心脏彩色多普勒超声与心电图在高血压性心脏病诊断中的应用

摘要

目的 探讨心脏彩色多普勒超声与心电图在高血压性心脏病诊断中的应用。方法 选取2022年1月-2023年1月本院接收的70例高血压性心脏病患者作为研究对象，其中左室后壁增厚32例、中室间隔增厚45例、左室舒张功能减退66例、左室收缩功能减退31例、左房扩大19例、左室扩大15例、主动脉增宽28例，均对其进行心脏彩色多普勒超声检查、心电图检查、联合检查，分析三种检查方式的诊断效果。结果 联合检查对左室后壁增厚、中室间隔增厚、左室舒张功能减退、左室收缩功能减退、左房扩大、左室扩大、主动脉增宽的检出率分别为93.75%、97.78%、98.48%、93.55%、100.00%、100.00%、96.43%，均高于心脏彩色超声检查的84.38%、88.89%、89.39%、83.87%、84.21%、93.33%、89.29%与心电图检查的78.13%、80.00%、77.27%、74.19%、68.42%、73.33%、78.57%（P＜0.05）；相较于单一检查，联合检查检出射血分数、左房内径、左房/主动脉内径值较高，检出E/A值较低（P＜0.05）。结论 将心脏彩色多普勒超声与心电图联合运用于高血压性心脏病的诊断中，能够在一定程度上提高检出率，同时有利于对患者各项心脏指标的判断，为患者治疗方案的制定提供有力依据。

Abstract

Objective To investigate the application of cardiac color Doppler ultrasound and electrocardiogram in the diagnosis of hypertensive heart disease.
Methods A total of 70 patients with hypertensive heart disease admitted to our hospital from January 2022 to January 2023 were selected as the study objects, including 32 cases of left ventricular posterior wall thickening, 45 cases of middle ventricular septal thickening, 66 cases of left ventricular diastolic dysfunction, 31 cases of left ventricular systolic dysfunction, 19 cases of left atrial enlargement, 15 cases of left ventricular enlargement, and 28 cases of aortic widening. Cardiac color Doppler ultrasonography, electrocardiogram and combined examination were performed to analyze the diagnostic effect of the three examination methods.
Results The detection rate of the LV posterior wall thickening, middle ventricular septal thickening, left ventricular diastolic dysfunction, left ventricular enlargement, left ventricular enlargement and aortic enlargement were 93.75%, 97.78%, 98.48%, 93.55%, 100.00%, 100.00%, 96.43%, respectively, These were higher than 84.38%, 88.89%, 89.39%, 83.87%, 84.21%, 93.33%, 89.29% and 78.13%, 80.00%, 77.27%, 74.19%, 68.42%, 73.33%, 78.57% (P <0.05); Compared to a single examination, combined examination detected higher ejection fraction, left atrial internal diameter, left atrial / aortic internal diameter value, low E / A value was detected (P <0.05).
Conclusion   The combination of cardiac color Doppler ultrasound and electrocardiogram in the diagnosis of hypertensive heart disease can improve the detection rate to a certain extent, and be conducive to the judgment of patients 'various cardiac indicators, and provide a strong basis for the formulation of patients' treatment plan.
