Randi is a 42 year old waitress. She was vacuuming the family room when she felt a painful squeezing in her chest. This was the third time today, but this time it really hurt. She sat down to catch her breath and put out the cigarette she currently had sitting in the ashtray. At her last appointment, Randi's blood pressure was 158/88, which she attributed to the stress at work. Her cholesterol was 30 points above average but was coming down due to diet changes.

The pain started again and moved up into both sides of her jaw and she thought maybe it was heartburn since the pain didn't radiate down her left arm.
