Acute Effects of Intradialytic Exercise on Cardiovascular Function in Hemodialysis Patients (ACE-HD)

5. marts 2017 opdateret af: Kenneth Wilund, University of Illinois at Urbana-Champaign
The purpose of this study is to examine the effect of cycling at mild to moderate intensity during hemodialysis treatment on cardiovascular function in a crossover design.

Detaljeret beskrivelse

Patients with kidney failure requiring hemodialysis (HD) treatment die at excessively high rates, despite advances in HD techniques and pharmacological therapies. This indicates additional therapeutic strategies are needed. Intradialytic exercise (IDEX, exercise during HD treatment) represents a low-cost, easy to administer treatment strategy that could potentially improve cardiovascular function, physical function and quality of life. However, nephrologists rarely counsel their patients to increase their physical activity levels or to exercise during HD treatment, in part due to a lack of understanding of IDEX knowledge.

Providing more robust evidence for the safety and effectiveness of IDEX, as well as evaluating the impact of exercising early vs late in the treatment, could help improve adoption of exercise training as a standard practice in HD clinics.

Therefore, investigators plan to examine the impact of IDEX and its timing during treatment (1st vs 3rd hour) on blood pressure and adverse symptoms in HD patients. The proposed study also includes various cardiovascular measures to allow deeper mechanistic understanding of cardiovascular physiology with IDEX. Such understanding will significantly advance the field and lead to improved therapeutic approaches, including exercise training, which may help mediate the deleterious effects of renal failure.

Changes in total peripheral resistance estimated by peripheral blood pressure via a finger plethysmography and cardiac output via thoracic impedance (Task Force Monitor)
Tidsramme: Continuous throughout each dialysis treatment (approximately 4 hours) for three dialysis sessions that are separated by a week
A finger cuff will be placed around the non-dialyzing finger and will measure the change in peripheral blood pressure from successive beats continuously. Total peripheral resistance will be estimated using measured cardiac output and peripheral blood pressure.
Continuous throughout each dialysis treatment (approximately 4 hours) for three dialysis sessions that are separated by a week
Hypotensive event assessment measured by a symptom questionnaire
Tidsramme: Throughout and up to 5 hours after completion of a dialysis treatment
The presence of hypotensive-relating intradialytic symptoms including nausea, dizziness and cramping will be recorded.
Throughout and up to 5 hours after completion of a dialysis treatment
