After Elizabeth Banks premiered her short film “Just a Little Heart Attack” at an American Heart Association/Go Red for Women event Tuesday night, guests were shocked when an attendee collapsed of her own apparent heart scare. When the woman fainted while clutching her chest at Abe & Arthur’s, witnesses tell Page Six that guest Star Jones leaped into action to call 911 and Dr. Suzanne Steinbaum, a cardiologist from Lenox Hill Hospital who had just walked into the event, tended to the victim. A rep for the event said, “There was a lady who didn’t feel well. Paramedics checked her out on-site, but she was fine.”
