无创心脏血流动力学监测仪与超声心动图检测心功能指标的相关性分析

目的探讨CHMT3002心脏无创血流动力学监测仪评价临床患者心功能的可能性。方法选择上海市中山医院住院病人26例．其中心功能不全组11例，心功能1级对照组15例。在对每一例研究对象行超声心动图检查后立即行无创心脏血流动力学检测。采用线性相关分析及Bland-Altman一致性分析方法对两者进行相关性及一致性分析。结果两种仪器对LVEF、SV、SVI、CO、CI、EDV、LVET及PEP／LVET等指标的检测数值具有线性相关关系，而对PEP的检测数值无明显相关性。其中，两种方法在检测LVEF、LVET指标方面具有较好一致性，在SV、SVI、CO、CI、EDV方面的一致性一般．而对PEP、PEP／LVET检测的一致性则较差。结论CHMT3002心脏血流动力学监测仪的检测尚能较真实地反映患者心脏功能情况，但其并不能替代超声心动图对心功能的评价。

Analysis of the Correlation between Non-invasive Hemodynamic Monitor and Cardiac Echocardiography on tne Evaluation of Cardiac Function

Objective To explore the possibility of clinical evaluation of cardiac function by CHM T3002 non-invasive hemodynamic monitor. Methods A total of 26 pateints admitted to Zhongshan Hospital in Shanghai were enrolled, including 11 cardiac insufficiency patients and 15 control. Each subject was tested by non-invasive cardiac hemodynamic monitor immediately after echocardiography. Linear regression analysis and Bland-Altman consistency analysis were used in the analysis of relevance and consistency between two different methods. Results Linear correlation was shown on LVEF, SV, SVI, CO, CI, EDV, LVET and PEP/LVET, but not on PEP, between the two methods. Moreover, the consistency of the two methods was highly confirmed on LVEF and LVET, less on SV, SVI, CO, CI and EDV, while awfully weak on PEP and PEP/LVET. Conclusion CHM T3002 non-invasive hemodynamic monitor may be useful in assessing patients＇ cardiac function, however, it can not replace cardiac echocardiography.
