People with chest pain and trouble breathing need to see a doctor within minutes to determine whether the issue is life threatening. But a 25 year old Milwaukee woman suffering from an enlarged heart waited in an emergency room for three hours with these symptoms, before finally giving up.

She was beyond saving by the time an ambulance arrived. More details here.
