Glyceryl trinitrate (organic nitrate)

Mrs. Reed thanks you for your excellent care so far. She feels a lot better and is in good spirits, telling everyone about how excited she is about the arrival of her grandaughter, little Faith, in a few months. 

You take this opportunity to establish the events that led to acute exacerbation of her condition. Mrs. Reed tells you that she just came back from a family vacation. She admits that she did not adhere to her cardiologist's recommendations and probably overdid it with salty foods and alcohol over the past few days.
