[摘要]目的 分析和探討无创血流动力学检测在慢性心力衰竭（CHF）患者临床诊疗中的应用效果。方法 选取2018年6月～2019年10月我院收治的106例CHF患者作为研究对象，按照硬币法将其分为对照组（53例）与研究组（53例）。对照组患者采用常规观察方法，研究组采用无创血流动力学指标检测方法。比较两组患者的临床事件发生情况、住院天数以及出院时的各项心功能指标水平。结果 研究组患者的急性心力衰竭发生率和心源性死亡发生率均低于对照组，差异有统计学意义（P<0.05）;研究组患者的住院时间为（14.72±6.14）d，短于对照组的（18.85±8.24）d，差异有统计学意义（P<0.05）;出院时，研究组患者的左室射血分数（LVEF）水平高于对照组，脑钠肽（BNP）水平低于对照组，6 min步行距离长于对照组，差异有统计学意义（P<0.05）。结论 在CHF患者住院治疗过程中，为其实施无创血流动力学检测，能对各项治疗药物的应用起到良好的指导作用，进而有效降低患者所面临的急性心力衰竭发生风险，改善其心功能，缩短其住院时间。

[Abstract] Objective To analyze and discuss the application effect of non-invasive hemodynamic test in the clinical diagnosis and treatment of patients with chronic heart failure （CHF）. Methods A total of 106 patients with CHF admitted to our hospital from June 2018 to October 2019 were selected as the research objects. According to the coin method， they were divided into the control group （53 cases） and the research group （53 cases）. The control group adopted the conventional observation method， and the research group adopted the non-invasive hemodynamic index detection method. The clinical events， length of stay and cardiac function indexes were compared between the two groups. Results The incidence rates of acute heart failure and cardiac death in the study group were lower than those in the control group， with statistically significant differences （P<0.05）. The length of stay in the study group was （14.72±6.14） d， which was shorter than that in the control group （18.85±8.24） d， and the difference was statistically significant （P<0.05）. At the time of discharge， the left ventricular ejection fraction （LVEF） level of patients in the study group was higher than that of the control group， the level of brain natriuretic peptide （BNP） was lower than that of the control group， and the walking distance of 6 min was longer than that of the control group， the differences were statistically significant （P<0.05）. Conclusion In the process of inpatient treatment of CHF patients， non-invasive hemodynamic test can play a good role in guiding the application of various treatment drugs， thus effectively reducing the risk of acute heart failure faced by patients， improving their heart function， and shorten their hospitalization time.

以往，临床常通过实施以肺动脉导管为基础的血流动力学监测来达到降低慢性心力衰竭（CHF）患者再入院率的目的，但此种血流动力学监测手段，不仅具有一定的创伤性，而且患者所面临的并发症发生风险也较高，使之在临床范围内的应用受到了一定限制。胸腔阻抗法血流动力学检测仪具有可重复性高、操作简便、测量准确、能实现实时测量等诸多优点，是一种近些年来出现在临床范围内的无创血流动力学状态评估方法。相关研究结果指出，在CHF患者住院治疗过程中，为其实施无创血流动力学监测，能有效指导CHF患者的临床用药，在提升治疗效果的同时，改善患者的疾病预后[1-2]。本研究选取我院收治的106例CHF患者作为研究对象，旨在对无创血流动力学检测在CHF临床诊疗中所起到的指导作用展开分析与探讨，现报道如下。……
