心脏彩超诊断高血压左室肥厚伴左心力衰竭的价值

Value of color Doppler echocardiography in diagnosis of hypertensive left ventricular hypertrophy with left heart failure

目的:研究分析心脏彩超诊断高血压左室肥厚伴左心力衰竭的临床价值。方法:将本院2015年4月—2017年5月间收治的高血压左室肥厚伴左心力衰竭患者作为此次研究病例的选择范围,将40例符合此次研究纳入标准并知情同意的患者作为研究观察组,另选40例同期于本院接受健康体检者作为本次研究的对照组。两组参与者均接受心脏彩超检查,并对检查结果进行对比分析。结果:对比左室舒张末期内径、左室收缩末期内径、左室射血分数、E/A值,显示组间差异显著(P>0.05)。对比不同心功能分级患者的心脏彩超检查结果,也提示随着心功能分级的提高,左室射血分数会逐渐降低、左室舒张末期内径、左室收缩末期内径以及E/A值水平则均明显上升(P<0.05)。结论:对高血压左室肥厚伴左心力衰竭患者实施心脏彩超检查可在极大程度上了解患者心脏指标变化情况,为临床诊断及治疗提供有效依据,临床应用价值显著。

Objective To study and analyze the clinical value of color Doppler echocardiography in the diagnosis of hypertensive left ventricular hypertrophy with left heart failure. Patients with hypertensive left ventricular hypertrophy with left heart failure admitted from April 2015 to May 2017 were selected for this study. Forty patients who met the criteria included in the study and had informed consent were used as the study observation group. Another 40 healthy persons were selected as the control group in this study. The two groups were examined by echocardiography and the results were compared. Results The left ventricular enddiastolic diameter was compared. Left ventricular end-systolic diameter The E/A value of ventricular ejection fraction showed significant difference between the groups(P>0.05). The results of echocardiography in patients with different cardiac function grade also indicated that the cardiac function grade increased with the increase of cardiac function grade. Left ventricular ejection fraction decreased gradually and left ventricular end-diastolic diameter decreased. Left ventricular end-systolic diameter and E/A level increased significantly(P<0.05). Conclusion The changes of cardiac indexes in patients with hypertension and left ventricular hypertrophy with left heart failure can be greatly understood by color Doppler echocardiography. To provide effective basis for clinical diagnosis and treatment, clinical application value is significant.
