Some studies have identified specific genes known to increase a person's risk of heart disease. For example, WebMD reported on a study that identified six gene variants that were more likely to occur in people who had heart attacks or heart disease. However, this study was conducted with white Europeans, and people of other races or from other geographic locations may have other genetic risk factors.
