NCT00959660

Brief Summary

The purpose of this study is to examine the effects of weight loss via hypocaloric diet, aerobic exercise training, combined hypocaloric diet and exercise training, and attention control in patients with heart failure and a normal ejection fraction (HFNEF) and body mass index greater than or equal to 30.

    20 weeks

Secondary Outcomes (3)

  • Quality of Life

    20 weeks

  • Body Composition

    20 weeks

Study Arms (4)

Exercise Training

ACTIVE COMPARATOR

Exercise participants will undergo a 1-hour supervised exercise program 3 times per week for 20 weeks consisting primarily of walking exercise using an individualized exercise prescription based on the initial exercise stress testing results.

Behavioral: Exercise

Dietary Intervention

ACTIVE COMPARATOR

A hypocaloric diet will be developed to achieve a 2800 kcal/week deficit, which should produce about 0.4 kg (1 lb) weight loss per week.

Dietary Supplement: Dietary Intervention

Attention control

ACTIVE COMPARATOR

Attention control participants will be provided a counseling session regarding general health education at baseline and will be contacted by staff via telephone every 2 weeks to discuss general health status.

Other: Attention Control

Diet and Exercise

ACTIVE COMPARATOR

A hypocaloric diet will be developed to achieve a 2450 kcal/week deficit in addition to undergoing a 1-hour supervised exercise program 3 times per week for 20 weeks consisting primarily of walking exercise using an individualized exercise prescription based on the initial exercise stress testing results.
