What are the etiology and risk factors associated with this case?

Mrs. Sunshine, a 54-year-old African American woman, is traveling from Denver to Boston to see her son who is studying at UMASS Boston School of Nursing to be a family nurse practitioner.
He has not seen his mother since he left Denver 2 years ago. He has been quite busy with a new position and a new family besides taking an advanced pathophysiology course. Anyway, at the airport, he noticed that his mother was short of breath and looked very tired and anxious. When he asked whether she had chest pain, she denied chest pain but admitted that she did have some chest discomfort at the Denver airport. He knows that his mother has hypertension and has not been faithful about taking her medications. He called 911 and took his mother to the hospital directly, despite Mrs. Sunshine’s objections. She told him that she did have dyspnea and fatigue for the past week and she thinks that she might have the flu or perhaps it’s just the long trip that made her tired and caused some breathing problems.
