The Claim
Among patients with heart failure with preserved ejection fraction (HFpEF), 12 months of combined endurance and resistance exercise training is associated with a significantly better NYHA functional class compared to usual care, with an odds ratio of 7.77 (95% CI: 3.73-16.21) for improvement.
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.
For people with heart failure with preserved ejection fraction (HFpEF), a 12-month program of both endurance and resistance exercise improves heart failure symptoms more than usual care, with 7.77 times higher odds of improvement.

Exercise makes the leg muscles stronger and better at using oxygen. This improved muscle function lets the body do more work before getting tired, so daily activities become easier and heart failure symptoms improve.
What the research says
1 studyIn a big study, people with heart failure who did a year of combined exercise were about 7.7 times more likely to have their symptoms improve than those who got usual care.
