About this study

Arteriograph24 is a new monitor for measuring ambulatory blood pressure and additional performing brachial cuff based on analysis of a suprasystolic pulse wave.

The study aim to test the feasibility of ambulatory pulse wave analysis every twenty minute (the fraction of missed measurements)and the reprodicility of pulse wave velocity and central augmentation index in type 2 diabetic patients. In addition we will explore the relation between diurnal variation of brachial blood pressure, central blood pressure and pulse wave velocity.

20 type 2 diabetic patients will have 24h ambulatory blood pressure performed twice with an interval of one week.

Treatment and study plan

Primary outcomes

  1. Fraction of missed pulse wave analysis

    Time frame: Meaured two times with an interval of one week

    Measurements of ambulatory blood pressure and pulse wave analysis is performed every twenty minute. The fraction of missed measurements of pulse wave analysis during day time and night time analysis is the final outcome

Secondary outcomes

  1. Reproducibility of pulse wave analysis parameters

    Time frame: Measured two times with an interval of one week

    Reproducibility of pulse wave velocity, Central systolic blood pressure and central augmentation index for 24 hour, day and night

Other outcomes

  1. Diurnal variation of brachial blood pressure, central blood pressure and pulse wave velocity

    Time frame: Measured two times with an interval of one week

    brachial blood pressure, central blood pressure and pulse wava velocity is measured evrey twenty minutes and averaged for day time and night time. the relative reduction at nioght for the parameters are calculated
