According to recent studies, people with blood type A, AB and B are more likely to develop heart disease and a shorter life compared with people who have blood type O.

But it does not mean that people with blood type other than O should not worry, because the risk of heart disease and life span are also influenced by several factors, including exercise and overall body health.

In this study, the scientists collected data from about 50,000 middle-aged and elderly in northeast Iran, for an average of seven years. The results show that people who have blood other than O, 15 percent more likely to die from cardiovascular disease.
