Abstract
Introduction
The study aimed to identify the main prognostic factors in diabetic patients with ischemic stroke undergoing reperfusion therapies (RT).
Methods
This retrospective study included 170 diabetic patients: 62 treated with intravenous thrombolysis (IVT) alone and 108 with mechanical thrombectomy (MT). Among MT patients, 29 underwent IVT. We collected clinical, laboratory, and radiological data. The outcomes were 3-month functional impairment (measured by modified Rankin scale, mRs), discharge neurological severity (measured by National Institutes of Health Stroke Scale score, NIHSS), 3-month mortality, intracranial hemorrhage (ICH), and symptomatic intracranial hemorrhage (SICH). We performed a general analysis for all RT and sub-group analyses for IVT and MT.
Results
A lower mRs was associated with lower glycemia and admission NIHSS (aNIHSS) in all RT and MT; lower aNIHSS and younger age in IVT. Mortality increased with hyperglycemia, aNIHSS, and age in all RT; age and aNIHSS in IVT; hyperglycemia and systolic pressure in MT. A lower discharge NIHSS was related with lower aNIHSS, thrombolysis, and no thrombectomy in all RT; lower aNIHSS in IVT; lower aNIHSS and thrombolysis in MT. ICH was associated with elevated aNIHSS, older age, and lower platelets in all RT; lower platelets and older age in IVT; higher aNIHSS in MT. SICH depended on longer thrombectomy duration in all RT; no metformin use in IVT; higher weight in MT.
Conclusion
The study shed light on diabetic patients and stroke RT highlighting the protective effect of metformin in IVT and the role of glycemia, weight, and combined treatment in MT.
