Association Between 6-Minute Walk Test Distance and Objective Variables of Functional Capacity After Exercise Training in Elderly Heart Failure Patients With Preserved Ejection Fraction: A Randomized Exercise Trial.

ABSTRACT:

Objective

To evaluate the change in the 6-minute walk test (6-MWT) distance relative to changes in key functional capacity measures after 16 weeks of exercise training in older patients (≥65y) who have heart failure with preserved ejection fraction (HFpEF).

Design

Prospective, randomized, single-blinded (by researchers to patient group) comparison of 2 groups of HFpEF patients.

Setting

Hospital and clinic records; ambulatory outpatients.

Participants

Participants (N=47) randomly assigned to an attention control (AC) (n=24) or exercise training (ET) (n=23) group.

Intervention

The ET group performed cycling and walking at 50% to 70% of peak oxygen uptake (V˙o₂peak) intensity (3d/wk, 60min each session).

Main outcome measures

V˙o₂
