摘要
对经冠造确诊的22例冠心病患者(A组)及21例非冠心病患者(B组)左室舒张未压(LVEDP)与PtfV_1进行了检测。结果显示,A组LVEDP总的异常率为81.9%,Ptfv_1总的异常率为77.2%。B组LVEDP总的异常率为23.8%,Ptfv_1总的异常率为38.1%。A组Ptfv_1异常检出率明显高于B组,差异非常显著(P<0.01)。提示:冠心病LVEDP增高可引起Ptfv_1的异常变化。由于两者具有良好的相关性(r=0.53,P<0.01),故利用PtfV_1可间接了解LVEDP的变化,为Ptfv_1判断左室功能变化及左房负荷中的应用提供了依据。
According to the results ob-tained ftom
coronary angiography in 43 parients ,among whom 22 were,preved to have CHD groupA, the
evidences of CHDwere avoided 21patients(group B or con-trol groupl ).The relationship
betweenLVEDP and Ptfv_1 of both groups assaged. The results showed that the rate ofLVEDP
abnormality in group A was 81. 9%and ptfv_1 was 77.2% respectiely. Butin group B the aboue
mentioned rates wereonly 23.8%and 38.1%accordingly.Itshowed that rates of abnormalty
bothLVEDP and ptfv_1 group A were signif-cantly highder than that in gtoup B(P<0. 01).thus ,It is
suggested that increaseof LVEDP may be one of the causes whichaffected the value of ptf.
Moreover,the Pt-fv_1 and LVEDP showed close correlationaparantly(r-0.53,P<0.01).Thus
,thechanges of Ptfv_1 may be used to mirror thechanges of LVEDP indirectly and toevaluate the
LV function along mith LAload.
