Abstract
Introduction: Whether glycemic variability prior to stroke increases the risk of stroke outcomes in prediabetic patients presenting with acute ischemic stroke is still unclear. We evaluated whether pre-stroke glycemic variability, estimated by glycated albumin (GA), increased early neurological deterioration (END) and functional outcomes in prediabetic patients with acute ischemic stroke. Methods: A total of 215 acute ischemic stroke patients with prediabetes were evaluated. The primary outcome was END, defined as an incremental increase in the National Institutes of Health Stroke Scale score by ≥1 point in motor power or ≥2 points in the total score within the 7 days after admission. The secondary outcome was poor functional status defined by a modified Rankin Scale at 3 months. Higher GA (≥16.0%) was determined to reflect glycemic fluctuation prior to ischemic stroke. Results: Of the 215 prediabetic patients, 77 (35.8%) were in the higher GA group. In prediabetic patients, END occurrence and poor functional status were higher in the higher GA group than in the lower GA group. The multivariate analysis showed that a higher GA was associated with an increased risk of END occurrence and poor functional outcomes at 3 months (adjusted odds ratio [95% confidence interval], 4.58 [1.64–12.81], p = 0.004 and 2.50 [1.19–5.25], p = 0.02, respectively). Conclusion: Pre-stroke glycemic variability estimated by GA was associated with END occurrence and poor functional outcome after ischemic stroke in patients with prediabetes.Keywords
