CGM in Acute Ischemic Stroke

Starting soon · Not applicable

Conditions studied: Acute Ischemic Stroke, Diabetes (DM), Diabetes Type 2, Hyperglycemia, Stroke

In brief

The goal of this randomized clinical trial is to evaluate whether continuous glucose monitoring (CGM) can be used to guide glucose management in patients with type 2 diabetes who are admitted with an acute ischemic stroke and undergo endovascular therapy. Hyperglycemia frequently occurs during hospitalization in stroke and is associated with worse neurological and clinical outcomes. In current clinical practice, glucose levels are monitored using intermittent point-of-care testing (POCT) with finger-prick measurements, which may miss clinically relevant glucose fluctuations. CGM provides continuous glucose measurements and may allow earlier detection of hyperglycemia and more timely glucose management. This study is designed as a non-inferiority randomized controlled trial comparing CGM-guided glucose management with standard POCT-guided glucose management. The primary objective is to determine whether CGM-guided glucose management is non-inferior to POCT-guided management in terms of percentage time spent in hyperglycemia (glucose \>10 mmol/L) during the first 72 hours of hospitalization. Researchers will compare CGM-guided glucose management to POCT-guided glucose management to evaluate whether CGM can be used as an alternative strategy to guide glucose control in hospitalized stroke patients. Participants will: * Be randomly assigned to either CGM-guided glucose management or standard POCT-guided glucose management * Have their glucose levels continuously monitored (blinded in the POCT-guided group) during hospitalization * Receive glucose management according to the assigned monitoring strategy, based on the hospital insulin protocol
