摘要
目的 对应用超声心动图联合组织多普勒成像(TDI)评估腹膜透析患者心功能可行性进行分析.方法 选取 2021 年 10 月～2023 年 10 月我院收治的 60 例腹膜透析患者,患者于腹膜透析治疗前后采用超声心动图联合TDI检查,评估两组左心功能(舒张末期左室后壁厚度(LVPWTd)、舒张末期室间隔(IVSTd)、左室收缩末期内径(LVDs)、左室舒张末期内径(LVDd)、左房内径(LAD)、左室射血分数(LVEF)、左室舒张末期容积(LVEDV)、左室收缩末期容积(LVESV)、左室短轴缩短率(FS)、每搏输出量(SV)].结果 治疗后,患者的LVPWTd、IVSTd、LVDs、LVDd、LAD、LVEDV、LVESV、FS、SV高于治疗前,LVEF低于治疗前(P<0.05);患者心血管不良事件发生率为 21.67(13/60),经Spearman相关性分析发现LVEF、SV与腹膜透析患者心血管不良事件发生率具有相关性(P＜0.05).结论 将超声心动图联合TDI技术应用于腹膜透析患者心功能的评估中,能为患者心功能的评估提供有益信息,有助于更全面地了解其心血管状况,从而降低心血管不良事件发生率.
Abstract
Objective:To analyze the feasibility of echocardiography combined with tissue Doppler imaging(TDI)in assessing cardiac function in peritoneal dialysis patients.Methods:A total of 60 patients with peritoneal dialy-sis(PD)who were treated in our hospital from October 2021 to October 2023 were selected,and were examined by e-chocardiography combined with TDI before and after PD to assess left ventricular function in both groups[left ventricu-lar posterior wall thickness at end-diastole(LVPWTd),interventricular septum at end-diastole(IVSTd),left ventricular diameter at end-systole(LVDs),left ventricular diameter at end-diastole(LVDd),left atrial diameter(LAD),left ven-tricular ejection fraction(LVEF),left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV),left ventricular shortening rate(FS),stroke volume(SV)].Results:After treatment,the LVPWTd,IVSTd,LVDs,LVDd,LAD,LVEDV,LVESV,FS and SV of patients were higher than those before treatment,while LVEF was lower than that before treatment(P<0.05);The incidence of cardiovascular adverse events was 21.67%(13/60).Spear-man correlation analysis showed that LVEF and SV were associated with the incidence of cardiovascular adverse events in peritoneal dialysis patients(P<0.05).Conclusion:Echocardiography combined with TDI can provide useful informa-tion for the evaluation of cardiac function in peritoneal dialysis patients,help to understand their cardiovascular status more comprehensively and reduce the incidence of adverse cardiovascular events.
