Longitudinal Association Between Fasting Blood Glucose C 2017 The American J

This large Chinese study followed over 20,000 adults with high blood pressure for about 4.5 years to understand how blood sugar levels affect stroke risk. All participants had no history of stroke or heart attack at the start. Researchers divided them into two groups: one received blood pressure medication plus folic acid supplements, while the other received only blood pressure medication.

The results showed a clear connection between blood sugar levels and stroke risk. People with high fasting blood sugar (≥7.0 mmol/L, which indicates diabetes) had more than double the stroke risk compared to those with low blood sugar (<5.0 mmol/L) - 6.0% versus 2.6% developed strokes during the study period. This confirms that elevated blood sugar, even in people without a previous stroke history, significantly increases the chance of having a first stroke.

Importantly, the study found that folic acid supplementation provided protective benefits. Participants who took folic acid along with their blood pressure medication had reduced stroke risk associated with higher glucose levels. This suggests that this common B vitamin may help counteract some of the vascular damage caused by elevated blood sugar.

For patients focused on metabolic health and longevity, this research emphasizes the critical importance of maintaining healthy blood sugar levels through diet, exercise, and appropriate medical management. It also suggests that folic acid supplementation might be a valuable addition to stroke prevention strategies, particularly for those with elevated glucose levels or diabetes. Patients should discuss their individual stroke risk factors and potential benefits of folic acid supplementation with their healthcare provider as part of a comprehensive metabolic health plan.
