Prognostic Impact of Plasma Glucose on Patients With Cardiogenic Shock With or Without Diabetes Mellitus from the SMART RESCUE Trial

초록

Although the presence of hyperglycemia has been shown to affect the clinical outcome of patients with cardiogenic shock, the extent of hyperglycemia and its association with prog-nosis have not been fully addressed in a large population. A total of 1,177 consecutive patients with cardiogenic shock were enrolled from January 2014 to December 2018 at 12 hospitals in South Korea. The primary outcome was in-hospital mortality. Patients were divided into 4 groups according to their initial plasma glucose level in patients with diabe-tes mellitus (DM) (n = 752) and patients without DM (n=425); group 1 (<= 8 mmol/L or 144 mg/100 ml), group 2 (8 to 12 mmol/L or 144 to 216 mg/100 ml), group 3 (12 to 16 mmol/L or 216 to 288 mg/100 ml), and group 4 (>= 16 mmol/L or 288 mg/100 ml). The groups with higher admission plasma glucose were associated with lower systolic blood pressure and higher lactic acid levels in patients with and without DM. In-hospital mortal-ity increased in groups with higher admission plasma glucose level in patients without DM (group 1:24.2%, group 2: 28.6%, group 3: 38.1%, group 4: 49.0%, p < 0.01), whereas in patients with DM, mortality and admission plasma glucose level showed no significant association (group 1: 45%, group 2: 35.4%, group 3: 33.3%, group 4: 43.1%, p = 0.26). Even after multivariate analysis, high plasma glucose was an independent predictor of in-hospital mortality in patients without DM. In patients with cardiogenic shock, plasma glu-cose obtained at admission was associated with in-hospital mortality in patients without DM.(C) 2022 Elsevier Inc. All rights reserved.
