摘要 目的 分析射血分数保留的心力衰竭患者心肌能量消耗(MEE)情况及预后不良的相关因素。方法 回顾性收集2020年1月~2021年1月我院收治的107例射血分数保留的心力衰竭患者临床资料,所有患者均进行超声心动图检查,且出院后均随访6月,根据患者随访期间是否发生不良心血管事件(MACE)将患者分为预后良好组(n=72)和预后不良组(n=35)。统计分析射血分数保留的心力衰竭患者预后不良的单因素,采用多因素Logistic回归分析射血分数保留的心力衰竭患者预后不良的危险因素,并对典型病例超声心动图图像进行分析。结果 107例射血分数保留的心力衰竭患者中,共35例发生MACE,不良预后发生率为32.71%。单因素分析结果显示,预后不良组外周血红细胞计数、血红蛋白水平及左室射血分数(LVEF)低于预后良好组,血清脑钠肽水平及MEE高于预后良好组(P<0.05)。多因素Logistic回归分析结果显示,血清脑钠肽水平高、MEE高、LVEF低均为射血分数保留的心力衰竭患者预后不良的独立危险因素(OR=2.457、3.083、2.986,P<0.05)。结论 射血分数保留的心力衰竭患者预后不良的独立危险因素包括血清脑钠肽水平高、MEE高、LVEF低,超声心动图MEE和LVEF可用于预测射血分数保留的心力衰竭患者MACE的发生。 Objective To analyze the myocardial energy expenditure(MEE) and related factors of poor prognosis in heart failure patients with preserved ejection fraction. Methods Clinical data of 107 patients with heart failure with retained ejection fraction admitted to our hospital from January 2020 to January 2021 were retrospectively collected. All patients underwent echocardiography and were followed up for 6 months after discharge. Patients were divided into the good prognosis group(n=72) and the poor prognosis group(n=35) according to whether adverse cardiovascular events(MACE) occurred during followup. Single factors for poor prognosis in patients with heart failure with preserved ejection fraction were statistically analyzed using multifactorial logistic regression and echocardiographic images were analysed in typical cases. Results A total of 35 of107 heart failure patients with preserved ejection fraction developed MACE, with an incidence of poor prognosis of 32.71%.Univariate analysis showed that the levels of erythrocyte count, hemoglobin and left ventricular ejection fraction(LVEF) in the poor prognosis group were lower than those in the good prognosis group(P<0.05), while the levels of serum brain natriuretic peptide and MEE were higher than those in the good prognosis group(P<0.05). Multivariate Logistic regression analysis showed that high level of serum brain natriuretic peptide, high MEE and low LVEF were independent risk factors for poor prognosis in heart failure patients with retained ejection fraction(OR=2.457, 3.083, 2.986, P<0.05). Conclusion The independent risk factors for poor prognosis in patients with retained ejection fraction include high level of serum brain natriuretic peptide,high MEE and low LVEF. Echocardiographic MEE and LVEF could be used to predict the development of MACE in patients with heart failure with preserved ejection fraction.
