title: Response of blood pressure to maximum exercise in hypertensive patients under different therapeutic programs.
abstract: OBJECTIVE
  To evaluate the behavior of blood pressure during exercise in patients with hypertension controlled by frontline antihypertension drugs.
  
  
  METHODS
  From 979ergometric tests we retrospectively selected 49 hypertensive patients (19 males). The age was 53+/-12 years old and normal range rest arterial pressure (< or = 140/90 mmHg) all on pharmacological monotherapy. There were 12 on beta blockers; 14 on calcium antagonists, 13 on diuretics and 10 on angiotensin converting enzyme inhibitor. Abnormal exercise behavior of blood pressure was diagnosed if anyone of the following criteria was detected: peak systolic pressure above 220 mmHg, raising of systolic pressure > or = 10 mmHg/MET; or increase of diastolic pressure greater than 15 mmHg.
  
  
  RESULTS
  Physiologic response of arterial blood pressure occurred in 50% of patients on beta blockers, the best one (p<0.05), in 36% and 31% on calcium antagonists and on diuretics, respectively, and in 20% on angiotensin converting enzyme inhibitor, the later the least one (p<0.05).
  
  
  CONCLUSIONS
  Beta-blockers were more effective than calcium antagonists, diuretics and angiotensin-converting enzyme inhibitors in controlling blood pressure during exercise, and angiotensin converting enzyme inhibitors the least effective drugs.
