Insights
High admission and fluctuating glucose levels in patients with subarachnoid hemorrhage (SAH) predict increased 1-year mortality. Monitoring blood glucose is crucial for predicting outcomes in SAH patients without diabetes.
Area of Science:
- Neuroscience
- Endocrinology
- Critical Care Medicine
Background:
- Subarachnoid hemorrhage (SAH) is a critical neurological condition.
- Glycemic control is increasingly recognized as a significant factor in patient outcomes across various medical conditions.
Purpose of the Study:
- To investigate the association between fasting glucose levels on admission, day 14, and their variation with 1-year mortality in patients with SAH.
- To identify glucose level dynamics as potential predictors of mortality following SAH.
Main Methods:
- A prospective study involving 239 SAH patients without a history of diabetes.
- Analysis of fasting glucose levels at admission and day 14, along with their changes.
- Multivariate Cox regression analysis to determine risk factors for 1-year mortality.
Main Results:
- 1-year mortality rate was 11.7% in the studied cohort.
- Admission glucose levels were significantly associated with 1-year mortality (HR: 1.524 per mmol/L).
- Increased fasting glucose levels within 14 days and higher glucose levels in non-survivors were observed, correlating with elevated 1-year mortality (HR: 1.350 per mmol/L).
Conclusions:
- Fasting glucose levels upon admission and their subsequent variation in SAH patients are significant predictors of 1-year mortality.
- These findings highlight the importance of glycemic monitoring in managing SAH patients.
Objectives:
To assess whether the fasting glucose level on admission, day 14 or their variation in patients with aSAH was associated with 1-year mortality.
Methods:
A prospective study was undertaken to analyze the effects of fasting glucose on admission, day 14 and their variation on the 1-year mortality rate after aSAH. Patients with aSAH were enrolled to assess the mortality rate relationship with fasting glucose, medical history, clinical and radiological grades. Multivariate Cox regression analysis was performed to assess risk factors for 1-year mortality.
Results:
A total of 239 aSAH patients without history of diabetes were followed up, with the 1-year mortality being 11.7%. Admission glucose levels were found to be associated with 1-year mortality after being adjusted for other confounding factors in Cox regression (HR: 1.524 per mmol/L; 95%CI, 1.250-1.859). Within 14 days, fasting glucose levels of 85 patients had increased. Patients who died also exhibited higher levels of glucose (dead vs. survival: 61.54% vs. 33.66%, p<0.01). In addition, higher blood glucose levels were associated with an elevated 1-year mortality (HR: 1.350 per mmol/L; 95%CI, 1.153-1.580).
Conclusions:
Glucose levels at admission as well as their variation after aSAH are predictive of an elevated 1-year mortality rate.
