Abstract

INTRODUCTION

This study sought to determine whether the association between attaining specific glycated hemoglobin (HbA) targets (<7.0% (<53 mmol/mol) and ≥8.0% (≥64 mmol/mol) compared with 7.0%-7.9%) over time and risk of incident coronary artery disease (CAD) was dependent on haptoglobin (Hp) phenotype in the Action in Diabetes and Vascular Disease: Preterax and Diamicron Modified Release Controlled Evaluation (ADVANCE) study.

RESEARCH DESIGN AND METHODS

Prospectively collected HbA data from the ADVANCE biomarker case-cohort study, updated at 6 months and every 12 months thereafter over a median of 5.0 (IQR 4.5-5.3) years, were analyzed in relation to incident CAD in the Hp2-2 (n=1323) and non-Hp2-2 (n=2069) phenotypes separately using weighted multivariable-adjusted Cox regression models. Additional a priori stratifications by sex, race, previous cardiovascular disease (CVD), and type 2 diabetes duration were performed.

RESULTS

Mean HbA was similar in each phenotype group throughout the study. Compared with HbA of 7.0%-7.9%, HbA <7.0% was not associated with CAD risk for any phenotype group or subgroup. HbA ≥8.0% compared with 7.0%-7.9% over time was associated with higher CAD risk for the Hp2-2 phenotype only (HR 1.53, 95% CI 1.01 to 2.32; no significant association in the non-Hp2-2 type: 1.26, 0.89 to 1.77, p-interaction=0.71); this was pronounced when those with previous CVD at baseline were excluded (Hp2-2: 2.80, 1.41 to 5.53, p-interaction=0.03). Compared with HbA of <8.0%, having HbA ≥8.0% was associated with a 59% higher CAD risk among participants with the Hp2-2 phenotype (1.59, 1.12 to 2.26) and a 39% higher CAD risk among participants without the Hp2-2 phenotype (1.39, 1.03 to 1.88, p-interaction=0.97).

CONCLUSIONS

The present ADVANCE analysis suggests that not having HbA ≥8.0%, rather than achieving HbA <7.0%, was found to be particularly important for CAD prevention among people with type 2 diabetes and the common Hp2-2 phenotype. While the subgroup analyses were likely underpowered, their inclusion is hypothesis generating and can be used in future meta-analyses to improve power and generalizability.

摘要

引言

在糖尿病和血管疾病行动：培哚普利和达美康缓释片对照评估（ADVANCE）研究中，本研究旨在确定随着时间推移达到特定糖化血红蛋白（HbA）目标（<7.0%（<53 mmol/mol）和≥8.0%（≥64 mmol/mol），与7.0%-7.9%相比）与冠心病（CAD）发病风险之间的关联是否取决于触珠蛋白（Hp）表型。

研究设计与方法

前瞻性收集ADVANCE生物标志物病例队列研究中的HbA数据，此后每6个月更新一次，每12个月更新一次，中位数为5.0（四分位间距4.5 - 5.3）年，分别使用加权多变量调整Cox回归模型分析Hp2 - 2（n = 1323）和非Hp2 - 2（n = 2069）表型中与CAD发病的关系。还按性别、种族、既往心血管疾病（CVD）和2型糖尿病病程进行了额外的先验分层。

结果

在整个研究过程中，各表型组的平均HbA相似。与7.0%-7.9%的HbA相比，HbA <7.0%与任何表型组或亚组的CAD风险均无关联。随着时间推移，与7.0%-7.9%相比，HbA≥8.0%仅与Hp2 - 2表型的CAD风险较高相关（风险比[HR] 1.53，95%置信区间[CI] 1.01至2.32；非Hp2 - 2型无显著关联：1.26，0.89至1.77，交互作用p值 = 0.71）；当排除基线时有既往CVD的患者时，这种关联更为明显（Hp2 - 2：2.80，1.41至5.53，交互作用p值 = 0.03）。与<8.0%的HbA相比，HbA≥8.0%使Hp2 - 2表型参与者的CAD风险升高59%（1.59，1.12至2.26），使无Hp2 - 2表型参与者的CAD风险升高39%（1.39，1.03至1.88，交互作用p值 = 0.97）。
