2. Studies About Heart Attack and Blood Type
In the 2017 study, researchers stated that non-blood group carriers had “greater concentrations of von Willebrand factor, a blood-clotting protein which has been associated with thrombotic events.”
Stephen Kimmel, MD, MSCE, director of Cardiovascular Epidemiology in the Department of Medicine at Penn and Center for Clinical Epidemiology and Biostatistics, and senior author on the ASH abstract stated about the 2017 study, “The Framingham study has a lot of advantages: it’s large, and it has a long follow-up period – 38 years.”
He went on to say, “It has incredibly rich information about other cardiac risk factors, factors that one would want to examine to ensure the effects of a blood group if there was one, were independent of additional cardiac risk factors.”
There are perhaps other things that need to be further explored about how blood group alters propensity for cardiac disease. Or, maybe with a better understanding of a biomarker related to the mechanism, that might be a more powerful method of predicting future cardiovascular events.
Findings from the 2021 study published in January also shared the same theory about non-O blood types being at higher risk of a heart attack. In fact, the study showed that people with type A and type B blood had a 44 percent chance of developing thrombosis, which is the formation of blood clots.
1. Blood Type in America
Without a doubt, blood type O is the most common type of blood in the US. Those with type O blood type include:
- 45 percent of whites
- 51 percent of African Americans
- 57 percent of Hispanics
- 40 percent of Asians
Of all the blood types, AB is extremely rare, with only 4 percent of whites and African Americans having this type. Two percent of Hispanics and 7 percent of Asians have this unusual blood type.
In the analysis, their study found that.
- 23 percent of people with AB blood type develop heart disease (this could be due to the relationship between blood type AB and inflammation)
- 5 percent with type A have a risk of a heart attack
- 11 percent of people with type B have a risk of a cardiac event
