An avid scuba diva, 43-year-old Suzanne weeks could easily carry 65 pounds of gear.

"You do need to be fit and able carry that weight about 200 yards and swim 200 yards,” says Weeks.

She ate healthy too.

"I have been a vegetarian before my heart attack,” says Weeks.

And longevity runs in her family. So, Suzanne never thought she'd have a heart attack, until..

"I began having symptoms of jaw pain, numbness and tingling down both arms--I didn't feel quite right. I had a bit of chest pain, but not excruciating."

She looked healthy, even while in the ER.

"It probably about 2 hours before I was diagnosed with a heart attack."

Dr. Ermina Guarneri, cardiologist and founder of the Scripps Center for Integrative Medicine says protecting your heart takes more than good cholesterol levels.

"It's about stress, and lifestyle... are you living a stressed life, a depressed life, are you exercising everyday.. so there's lots of pieces to the puzzles when we look at why someone has a heart attack,” says Dr. Guarneri.

Suzanne took her advice to heart.

"I added yoga, meditation, journalizing into my health and wellness program, “ says Weeks.

She's still scuba dives, and still a vegetarian. Only now, Suzanne does what cardiologist say is the key to a healthy heart.

"To make sure I get 30 minutes of cardio vascular exercise a day."
