Role of Exercise in Diastolic Heart Failure

May 27, 2015 updated by: University of Michigan

Relationship of Cardiovascular and Muscular Capacity to Daily Functioning in Frail Older Adults

Diastolic heart failure is now being recognized as a key form of heart failure in older people. The focus of this research is to study ways to improve and maintain physical activity and functioning. This knowledge may improve the health and well-being in people with diastolic heart failure.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Functional circuit training and lifestyle counseling
Behavioral: Functional circuit training and lifestyle counseling

Tests are performed at the beginning, and repeated after 12 and 24 weeks:

  • Measure general fitness levels such as walking, strength and balance.
  • Walk on a treadmill to measure your maximum fitness while wearing a mask to analyze your oxygen use.
  • Blood and urine tests and a heart ultrasound.
  • Questionnaires & activity measures.

Group assignment for 12 weeks:

-Exercise classes & activity guidance: Twice-weekly class that focuses on exercises that are similar to daily activities, such as walking and carrying objects. Obtain customized information and education to help you exercise and follow a low salt diet.

Follow-up:

-Monthly phone calls during the 12 week follow up period.
Active Comparator: Health education and independent walking
Behavioral: Health education and independent walking

Tests are performed at the beginning, and repeated after 12 and 24 weeks.

  • Measure general fitness levels such as walking, strength and balance.
  • Walk on a treadmill to measure your maximum fitness while wearing a mask to analyze your oxygen use.
  • Blood and urine tests and a heart ultrasound.
  • Questionnaires & activity measures.

Group assignment for 12 weeks:

-Health education and walking: Weekly health education classes covering general topics related to heart failure, like medications, diet and exercise. Receive a pedometer for an at-home walking program.

Follow-up:

-No follow up support
