Analysis of the effect and accuracy of cardiac color Doppler ultrasound in the diagnosis of hypertensive heart disease
心脏彩色多普勒超声在高血压性心脏病诊断的效果及准确性分析

摘要

目的 探究高血压性心脏病诊断中心脏彩色多普勒超声的诊断效果及准确性。方法 选择本院（2021年1月至2022年12月）收治的高血压性心脏病患者50例作为研究对象（纳入观察组）；并选择本院同期内开展体检的健康人士50例作为参照对象（纳入对照组）。两组对象均接受心脏彩色多普勒超声诊断，比较两组对象超声参数。同时，观察组对象于心脏超声基础上还开展心电图检查，比较心脏超声与心电图诊断疾病的准确性。结果 观察组E/V值（1.43±0.25）、左心房内径/主动脉根内径值（1.35±0.20）、左心房内径值（4.09±0.45）cm、舒张末期容积（115.34±10.17）mL，均较对照组高（T=3.6097；T=7.2411；T=11.0391；T=7.8798；P<0.05）。超声检查主动脉弹性减退率10.00%、主动脉扩张率8.00%、左心室肥厚率46.00%、左心房增大率40.00%，均较心电图高（χ2=5.2632；χ2=4.1667；χ2=6.4171；χ2=4.7619；P<0.05）。结论 高血压心脏病诊断中，心脏彩色多普勒超声诊断效果良好，诊断准确性高，建议首选。

Abstract

Objective To explore the diagnostic effect and accuracy of cardiac color Doppler ultrasound in the diagnosis of hypertensive heart disease.
Methods 50 patients with hypertensive heart disease admitted to our hospital (January 2021 to December 2022) were selected as the study subjects (included in the observation group); and 50 healthy patients who carried out physical examination during the same period were selected as the reference subjects (included in the control group). Both groups of subjects received cardiac color Doppler ultrasound diagnosis to compare ultrasound parameters between the two groups. At the same time, the observation group subjects also carried out electrocardiogram examination on the basis of cardiac ultrasound to compare the accuracy of disease diagnosis between cardiac ultrasound and electrocardiogram.
Results E / V (1.43 ± 0.25), left atrial diameter / aortic diameter (1.35 ± 0.20), left atrial diameter (4.09 ± 0.45) cm, and end-diastolic volume (115.34 ± 10.17) mL in the observation group, were higher than those in the control group (T=3.6097; T=7.2411; T=11.0391; T=7.8798; P <0.05). The aortic elasticity rate 10.00%, aortic expansion rate 8.00%, left ventricular hypertrophy rate 46.00% and left atrial enlargement rate 40.00%, which were higher than ECG (χ2=5.2632; χ2=4.1667; χ2=6.4171; χ2=4.7619; P <0.05).
Conclusion   In the diagnosis of hypertensive heart disease, cardiac color Doppler ultrasound has good diagnostic effect, and high diagnostic accuracy, recommended preferred.
