【摘要】 目的 分析胸阻抗法（TEB）无创血流动力学监测仪用于射血分数保留型心力衰竭（HFpEF）的诊断价值。方法 选取2023年1月至2024年12月我院收治的HFpEF患者76例作为HFpEF组，另选择同时期于我院体检的健康者76例作为健康组。两组均进行TEB无创血流动力学监测仪检查，比较两组的心脏泵血功能[心脏指数（CI）、心搏指数（SI）、心搏出量（SV）]、每搏外周阻力（SSVR）、胸液传导性（TFC）、收缩时间比（STR）及左心功能[左心室每搏做功（LSW）、左心室每搏做功指数（LSWI）、左心室射血时间（LVET）]。结果 HFpEF组CI、 SI、 SV水平明显低于健康组（P<0.05）; HFpEF组SSVR、 TFC、 STR水平明显高于健康组（P<0.05）；两组的LSW、 LSWI、 LVET水平对比无统计学差异（P >0.05）。结论 TEB无创血流动力学监测仪用于HFpEF诊断中，能够监测患者的心脏泵血功能、左心功能及血管阻力指数，有利于早期诊断HFpEF，并分析患者病情，辅助临床开展针对性治疗。更多还原

【Abstract】 Objective To analyze the diagnostic value of thoracic electrical bioimpedance(TEB) non-invasive hemodynamic monitor for heart failure with preserved ejection fraction(HFpEF). Methods 76 HFpEF patients admitted to our hospital from January 2023to December 2024 were selected as the HFpEF group, and another 76 healthy subjects who underwent physical examination in our hospital during the same period were selected as the healthy group. Both groups were examined by TEB noninvasive hemodynamic monitor. The heart pumping function [cardiac index(CI), stroke index(SI), stroke volume(SV)], stroke system vascular resistance(SSVR),plethysmographic fluid conductance(TFC), systolic time ratio(STR), and left heart function [left ventricular stroke work(LSW), left ventricular stroke work index(LSWI), left ventricular ejection time(LVET)] were compared between the two groups. Results The CI, SI,and SV levels of the HFpEF group were significantly lower than those of the healthy group(P <0.05). The SSVR, TFC, and STR levels of the HFp EF group were significantly higher than those of the healthy group(P <0.05). No statistical difference was found in the LSW, LSWI, and LVET levels between the two groups(P >0.05). Conclusions TEB noninvasive hemodynamic monitor in the diagnosis of HFpEF can monitor the heart pumping function, left heart function and vascular resistance index of patients, is conducive to the early diagnosis of HFp EF, and analyze the patients’ condition, assisting the clinical development of targeted treatment.更多还原
