Exercise Training to Improve Cardiopulmonary Hemodynamics in Heart Failure Patients

Study Purpose

This research study is being done to find out if exercise therapy can help improve the heart function, overall health, and quality of life of patients with pulmonary hypertension caused by heart failure.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

The purpose of this research is to see if taking part in structured exercise training will improve the ability to exercise, the function of the heart, and the function of the blood vessels that supply the lungs in patients with heart failure and pulmonary hypertension. After enrollment all patients will complete exercise testing. Patients will be randomized to either 10 weeks of exercise training (3 times per week) or will continue standard medical care. All patients will undergo detailed exercise testing before and after the intervention.

Arms & Interventions


Experimental: Exercise Training

Two sets of exercise testing (before and after) 10 weeks of supervised exercise training (3 sessions per week) at Mayo Clinic Florida.

No Intervention: Control Groups

Two sets of exercise testing while continuing with standard medical care in between.


Other: - Exercise Training

10 weeks of supervised exercise training, 3 sessions per week at the cardiac rehab clinic at Mayo Clinic Florida.
