Identify how the steps in the S$.$H$.$A$.$D$.$E process are illustrated in the following case: Dianne, a $30-$year$-$old part$-$time receptionist, has been experiencing chest pains in the center of her chest for more than $2$ months. The discomfort lasts from $5$ to $10$ minutes. These pains seem to occur after dinner if she lies down but not with exercise or at work. Dianne is concerned about whether these are due to her heart because her father died of a heart attack at age $62.$ She also worries because she is a bit overweight, being $5^{\text{'}}{4}^{\text{'}\text{'}}$ and $170$ pounds, and does not exercise regularly.

After asking about the exact location, timing, and frequency of her symptoms and determining that Dianne has not been a cigarette smoker, her doctor did a physical examination. The doctor examined Dianne's heart, stomach, and lungs; took her blood pressure; and did not find any abnormalities. Finally, the doctor checked Dianne's previous records and found that her LDL$,$ or bad cholesterol level, was within the normal range.
