摘要
目的 分析 48例小心脏患者的左室收缩功能各项参数及其临床诊断 ,提出小心脏综合征 (SHS)的修订诊断标准 ,并了解其并发症情况。方法 收集 48例超声心动图提示心脏形态结构正常 ,而左室舒张末内径 (LVDd) <41mm的小心脏患者 ,测量其左室收缩功能各参数 ,与正常组比较 ,并进行统计分析。结果 本组小心脏患者的左室舒张末内径指数 (LVDI)、每搏输出量 (SV)、每搏指数 (SI)、心输出量 (CO)、心脏指数 (CI)与正常组对照显著减少 ,3 1%的小心脏患者合并冠心病 ,且年龄大于 40岁。结论 1.LDVd <41mm、LVDI <2 5mm m2 ,且同时具备以下条件之一者 :①SV<3 9ml;②SI <2 6ml m2 ;③CO <2 .4L min ;④CI<1.6L min·m2 ,可拟作小心脏综合征的超声诊断标准。 2 .年龄大于 40岁的小心脏患者有合并冠心病的可能。
Objective Analyzed the parameters of left ventricular systolic function and clinical diagnosis in 48 small heart patients,put forward the revisional Echocardiographic criteria of small heart syndrome and realized its complications. Methods Collected 48 small heart patients whose heart structure were normal and the left ventricular end-diastolic internal dimension were less than 41 mm,and compared their left ventricular systolic functional parameter with the normal heart group.Results The left ventricular end-diastolic internal dimension index(LVDI),stroke-volume(SV),stroke-index(SI),cardiac-output(CO),cardiac index(CI) of small heart group were less than that of normal group.31% of the patients of small heart complicated with coronary heart disease and their age are all above 40 years.Conclusion 1.The revisional Echocardiographic criteria of small heart syndrome were suggestted as:LVDd<41 mm、LVDI<2.5 cm/m 2 in small heart patient and accompanied by one or more as follows:①SV<39 ml;②SI<26 ml/m 2;③CO< 2.4 L/min; ④CI<1.6 L/min·m 2. 2.Coronary heart disease wight be complicated in the small heart patient whose age is above 40 years old.
