Stress and anxiety are often blamed for heart trouble, and sometimes rightly so. A psychiatrist separates the real risk from the overstated fear.
Column by Dr. Jaspreet Kaur
One of the most frequent questions put to psychiatric clinics during today’s visits, in one form or another, is this: “Can anxiety directly lead to a heart attack?”
It’s a relevant—and increasingly common—question. Between wellness websites and a growing commitment to taking mental health seriously, we are far more aware today of the link between the mind and the body than we were 25 years ago.
That increasing awareness is a good thing. But, like all good trends taken slightly too far, it has also given rise to confusion about where this link is real and where it has been overstated by the available scientific evidence.
A good deal of the concern is, in fact, justified. Over the long term, the consequences of chronic stress and anxiety on the cardiovascular system can be seen through objective, well-documented biological changes. People who experience significant, chronic life stress—from work, caregiving, financial pressures or grief—can have a higher long-term cardiovascular risk than those who don’t. The relationship can also work in the other direction: a cardiac event can lead to depression and anxiety, and the two can frequently occur together.
There are many other factors that can contribute, directly or indirectly, to both anxiety, stress and cardiac problems. An unhealthy lifestyle—including being overweight, unhealthy eating habits, lack of exercise, smoking, other addictions, poorly controlled blood pressure or blood sugar, disturbed sleep and excessive caffeine or energy-drink consumption—can add to the risk of both.
So, how does ongoing psychological stress affect the body?
Persistent or repetitive stress and anxiety, especially when left untreated, can lead to hormonal, biochemical and physical changes. When the body remains in a prolonged “fight or flight” state, it can trigger inflammatory responses and contribute to higher levels of stress hormones, raised cholesterol, hypertension and diabetes.
Over time, these factors can increase the chances of plaque formation in the arteries, potentially leading to narrowing or complete blockage and, ultimately, cardiovascular events such as heart attacks and strokes.
But anxiety disorders can also have a more immediate, physical relationship with the heart—though perhaps not quite as straightforward as many people imagine.
Panic attacks often bring on a pounding heart, a feeling of tightness in the chest or difficulty breathing. While an attack is happening, it can feel every bit like the beginning of a cardiac event, or even a near-death experience.
And this is hardly imaginary. The body is being flooded with adrenaline, and the physical sensations are very real, whether the trigger is cardiac or psychological.
It can be difficult to distinguish a panic attack from a heart attack. It is therefore no surprise that emergency departments frequently see people with acute panic episodes that convincingly mimic symptoms associated with cardiac problems. A skilled psychiatrist or cardiologist can make the diagnosis clinically, while tests such as an ECG and cardiac blood tests can help distinguish between the two.
Ultimately, what matters when communicating reliable health information is staying somewhere between the two extremes.
A person’s emotional life and the state of their heart are undoubtedly intertwined—through cumulative effects such as chronic inflammation, poor sleep and unhealthy coping mechanisms. But this does not typically happen through a single panicked outburst that causes immediate cardiac trauma.
That distinction is important clinically. It is also why long-term strategies to manage ongoing, poorly controlled stress—such as therapy, exercise, adequate sleep and social support—can be genuinely beneficial for cardiovascular health.
It isn’t helpful, when treating anxiety, to convince people that every moment of worry could trigger an acute myocardial event. That fear, by itself, can simply increase anxiety.
What matters most is holding both truths at once.
Every episode of chest pain must be taken seriously and investigated rather than dismissed as “just anxiety”. At the same time, every upsetting or difficult emotion does not necessarily warrant the additional trauma of assuming there is a cardiac problem.
Our brains and hearts, our thoughts and feelings, and their effects on physical processes are deeply interconnected. The important point is that these effects generally unfold over longer timelines, rather than within minutes.
And understanding that distinction can, ultimately, be a source of reassurance. n
