目的:观察达格列净对2型糖尿病(T2DM)伴慢性心力衰竭(CHF)患者的临床疗效以及对心外膜脂肪(EAT)厚度的影响。方法:选择2018年8月~2021年01月住院的T2DM伴心功能II~IV级CHF患者72例,随机分为治疗组和对照组各36例,两组基础治疗相同,治疗组加用达格列净,6个月后分别比较两组患者治疗前后及两组之间EAT厚度、左房前后径(LAD)、左室舒张末内径(LVDd)、左室射血分数(LVEF)、糖化血红蛋白(HbA1c)、N端脑钠肽前体(NT-proBNP)水平、6分钟步行试验(6MWT)及生活质量变化,并观察治疗效果、再住院人次及药物不良反应。结果:与治疗前相比,治疗组EAT厚度明显降低(P < 0.01),对照组无明显变化,两组治疗后LAD、LVDd、HbA1c、NT-proBNP、生活质量评分均明显下降,6MWT、LVEF明显提高(P < 0.01);治疗后组间比较,两组除LAD外,其他指标均有显著差异,以治疗组为优(P < 0.05或0.01);治疗组显效率优于对照组(P < 0.01),但总有效率与对照组无统计学差异(P > 0.05);治疗组再入院人次较对照组减低(P < 0.05),两组不良反应发生率相似(P > 0.05)。结论:T2DM伴CHF患者加用达格列净能进一步改善患者心功能,提高生活质量,降低再住院次数,使用安全性高,降低EAT厚度可能是其中一个机制。 Objective: To observe the clinical effect of Dapagliflozin on type 2 diabetes mellitus (T2DM) patients with chronic heart failure (CHF) and the influence on the thickness of epicardial adipose tissue (EAT). Methods: 72 T2DM patients with CHF of cardiac function grade II~IV who were hospitalized from August 2018 to January 2021 were randomly divided into treatment group (N = 36) and control group (N = 36). The basic treatment was the same in both groups, and Dagligliflozin was added to the treatment group. After 6 months, thickness of EAT, left atrial anter-oposterior diameter (LAD), left ventricular end-diastolic diameter (LVDd), left ventricular ejection fraction (LVEF), hemoglobin A1c (HbA1c), N-terminal pro-brain natriuretic peptide (NT-proBNP), 6-minute walking test (6MWT) and quality of life were compared before and after treatment and between the two groups. At the same time, the therapeutic effect, the number of readmission and drug reactions were observed. Results: Compared with pre-treatment, the thickness of EAT in the treatment group was significantly decreased (P < 0.01), and there was no significant change in the control group. After treatment, the scores of LAD, LVDd, HbA1c, NT-proBNP and quality of life in the two groups were significantly decreased, and 6 MWT and LVEF were significantly increased (P < 0.01). Except LAD, there were significant differences in other indexes between the two groups, the treatment group was better than the control group (P < 0.05 or 0.01). The effective rate of the treatment group was better than that of the control group (P < 0.01), but there was no significant difference in the total effective rate between the two groups (P > 0.05). The number of readmission in the treatment group was significantly lower than that in the control group (P < 0.05), and the incidence of adverse reactions was similar in the two groups (P > 0.05). Conclusion: Adding Dapagliflozin to T2DM patients with CHF can improve heart function, improve the quality of life, reduce the number of readmission, and can use safely. One of the mechanisms may be related to reducing the thickness of EAT.

慢性心力衰竭(chronic heart failure, CHF)是各种心脏病的严重阶段,其发病率高,预后差,因此有必要探索新的治疗手段包括药物以改善患者的生活质量及预后。目前国外多项研究证实钠–葡萄糖共转运蛋白2 (SGLT-2)抑制剂可以降低2型糖尿病(type 2 diabetes mellitus, T2DM)患者发生心力衰竭住院治疗的风险,并改善CHF预后 [
选取2018年8月~2021年01月在我院心内科、内分泌科住院的T2DM伴心功能II~IV级(NYHA分级) CHF患者72例,纳入标准:CHF诊断符合《中国心力衰竭诊断和治疗指南2018》 [
两组患者均按照CHF诊治指南,常规治疗原发病,并选择二甲双胍、格列美脲片、利尿剂(包含醛固酮受体拮抗剂)、血管紧张素转换酶抑制剂或血管紧张素受体拮抗剂、选择性加用β受体阻滞剂、洋地黄类强心剂、胰岛素等作为基础治疗;治疗组在常规治疗的基础上加用达格列净(安达唐)治疗,每次10 mg,每天1次口服,6个月后评价疗效。
① 用药过程中观察症状改善情况、药物的副作用;② 治疗前及治疗6个月后检查肝、肾功能、空腹血糖、HbA1c、血脂、电解质、血清NT-proBNP;③ 心脏超声检查:受检者取左侧卧位,平稳呼吸,由同一具有丰富操作经验的医师通过超声心动图(ACUSONSC-2000彩超,探头频率为3.0 MHz),选取胸骨旁左室长轴切面,以主动脉瓣环为定位基准,超声束中线与右室游离壁相垂直,于心室收缩末期即心电图T波终点冻结图像,测量心肌外层与脏层心包之间的无、低或中等回声区的宽度,确立EAT厚度,同时按照《中国成年人超声心动图检查测量指南》推荐测量方法 [
患者空腹过夜10小时以上,采静脉血10 ml加入抗凝试管中,离心后(3000 r/min, 10 min)血清保存于−20℃冰箱,2个月内备检。血清NT-proBNP测定采用电化学发光免疫法,肝肾功能、电解质、血脂、空腹血糖、HbA1c采用全自动生化分析仪检测。
根据卫生部1993年颁布的《新药治疗研究指导原则》标准制定,心功能评价采用NYHA分级。显效:心功能改善二级或以上;有效:心功能改善一级;无效:心功能无明显变化或加重;死亡。显效 + 有效为总有效。
利用stata12.0软件包对数据进行处理,计量资料用平均值 ± 标准差( x ¯ ± s)表示,组间两样本均数比较采用t检验,组内用药前、后比较采用自身配对t检验,计数资料采用χ2检验或精确概率法,P < 0.05为差异有统计学意义。
对照组两例于观察期内病情恶化死亡,其检测指标不纳入统计。结果发现:与治疗前相比,对照组EAT厚度治疗后变化不明显(P > 0.05),而治疗组治疗后EAT厚度明显降低(P < 0.01);两组治疗后HbA1c、LAD、LVDd、NT-proBNP、MLWHFQ评分均明显下降,6MWT、LVEF明显提高(P均 < 0.01);两组治疗后组间指标比较,除LAD外,其他指标均有显著差异,以治疗组为优(P < 0.05或0.01),见表1。两组治疗后肝肾功能、血脂、电解质比较无统计学差异(P均 > 0.05)。

CHF是一种复杂的临床症状群,为各种心脏病的严重阶段,尽管近20多年来心衰的药物及非药物治疗有了划时代的进展,但其预后仍然较差,因此心衰的治疗除了现有方法外,必须探索其他新的治疗手段包括药物以改善生活质量及预后,减少住院及死亡率。
达格列净作为SGLT-2抑制剂,可以抑制肾脏对葡萄糖的重吸收,直接降低血糖。目前多项研究证实了SGLT-2抑制剂对于T2DM患者具有心血管保护作用 [
本研究结果进一步证实了上述结论,我们观察了在常规药物基础上加用达格列净治疗T2DM伴CHF的临床疗效,结果显示:常规治疗加达格列净组(治疗组)显效率优于常规治疗组(对照组),两组均可明显降低血糖、改善心房、心室扩大、提高LVEF,降低血清NT-proBNP,增加6MWT,提高生活质量,除LAD大小外,治疗组优势更加明显,并能进一步降低再住院次数(P < 0.05或0.01),两组治疗前后肝肾功能、电解质变化、不良反应发生率差异不显著(P > 0.05),提示达格列净对T2DM伴CHF心功能有进一步改善作用,并且安全性较高。
EAT是位于脏层心包与心肌之间的一种特殊的内脏脂肪,被认为是一种活跃的分泌组织,具有较高的促炎细胞因子(TNFα,IL-6,IL-1β等)表达能力 [
综上,T2DM伴CHF患者加用达格列净治疗后,可明显减少患者EAT厚度,进一步改善心脏功能,提高生活质量、减少再住院率,使用安全,值得临床进一步推广应用。
