Taking control of your heart health is crucial to living a long, happy life. Like all aspects of your health, there are both genetic and environmental components. While genes may increase the risk of a condition, most of the time there needs to be a lifestyle component which actually makes you have that condition. Even if you have genes which increase the risk of a heart attack, by making key lifestyle changes such as adopting a Mediterranean diet or exercising you may be able to prevent a heart attack from actually occurring.
