Your Blood Type May Show Risk Of Heart Attack From Pollution

Our blood group may be an indication of heart attack risk from air pollution. Those with blood type A, B, AB, A-, B-, or AB- may have a higher risk of having heart attacks amid times of critical pollution, than people that belong to O blood group, according to a new study.

The results revealed that when air pollution peak at 25 micrograms of air pollution per cubic meter, it amplifies the danger for individuals who belong to non-O blood groups. “Above that, an additional mark of 10 microgram per cubic meter air pollution gave significantly higher risks,” said the lead researcher Benjamin Horne, a epidemiologist in Utah, United States. “Any level above 25 micrograms of air pollution per cubic meter result to a linear increase in the risk of a heart attack, while anything below there is a little or no difference in risks.

Patients with type A, B and AB blood should not panic

In the investigation, the researchers examined the genetic differences that exist between type O blood and other blood types – which are the A, B, AB, A-, B-, and AB- blood groups. “The genetic experiments showed that type O blood had a lower risk, while non-O blood groups had higher risks,” Horne said. “Nonetheless, this link between the risk of suffering a heart attack and air pollution in people having non-O blood type shouldn’t cause panic. However, one should be educated,,” he said.

In addition, patients with O blood type also face the risk of suffering a heart attack and precarious chest pain during extreme air pollution. However, the risk is minimal at 10%, rather than the 25% of non-O blood type per 10 extra micrograms for each cubic meter, Horne said. When it gets to 65 micrograms of pollution, a patient with O blood type has a 40% risk than when the air was not polluted.

The findings were conferred at a 2017 medical conference held in California.. Some ways to reduce heart attack risks include staying indoors, regular indoor exercising, and taking heart medication, the scientists reported.
