These blood groups are threatened by heart attack

People with certain blood types are more likely to suffer from a heart attack during periods of pollution.

The blood type of people is directly linked to certain body functions. According to one study, the daily “Dalymail” shows that people who have blood types A, B, or AB have a high risk, compared to the type of O blood.

Scientists have shown that pollution is linked to an increased chance of a heart attack, but this is the first time the risk has also been linked to blood type.

Of course, blood type is genetic, it's not up to anybody, but those with blood types A, B and AB are at risk of being the most affected.

The reason, according to scientists, is because in these blood groups, it is the highest level of coagulating protein that prevents blood from reaching the vital organs.
