摘要: 背景 2型糖尿病可增加患者心血管疾病的早发风险,对健康构成重大威胁。阐明2型糖尿病对扩张型心肌病患者预后的影响,有利于指导患者的管理。 目的 探讨2型糖尿病对扩张型心肌病患者预后的影响。 方法 回顾性选取广西医科大学第一附属医院心血管内科2015年1月至2020年5月收治的313例扩张型心肌病患者为研究对象。根据患者是否罹患2型糖尿病将患者分为糖尿病组(n=66)和非糖尿病组(n=247),收集患者一般资料、实验室检查指标并进行随访,随访终点事件为全因死亡,随访日期截至2021-12-31。采用landmark比较两组患者的生存率。建立多因素Cox比例风险回归模型,探究扩张型心肌病患者全因死亡的影响因素。 结果 Landmark分析结果显示,糖尿病组和非糖尿病组扩张型心肌病患者随访1年内的生存率比较,差异无统计学意义(χ2=1.520,P=0.218);随访1年后,糖尿病组扩张型心肌病患者的生存率低于非糖尿病组(χ2=4.414,P=0.036)。分段拟合法构建的多因素Cox比例风险回归分析显示,收缩压〔HR=0.965,95%CI(0.948,0.982)〕、N末端B型利钠肽原〔HR=9.928,95%CI(4.791,20.576)〕、β受体阻滞剂〔HR=0.317,95%CI(0.168,0.598)〕是扩张型心肌病患者随访1年内全因死亡的影响因素(P<0.05);左心室舒张末期内径〔HR=1.057,95%CI(1.028,1.087)〕、2型糖尿病〔HR=1.756,95%CI(1.011,3.050)〕是扩张型心肌病患者随访1年后全因死亡的影响因素(P<0.05)。 结论 2型糖尿病与扩张型心肌病患者随访1年内不良结局无关,与随访1年后的不良结局密切相关。

Abstract:

Background

Type 2 diabetes mellitus increases the risk of early onset of cardiovascular disease in patients, which poses a major threat to human health. Exploring the impact of type 2 diabetes mellitus on prognosis of patients with dilated cardiomyopathy is good for patient management.

Objective

To evaluate the effect of type 2 diabetes mellitus on the prognosis of patients with dilated cardiomyopathy.

Methods

This study retrospectively analyzed 313 patients with dilated cardiomyopathy who were admitted to the Department of Cardiology in the First Affiliated Hospital of Guangxi Medical University from January 2015 to May 2020. Patients were divided to a diabetic group (n=66) or a non-diabetic group (n=247) according to whether they suffered from type 2 diabetes mellitus. General date and laboratory indices were collected. Follow-up was conducted until December 31, 2021. The primary endpoint was all-cause death. This study used landmark analysis to compare survival rate between these two groups. A multivariate Cox proportional hazards regression model was used to analyze the influencing factors of all-cause mortality in patients with dilated cardiomyopathy.

Results

Landmark analysis showed that there was no significant difference in one-year survival rate between these two groups (χ2=1.520, P=0.218). After 1 year, the survival rate in the diabetic group was lower than that of the non-diabetic group (χ2=4.414, P=0.036). In the multivariate Cox proportional hazards regression model constructed by piecewise fitting method, systolic blood pressure〔HR=0.965, 95%CI (0.948, 0.982) 〕, N-terminal pro-B-type natriuretic peptide〔HR=9.928, 95%CI (4.791, 20.576) 〕 and β-receptor blocker〔HR=0.317, 95%CI (0.168, 0.598) 〕 were the influencing factors of all-cause mortality in patients with dilated cardiomyopathy within one year (P<0.05), while LVEDD〔HR=1.057, 95%CI (1.028, 1.087) 〕and type 2 diabetes mellitus〔HR=1.756, 95%CI (1.011, 3.050) 〕were influencing factors of all-cause mortality in patients with dilated cardiomyopathy after one year (P<0.05) .

Conclusion

Type 2 diabetes mellitus was not associated with adverse outcomes in patients with dilated cardiomyopathy at 1 year of follow-up, but was strongly associated with poor outcomes after 1 year in patients with dilated cardiomyopathy.
