A 58-year-old male smoker had had essential hypertension for about 15 years. It was well balanced with diuretics. He came for regular checks over the years. At such a check 3 months ago, his blood pressure was 195/110 mm Hg. With the addition of a beta-blocker and an angiotensin converting enzyme (ACE) inhibitor, it was possible to keep the pressure at around 180/100 mm Hg, thus it was not an optimal treatment result. Creatinine had increased over the last 3 months from 90 to 180–200 Rmol/l. The patient lived an active life and felt well.
