Marcus Neuroscience Institute Stroke Expert Comments on New Study Linking Stroke Risk to Blood Type

As the number of people who suffer a stroke at a young age continues to rise, new research suggests a correlation between blood type and risk of what doctors call “early stroke.” Experts at the Marcus Neuroscience Institute, set up at Boca Raton Regional Hospital, part of Baptist Health, say the study is “very interesting” and opens the door for further research into exactly how one’s blood type determines an elevated one Risk of stroke may predispose before age 60

The study recently published in the journal neurologyfound that compared to people with late-stage stroke and people who have never had a stroke, people with early-onset stroke were 16 percent more likely to have type A blood and 12 percent less likely to have type O blood, the most common blood type.

These people, according to the study, “are more likely to die from a life-threatening stroke event,” and those who survive may face decades of disability. In addition, the study found that both early and late stroke patients were more likely to have type B blood compared to control groups.

The researchers emphasized that the increased risk is “very small” and that people with blood type A “should not worry about having an early-onset stroke or engage in additional screening or medical testing based on this finding.”

Cardiovascular disease and stroke are two of the leading causes of death and disability in the United States, according to neurosurgeon Brian Snelling, MD, director of cerebrovascular and endovascular neurosurgery and director of the stroke program at the Marcus Neuroscience Institute.

When blood flow to the brain becomes obstructed, it can lead to an ischemic stroke, says Dr. Snelling, and there are usually two ways that can happen. “People with abnormal heart rhythms, such as atrial fibrillation, can develop blood clots in the heart. If a clot were to travel to the brain – an organ that needs a lot of blood to carry out its many functions – it could easily cause a stroke,” he explains. “Or plaque can build up in the carotid artery in the neck, and if it were to rupture, that too could create a clot and trigger an ischemic stroke.”

More research needed

If there really is a group of people with an increased risk of stroke because of their blood type, the challenge, according to Dr. Snelling is figuring out how to mitigate their risk. “This requires a better understanding at the cellular level of how blood type can affect early stroke risk,” he says. “More research is needed to understand the mechanisms of action.”

In the meantime, people with blood type A who fear they may be at increased risk of early stroke are encouraged to make lifestyle changes that may reduce those risks, says Dr. Snelling adding that he has type A blood but isn’t. I am anxious. “That would include the standard recommendations of maintaining a healthy weight, eating a healthy diet, exercising regularly, limiting alcohol consumption and eliminating smoking,” says Dr. quicking “But these are things that you should definitely do, regardless of your blood type.”

If you think you or someone you are with is going to have a stroke, says Dr. Snelling to call 9-1-1 immediately. “Of course, where you are taken depends on where you live, but the Marcus Neuroscience Institute is a certified comprehensive stroke center, which means we have the staff, procedures and technology necessary to provide stroke patients with the best possible care to be able to He says. “Our clinical facilities, including our state-of-the-art operating rooms and neurointerventional radiology suites, are the best in the region and allow us to quickly diagnose and treat stroke or other types of neurovascular disease.”

dr Snelling says another benefit of the Marcus Neuroscience Institute is that it can connect patients to clinical trials exploring the latest and most advanced therapies. “We are actively enrolling patients in clinical trials — trials that not only have the potential to save lives but also advance our knowledge of stroke and its treatment,” he says.
