Summary

This trial is testing a time-efficient lifestyle intervention to lower blood pressure in people with chronic kidney disease and high blood pressure.

Who is the study for?

Adults over 50 with moderate-to-severe chronic kidney disease and high blood pressure that's not well-controlled, despite being on stable medication for at least 6 weeks. Participants should be non-smokers, not have had recent hospitalizations or severe heart failure, and cannot be using immunosuppressants or have significant lung diseases.

What is being tested?

The trial is testing whether a type of breathing exercise called high-resistance inspiratory muscle strength training (IMST) can lower blood pressure and improve blood vessel function in older adults with kidney disease. It compares IMST to a sham training to see if it's effective.

What are the potential side effects?

Potential side effects are not explicitly listed but may include discomfort from the breathing exercises or issues related to the use of equipment for those with certain pre-existing conditions like ear problems.
