The Claim

In patients with heart failure with preserved ejection fraction, 12 months of combined endurance and resistance exercise training does not significantly reduce the time to all-cause death or cardiovascular hospitalization compared with usual care.

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.

Cause and effect
1 study reviewed
In plain English

A 12-month program of combined endurance and resistance exercise does not significantly delay death from any cause or reduce heart-related hospitalizations in patients with heart failure with preserved ejection fraction, compared with standard care.

See the scientific wording

In patients with heart failure with preserved ejection fraction, 12 months of combined endurance and resistance exercise training does not significantly reduce the time to all-cause death or cardiovascular hospitalization compared with usual care.

Why this might work

Exercise makes the leg muscles stronger and better at using oxygen, so patients feel fitter and can do more. But the heart itself stays stiff and doesn't pump blood better, and that stiffness is what leads to fluid buildup and hospital stays. Since exercise doesn't fix the heart's stiffness, it doesn't change how long patients live or how often they go to the hospital.

1 study
  1. Study: Combined endurance and resistance exercise training in heart failure with preserved ejection fraction: a randomized controlled trial

    The study found that exercise training didn't significantly lower the chance of dying or being hospitalized for heart problems compared to usual care, which matches the claim.
