目的:评估生物阻抗法心排血量监测在心肌梗死合并心衰患者中的临床应用价值。方法:急性心肌梗死合并心力衰竭患者17例,应用生物阻抗法和温度稀释法(TD)同时测定心排血量(CO)及其他相关参数,对两种方法所测数据进行自体配对相关性分析。结果:配对t检验显示两种方法测定的CO值差异无统计学意义(P>0.05),相关分析示相关系数为0.90,阻抗法和温度稀释法测定心排血量有较好的相关性。结论:生物阻抗法是一种无创、简便、连续的测定心输出量的方法,能较客观地反映心功能状况,具有一定的临床价值。
OBJECTIVE: To evaluate the clinical value of bioimpedance cardiac output monitoring in patients with myocardial infarction complicated by heart failure. Methods: A total of 17 patients with acute myocardial infarction complicated with heart failure were enrolled in this study. The cardiac output (CO) and other relevant parameters were measured simultaneously by bioimpedance and temperature-thinning (TD) methods. . Results: The paired t-test showed that there was no significant difference in the CO values measured by the two methods (P> 0.05). Correlation analysis showed that the correlation coefficient was 0.90. There was a good correlation between the impedance method and the temperature dilution method for the determination of cardiac output. Conclusion: Bioimpedance method is a noninvasive, simple and continuous method for the determination of cardiac output, which can objectively reflect the status of cardiac function and has certain clinical value.
