Study: genes play more of a role in heart disease cases than previously thought Unlisted Video

It's widely known that diet and lifestyle play a big part in developing coronary artery disease. The condition creates plaque buildup on artery walls, which can cause a heart attack or stroke when completely blocked. However, a new study shows genetics may play a bigger role in developing the disease than researchers thought. According to UPI, Swedish researchers now say that over 30 percent of heart disease cases are caused by genetic factors.
