目的探讨应用多普勒和Tei指数对糖尿病性心肌病患者和高血压心脏病患者的左心功能进行对比研究。方法将接受检验的患者分为糖尿病性心肌病组、高血压心脏病组和对照组(健康志愿者),分别对三组患者进行常规心动图检测、Tei指数检测以及DTI检测,测定出Sa值、Ea值、Aa值等。结果糖尿病性心肌病组以及高血压心脏病组的Tei指数高于对照组,差异具有统计学意义(P<0.05),糖尿病性心肌病组的tei指数高于高血压心脏病组,差异具有统计学意义(P<0.05)。对照组及高血压心脏病组的最高射血速度显著低于糖尿病性心肌病组,差异具有统计学意义。结论糖尿病性心肌病与高血压心脏病均能造成心肌性能衰退,而糖尿病性心肌病对心肌收缩功能的影响较大。
Objective To investigate the application of Doppler and Tei index in the comparison of left ventricular function in patients with diabetic cardiomyopathy and hypertensive heart disease. Methods The patients were divided into diabetic cardiomyopathy group, hypertensive heart disease group and control group (healthy volunteers). The three groups of patients were examined by routine cardiogram, Tei index and DTI, and the Sa value , Ea value, Aa value and the like. Results Tei index in diabetic cardiomyopathy group and hypertensive heart disease group was higher than that in control group, the difference was statistically significant (P <0.05), tei index in diabetic cardiomyopathy group was higher than that in hypertensive heart disease group, the difference was statistically significant Significance (P <0.05). The highest ejection velocity in control group and hypertensive heart disease group was significantly lower than that in diabetic cardiomyopathy group, the difference was statistically significant. Conclusions Both diabetic cardiomyopathy and hypertensive heart disease can cause the decline of myocardial performance, while diabetic cardiomyopathy has a great influence on myocardial contractile function.
