Cardiovascular Diseases, Hemodialysis
Conditions
Brief summary
This study evaluates the use of remote ischaemic preconditioning for the prevention of dialysis induced cardiac injury. The study uses four arms to test different frequencies of application to ascertain which, if any, is most successful at reducing dialysis induced cardiac injury.
Interventions

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome will be a reduction in the number of left ventricular segments undergoing a greater than 30% reduction in longitudinal strain as detected by echocardiography at final study visit | 4 weeks |
Secondary
| Measure | Time frame |
|---|---|
| Number of segments undergoing >30% reduction in longitudinal strain at intervention, week 1, week 2 and week 3 visits | up to 3 weeks |
| Difference between pre and peak global longitudinal strain at intervention, week 1, week 2 and week 3 visits | up to 3 weeks |
| Change in pre-dialysis global longitudinal strain between baseline and final study visit | between 1 and 4 weeks |
| Change in Troponin-T, Plasma IL-6 and N-Type proBNP at intervention, first follow-up and final visit | up to 4 weeks |
