Our Bloody group He speaks much more about us than who can sacrifice blood or if we are really the children of our parents. For example, it was noticed that people with blood A or B type B may be more likely to develop cardiovascular conditions, although the type may suffer from more hemorrhages. There are also some studies that suggest that some blood groups may be more vulnerable to covid-19 than others, although there is no sufficient evidence. And, without a doubt, one of those who study this topic, which attracted the greatest attention in recent years, is the one who It connects a stroke with a blood type A1.
Blood type A1, as the name, This is a subgroup of group A. In 2022, a team of scientists from the University of Maryland considered the total number 48 Genetic studiesIn which more than 600,000 people were included between 18 and 59 years. Some preliminary studies have shown that blood type may relate to strokes in People under the age of 60. That is why they chose this sample. And the truth is that, according to its results, this may be true.
They noticed that people with a blood type A1 had a slightly higher risk suffer from a stroke to 60 years. Nevertheless, the risk of people with a blood group A is not huge compared to the total number, so the authors of the investigation do not believe that it is necessary to do follow upIn addition, a correlation was found, but not a reason, therefore it cannot be excluded that all the coincidence. In science, finding causes is always very important. As an example, there is nothing more to see about autism and paracetamole, which was recently deleted by Donald Trump.
What depends on the blood type?
A human blood type is determined in accordance with antibodies that are faced with their Red blood cellsFor example, people with blood group B have in their body Anti-A-Antitiae, Thus, he attacks red blood cells with an antigen of type A., on the other hand, people with a blood group A have Anti-B antibodieswho is faced with antigens like B. For their part, people with blood type 0 both anti -AA, and anti -B -antibodiesBut they do not have this antigen in their red blood cells, so they do not suffer from an immune attack.
Each blood group can also have subgroups. For example, in group A two of the most famous A1 and A2The A1 field, which is the one that corresponds to us in this article, is characterized by the fact that it is subject to attacking more specific antibodies called anti – -A1.
What does all this have to do with strokes?
The presence of antigens of one type or another and, therefore, susceptibility to some antibodies or others depends on the series Concrete genes that are expressed in red blood cells. These genes also, according to, have a certain relationship in strokes, in accordance with what was noticed in this study.
They took Data 17,000 people This suffered a stroke, but 600,000 – no. When analyzing genes that are expressed in their blood cells, they really saw that he had antigen gene A1 The probability is 16 % more than the rest of the stroke up to 60 years.
On the other hand, they saw that those who had a general associated with the O1 group had 12 % lower risk.
Why all this?
The reasons for this correlation are unknown, although there are some hypotheses. The authors of this study indicated at that time that this could be a question Blood coagulation factorsFor example, it would be a case of platelets and cells that cover blood vessels. Although this may also be associated with other circulating proteins involved in Development of clots.
To learn more, these scientists hope to repeat the study with a large number of participants, from a more diverse countries and ethnic groups. This would give much more interesting information. At the moment, nothing has been published. Despite all this, panic should not spread among people with a blood group A. From the very beginning they do not know whether they are group A1, and even if they were the probability that the total amount would be significant, but low. All this is if these scientists have seen Something more than a simple chance.
