The Claim
In patients with heart failure with preserved ejection fraction, 12 months of combined endurance and resistance exercise training does not significantly change diastolic function as assessed by the E/e' ratio compared with usual care.
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, 12 months of combined aerobic and strength training does not significantly change how well the heart relaxes between beats, as measured by the E/e' ratio.
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 change diastolic function as assessed by the E/e' ratio compared with usual care.
Exercise strengthens the leg muscles and helps them use oxygen better, so people with heart failure feel more capable. But exercise does not change the stiffness of the heart muscle itself, so the heart's ability to fill with blood stays the same.
What the research says
1 studyThe study gave the exact same exercise program to the same type of heart failure patients and found that the ultrasound measure of heart stiffness (E/e') did not change significantly compared to patients who got usual care, so it supports the claim.
