Chapter 15, Special Considerations for Metabolic Syndrome, Hypertension, and Dyslipidemia

The patient is a 53-year-old Hispanic female who runs a successful business from home. Her job is extremely stressful and requires working long hours. She has known hyperlipidemia and has been taking a daily multivitamin and Crestor (rosuvastatin) 10 mg daily for the past 5 years. She is a previous smoker (one pack per day for 20 years) but quit around the same time she was diagnosed with hyperlipidemia. Several years have lapsed since she has gone to the doctor, but at one of her church screenings, she was told that her blood pressure was “above optimal.” She went to her doctor, and on exam, she was 65 in tall and 249 lb, and her waist circumference was 50 in. Her blood pressure and heart rate were 144/72 mm Hg and 74 bpm, respectively. Her blood lipids were within normal ranges; however, her HbA1c was elevated to 7.4%. Although her physician was concerned about her blood pressure, she was most concerned with this sudden onset of weight gain and diabetes since she quit smoking. The physician notes that the patient has something called the “metabolic syndrome” and writes a prescription for her to start taking glipizide and HCTZ to get her blood sugar and blood pressure under control. The patient leaves the office feeling shocked and saddened by this diagnosis but decides that she is going to make some lifestyle changes as she has a new granddaughter on the way.

She now presents to your facility for a supervised exercise program with no history exercising with the exception of “playing table tennis at her family picnic once a year.” She denies any symptoms suggestive of cardiovascular, metabolic, or renal disease.

Case Study Questions

1.   According to current ACSM guidelines for preparticipation health screening, does the patient require medical clearance prior to beginning an exercise program?

2.   Based on what the patient has told you, what exercise prescription guidelines should be most closely followed and why?

3.   List the medications that the patient takes daily and determine how they may adversely interact with an exercise training program.
