Abstract

Introduction: Stress hyperglycemia (SH) in STEMI is associated with high risk of in-hospital mortality. It is still controversial if SH is marker of high post-hospital risk.

Objectives: The aim was to analyze in-hospital and one-year risk associated with SH in STEMI and to study if SH is marker of LV remodeling.

Methods: We enrolled 275 patients who were admitted with first STEMI and reperfused. Patients were divided according to admission glycemia in three groups: (1) with diabetes mellitus (DM); (2) with SH, without DM and; (3) without both DM and SH. SH was defined as admission blood glucose level ≥ 8 mmol/l.

Results: In-hospital mortality was higher in patients with known DM (5%) and highest in patients with SH without previous DM (9.3%), and only 1.6% in the third group, P < 0.05. In patients without known DM, SH was associated with 6.378-fold higher in-hospital mortality. Total mortality was double in group with SH without DM compared to the third group (13.9% versus 6.3%). EDV changed in patients with SH without DM from 126 ± 37 to 145 ± 30 ml after one year, P < 0.05.

Conclusion: SH is associated with high in-hospital mortality risk and it could be marker of LV remodeling (significant increase of EDV during one year).

急性st段抬高型心肌梗死的应激性高血糖是左室重构的标志。
STEMI患者的应激性高血糖(SH)与院内死亡的高风险相关。SH是否是高出院后风险的标志仍然存在争议。目的:分析STEMI患者与SH相关的住院和1年风险,并研究SH是否为左室重构的标志。方法:我们招募了275例首次STEMI并再灌注的患者。根据入院血糖将患者分为三组:(1)合并糖尿病(DM);(2)含SH,不含DM;(3)无糖尿病和SH, SH定义为入院血糖≥8 mmol/l。结果:已知糖尿病患者住院死亡率最高(5%),无糖尿病的SH患者住院死亡率最高(9.3%),第三组仅为1.6%,P < 0.05。在没有已知糖尿病的患者中,SH与住院死亡率高6.378倍相关。SH无DM组的总死亡率是第三组的两倍(13.9%对6.3%)。SH无DM患者1年后EDV由126±37 ml降至145±30 ml, P < 0.05。结论:SH与院内死亡风险高相关,可能是左室重构的标志(一年内EDV显著增加)。
