Which blood type is most vulnerable to an early stroke?

According to experts at the University of Maryland School of Medicine who have completed a meta-analysis of 48 studies that have been published so far on the topic, stroke occurs more frequently in people with blood type A and less frequently in people with blood type 0 before the age of sixty.

Blood type connected to early stroke.

Researchers found that individuals with blood type A are 18% more likely than those with other blood types to get an early ischemic stroke. Similar strokes occur 14% more often in blood type 0 individuals before the age of 60. fewer times than for blood types of other types.

There was a somewhat different connection observed in those with blood group B. Both early strokes, which are typical of younger people, and late strokes, which happen later in life, were more common in them than in the control group. The journal Neurology has published comprehensive findings of the meta-analysis performed by researchers at the University of Maryland School of Medicine.

Blood group and stroke. Who is most at risk?


The study used information from 570 thousand healthy individuals and 17,000 stroke sufferers. 35% of participants were from countries outside of Europe (including Japan, Pakistan, Australia and the United States). It was emphasised that the acquired results might not be uniform across ethnic groups after accounting for gender and other characteristics.

The research team’s leader, Prof. Braxton Mitchell, a medical professional at the University of Maryland School of Medicine, thinks that individuals with blood type A may be more susceptible to blood clots, which explains why early ischemic strokes are somewhat more common in this population. Scientists have not, however, been able to definitively identify the sources of this occurrence or establish why.

“We still don’t know why blood group A is associated with a higher risk of stroke, but it likely has something to do with blood clotting factors such as platelets and cells that line blood vessels, as well as other proteins that play a role in blood clots.”

    85% of all stroke cases are ischemic strokes, which are the most frequent type. every stroke. When blood flow is obstructed, they take place. They appear unexpectedly.

Balance issues, unilateral limb weakness, double vision (overlapping pictures), a drooping corner of the mouth, speech impairments, trouble swallowing, disorientation, and altered consciousness are some of the earliest symptoms. Women are more prone to develop headache, weakness in the arms, palpitations, shortness of breath, hiccups, and chest pain. There may occasionally be nausea, vomiting, or agitation.

This is one of the quickest ways to identify the signs of a stroke. the FAST test, which has long been advised by medical professionals and paramedics.
