Sleepless nights may be doing more than leaving you fatigued the next day. They might also be increasing your risk of suffering a heart attack.

When it comes to a heart attack men and women display differing symptoms. The differences don't end there. Women may have more difficulty recovering after a heart attack and their quality of life may be worse.

A large population of seemingly healthy young adults appear to show discrete signs of heart disease even though they may not have any of the traditional risk factors for cardiovascular disease.

No one really believed that sitting on the sofa watching television was doing any favors for our fitness level. But instead could such sedentary activities be affecting our hearts?

Cardiac rehabilitation after a heart attack, surgery or for a heart condition can help patients live longer. This is especially true in the least fit patients --but they have to show up.

A patient's own stem cells may be the key to repairing the heart after a heart attack. Though the cells might be scarce, in a twist that sounds like science fiction, they can be grown using stem cells from umbilical cord blood.
