Hypertension case study # 3

Mr Brown a 62-year-old African American man with “very labile blood pressure” (BP) for at least 11 years presents to his primary care provider’s office with the chief complaint of having “flunked” an insurance physical. Immediately after retirement (last month), he applied for a supplemental life insurance policy but last week he learned that his application was refused. He feels well and has no complaints. He says that his BPs have run “high” in the last 10 to 15 years, but always settle down when he rests for 10 minutes. He suspects that part of the reason for his denial of insurance was his BP, which was measured in his office by the physician assistant who performed his insurance physical as 148/98 mm Hg. He remembers that this measurement came in the middle of a very busy day, with 3 conference calls and a very stressful “exit interview” for one of his subordinates. He has been taking his BPs at home for the last week, and brings a printout of the last 15 readings; the average is 151.2/90.4 mm Hg, but the range is 130/72 to 160/102 mm Hg. He says he has not visited a physician for the last 10 years or so, because he’s been so busy with his work and his family. He brings copies of documents describing the results of the insurance physical that he had 2 weeks ago: abnormalities included a seated BP of 155/95 mm Hg, a glucose (allegedly fasting) of 156 mg/dL, a serum creatinine of 1.5 mg/dL, a (random) urinary albumin/creatinine ratio of 954 mcg/g, and an A1c of 7.8%. He was, of course, told to “discuss these results with his physician.” He recalls being denied a supplemental disability insurance policy about 6 years ago, allegedly based on “protein in my urine,” but didn’t follow up this abnormality. He denies previous treatment for hypertension or diabetes. He denies prior episodes of hypokalemia, muscle cramps, palpitations, headache, sweating attacks, visual disturbances, polyuria, polydipsia, and fevers.
