People with type O blood are the least likely to suffer from cardiovascular issues
If you have type O blood, then your heart is in luck: According to research presented at the 2017 World Congress on Acute Heart Failure, individuals with this blood type are less likely to suffer a heart attack or stroke.
The bad news? Individuals who are type A, type B, or type AB—in other words, some 63 percent of the overall population—have a 9 percent increased risk of both coronary and cardiovascular events.
