The Claim
A 12-month program combining endurance and resistance exercise training does not significantly improve the modified Packer score, a hierarchical composite clinical endpoint (all-cause mortality, heart failure-related hospitalizations, changes in peak oxygen consumption, diastolic function (E/e′), NYHA class, and global self-assessment), in patients with heart failure with preserved ejection fraction (HFpEF) compared to usual care, showing a non-significant difference (Kendall's tau-b = -0.073, P = 0.17).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
A year-long program of endurance and resistance exercise does not significantly improve a combined heart failure outcome score in patients with heart failure with preserved ejection fraction compared to standard care. The score tracks death, hospitalizations, and changes in exercise capacity and heart function.
See the scientific wording
A 12-month program combining endurance and resistance exercise training does not significantly improve a hierarchical composite clinical endpoint, the modified Packer score, in patients with heart failure with preserved ejection fraction (HFpEF) compared to usual care. The composite comprised all-cause mortality, hospitalizations related to heart failure or exercise, and changes in peak oxygen consumption, diastolic function (E/e′), NYHA class, and global self-assessment. At 12 months, 20.5% of exercise patients improved versus 8.1% of usual care, but 42.9% versus 44.1% worsened, yielding a non-significant difference (Kendall’s tau-b = −0.073, P = 0.17).
Exercise makes the leg muscles better at using oxygen and stops them from shrinking, so patients feel less winded and can do more. But the heart’s stiffness and the risk of death or hospital stays do not change. Because the combined score counts death, hospital stays, and heart stiffness as the most important things, the overall score does not get better.
What the research says
1 studyThe study tested the exact same exercise program and measure as the claim, and found no significant difference in the overall score, so the claim is correct.
