Cardiac Rehabilitation & Metabolomics in Heart Failure

Status Completed

Clinical Trial Summary

This is a randomized controlled trial of participants with heart failure randomized into usual care plus integrated cardiac rehabilitation or usual care only. The rehabilitation protocol will comprise one month of thrice weekly sessions including supervised aerobic exercises and counseling, followed by two months of monitored home based exercises prescribed weekly.

Cardiopulmonary performance status, depression and quality of life will be assessed at enrollment and upon completion of the protocol using the 6-minute walk time distance test. Plasma samples will be collected and bio-banked for metabolomic profiling and comparative outcome analysis.

Clinical Trial Description

Integrated cardiac rehabilitation will comprise one month of thrice weekly sessions of supervised aerobic exercises and counseling, followed by two months of monitored home based exercises prescribed weekly.

Aerobic threshold (AT) will be determined based on perceived rates of exertion as measured using a Borg scale and target heart rate based on Karvonen's formula. Exercise intensity will be prescribed to achieve the earlier of moderate perceived exertion and 50-60% of their maximal target heart rate on a treadmill. Intensity will be increased over the course of the 12 sessions to attain 70-80% of maximal target heart rate. Duration of exercise will also be increased gradually over the 12 sessions in keeping with the study participants perceived rate of exertion.

Participants will be given pedometers and instructed to use these daily for the period of the study. At the end of the first four weeks, the participant's weekly steps will be averaged to establish a baseline weekly step target. Starting in the 4th week,subjects will be instructed to continue exercises at home whilst maintaining a comparable activity level as will be measured by their weekly step counts. Participants will be contacted weekly for the remaining 8 weeks and step targets will be prescribed based on 10% weekly increments.Prior to the start of each exercise session, participants will receive a brief counseling module reflecting the primary goals of cardiac rehabilitation. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
