Blood sugar control has always been important for people with diabetes when it comes to preventing a stroke.

A recent study from Seoul National University found for people with diabetes who have a stroke, there may be an ideal target blood sugar range to lower the risk of different types of vascular diseases like a stroke or heart attack later on.

They found that there is an optimal blood sugar level that may start to minimize the risk of having another stroke, a heart attack or other vascular problems, and it’s right in the 6.8% to 7.0% range.

In the study, the team tested 18,567 people with diabetes with an average age of 70. All participants were admitted to the hospital for an ischemic stroke, which is caused by a blood clot.

Upon admission, researchers used a test called the hemoglobin A1C to determine people’s average blood sugar level over the past two to three months. This test measures the percentage of hemoglobin proteins in the blood coated with sugar.

A level below 5.7% is considered normal; 6.5% or higher generally indicates diabetes. The participants had an average A1C of 7.5%.

Researchers then followed up one year later to find out if there was an association between A1C levels with the risk of having another stroke, a heart attack, or dying from these or other vascular causes.

They found that people admitted to the hospital with A1C levels above the 6.8% to 7.0% range had an increased risk of having a vascular event like a heart attack, as well as another stroke.

Further analyses showed people’s risk for a heart attack or similar vascular diseases was 27% greater when they were admitted to the hospital with A1C levels above 7.0%, compared to those admitted with A1C levels below 6.5%.

People’s risk of having another stroke was 28% greater when admitted to the hospital with A1C levels above 7.0%, compared to those below 6.5%.

The findings highlight the importance of keeping a close eye on your blood sugar if you’re diabetic and have had a stroke.

If you care about blood sugar, please read studies that eating eggs in breakfast may control blood sugar, and this blood sugar drug also can reduce blood vessel aging.
