Ambulatory blood pressure monitoring. A tool for more comprehensive assessment.

AIMS
To investigate the usefulness of more comprehensive blood pressure measurements, made during daily life, in the diagnosis and treatment of hypertension.


METHODS
A blood pressure screening was carried out in middle-aged men and women in Kävlinge, a municipality in southern Sweden. Subjects were classified according to Swedish standard criteria. Ambulatory blood pressure (amb-BP) was recorded in a random sample of normotensives and borderline hypertensives as well as in all the untreated hypertensives identified at screening and willing to participate. A subgroup of borderline hypertensives also carried out self-measurements of blood pressure (self-BP) both at work and at home. The blood pressure lowering efficacy of atenolol 50 mg o.d. and enalapril 20 mg o.d. was compared in hypertensives at rest, during 24 hours, and during dynamic and isometric exercise. The efficacy of enalapril and lisinopril (two ACE inhibitors with different durations of action) were also compared, with special focus on the early morning hours.


RESULTS
Men and women classified as normotensives clearly differed from those with hypertension, also when blood pressure was recorded with ambulatory technique. The number of correctly classified subjects did not differ between self-BP and office-BP; combining the two added little. Atenolol reduced blood pressure better during dynamic exercise than did enalapril, while there was no significant difference in effect between enalapril and lisinopril, not even 18-24 hours post-dose.


CONCLUSION
More comprehensive blood pressure measurements should be considered in the evaluation of hypertension treatment. Office BP, however, seems a reasonably good tool for diagnosing hypertension.
