Formatted Abstract/Summary Background:
Exercise training (ExT) improves functional capacity in systolic heart
failure, but the role of ExT in diastolic dysfunction patients (DD) is unclear.


Methods:Twenty four DD patients were randomized to ExT or normal treatment. ExT was
completed in 15 patients (8 men, 63±4 years, LVEF 55±9%) 9 DD patients undertook
usual treatment (7 men, 58±8 years, LVEF 57±7%). Peak VO2, quality of life QOL;
Minnesota Living with Heart Failure [MLWHF] and Hare-Davis [HD] questionnaires) and
echo measures (EF, systolic [Sm] and diastolic tissue velocity [Em] and filling pressure
[E/E’]) were performed at baseline and 16 weeks ExT.

Results:
Both groups showed similar baseline VO2 (13.2±5.8 vs 16.4±4.2 mls/kg/min,
p=0.16), Sm (5.2±1.2 vs 6.0±0.9 cm/s, p=0.10) and E/E’ (21.6±12 vs 11.2±10, p=0.12)
but different Em (3.7±3.8 cm/s vs 6.6±1.6, p=0.04). Baseline MLWHF and HD scores
were similar in both groups. After ExT, the increment in peak VO2 was significantly greater
in ExT (27%) versus control group (3%, p=0.02). Increment in peak VO2 was predicted by
baseline E and A wave velocity (r =0.87, p<0.001), but not by changes in echo parameters.
The only echo parameter which responded to training was contractile reserve (p=0.02)
versus usual treatment group. At 12 weeks, there was a significant improvement in the
total (p=0.01) and emotional (p=0.006) dimensions of MLWHF and HD (p=0.05) scores .

Conclusions:
In patients with exercise limitation attributed to DD, there is a significant
improvement in peak VO2 and QOL with ExT, in addition to usual medical therapy. This
improvement appears unrelated to changes in diastolic function.
