目的:探讨超声心动图对老年冠心病左室舒张末压进行评估的效果.方法:将我院2008年11月至2011年8月我院收治的76例冠心病患者,先进行超声心动图检查测量出患者舒张早期二尖瓣血流速度E波与多普勒组织成像舒张早期二尖瓣环速度比值(E/E')估计左室舒张末压,作为实验组数据;然后进行传统的左心导管测定左室舒张末压LVEDP,作为对照组数据.进行实验组超声指标与对照组LVEDP的相关性分析,并比较两组检查后的创伤率.结果:实验组的E/E'与对照组的LVEDP呈高度正相关(其中,r=0.8214,P=0.0002),回归方程显示LVEDP每升高1mmHG,E/E'平均升高0.4196;实验组检查后,创伤率为0,而进行左心导管测定后,及对照组的创伤率为3.75%,差异明显,P<0.05,结果具有统计学意义.结论:通过超声心动图来评估老年冠心病患者的左室舒张末压,结果准确,并能有效防止创伤,价格低廉,值得在临床中推广.%Objective: To explore the echocardiography in assessment of left ventricular end diastolic pressure the effect on elderly coronary heart disease . Method: 76 patients with coronary artery disease in our hospital from Nov. 2008 to Aug. 2011 were selected. By the echocardiography to measure the patients blood flow velocity of early diastolic mitral E-wave doppler tissue imaging early diastolic mitral annular velocity ratio ( E / E " ), then estimated the left ventricular end diastolic pressure as the experimental group data. Then use the traditional left-heart catheter to determine left ventricular end diastolic pressure LVEDP as control group data. Correlation analysis of ultrasound indicators of the experimental group and control group's LVEDP , and compared both groups trauma rate after inspection. Result: Experimental group E / E 'and the LVEDP in control group was highly positive correlation ( r = 0. 8214, P = 0. 0002 ), regression equations showed LVEDP increased 1 mmHG, the E / E' increased by an average of 0. 4196 , examination of the experimental group, trauma was O, while the determination of left heart catheterization, the control group of trauma was 3. 75% , the differences are significant, P<0. 05 , There's statistically significant. Conclusion: By echocardiography assessing left ventricular diastolic pressure in elderly patients with coronary artery disease, the results are accurate, which can effectively prevent the trauma, with low price, it's worthy of promotion in the clinical practice.
