Vascularization Pattern After Ischemic Stroke is Different in Control Versus Diabetic Rats: Relevance to Stroke Recovery Basic Sciences
Conclusions— Diabetes mellitus impairs poststroke reparative neovascularization and impedes the recovery. Glycemic control after stroke can improve neurovascular repair and improve functional outcome.

Effect of metformin on outcome after acute ischemic stroke in patients with type 2 diabetes mellitus
Diabetes mellitus is a well-known risk factor for ischemic stroke and is associated with unfavorable outcome after stroke. Metformin is recommended as first-line treatment in these patients. Pre-stroke metformin use might have neuroprotective properties resulting in reduced stroke severity. However, results of the effects of pre-stroke metformin use on functional outcome are conflicting and has not been previously described in patients with type 2 diabetes mellitus regardless of stroke severity or revascularization treatment.

Safety and feasibiLIty of Metformin in patients with Impaired glucose Tolerance and a recent TIA or minor ischemic stroke (LIMIT) trial – a multicenter, randomized, open‐label phase II trial
ConclusionsTreatment with metformin in patients with TIA or minor ischemic stroke and impaired glucose tolerance is safe, but leads to minor side effects. If tolerated, it may lead to a significant reduction in post‐load glucose levels. This suggests that the role of metformin as potential therapeutic agent for secondary stroke prevention should be further explored.

Impact of glucose-lowering therapies on risk of stroke in type 2 diabetes.
Abstract Patients with type 2 diabetes (T2D) have an increased risk of stroke compared with people without diabetes. However, the effects of glucose-lowering drugs on risk of ischaemic stroke in T2D have been less extensively investigated than in coronary heart disease. Some evidence, including the UKPDS, has suggested a reduced risk of stroke with metformin, although the number of studies is limited. Inhibition of the KATP channels increases ischaemic brain lesions in animals. This is in agreement with a recent meta-analysis showing an increased risk of stroke with sulphonylureas vs. various comparators as both m...

Sex differences in outcomes after stroke among patients with low total cholesterol levels: a large hospital-based prospective study
ConclusionsThese findings suggest that patients (both men and women) with atherothrombotic infarction who have low TC levels would not benefit from receiving statin treatment. Therefore, it is crucial to explore the impact of statin treatment on outcomes in Asian patients, especially Chinese patients with atherothrombotic and low TC levels, in order to improve outcomes after stroke and reduce the disease burden.

Diabetes: Chronic Metformin Treatment and Outcome Following Acute Stroke
ConclusionSimilar to previous reports, our study shows that diabetes adversely affects stroke outcome. The use of prior metformin is associated with better outcome in patients with ischemic stroke and results in lower mortality. The positive effects of metformin require further research to better understand its mechanism.

Antidiabetic drugs and stroke risk. Current evidence.
Abstract Cardiovascular disease (CVD) is the major cause of morbidity and mortality for individuals with type 2 diabetes (T2D). In particular, the risk for stroke is twice that of patients without diabetes, and diabetes may be responsible for >8% of first ischemic strokes. Therefore, the way to prevent stroke in these patients has become an important issue. Traditionally, glucose-lowering drugs had not been shown to protect against stroke. Moreover, several antidiabetic drugs (i.e., sulfonylureas, rosiglitazone) have been reported to be associated with increased risks of CVD and stroke. On the contrary, data on...

Involvement of arterial baroreflex and nicotinic acetylcholine receptor α7 subunit pathway in the protection of metformin against stroke in stroke-prone spontaneously hypertensive rats.
In conclusion, Met improved the arterial baroreflex function, and then enhancing cholinergic anti-inflammatory pathway in an α7nAChR-dependent manner, thereby effectively prevent ischemic induced brain injury and delayed stroke onset in SHRSP. PMID: 28132912 [PubMed - as supplied by publisher]

Association of glucose-lowering drugs with incident stroke and transient ischaemic attacks in primary care patients with type 2 diabetes: disease analyzer database

The Effect of Metformin on Vitamin B12 Deficiency and Stroke
CONCLUSIONS: T2DM is a significant risk factor to the development of ischemic stroke. We found an association between metformin use and vitamin B12 deficiency and an association between vitamin B12 deficiency and stroke risk in patients with T2DM. Diabetic patients who are taking metformin should monitor their vitamin B12 level.PMID:36841981
