高血压左室肥厚伴左心力衰竭行心脏超声检查价值分析

Value of Echocardiography in Patients with Left Ventricular Hypertrophy and Left Heart Failure

目的分析高血压左室肥厚伴左心力衰竭行心脏超声检查价值。方法研究时段自2017年11月—2018年11月,方便选定该院收治的60例高血压左室肥厚伴左心力衰竭患者作为研究组,以及同期门诊体检的60名健康人员作为对照组,均行心脏超声检查,对比两组心脏超声检查结果,其次对比心功能Ⅰ级、Ⅱ级、Ⅲ级患者心脏超声检查结果。结果研究组早期峰值流速/舒张晚期峰值流速、左房内径、左室舒张末期内径、左室射血分数分别是(12.86±2.25)%、(43.66±5.17)mm、(56.89±8.28)mm、(50.26±4.25)%;对照组分别是(6.52±0.68)%、(27.12±3.05)mm、(42.52±4.05)mm、(71.25±8.66)%。研究组早期峰值流速/舒张晚期峰值流速、左房内径、左室舒张末期内径显著较对照组高,左室射血分数显著较对照组低(t=20.8931、21.3437、12.0760、16.8543,P<0.05)。心功能Ⅰ级组早期峰值流速/舒张晚期峰值流速、左房内径、左室舒张末期内径、左室射血分数分别是(10.52±2.14)%、(42.25±6.25)mm、(47.26±6.25)mm、(60.25±5.14)%;心功能Ⅱ级组分别是(12.86±2.62)%、(51.05±8.62)mm、(53.92±8.14)mm、(52.15±3.05)%;心功能Ⅲ级组分别是(18.66±3.66)%、(60.92±10.14)mm、(70.26±11.28)mm、(46.05±1.05)%。早期峰值流速/舒张晚期峰值流速、左房内径、左室舒张末期内径:心功能Ⅰ级<心功能Ⅱ级<心功能Ⅲ级;左室射血分数:心功能I级>心功能Ⅱ级>心功能Ⅲ级(t=6.2514、9.3671、8.1411、10.0176,P<0.05)。结论心脏超声在诊断高血压左室肥厚伴左心力衰竭中具有较高的诊断价值,可对不同心功能患者病情做出分析,对于临床方案的制定具有重要的指导意义,值得借鉴。

Objective To analyze the value of echocardiography in patients with left ventricular hypertrophy and left heart failure. Methods From November 2017 to November 2018, 60 patients with hypertensive left ventricular hypertrophy and left heart failure admitted to our hospital were conveniently selected as the study group, and 60 healthy subjects from the outpatient clinic were used as the control group. All patients underwent echocardiography, comparing the results of echocardiography between the two groups, and then comparing the results of echocardiography in patients with grade Ⅰ,Ⅱ, and Ⅲ cardiac function. Results The early peak flow rate/peak diastolic peak flow rate, left atrial diameter, left ventricular end diastolic diameter, and left ventricular ejection fraction were (12.86±2.25)%,(43.66±5.17) mm,(56.89±8.28) mm,(50.26±4.25)%;the control group was (6.52±0.68)%,(27.12±3.05) mm,(42.52±4.05) mm,(71.25±8.66)%, respectively. The peak flow velocity/left diastolic peak flow velocity, left atrial diameter, and left ventricular end diastolic diameter were significantly higher in the study group than in the control group. The left ventricular ejection fraction was significantly lower than the control group(t=20.893 1, 21.343 7, 12.076 0, 16.854 3;P<0.05). Early peak flow velocity/late peak diastolic velocity, left atrial diameter, left ventricular end-diastolic diameter, and left ventricular ejection fraction were (10.52±2.14)%,(42.25±6.25) mm,(47.26±6.25) mm,(60.25±5.14)%;cardiac function Ⅱ group were (12.86±2.62)%,(51.05±8.62) mm,(53.92 ± 8.14) mm,(52.15 ± 3.05)%;cardiac function Ⅲ group of (18.66±3.66)%,(60.92±10.14) mm,(70.26±11.28) mm,(46.05±1.05)%. Early peak flow rate / late diastolic peak flow rate, left atrial diameter, left ventricular end diastolic diameter: cardiac function grade Ⅰ<cardiac function grade Ⅱ<cardiac function grade Ⅲ;left ventricular ejection fraction: cardiac function grade Ⅰ> cardiac function grade Ⅱ> Cardiac function grade Ⅲ(t=6.251 4, 9.367 1, 8.141 1, 10.017 6, P<0.01). Conclusion Cardiac ultrasound has a high diagnostic value in the diagnosis of hypertensive left ventricular hypertrophy with left heart failure. It can analyze the condition of patients with different cardiac functions and has important guiding significance for the formulation of clinical programs. It is worth learning.
