7 surprising signs of an unhealthy heart
We've all read the signs of a heart attack listed on posters in the hospital waiting room. But what if there were other, earlier signs that could alert you ahead of time that your heart was in trouble?

"The heart, together with the arteries that feed it, is one big muscle, and when it starts to fail the symptoms can show up in many parts of the body," says cardiologist Jonathan Goldstein of Saint Michael's Medical Center in Newark, New Jersey. Here are seven surprising clues that your heart needs a check. Any of these signs -- and particularly two or more together -- should send you to the doctor for tests.
