Blood Pressure Changes During Moderate Intensity Strength Training in Aortic Stent-graft Patients

Patients with an aortic stent graft are recommended to do muscle strengthening exercise as part of their rehabilitation. But, as excess blood pressure pose a risk to the integrity of the stent graft, high intensity muscle strengthening exercise may potentially be detrimental, and hence moderate intensity muscle strengthening is recommended. However, the blood pressure changes during moderate intensity strengthening exercises are unknown, and this study aims to quantify these among patients and compare them to those of healthy volunteers.

Purpose:

The purpose of this study is to investigate the increase in blood pressure during quadriceps muscle strength training in patients with aortic stent graft.

Methods:

Patients with aortic stent graft will be included. The participants are investigated once. During the investigation, the blood pressure increase during a single strength training exercise (leg press) is measured. The strength training exercise is done at 60% of maximal strength (moderate intensity) corresponding to 15 Repitition Maximum (RM) (a load that can be lifted exactly 15 times).

Treatment and study plan

Moderate Intensity Muscle Strengthening

Other

1 session of lower extremity muscle strengthening at moderate intensity (60% of estimated maximal muscle strength). The exercise is performed on one single day.

  1. Peak systolic pressure during a single lower extremity muscle strengthening exercise

    Time frame: 5 minutes: 15 repetitions of leg press muscle strength exercise.

    Blood pressure is measured continuously using a finger clamp measurement device (Nexfin)
