Risk factors are the characteristics and habits that may increase your chances of having a heart attack or stroke. More factors mean a greater chance of developing problems. But the risk of having a heart attack can be reduced.

A good start to reducing your risks is to become aware of your risk factors. The next step is to reduce those factors that you can change or control.

To learn about your own risk factors, take the Central Maine Heart and Vascular Institute's Quick Quiz.
