Former President Bill Clinton was in New York City Wednesday, talking about the Alliance for a Healthier Generation, an organization that promotes heart health, nearly one week after he was recently hospitalized for heart complications.

The focus of the conference was fighting childhood obesity and the efforts that The Clinton Foundation and the American Heart Association have made at 7,800 schools in all 50 states to teach kids how to lead a healthier lifestyle.

Clinton joked with the crowd about his heart issues, saying, "It's a good time for me to be talking about [heart health] because everyone knows I went to the doctor last week for a little tune up on my heart."

Last week, Clinton underwent a procedure to unclog a blocked artery to his heart.
