ABSTRACT
OBJECTIVE: Cardiovascular disease (CVD) and cerebrovascular disease are the leading cause of death around the world all the time. A novel marker described as the stress hyperglycemia ratio (SHR) can reflect the acute hyperglycemic status and is associated with poor outcomes in patients with acute illness, such as stroke and myocardial infarction (MI). Our previous study has shown that SHR was strongly related to the clinical outcomes of stroke patients. Nevertheless, the association between SHR and clinical outcomes in patients with CVD is still unclear and controversial. Consequently, in the current study, we analyzed the association of SHR and clinical outcomes in CVD patients by systematic review and meta-analysis.
MATERIALS AND METHODS: We searched the electronic databases to identify SHR studies of patients who met the eligibility criteria for CVD. We performed our study complying with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We utilized a ten terms tool to assess the potential bias of included studies. Major adverse cardiovascular and cerebrovascular events (MACCEs), all-cause death, left ventricular ejection fraction (LVEF), and other exciting outcome data were extracted for statistical analysis. Moreover, we used the DerSimonian and Laird random-effects model to perform the meta-analysis and conducted subgroup analyses to identify factors associated with substantial heterogeneity.
RESULTS: The study cohort included nine studies comprising 32,292 patients with CVD. Our meta-analysis found that MACCEs in the high SHR group were 1.68 folds compared with that in the low SHR group [odds ratio (OR) 1.68, 95% confidence interval (CI) 1.41-2.00, p < 0.00001]. Besides, all-cause death in the high SHR group was 1.52 folds compared with that in the low SHR group (OR 1.52, 95% CI 1.15-2.01, p < 0.00001). Higher SHR meant the lower LVEF (mean difference [MD] -2.03, 95% CI [-3.28-0.79], p = 0.001). The risk of cardiogenic shock and stroke were 2.47 and 1.53 folds in the high SHR group, respectively, compared with the low SHR group. Yet, no statistically significant difference was observed for revascularization (OR 0.88, 95% CI 0.77-1.01, p = 0.08), recurrent MI (OR 1.27, 95% CI 0.69-2.33, p = 0.44), and left ventricular end-diastolic diameter (LVEDD) (MD 0.61, 95% CI [-1.65, 2.87], p = 0.60) between the two groups. Subgroup analyses identified that different study design was associated with heterogeneity about MACCEs and LVEF. Besides, studies from different countries were associated with heterogeneity about all-cause death.
CONCLUSIONS: Higher SHR significantly increases the occurrence of MACCEs and all-cause death and decreases LVEF. Moreover, Higher SHR means a higher risk of cardiogenic shock and stroke. Nevertheless, SHR had no relationship with revascularization, recurrent MI, and LVEDD. As a novel and non-invasive marker, SHR should be paid more attention to in clinical practice. Future investigation should focus on the diagnostic value of SHR in CVD and the early control of stress hyperglycemia. Although no randomized, double-blind studies have been conducted, the available massive sample studies reflect the actual situation in the clinic and assist clinical decision-making.
