Genetic difference in blood clotting may underlie racial health disparity

Statistically, black people are less likely to survive heart attacks than white people.  This is generally due to social and cultural factors; however, genes may play a significant role as well.  Black people were found to have an increased ability for blood clotting.  A significantly higher amount of microRNA's were found in the blood of black subjects than in white subjects.

Race should be taken into account when making anti-thrombotic drugs, but will drug companies deem it worth researching drugs that are specific to a minority population?  As a result, the factors that contribute to the reduced chance of black people to survive heart attacks are essentially social.  Also, are microRNA's linked with sickle-cell anemia, another disease that is common in black people?  Until drugs and other treatments become more tailored to minority groups, it is best that one do research and  take preventative measures to hopefully reduce the likely-hood of developing whatever illness to which  one might be predisposed.
