| 摘 要： | 目的 探讨血清25-羟维生素D25(OH)D]水平缺乏与老年射血分数保留心力衰竭(HFpEF)的关系。 方法 选取2019年1月—2020年12月就诊于南京医科大学第一附属医院老年心血管科的老年患者219例，其中HFpEF患者118例，对照组101例。收集患者一般资料，检测常规生化指标、25(OH)D和N末端B型脑钠肽前体(NT-proBNP)水平；心脏超声检查测定心脏结构和功能，并对血清25(OH)D和HFpEF心脏结构功能指标进行相关分析，就老年HFpEF危险因素进行多因素逐步logistic回归分析。 结果 老年HFpEF组血清25(OH)D水平(37.58±12.92)nmol/L]较对照组(60.82±13.61)nmol/L]明显降低(P < 0.001)；且HFpEF组心脏超声相关指标左房内径(LAD)、左室舒张末期内径(LVDd)、左室收缩末期内径(LVDs)、室间隔厚度(IVS)、左心室质量指数(LVMI)、二尖瓣口E峰流速与二尖瓣环舒张早期峰值速度比值(E/e')、左房容积指数(LAVI)、三尖瓣反流速度(TRV)、肺动脉收缩压(PASP)均高于对照组，左室射血分数(LVEF)、二尖瓣环舒张早期峰值速度(e')平均值低于对照组，差异有统计学意义(均P < 0.05)。Spearman相关分析显示，25(OH)D与LAD、IVS、左室后壁厚度(LVPW)、LVMI、E/e'、LAVI、TRV、PASP、NT-proBNP呈负相关，与e' 平均值呈正相关(均P < 0.05)。多因素逐步logistic回归分析表明:血清25(OH)D水平是老年HFpEF的独立影响因素(OR=0.814，95% CI:0.723~0.916，P=0.001)。 结论 25(OH)D缺乏与老年HFpEF有关，是老年HFpEF的独立危险因素。

| Abstract: | Objective To investigate the correlation between serum 25-hydroxyvitamin D 25(OH)D] deficiency and heart failure with preserved ejection fraction in the elderly. Methods A total of 219 elderly patients treated in the Department of Geriatric Cardiology of the First Affiliated Hospital of Nanjing Medical University from January 2019 to December 2020 were enrolled and divided into the HFpEF group (n=118) and control group (n=101). General data, routine biochemical index results, 25(OH)D, NT-ProBNP and echocardiography parameters of all patients were collected and compared. The correlation between serum 25(OH)D level and echocardiographic parameters was analysed, and the risk factors of HFpEF were analysed by multivariate stepwise logistic regression. Results The level of 25(OH)D in the HFpEF group (37.58±12.92) nmol/L] was significantly lower than that in the control group (60.82±13.61) nmol/L, P < 0.001]. The HFpEF group had higher echocardiographic parameters such as LAD, LVDd, LVDs, IVS, LVMI, E/e', LAVI, TRV and PASP and lower LVEF and average e' compared with the control group (all P < 0.05). Spearman correlation analysis showed that the 25(OH)D level was negatively correlated with LAD, IVS, LVPW, LVMI, E/e', LAVI, TRV, PASP and NT-proBNP and was positively correlated with average e' (all P < 0.05). Multivariate stepwise logistic regression analysis showed that 25(OH)D level was an independent influence factor for HFpEF in the elderly (OR=0.814, 95% CI: 0.723-0.916, P=0.001). Conclusion 25(OH)D deficiency is related to HFpEF and can be an independent risk factor for elderly HFpEF. |
