Why your blood type can predict your stroke risk: Type As, you are 16% more likely to have a stroke –

Research suggests that a person’s blood type may be linked to their risk of early stroke.

US researchers looked at dozens of studies on genetics and ischemic stroke, the most common type.

They found that people with blood type A were 16% more likely than anyone else to have blood type before age 60.

The link persisted even after filtering out other risk factors such as gender, weight, and smoking.

People with type B blood had a slightly higher risk of stroke, but the risk was lower for people with the more common type O.

The increased risk, even for the As type, is modest and people shouldn’t worry, the researchers said.

It is unclear why blood type plays a role in stroke risk, but it is thought to affect a person’s risk of developing dangerous clots.

A person’s blood type may be linked to the type (file) most at risk of early stroke.

Ischemic strokes occur when a blood clot cuts off blood and oxygen to the brain, accounting for about nine out of 10 strokes.

Blood clots usually form in areas where arteries narrow over time or become clogged by fatty deposits known as plaques.

In the most recent study, a University of Maryland team analyzed data from 7,000 stroke patients and nearly 600,000 healthy people from 48 different studies.

They found that people with O blood were 12 percent less likely to have a stroke before age 60, while types B and AB had no effect.

The research, published in the journal Neurology, also found that about one in 16 strokes in people in the type A group could be attributed to blood alone.

Dr. “The number of people who have an early stroke is increasing,” said Steven Kittner, professor of neurology and co-researcher of the study.

“These people are more likely to die from the life-threatening event, and those who survive could be crippled for decades.”

“We still don’t know why blood type A poses a greater risk, but it probably has something to do with blood clotting factors such as platelets and the cells lining blood vessels.”

More than 91,000 strokes occurred in England, Wales and Northern Ireland in the 12 months between April 2021 and March 2022, according to official data.

About 800,000 people in the United States suffer a stroke each year.

Almost half of British and Americans have type O blood and a third of them are type A.

Type B and AB make up 10 percent and five percent, respectively.

Dr. Clare Jonas, president of the Stroke Association research communications and engagement, said the latest study is a “big step forward” in our understanding of genetic risk factors for stroke.

He told the Daily Telegraph: “We still don’t know why people with blood type A are at higher risk of early stroke.

‘This means we can’t yet develop targeted prevention for early stroke.

“However, this research is a big step forward in helping healthcare professionals understand who would most benefit from monitoring other risk factors and offering interventions to reduce risk.”

Everyone should take steps to monitor and manage their stroke risk. The most important thing you can do to reduce the risk of stroke is to monitor your blood pressure and maintain a healthy and active lifestyle.
