What is the role of hair cortisol as a biomarker for chronic stress in cardiovascular disease (CVD)?

In one paragraph

Saliva Cortisol Stress Test, a review (Curr Cardiol Rep 2019, PMID 31471749) — elevated hair cortisol levels are associated with both the incidence of CVD and poorer recovery and treatment outcomes. No numeric effect size is reported for Saliva Cortisol Stress Test in the source abstract.

Plain-English summary written and published by Magellan Longevity · medical review by Gabriel Radu, DO (physiatrist, NPI 1376861765). We summarize what the paper reported — we did not run this study.

The takeaway

Hair cortisol is a promising biomarker for chronic stress linked to cardiovascular disease and its risk factors, but more robust research is needed.

The question

What is the role of hair cortisol as a biomarker for chronic stress in cardiovascular disease (CVD)?

What they tested

Hair cortisol may be a reliable biomarker of chronic stress, and elevated levels may be associated with the incidence, prognosis, and cardiometabolic risk factors of CVD.

How they did it

This is a review article that outlines the cardiovascular consequences of cortisol excess and provides an overview of recent studies investigating the relationship between hair cortisol and CVD. It also discusses clinical implications, limitations, and future research directions.

What they found

Hair cortisol provides quantification of total cortisol secreted into hair over several weeks, making it a potential biomarker for chronic stress. Elevated hair cortisol levels are associated with both the incidence of CVD and poorer recovery and treatment outcomes. Increased hair cortisol concentration has also been linked with cardiometabolic risk factors for CVD, including high blood pressure, diabetes, and adiposity.

What it means

Hair cortisol is a promising biomarker of chronic cortisol excess that may contribute to both the pathogenesis and prognosis of CVD.

Limitations

The current evidence relies on small-scale cross-sectional studies.
