Imagine a hospital room in the cardiac unit, with a patient, her family, doctors and nurses, all discussing the patient’s status and treatment options. So who are the experts in the room? Are they the doctors and nurses who have studied, practiced and devoted their lives to understanding and treating cardiac diseases? Are they the family members who can read the patient’s face and body language and know what the patient is too scared to ask herself? Is it the patient, who, after all, is the only one who really knows what her body feels like?
