Brief Summary:
24 h blood pressure monitoring can help to define which is the optimal timing and frequency of measurements

Condition or disease Intervention/treatment
Arterial Hypertension Diagnostic Test: 24 h ambulatory blood pressure measurements

Detailed Description:
Hypertension is a common condition in modern society. As blood pressure fluctuates with time, a single blood pressure measurement is useless to diagnose hypertension. Nevertheless, a questionable not well-defined number of measurements still is often used for this purpose. Diagnosis and therapeutic control of hypertension are therefore suboptimal. This study's objective is to determine the number and timing of measurements needed to give a trustworthy approximation of an individual's average blood pressure. Therefore, 24 h ambulatory blood pressure measurements were retrospectively analyzed.

Group/Cohort Intervention/treatment
persons with arterial hypertension
patients referred to consultation cardiology for hypertension. They get a 24 h blood pressure monitoring to define the exact mean arterial blood pressure
Diagnostic Test: 24 h ambulatory blood pressure measurements
24 h ambulatory blood pressure measurements : an ambulatory 24 h blood pressure device that automatically measures blood pressure every 15 minutes is given to the patient for 24 h

Primary Outcome Measures :
  1. Timing of measurement [ Time Frame: day 1 ]
    9:00-13:00 - 13:00-17:00 - 17:00 - 21:00: there intervals were analyzed to assess the predictive value of each interval compared with the overall daytime diagnosis of hypertension.

Secondary Outcome Measures :
  1. The correct number of measurements [ Time Frame: day 1 ]
    Within the intervals, the correct number of measurements needed to diagnose hypertension will be evaluated.
