The Claim
In patients with heart failure, perceived stress as measured by the PSS-10 questionnaire is not significantly associated with hair cortisol concentration across heart failure subtypes.
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.
In people with heart failure, self-reported stress levels do not correlate with the amount of cortisol measured in hair, indicating that subjective stress reports do not align with this objective biological marker of stress.
See the scientific wording
In patients with heart failure, perceived stress measured by the PSS-10 questionnaire is not significantly associated with hair cortisol concentration across subtypes, suggesting a dissociation between subjective stress reports and objective physiological stress biomarkers in this population.
In people with heart failure, the body's stress hormone system does not respond to feelings of mental stress, but it still reacts to physical activity by releasing cortisol into the hair. This means how stressed someone feels does not match the level of stress hormones in their body, because the system only turns on for physical exertion, not emotional strain.
What the research says
1 studyPeople with heart failure who say they feel stressed don’t necessarily have higher levels of cortisol in their hair, meaning how stressed they feel doesn’t always match what’s happening in their body.
