Abstract

Background: The aim of the present study was to clarify the effect of glucose profiles after stroke, which was assessed by a continuous glucose monitoring (CGM) device.

Methods: Acute ischemic stroke patients within 24 h of onset were prospectively studied. CGM was performed for 72 h after admission. CGM parameters were evaluated as follows: (1) mean glucose level, (2) area under the curve (AUC) for glucose level >140 mg/dl and (3) SD of the glucose level. Infarct volume was measured at admission and 24 and 72 h after admission using diffusion-weighted imaging. CGM data and infarct volume growth were compared at 24 and 72 h.

Results: Seventy-eight patients were enrolled in the present study. Spearman's rank correlation coefficients showed that both the mean glucose level (r = 0.433, p < 0.001 for 24 h; r = 0.308, p = 0.006 for 72 h) and AUC >140 mg/dl (r = 0.417, p < 0.001 for 24 h; r = 0.277, p = 0.014 for 72 h) were significantly correlated with acute infarct volume growth. The SD of the glucose level was associated with infarct volume growth at 24 h (r = 0.303, p = 0.007), but not 72 h (r = 0.195, p = 0.088).

Conclusion: Post-stroke hyperglycemia was associated with infarct volume growth during the acute phase of ischemic stroke.
