Depression, anxiety, stress can lead to poor heart health – India Today
Depression is often seen as a mental health issue—but growing evidence shows it can also take a serious toll on your heart. A large new study suggests that long-term emotional stress caused by depression and anxiety may quietly increase the risk of heart attack, stroke, and heart failure.
Researchers from Mass General Brigham analyzed health data from more than 85,000 adults and found a clear link between emotional distress and cardiovascular disease. The takeaway is simple but powerful: your emotional health and heart health are deeply connected.
How Depression and Anxiety Affect the Heart
The study found that people with depression or anxiety tend to have an overactive stress response system in the brain. This constant “fight or flight” mode puts extra strain on the body over time.
Here’s what the researchers observed:
- Overactive stress circuits in the brain, especially in the amygdala, which controls fear and stress
- Lower heart rate variability, a sign that the nervous system is under constant strain
- Higher inflammation levels, which can slowly damage blood vessels
Together, these changes create a chain reaction that raises the risk of heart disease—even if someone doesn’t smoke, has normal blood pressure, or eats reasonably well.
Why Having Both Depression and Anxiety Is Riskier
One of the most striking findings was how much risk increases when depression and anxiety occur together.
- People with either depression or anxiety had a higher risk of heart problems
- Those with both conditions faced about a 32% greater risk of major cardiovascular events compared to people with just one condition
This higher risk remained even after researchers accounted for lifestyle habits, income level, and traditional heart disease risk factors.
What the Study Followed
- 85,551 participants from the Mass General Brigham Biobank
- Followed for an average of 3.4 years
- 3,078 people experienced serious heart events like heart attacks, strokes, or heart failure
Advanced brain scans and blood tests in a subset of participants confirmed the biological stress pathway linking emotional distress to heart damage.
Why This Matters for Everyday Life
Doctors say these findings change how we should think about prevention.
Mental health isn’t just about mood—it’s about long-term physical survival. Managing chronic stress, anxiety, or depression may help protect the heart just as much as diet, exercise, or medication.
While this study doesn’t prove cause and effect, it strongly suggests that stress-reduction therapies, lifestyle changes, and inflammation control could play a role in lowering future heart disease risk.
The Bottom Line
Taking care of your emotional well-being isn’t optional—it’s essential for heart health. If you’re dealing with long-term stress, anxiety, or depression, addressing it may help protect both your mind and your heart in the years ahead.
