Blood sugar control has always been important for people with diabetes when it comes to preventing a stroke.
In a new study from Seoul National University, researchers 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 a 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 having 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 for 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.
