摘要

目的:强化血糖治疗减少了糖尿病心血管风险控制行动(ACCORD)研究中具有触珠蛋白(Hp)2-2表型的白人参与者的冠状动脉疾病(CAD)事件,而没有Hp 2-2表型的参与者没有CAD益处。每种Hp表型的糖化血红蛋白(HbA1c)与CAD之间的关系尚不清楚。研究设计和方法:在整个研究过程中,每个表型的糖化血红蛋白都是相似的。前瞻性收集HbA1c数据(分类为结果:与7.0-7.9%的HbA1c相比,在具有Hp2-2表型的白人(调整后的HR[aHR]1.43,95%CI 1.03-1.98)和黑人(2.86,1.09-7.51)参与者中,HbA1c≥8.0%与CAD风险相关,但当所有Hp2-2参与者总体合并时(1.30,0.99-1.70)则不相关,在没有Hp2-2表现型的参与者中也不相关。HbA1c结论:在具有Hp2-2表型的白人和黑人ACCORD参与者中,HbA1c>8.0%与7.0-7.9%始终与CAD风险相关,而在没有Hp2-2表现型的参与者中没有观察到相关性。我们没有发现HbA1c浓度

The Relationship Between Time-Varying Achieved HbA1c and Risk of Coronary Events Depends on Haptoglobin Phenotype Among White and Black ACCORD Participants.

Objective: Intensive glycemic therapy reduced coronary artery disease (CAD) events among White participants in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) study with the haptoglobin (Hp)2-2 phenotype, while participants without the Hp2-2 phenotype had no CAD benefit. The association between achieved glycated hemoglobin (HbA1c) and CAD for each Hp phenotype remains unknown.

Research design and methods: Achieved HbA1c was similar in each phenotype throughout the study. Prospectively collected HbA1c data (categorized as <6.0%, 6.0-6.5%, 6.6-6.9%, or ≥8.0% compared with 7.0-7.9%) from the ACCORD study, updated every 4 months over a median of 4.7 years, were analyzed in relation to CAD in the Hp2-2 (n = 3,322) and non-Hp2-2 (n = 5,949) phenotypes separately overall, and within White (63%, 37% Hp2-2) and Black (19%, 26% Hp2-2) participants using Cox proportional hazards regression with time-varying covariables.

Results: Compared with HbA1c of 7.0-7.9%, having HbA1c ≥8.0% was associated with CAD risk among White (adjusted HR [aHR] 1.43, 95% CI 1.03-1.98) and Black (2.86, 1.09-7.51) participants with the Hp2-2 phenotype, but not when all Hp2-2 participants were combined overall (1.30, 0.99-1.70), and not among participants without the Hp2-2 phenotype. HbA1c <7.0% was not associated with a lower risk of CAD for any Hp phenotype.

Conclusions: Achieving HbA1c >8.0% compared with 7.0-7.9% was consistently associated with incident CAD risk among White and Black ACCORD participants with the Hp2-2 phenotype, while no association was observed among participants without the Hp2-2 phenotype. We found no evidence that HbA1c concentration <7.0% prevents CAD in either Hp phenotype group.
