The goal of this research study is to understand whether an at-home exercise program started after hospitalization for HFpEF, and continuing for 4 weeks following discharge from the hospital, can preserve or improve physical function.
Heart failure is the leading cause of hospitalization among adults in the US with patients with preserved ejection fraction (HFpEF) comprising half of those admissions. Many patients exhibit chronic fatigue, exercise intolerance and an inability to perform activities of daily living, which is exacerbated by hospitalization. The goal of this research study is to understand whether an at-home exercise program started soon after hospitalization and continuing for 4 weeks following discharge can improve functional recovery in HFpEF patients. Volunteers will be randomly assigned to receive neuromuscular electrical stimulation (NMES) of their quadriceps muscles or not to receive NMES (control group). Volunteers will be evaluated during hospitalization and 4 weeks following discharge. Assessments will include measurements of physical function by 6 minute walk test and the Short Physical Performance Battery, as well as assessment of subjective physical functional capacity and quality of life using the Medical Outcomes Short form 36 and Kansas City Cardiomyopathy questionnaire.

6 Minute Walk Distance (6MW)
6 MW was developed to assess cardiopulmonary fitness in patients with lung and cardiac disease, and has been validated in heart failure patients. It assesses the distance that a patient can walk in 6 minutes time around a standard course.
Time frame: Change from Hospital Discharge (Within 1 day) to 4-weeks post-discharge
Short Physical Performance Battery
Short Physical Performance Battery is composed of three tasks assessing balance, gait speed, and ability to stand from a chair. Units on a scale for each domain range from of 0-4 for a total score of 0 to 12, with a higher score indicating better physical function.
Time frame: Change from Hospital Discharge (Within 1 day) to 4-weeks post-discharge
Katz Index of Independence in Activities of Daily Living
The Katz Index of Independence in Activities of Daily Living, commonly referred to as the Katz ADL, is the most appropriate instrument to assess functional status as a measurement of the client's ability to perform activities of daily living independently. Clinicians typically use the tool to detect problems in performing activities of daily living and to plan care accordingly. The Index ranks adequacy of performance in the six functions of bathing, dressing, toileting, transferring, continence, and feeding. Clients are scored yes/no for independence in each of the six functions. A score of 6 indicates full function, 4 indicates moderate impairment, and 2 or less indicates severe functional impairment.
Time frame: Hospital discharge (Within 1 day) and 4-weeks post-discharge
Lawton Instrumental Activities of Daily Living (IADL) Scale
The Lawton Instrumental Activities of Daily Living Scale (IADL) is an appropriate instrument to assess independent living skills. These skills are considered more complex than the basic activities of daily living as measured by the Katz Index of ADLs. The instrument is most useful for identifying how a person is functioning at the present time, and to identify improvement or deterioration over time. There are eight domains of function measured with the Lawton IADL scale. Women are scored on all 8 areas of function; historically, for men, the areas of food preparation, housekeeping, laundering have been excluded. Since men regularly complete food preparation, housekeeping, and laundering tasks, they were scored in all 8 domains as well. Clients are scored according to their highest level of functioning in that category. A summary score ranges from 0 (low function, dependent) to 8 (high function, independent) for women and men.

Medical Outcomes Short Form 36
The Medical Outcomes Short Form 36 is a questionnaire that assesses self-reported health and physical functional status. There are 36 questions that reflect eight sub-domains of health included in this questionnaire. Scores for each domain represent weighted sums of the questions in each sub-domain. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. This measure represents the total computed score across all sub-domains. Lower scores represent worse overall health, while higher scores represent better health.
