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.
