About this trial
This study is being completed because there is conflicting information regarding the value of monitored exercise in patients with heart failure with preserved ejection fraction (HFpEF). The purpose of this study is to collect baseline information necessary for researchers to pursue a larger study evaluating how monitored exercise performed during cardiac rehabilitation may improve heart health and the amount of oxygen delivered to the tissues during exercise. Researchers must first examine whether the facility is capable of supporting such a study and whether in a modest number of patients, there is no clear detrimental effect to exercise. Rather, there may be an important improvement that has been underestimated to date.
Participation will require a time commitment for performing exercise 3 times per week for 12 weeks in addition to having a small amount of blood drawn twice. There will also be a specialized form of a stress test (cardiopulmonary exercise test; "CPET") with ultrasound imaging of the heart (echocardiography) completed twice.

Trial groups
Trial outcomes
Primary outcomes
Cardiorespiratory Fitness (CRF)
Change in cardiorespiratory fitness response (\>10% increase in oxygen consumption on cardiopulmonary exercise testing).
Secondary outcomes
Change in Kansas City Cardiomyopathy Questionnaire 12 total score
Change in symptoms will be determined by assessing the difference in Kansas City Cardiomyopathy Questionnaire 12 total scores between baseline and exercise training program completion. The total score ranges from 0 to 100 with higher scores indicating better health and symptom status.
Change in 6 Minute Walk Distance (feet)
Change in physical functioning using the 6-minute walk test. The change in 6 minute walking distance is expressed as an absolute value with longer distances indicating better health and physical functioning.
Exercise capacity
Change in exercise capacity in metabolic equivalents
Myocardial stiffness
Change in LV myocardial and chamber stiffness by tissue doppler echocardiography
