ClinicalTrials.gov Identifier:
NCT00325832
First received: May 12, 2006
Last updated: August 20, 2010
Last verified: May 2008
  Purpose

To determine if the use of automated office blood pressure readings can improve management of systolic hypertension in routine clinical practice. Automated office SBP recordings in routine clinical practice using the BpTRU device will reflect more accurately the mean awake ambulatory systolic BP than will manual BP readings taken with conventional mercury sphygmomanometry. This should lead to improvements in the management of systolic hypertension with optimization of drug therapy in practices using the BpTRU device.

  Eligibility

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Both treated and untreated patients with systolic hypertension under routine FP care
  • For untreated patients, routine office SBP as measured by the patient's FP at the last routine office visit using a mercury device must have SBP ≥ 160 mmHg and DBP <= 95 mmHg
  • For patients already receiving antihypertensive therapy, the last routine office BP as measured by the patient's FP using mercury sphygmomanometry must be SBP ≥ 140 mmHg and DBP <= 90 mmHg

Exclusion Criteria:

  • Presence of target organ damage such as MI, stroke, and serum creatinine twice normal
  • Diabetes mellitus treated with insulin or oral hypoglycemic therapy
  • Secondary hypertension
  • Participation in another research study involving measurement of BP
  • Patient's insistence on using self BP measurement outside of the study
  • Any conditions or circumstances which might preclude the successful completion of the study
