Stress Hyperglycemia Ratio (SHR) has been confirmed to be a predictor for adverse outcomes in cardiovascular diseases in recent years. However, the impact of SHR on one-year mortality in patients diagnosed with heart failure (HF) is still unclear. This study aims to explore the relationship between SHR and one-year mortality in HF patients, both complicated with and without diabetes mellitus (DM).
This study enrolled 3747 patients with HF from the Medical Information Mart for Intensive Care (MIMIC-IV) database. 1865 patients were set into the group of lower SHR (SHR < 0.964) and 1882 patients were in the higher group (SHR ≥ 0.964). The primary endpoint was one-year mortality.
The mean age of the total study population was 69 ± 13, and 1530 (40.8%) of them were female. Finally, 188 (5.0%) patients died in the hospital and 766 (20.4%) patients died during a one-year follow-up. Patients in the higher SHR group had a longer hospital stay (2.7% vs. 2.4%, p < 0.001) and higher in-hospital mortality (8 vs. 7, p < 0.001) than those in the lower group. The Kaplan-Meier curves also show that higher SHR is associated with an elevated risk of one-year mortality in patients with HF, both in the DM and non-DM groups (all log-rank p < 0.0001). As a continuous variable, SHR was an independent predictor for one-year mortality [hazard ratio (HR), 2.893; 95% confidence interval (CI), 2.198-3.808]. Elevated SHR was significantly associated with higher risk of one-year mortality in patients with (HR, 1.499; 95% CI, 1.104-2.036) and without DM (HR, 1.300; 95% CI, 1.096-1.542), consistently. The RCS curve shows a gradual increase in the probability of one-year mortality as the value of SHR increases for HF patients.
Our findings indicated that a higher level of SHR was associated with elevated one-year mortality in HF patients both with and without DM, suggesting that SHR is a promising stratification indicator for predicting the risk of death in patients with HF.
近年来,应激性高血糖比值(SHR)已被证实是心血管疾病不良预后的预测指标。然而,SHR对心力衰竭(HF)患者一年死亡率的影响仍不清楚。本研究旨在探讨SHR与HF患者一年死亡率之间的关系,这些患者合并或不合并糖尿病(DM)。
本研究纳入了医学重症监护信息数据库(MIMIC-IV)中的3747例HF患者。1865例患者被分为SHR较低组(SHR<0.964),1882例患者被分为较高组(SHR≥0.964)。主要终点是一年死亡率。
研究总人群的平均年龄为69±13岁,其中1530例(40.8%)为女性。最后,188例(5.0%)患者在医院死亡,766例(20.4%)患者在一年随访期间死亡。SHR较高组患者的住院时间更长(2.7%对2.4%,p<0.001),院内死亡率更高(8对7,p<0.001)。Kaplan-Meier曲线还显示,在DM组和非DM组中,较高的SHR与HF患者一年死亡风险升高相关(所有对数秩检验p<0.0001)。作为连续变量,SHR是一年死亡率的独立预测指标[风险比(HR),2.893;95%置信区间(CI),2.198 - 3.808]。SHR升高与合并DM(HR,1.499;95%CI,1.104 - 2.036)和未合并DM(HR,1.300;95%CI,1.096 - 1.542)的患者一年死亡风险较高显著相关。RCS曲线显示,随着HF患者SHR值的增加,一年死亡概率逐渐增加。
我们的研究结果表明,较高水平的SHR与合并或不合并DM的HF患者一年死亡率升高相关,这表明SHR是预测HF患者死亡风险的一个有前景的分层指标。
