Primary Outcome Measures

Name	Time	Method
<br>Outcome name:Automated blood pressure measurements will be carried out with an Omron blood pressure monitor. The arm with the highest reading of diastolic blood pressure will be used. The patient should be in a relaxed context and measurements should not be taken immediately after making an effort or consuming coffee. After the patient has been sitting for five minutes with the back supported and both feet on the floor, the diastolic and systolic blood pressure will be determined three times.<br>Measure:1) Change with respect to the initial value in MSDBP. 2) Change with respect to the initial value in MSSBP.<br>Timepoints:8 weeks.<br>
