目的:探讨超声参数在诊断慢性心力衰竭患者疾病方面的价值。方法:对安岳县中医医院收治的72例慢性心力衰竭患者采用GE LOGIQ S8型超声仪,检测过程中记录患者室间隔厚度(IVS)、左室后壁厚度(LVPW)、左房内径(LAD)、射血分数(EF)、二尖瓣口舒张早期最大血流速度(E峰)和舒张晚期最大血流速度(A峰)等,并测定血浆B型脑利钠肽前体(NT-Pro BNP)水平。结果:不同心功能组患者在心力衰竭超声指数方面比较,差异具有统计学意义(P<0.05),并且患者心力衰竭超声指数与心功能分级具有正相关性。超声所反映的收缩与舒张功能的各项参数与血浆NT-Pro BNP显著相关,D/S、E值、EF值、左房内径、肺动脉压力及瓣膜反流程度等与血浆NT-Pro BNP水平的相关性较大(P<0.05)。结论:心脏超声诊断参数能全面可靠的反映患者的心脏功能。
Objective: To investigate the value of ultrasound parameters in the diagnosis of disease in patients with chronic heart failure. Methods: Seventy-two patients with chronic heart failure admitted to Anyue County Chinese Medicine Hospital were enrolled in this study. GE LOGIQ S8 type ultrasound system was used to record the interventricular septum thickness (IVS), left ventricular posterior wall thickness (LVPW), left atrium inner diameter ), Ejection fraction (EF), peak early diastolic velocity (E peak) and late diastolic peak velocity (A peak) of mitral valve were measured, and the levels of plasma brain natriuretic peptide precursor (NT- Pro BNP) levels. Results: There was a significant difference between the patients with different cardiac function groups in the heart failure index (P <0.05), and there was a positive correlation between the heart failure index and the heart function in patients with heart failure. The parameters of systolic and diastolic function reflected by ultrasound were significantly correlated with plasma NT-Pro BNP, D / S, E, EF, left atrial diameter, pulmonary artery pressure and valve regurgitation and plasma NT-Pro BNP levels The correlation was significant (P <0.05). Conclusion: The diagnostic parameters of cardiac ultrasound can comprehensively and reliably reflect the cardiac function of patients.
