Detailed Description

Cardiovascular autonomic neuropathy is a common (sub)clinical symptom in persons with type 1 diabetes mellitus. Subjects in this non-commercial, monocentric, interventional study undergo autonomic function tests, a maximal ergospirometry and three questionnaires about the quality of life (EQ-5D-3L), the capacity to do physical activities (IPAQ) and the experience of possible symptoms of autonomic dysfunction in daily life (SCOPA-AUT). In this way the influence of type 1 diabetes mellitus on the quality of life, the exercise capacity and the autonomic function can be studied.

The primary aim of this study investigates the potential correlations between the severity of diabetic cardiovascular autonomic neuropathy (DCAN) and both the quality of life and the exercise capacity. As a secondary aim, the influences of gender, age, number of years since diagnosis of type 1 diabetes mellitus, VO2 max predicted, maximal heart rate during exercise, minimal heart rate in rest, maximal RER (Respiratory exchange ratio) and relevant interaction terms are studied.

In total 52 test subjects with type 1 diabetes mellitus and 27 matched control subjects are selected to participate in this study.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: subjects with Type 1 Diabetes mellitus
Type 1 diabetes patients without cardiovascular disease undergo autonomic function testing
Diagnostic test: autonomic function testing

autonomic function testing, ergospirometry, three questionnaires

Other Names:

  • The autonomic function tests consist of five tests:

    • The Valsalva maneuver
    • The isometric handgrip test
    • The deep breathing test

  • A maximal ergospirometry

  • Three questionnaires:

    • EQ-5D-3L: quality of life
    • IPAQ: capacity to do physical activities
Placebo Comparator: Healthy controls
healthy people without known disease undergo autonomic function testing
Diagnostic test: autonomic function testing
