is heart problems mostly genetic
They found, in addition to the 10 previously known gene regions for CAD, 13 new gene regions. The findings were unexpected. “The majority reside in gene regions that were not previously suspected in the pathogenesis of CAD,” the researchers write. Genetics play a major role in the development of heart disease. Identifying genes that put people at increased risk could aid in the development of both prevention strategies and new treatments. But first, more study is needed to determine how the genes contribute to CAD.
Inherited heart conditions are caused by a fault (or mutation) in one of more of our genes. If one of your parents has a faulty gene, there’s a 50:50 chance you could inherit it. If you do, then there’s also a 50:50 chance you could pass it on to each of your children.
