摘要:
目的 探讨经胸多普勒超声心动图半定量评估左室舒张末压 (L VEDP,EDP)的有效指标。方法 对 88例患者由左心导管介入性检测 L VEDP,经胸多普勒超声心动图记录二尖瓣及肺静脉血流参数。以 EDP实测值作为金标准 ,进行无创与有创性检测的对比研究。结果 直线相关分析显示 ,肺静脉 A波与二尖瓣 A波时限差值 (PAd- Ad)与 EDP相关最佳 (r=0 .73,P<0 .0 1) ;肺静脉 A波时限等于或超过二尖瓣 A波时限 (即 PAd- Ad≥ 0 )估测 EDP≥15 m m Hg(1mm Hg=0 .133k Pa)的敏感性为 85 .1% ,特异性为 90 .2 % ,阳性预测值为 90 .9% ,阴性预测值为84.1%。结论 由多普勒超声心动图血流参数 PAd- Ad≥ 0可作为临床判断 L VEDP≥ 15 mm Hg的一项简便而可靠的半定量指标。
Abstract:
AIM This study was conducted to explore the useful index of semi quantitative estimating left ventricular end diastolic pressure(LVEDP,EDP) with transthoracic ultrasound. METHODS Invasive EDP was measured through a fluid filled pig tail catheter in 88 patients. Noninvasive pulmonary venous and mitral flow variables were recorded by Doppler ultrasound. RESULTS Linear regression analysis showed the difference in duration between the pulmonary venous A and mitral A wave (PAd-Ad) had the best correlation with EDP ( r=0.73, P<0.01) ;The duration of the pulonary venous A wave equalling or exceeding the duration of the mitral A wave (that means PAd-Ad≥0) predicted EDP≥15 mmHg with a sensitivity of 85. 1%; a specificity of 90. 2%; a positive predictive value of 90. 9% and a negative preductive value of 84. 1%. CONCLUSION PAd-Ad≥0 may provide a semi-quantitative index for estimating LVEDP ≥15 mmHg.
