Heart health depends on a variety of factors including your overall health and level of activity, as well as what kind of exercise you do.  High-intensity aerobic exercise, such as running or cycling, can help you get your heart rate up and strengthen your heart muscle.  More recently, certain types of strength training, such as weightlifting, can help you also strengthen your heart muscle, and help you maintain your heart health as you age.  Staying active is also important to help you stay heart-healthy.
