摘要
目的:探讨超声心动图房室平面位移(AVPD)法评价高血压病早期患者(HT)左室舒张功能的可行性。方法:分别记录200例HT患者左房射血所致AVPD(AVPDa)值、AVPD与二尖瓣环4个位点上的AVPD均值(AVPDmean)比值,并与二尖瓣口E/A比值法(E/A分析法)进行对比。结果:200例HT患者AVPD法测值:AVPDmean值为(0·66±0·15)cm,AVPDa为(0·79±0·46)cm,E/A分析法:E/A最大峰值速度分别为(75·38±11·66)cm/s,(82·36±16·82)cm/s。根据AVPD方法诊断163例舒张功能异常,E/A分析法诊断171例舒张功能异常,二者之间差异无显著性意义(χ2=1·78,P>0·05)。结论:AVPD方法与E/A分析法有较好符合性,为一无创性评价HT患者左室舒张功能的新方法。
Objective:To assess the feasibility and reliability of echocardiography of atrioventricular plane displacement (AVPD) in predicting left ventricular diastolic function (LVDF ).Methods:In 200 hypertension patients (HT), the parameters of AVPDa,AVPDa/AVPD mean (mean value of AVPD) and the ratio depicted above and mitral E/A were detected and compared by pulsed Doppler.Results:The parameters of AVPDa, AVPDmean, E and A were (0.66 ±0.15)cm,(0.79±0.46)cm,(75.38 ±11.66)cm/s;(82.36±16.82)cm/s respectively, there are 163 patients accompanied by LVDF according to the AVPD. On the other hand, there were 171 patients by E/A method.There is no significant differece between the two methods.Conclusion:The AVPD studied for assessing the LVDF in HT is a new non-damage way.
