Heredity isn't always destiny when it comes to heart attacks: study

By Gene Emery (Reuters Health) – If heredity puts you at higher risk for a heart attack, maintaining a healthy lifestyle can bring that risk down dramatically, below the risk faced by some people whose genes would normally protect them from heart disease, according to a new analysis of more than 55,000 people. “We were a little surprised by how much you could offset your inherited risk by adhering to a healthy lifestyle,” said Dr. Sekar Kathiresan, chief author of the new study, presented at an American Heart Association meeting on Sunday and published online simultaneously by the New England Journal of Medicine. The 20 percent of the population with the highest genetic risk had a 5.1 percent chance of having a heart attack over 10 years if they practiced a healthy lifestyle.
