Exercise training meta-analysis of trials in patients with chronic heart failure (ExTraMATCH)
Open accessAbstract
OBJECTIVE: To determine the effect of exercise training on survival in patients with heart failure due to left ventricular systolic dysfunction. DESIGN: Collaborative meta-analysis. Inclusion criteria Randomised parallel group controlled trials of exercise training for at least eight weeks with individual patient data on survival for at least three months. Studies reviewed Nine datasets, totalling 801 patients: 395 received exercise training and 406 were controls. MAIN OUTCOME MEASURE: Death from all causes. RESULTS: During a mean (SD) follow up of 705 (729) days there were 88 (22%) deaths in the exercise arm and 105 (26%) in the control arm. Exercise training significantly reduced mortality (hazard ratio 0.65, 95% confidence interval, 0.46 to 0.92; log rank chi(2) = 5.9; P = 0.015). The secondary end point of death or admission to hospital was also reduced (0.72, 0.56 to 0.93; log rank chi(2) = 6.4; P = 0.011). No statistically significant subgroup specific treatment effect was observed. CONCLUSION: Meta-analysis of randomised trials to date gives no evidence that properly supervised medical training programmes for patients with heart failure might be dangerous, and indeed there is clear evidence of an overall reduction in mortality. Further research should focus on optimising exercise programmes and identifying appropriate patient groups to target.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
