title: Drug treatment of hypertension in older persons in an academic hospital-based geriatrics practice.
abstract: OBJECTIVE
  To investigate the prevalence of hypertension in older persons, the prevalence of the different antihypertensive drugs used to treat hypertension, the prevalence of the different antihypertensive drugs used to treat hypertension in persons with prior myocardial infarction (MI) or congestive heart failure (CHF), and the prevalence of lowering the blood pressure to <140/90 mm Hg with therapy.
  
  
  METHODS
  A retrospective analysis of charts from all older patients seen from December 1, 1997, through August 31, 1998, at an academic, hospital-based geriatrics practice was performed to investigate the prevalence of hypertension in older persons, the prevalence of different antihypertensive drugs used to treat hypertension, the prevalence of different antihypertensive drugs used to treat hypertension in persons with prior MI or CHF, and the prevalence of lowering the blood pressure to <140/90 mm Hg with therapy.
  
  
  METHODS
  An academic hospital-based geriatrics practice staffed by fellows in a geriatrics training program and fulltime faculty geriatricians.
  
  
  METHODS
  A total of 459 men and 1360 women, mean age 80 +/- 8 years (range 59 to 101 years), were included in the study.
  
  
  RESULTS
  Hypertension was present in 1051 of the 1819 persons in the study (58%). Target organ damage, clinical cardiovascular disease, or diabetes mellitus was present in 738 (70%) of these 1051 persons. Of the 1051 persons with hypertension, 520 (49%) were treated with diuretics, 297 (28%) with beta-blockers, 445 (42%) with angiotensin-converting enzyme (ACE) inhibitors, 171 (16%) with calcium channel blockers, and 13 (1%) with other antihypertensive drugs; 41 (4%) received no antihypertensive therapy. The last blood pressure recorded on the chart was <140/90 mm Hg for 735 of the 1051 persons (70%) with hypertension. Of 306 persons with hypertension and prior MI, 182 (59%) were treated with beta-blockers, 146 (48%) with ACE inhibitors, 96 (31%) with diuretics, and 29 (9%) with calcium channel blockers. Of 103 persons with hypertension and CHF, 103 (100%) were treated with diuretics, 94 (91%) with ACE inhibitors, 22 (21%) with beta-blockers, and 3 (3%) with calcium channel blockers.
  
  
  CONCLUSIONS
  The prevalence of hypertension in the 1819 older persons seen in an academic, hospital-based geriatrics practice was 58%. Educational efforts led to increased use of diuretics and beta-blockers and decreased use of calcium channel blockers in treating hypertension. The last blood pressure recorded on the chart was <140/90 mm Hg in 70% of older persons with hypertension in the study.
