Your Blood Type May Determine How Smog Affects Your Heart

"The primary mutation we studied differentiates between O blood types and non-O, which includes positive and negative A, B, and AB blood types".

According to Dr Horne, the risk for people with non-O blood types goes up by 25% for every 10 additional micrograms of PM2.5 particles per cubic metre, while the risk for people in the O blood group is 10%.

People with one blood type are at higher risk of air-pollution-related heart attacks if they already suffer with coronary heart disease, according to a new study.

The new study was created to build on and tie together those findings and test the influence of one variation, the impact of an individual's blood type.

Although the team cautions that a heart attack is never a certainty even with these factors and pre-existing coronary disease.

The study found that for every additional 10 micrograms over 20, the risk to people with type A, B, or AB blood increased by 25 per cent, but only by 10 per cent for people with type O.

The kind of blood you have could increase or decrease your risk of having a heart attack in response to high levels of air pollution, new research suggests.

"You have to have other characteristics for coronary disease to progress to a heart attack", Dr. Horne said.

Dozens of genes have been shown in large global studies to predict the onset of coronary artery disease in people who are free of the disease.

Air pollution could cause brittle bone disease, according to new research.

In the USA, 9 million men and have osteoporosis, leading to a bone fracture every three seconds, according to the International Osteoporosis Foundation.

The clinical data used for the study came from Intermountain Healthcare patients seen between 1993 and 2007.

Study co-author Professor Arden Pope, of Brigham Young University, provided the air pollution data.

The study was presented at the American Heart Association Scientific Sessions in California.

During a winter inversion, the PM2.5 pollution level can occasionally reach as high as 100 micrograms per cubic meter, but 50-60 is more typical.

Around 55 per cent of people are A, B, or AB and they are thought to be at greater risk of heart problems because their blood contains greater quantities of a clotting agent.

The World Health Organisation says exposure to PM2.5 pollution should not exceed 10 micrograms per cubic metre of air for it to be considered safe to breathe.

"In the information we provide to our patients about pollution, we try to stress that they can do something about it to reduce their risks", Horne says.

Dr Horne warns that people in A, B, or AB blood groups should consider staying indoors to minimise their risk if they already have underlying heart conditions, such as coronary artery disease.
