ClinConnect Summary
This clinical trial is looking at how two types of exercise—resistance (like lifting weights) and aerobic (like walking or cycling)—affect sudden drops in blood pressure during hemodialysis, which is a treatment for people with severe kidney disease. These sudden drops, called intradialytic hypotension, can cause discomfort and complications during dialysis sessions. The study aims to see which type of exercise might help improve heart and blood vessel health in patients who regularly receive hemodialysis.
People who might be eligible for this study are adults aged 45 to 60 who have end-stage kidney disease and have been on regular hemodialysis for between one and five years. They should have experienced these blood pressure drops during dialysis and have a body weight within a healthy range (not too high or low). Participants should be medically stable, not currently exercising regularly, and using a specific type of dialysis access in their arm. During the study, participants will be asked to perform either resistance or aerobic exercises during their dialysis sessions. It’s important to note that certain people, such as those with serious heart or lung problems, recent hospital stays, or who are pregnant, will not be able to join the study. This research has not started recruiting yet but aims to find better ways to support patients on dialysis through exercise.
