摘　　要：目的研究对比静息状态下镜像右位心老年人与正常老年人的心功能指标的差异,为相应老年人镜像右位心患者心功能退化和心衰的发生发展提供参考。方法回顾性分析厦门大学附属东南医院2006年2月至2016年7月经超声心动图及胸片诊断为镜像右位心且不合并其他异常畸形的老年患者12例(其中男7例,女5例)临床资料,与12例老年正常心志愿者对比分析左心室射血分数(EF)、左心室缩短分数(FS)、心率(HR)、每搏输出量(SV)、每分输出量(CO)等心功能指标,比较两者间是否存在明显差异。结果镜像右位心老年患者的心率、左室射血分数、左心室缩短分数、每搏输出量、每分输出量分别为(83±12.79)次/min、(0.61±0.58)、(0.32±0.40)、(57.82±11.90)mL和(4.84±1.42)L/min,正常老年人分别为(71.71±11.92)次/min、(0.61±0.57)、(0.32±0.46)、(58.71±11.78)mL和(4.22±1.22)L/min。2组人群比较,心率差异有统计学意义(P<0.05),而左室射血分数、左心室缩短分数、每搏输出量、每分输出量差异无统计学意(P>0.05)。结论镜像右位心老年患者的心率比正常老年人心率快,而其他心功能指标则无明显区别。ObjectiveBy comparing the differences of heart function between the mirror-image dextrocardia elderly and the normal elderly in the resting state,to provide a reference for the development of heart failure and heart failure in the elderly mirror-image dextrocardia patients MethodsWe collect separately12diagnosed with mirror-image dextrocardia elderly(including7males and5females)by echocardiography and chest radiographs and12normal elderly in the southeast hospital of Xiamen University from February2006to July2016,compared and analyzed cardiac function indicators as follows:Left ventricular ejection fraction(EF),left ventricular shortening score(FS),heart rate(HR),stroke volume(SV),and output per minute(CO),and to determine whether there is a difference between the two elderly.ResultsThe right heart rate,left ventricular ejection fraction,left ventricular shortening score,stroke volume,and per minute output of the mirror-image dextrocardia elderly are(83±12.79)t/min,(0.61±0.58),(0.32±0.40),(57.82±11.90)mL,and(4.84±1.42)L/min,respectively.And the normal elderly are(71.71±11.92)t/min,(0.61±0.57),(0.32±0.46),(58.71±11.78)mL,and(4.22±1.22)L/min,respectively.There are significant differences in heart function between the two groups(P<0.05),but there are no significant difference between the left ventricular ejection fraction,the left ventricular shortening score and the stroke volume per stroke(P>0.05).ConclusionThe heart rate of the elderly patients with mirror-image dextrocardia is faster than the normal elderly,and the cardiac function index of the left ventricular ejection fraction,left ventricular shortening score,stroke volume are no obvious difference.
