Abstract: Objective To analyze the effect of stress hyperglycemia ratio (SHR) on the emergency outcome of elderly patients with heart failure. Methods A retrospective analysis was carried out on the clinical data of 106 elderly patients with heart failure admitted to our hospital from January 2018 to January 2021. The patients were divided into poor outcome group (n=68) and good outcome group (n=38) according to the emergency outcome. The endpoint events of the elderly patients with heart failure in poor outcome group were analyzed. The clinical data of the two groups were analyzed, and Logistic regression analysis was used to identify the risk factors for poor emergency outcome in the elderly patients with heart failure. The predictive value of SHR for poor emergency treatment in the elderly patients with heart failure was analyzed. Results A total of 68 out of 106 patients had adverse endpoint events, and 48 cases were major adverse cardiovascular events (MACE), with all-cause deaths (19.81%) as the main cause; the other 20 cases were the secondary endpoint events, with recurrence of angina pectoris (11.32%) as the main cause. Multivariate Logistic analysis showed that age ≥ 60 years, LVEF <40%, cardiogenic shock, SHR ≥ 1.05, NT-proBNP ≥ 5000 μg/L, WBC ≥ 7×10⁹/L were the risk factors of poor emergency outcome in the elderly patients with heart failure (P<0.05). SHR has a sensitivity of 73.5% and a specificity of 73.7% in predicting poor emergency outcome in the elderly patients with heart failure. Conclusions SHR≥1.05 is a risk factor for poor emergency outcome in the elderly patients with heart failure, which has a better predictive value for poor emergency outcome.
