New Online Calculator Helps Predict Stroke Risk

A new scoring tool developed by a UVA Children's pediatrician and his collaborator at the University of Florida helps identify patients at stroke risk and help them reduce that risk.

Doctors can use this information - and a scoring tool developed by a UVA Children's pediatrician and his collaborator at the University of Florida - to identify patients at risk and help them reduce that risk.

How to Deal with a Stroke - Signs - Symptoms - Risk Factors - Prevention
Stroke is a brain attack, which occurs when the blood supply to the brain is interrupted. It affects all age groups; according to the WHO, 15 million people are affected by stroke annually.

‘Stroke risk increased consistently with metabolic syndrome severity even in patients without diabetes.’

"We had previously shown that the severity of metabolic syndrome was linked to future coronary heart disease and type 2 diabetes," said UVA's Mark DeBoer, MD. "This study showed further links to future ischemic strokes."

Ischemic Stroke Risk

DeBoer developed the scoring tool, an online calculator to assess the severity of metabolic syndrome, with Matthew J. Gurka, PhD, of the Department of Health Outcomes and Biomedical Informatics at the University of Florida, Gainesville. The tool is available for free at https://metscalc.org/.

Quiz on Stroke
Stroke is the third leading cause of death world over. Besides, it also disables the affected people, making them completely dependent on caregivers for their daily needs. Lifestyle greatly affects the chances of developing a stroke. Thus, the incidence of stroke can be brought down to a great extent by leading a healthy lifestyle. Here is a quiz that tests if you know enough about this disabling condition.

To evaluate the association between ischemic stroke and metabolic syndrome, DeBoer and Gurka reviewed more than 13,000 participants in prior studies and their stroke outcomes. Among that group, there were 709 ischemic strokes over a mean period of 18.6 years assessed in the studies. (Ischemic strokes are caused when blood flow to the brain is obstructed by blood clots or clogged arteries. Hemorrhagic strokes, on the other hand, are caused when blood vessels rupture.)

The researchers used their tool to calculate "Z scores" measuring the severity of metabolic syndrome among the study participants. They could then analyze the association between metabolic syndrome and ischemic stroke risk.

The subgroup with the highest association between metabolic syndrome and risk for ischemic stroke was white women, the researchers found. In this group, the research team was able to identify relationships between the individual contributors to metabolic syndrome, such as high blood pressure, and stroke risk.

The researchers note that race and sex did not seem to make a major difference in stroke risk overall, and they caution that the increased risk seen in white women could be the results of chance alone. "Nevertheless," they write in a new scientific article outlining their findings, "these results are notable enough that they may warrant further study into race and sex differences."

'Good Cholesterol' to Gauge Heart Attack and Stroke Risk
HDL-C, the standard cholesterol test predicts heart attack risk in the general population, but not the risk of stroke. Therefore, analysis of HDL-P, which determines how many HDL particles circulate In the blood, is a better predictor of heart attack and stroke.

The overall relationship between metabolic syndrome severity and stroke risk was clear, however. And this suggests people with metabolic syndrome can make lifestyle changes to reduce that risk. Losing weight, exercising more, choosing healthy foods - all can help address metabolic syndrome and its harmful effects.

DeBoer hopes that the tool he and Gurka developed will help doctors guide patients as they seek to reduce their stroke risk and improve their health and well-being.

In case there are still individuals out there debating whether to start exercising or eating a healthier diet," DeBoer said, "this study provides another wake-up call to motivate us all toward lifestyle changes."
