Study into myocardial stunning during haemodialysis and the effect of biofeedback haemodialysis

INTERVENTION: We propose to study chronic haemodialysis patients in a randomised crossover study. The first group will undergo an initial period of standard haemodialysis followed by a period of biofeedback‐controlled haemodialysis. The second group will do the same in reverse. At the end of both periods, all patients will undergo echocardiography performed at regular intervals throughout a single haemodialysis session, and for a short period afterwards. They will also have Troponin T measured before and after the same dialysis session. CONDITION: Urological and Genital Diseases: Haemodialysis ; Urological and Genital Diseases ; Haemodialysis PRIMARY OUTCOME: 1. Number of regional wall abnormalities/patient; 2. Ejection and shortening fractions SECONDARY OUTCOME: Not provided at time of registration INCLUSION CRITERIA: Patients on chronic haemodialysis
