JAMA Medical News How Stress May Connect Mental Health and Cardiovascular Disease
7 snips
Jan 23, 2026 Rita Rubin, lead senior staff writer who reports on biomedical research, explores a study tying stress to links between depression, anxiety, and heart disease. She breaks down biobank data and how stress markers may connect brain, immune, and autonomic systems. Practical stress-reduction tips like sleep, meditation, and yoga are discussed for protecting heart health.

Stress Biology Connects Mood And Heart Risk
- Researchers found stress-related biology may explain why depression and anxiety raise cardiovascular risk.
- Neural stress activity, reduced heart rate variability, and higher CRP partially mediated the link.
Large Biobank Shows Elevated Event Rates
- In ~86,000 participants, those with depression and anxiety had higher rates of major cardiovascular events over three years.
- Associations persisted after adjusting for traditional risk and lifestyle factors.
Mechanisms Partially Explain The Link
- Stress-related neural, autonomic, and immune changes indirectly affected the depression/anxiety–cardiovascular link.
- The study was observational, so causality isn’t proven but the relationship is plausible.
