The risk of heart disease and other heart problems can be minimized by making lifestyle changes. Your diet, for instance, has an incredible effect on the health of your heart. Physical activity can keep your heart muscles in tip-top shape, just like it could any other muscle of your body. And not to get sappy on you, but even happiness can help - it actually decreases your heart disease risk as you age.

Even if you do everything in your power to prevent heart problems, they could still happen. Everyone is at risk - though some more than others - so knowing the signs and symptoms of an oncoming problem is crucial.
