospital from January 2020 to April 2023 were collected retrospectively.At the same time,the clinical data of 61 patients without heart disease(control group)were collected.Both groups received echocardiography and two-dimensional speckle tracking.The conventional echocardiographic indicators and two-dimensional speckle tracking parameters were compared between the two groups.Patients in the study group were divided into the left ventricular ejection fraction(LVEF)<35%group and LVEF≥35%group.The correlation between left atrial function and two-dimensional speckle tracking parameters was discussed.Results Echocardiography found that left atrial diameter(LAD)in the study group was significantly greater than that in the control group,and LVEF was significantly lower than that in the control group(P<0.05).The results of two-dimensional speckle tracking showed that the systolic strain(Ss)and late diastolic strain(Sa)in the study group were significantly lower than those in the control group(P<0.05),while the systolic strain rate(SRs)and absolute value of late diastolic strain rate(|SRa|)were significantly lower than those in the control group(P<0.05).In the study group,LAD of patients with LVEF<35%was significantly larger,while Ss,Sa,SRs and|SRa|were significantly lower as compared to patients with LVEF≥35%(P<0.05).Pearson correlation analysis found that left atrial function was correlated with two-dimensional speckle tracking parameters(P<0.05).Conclusion For patients with dilated cardiomyopathy,conventional echocardiography shows larger LAD and lower LVEF,while two-dimensional speckle tracking shows lower Ss,Sa,SRs and|SRa|.There is a certain correlation between LVEF and LAD,Ss,Sa,SRs,|SRa|,which provides reference for clinical practice.
