心脏彩超对慢性心衰的心脏结构与血液流速及波动速度状态的鉴别诊断

Differential Diagnosis of Cardiac Structure,Blood Flow Velocity,and Fluctuation Velocity Status of Chronic Heart Failure with Cardiac Ultrasound

目的分析心脏彩超对慢性心力衰竭患者心脏结构、血流速度及波动速度状况的鉴别诊断效果。方法将本院2022年1月-2023年6月治疗的90例慢性心衰患者(视为观察组)临床诊疗资料进行回顾性分析,按照左室射血分数分为正常组(n=23例)、下降组(n=67例);选取同期来院体检者视为对照组(n=90例),均实施心脏彩超检查,分析其临床鉴别诊断效能。结果与对照组相比,观察组LVEF较低,但是LVEDD、LAD较高,组间差异有统计学意义(P<0.05)。正常组LVEF表达水平低于下降组,但LVEDD、LAD表达水平均高于对照组,组间差异有统计学意义(P<0.05)。Ⅲ级、Ⅳ级患者LVEF表达水平低于Ⅰ级、Ⅱ级,组间差异有统计学意义(P<0.05)。结论心脏彩超检查可以清楚直观地体现慢性心衰患者心脏组织、血流速度与波动速度,能为临床医师鉴别区分疾病、制定个性化诊疗方式提供一定参考依据。

Objective To explore and analyze differential diagnostic effect of cardiac color Doppler ultrasound on cardiac structure,blood flow velocity,and fluctuation velocity of patients with chronic heart failure.Methods The paper reviewed and analyzed clinical diagnosis and treatment data of 90 patients with chronic heart failure(observation group)in our hospital from January 2022 to June 2023,and divided them into normal group(n=23 cases)and decreased group(n=67 cases)according to left ventricular ejection fraction;chose patients with physical examination during the same period as control group(n=90 cases),Clinical differential diagnosis effect was explored based on cardiac ultrasound.Results Observation group(chronic heart failure patients)had lower LVEF,but higher LVEDD and LAD than control group(healthy examinees),(P<0.05).Expression level of LVEF in normal group was lower than decreased group,expression levels of LVEDD and LAD were higher than control group(P<0.05).Expression level of LVEF in gradeⅢandⅣpatients was lower than grade Ⅰ andⅡpatients(P<0.05).Conclusion Cardiac ultrasound can reflect heart tissue,blood flow velocity,and fluctuation velocity of patients with chronic heart failure clearly and intuitively,can provide some certain reference basis for clinical physicians to distinguish diseases and develop personalized diagnosis and treatment methods.
