Chest Pain From Anxiety: Why It Feels Like a Heart Attack

Why Your Brain Looks Inward

Naturally, your brain does the most logical thing it can do. It starts looking for potential threats so it can warn you about them, because the primitive brain isn’t designed to make you feel happy. It’s designed to keep you safe. It would always rather be safe than sorry.

So it uses past experiences and references to try and predict the future. And when it can’t find any danger outside of you, it looks inward, because the brain is aware that danger can come from within too.

Your brain has learned that heart attacks happen to people. Maybe you’ve even heard of people your own age getting one…

Now the brain decides this is a serious threat. There’s a possibility, even if the probability is actually really low.

This is also why small children don’t worry about heart attacks, their brain doesn’t even know such a thing exists yet. But for us adults, the brain looks inward using past experiences and references to predict a future, and the thought arrives: “what if something is wrong with my heart?”

This is what most doctors don’t explain, and honestly, it’s not really their fault. They check your heart, it’s fine, they send you home. Job done, from a medical standpoint.

Your heart’s fine, no need to worry, right?

Except it keeps racing like crazy for no apparent reason, so surely something must be wrong. Surely they missed something. And nobody explains why it keeps happening.

Why Chest Pain Specifically

Let’s talk about the chest pain part for a second, because I know that’s often the scariest piece of all this.

It’s not just your heart racing. It’s that tightness, that pressure, sometimes a sharp pain, sometimes more like someone’s sitting on your chest. And because it’s literally located right where your heart is, your brain jumps straight to the worst conclusion.

Here’s what’s actually causing it though.

Remember those chest and rib muscles I mentioned, the ones that tense up to prepare for fight or flight? That tension doesn’t just sit there quietly.

It pulls and tightens around your whole ribcage, and that alone can create a pressure or ache that feels nothing like a normal muscle tightening anywhere else in your body. It’s right there, right over your heart, so of course it feels alarming.

On top of that, when you’re anxious your breathing changes. It gets faster and shallower, which means you’re taking in more air than your body actually needs in that moment.

That can cause a buildup of tension in the chest wall too, sometimes even a sharp, stabbing kind of pain that comes and goes. This is what I used to experience a lot.

People often describe it as “catching” when they breathe in. That’s muscular, that’s from the breathing pattern, that’s not your heart. I remember feeling relieved (for a second) when my doctor did explain this part to me.

And then there’s the simple fact that once you’re scared of chest pain, you start paying very close attention to your chest. Which means you notice every twinge, every flutter, every bit of tightness that a non-anxious person would never even register.

Your attention basically turns into a spotlight, and whatever it lands on gets amplified.

So you’ve got muscle tension, altered breathing, and hyper-focused attention all stacking on top of each other. None of that is your heart struggling. All of it is uncomfortable, sure. But none of it is dangerous.

One thing that can help you tell the difference, just so you have a general sense, anxiety-related chest pain tends to shift around, come in waves, and ease up when you change position or focus on something else.

A cardiac event behaves very differently and usually comes with other very specific signs. I’m not saying this to replace a doctor, always get checked if you’re unsure, but once you’ve been cleared, this pattern is worth knowing so you’re not starting from zero every single time it shows up.

What many participants in the program have in common is that eventually, after worrying and catastrophizing so much for a long time, plus being checked out by doctors multiple times, they get fed up with it and just take “the risk” of assuming it’s anxiety.

Like Kyle who said “If it was a deadly disease that was unnoticed I would already have been dead in the past couple of years. It’s just BS – and I’m not going to engage in the minuscule chance it is something else than anxiety”.

The Mistake (And I Made It Hundreds of Times)

So here it is. The moment you think “what if this is a heart attack?” and start acting on that, you’ve made what I call the mistake.

I don’t mean that harshly. I mean it’s the most logical mistake in the world. I made it hundreds, maybe thousands of times.

The mistake is this. You’ve taken a perfectly normal physical response, your fight or flight system going off, and misinterpreted it as a sign of danger and acted on it.

And the second you do that, your brain believes you. It treats the danger as real and releases more adrenaline, which makes the sensations even stronger, which makes you more scared, which makes the brain release even more adrenaline.

Do you see the loop? Sensations -> misinterpretation -> fear response kicking in -> more sensations -> more fear.

That’s a panic or anxiety attack, not a heart attack. It’s a false alarm that feeds itself.

And here’s the thing that matters most: you cannot die from a panic attack. Your heart is not in danger. You’re not going to faint. You’re not going to lose it.

I know that sounds like one of those things people just say to make you feel better. But think about it from an evolutionary standpoint.

Fight or flight is a survival mechanism. Evolution would not have designed a system that kills you when it activates. That would be spectacularly bad engineering.

Lazy sabertooth tigers would be running the world if that were the case.

So yes, it feels dangerous. It feels completely, convincingly, terrifyingly real. I know, because I’ve been there.

I went to the doctor three times in one month convinced something was wrong with my heart. It wasn’t.

The body can only sustain a high amount of adrenaline for a limited time, so even at the absolute worst point, the peak sensations always passes.

In the case of constant sensations, often the result of cortisol that burns slower, you’ll also see that the more you respond, the less you notice it and the more the sensation dies down.

“I Know It’s Anxiety. It Still Happens Anyway.”

I can already hear some of you thinking, “I know this. I’ve been told it’s anxiety. I’ve read about it. But it still happens.”

And I know why.

The difference isn’t between knowing it intellectually and not knowing it.

The difference is between knowing it and actually behaving in a way that matches it. Even if you don’t fully believe it in the moment, you can still act as if it’s a false alarm. Just knowing it without acting in accordance with it doesn’t do anything on its own.

Here’s what’s actually happening. Your survival brain will always kick in first. Every single time. The rational brain genuinely goes offline for a moment, and then it comes back online.

That moment it comes back is your cue. That’s when you respond.

You don’t need to outrun the survival brain, because you won’t. Nobody does. You just need to correct your response each time you realize what’s happening. That’s the whole skill.

Instead of preventing the alarm, focus on catching it and choosing differently once you’re aware of it.

So the solution isn’t more information. You don’t need more convincing that you’re physically healthy, you’ve already had that. And if you haven’t seen a doctor yet, that should always be step one, just to rule out anything real.

But once you’ve been checked and cleared, what actually needs to change is your relationship with the sensations themselves, and that only happens through behavior, not through understanding alone.

What’s Making It Worse

Right now, the second those sensations show up, the racing heart, the chest tightness, whatever it is for you, your automatic response is resistance. And that resistance is what keeps the cycle alive.

That response is behavior. You either engage with the thought of having a heart attack, try to push it away, argue with it, use a smartwatch to track your heart rate constantly, take a trip to the ER, or do a breathing exercise just to calm down.

All of those things communicate to your nervous system that you’re in danger. They confirm the threat. They increase the adrenaline in your system, making your heart beat even faster – sensitizing yourself even more into survival mode.

It’s like now you’re not fighting one tiger, you’re fighting two.

And when you keep focusing on your heart specifically, you activate the sensors around your heart even more, so you actually feel and hear it beating more intensely.

That awareness triggers the fear response again, making your heart beat faster still. Checking in is also part of the problem.

What Actually Changes Things

What changes things is learning to meet those sensations differently. Not fighting them, not running from them, not trying to breathe them away, but allowing them to be there.

Acting as if you’re completely safe (because you are). Behaving as if you don’t really care about the discomfort (and you will stop caring eventually).

I know that sounds completely backwards. Why would you allow something that feels so terrible to just be there?

Because the moment you stop resisting, the moment you stop fighting the sensation, you remove the fuel from the fire.

When you don’t engage with this potential threat, your nervous system learns it doesn’t need to keep sending you all this nervous energy. Because clearly you’re not in danger. Because you’re not behaving as if you are.

Over time, it learns that in general, you’re not in so much danger that you need to be in survival mode from the moment you wake up to the moment you go to bed. It desensitizes.

It’s like a wave coming over you that you don’t have much control over in the moment. The only thing you can control is whether you fight it and make it worse, or allow it to crash over you and dissipate naturally, until it stops showing up altogether.

So if you’ve been to doctors, had your heart checked, and been told you’re fine, you probably are fine.

I’m not your doctor, and if you have a genuine medical concern, go get it checked. But if you’ve already been checked and cleared, what you’re experiencing is very likely the exact cycle I just described.

And the good news is, it’s not permanent. It’s not who you are. It’s a pattern your nervous system has learned, and patterns can be unlearned.

Even Far Into Recovery, This Fear Can Pull You Back

I want to share something else, because I think it matters.

I’ve spoken to people on calls who were nearly five years into dealing with anxiety and had gotten almost fully recovered. Genuinely close. And then one single intense episode hit, and the brain immediately decided it was a heart attack.

One of them put it simply: “I thought it’s heart attack. After that I start experiencing the fear and symptoms.”

One misinterpretation, and months of progress reset almost overnight. Not because they were further from recovery than they thought, but because that one moment of believing the catastrophe was real was enough to put the whole loop back into motion.

They started going back to the old pattern of behavior again: resistance.

I tell you this not to scare you, but because I want you to understand something important. This fear doesn’t just affect people early in their journey. It can find anyone, even people who are almost there, the moment they misinterpret a sensation as confirmation that something is seriously wrong.

This response that you’re learning is a muscle you’ll keep using, though the sensations will fade away. Like how I never feel that sting in my heart anymore. But I do overthink sometimes – and that’s my cue to respond.

And for some people, it’s not really about the symptom at all. Someone else described it to me this way: “My hesitation mostly is fear of death that what hold me back… the symptom is nothing.”

The chest pain, the racing heart, none of that was actually the core issue for him. Underneath it was the fear of dying itself, and the symptoms were just the trigger that brought that fear to the surface.

If that’s you too, you’re not alone in that, and it doesn’t mean this works any differently for you. It just means there’s an extra layer underneath the physical sensation that’s worth understanding as well.

It’s forcing us to look into our pattern and ask ourselves “Is this productive?”.

If worrying about dying makes you immortal, then yes. Otherwise… not so much.

This Took Me Six Years to Figure Out

Tens of thousands of dollars in therapy, courses, books, supplements, you name it. And it always came down to understanding this cycle and learning a new response to it.

We’ve had so many people in the program with heart anxiety specifically. A guy from the UK who finished the program a couple weeks ago used to get panic attacks in the shower because his heart rate would increase.

Johnny – who is someone you can now speak to if interested in the program – wouldn’t let his heart rate go over a certain threshold, afraid it would trigger a panic attack, or worse, an actual heart attack.

They learned what was truly happening and how to respond to it in a way that doesn’t make it worse. They got the proof, over and over, that it really was just anxiety, and that their heart could handle far more than they ever gave it credit for.

That’s the skill. It takes time to practice and master, but like any other skill, anyone can learn it.

Watch Johnny’s full story below, how it started, what he tried, and how he finally got out of it.

And if you want to understand why the things you’re doing to feel better, breathing exercises, grounding, reassurance seeking, are probably making it worse, I made a video on exactly that too. Probably one of the most important ones on the channel.

And if you’re at the point where you feel like you’ve tried everything and nothing’s working, I get it. I really do. Feel free to reach out to us. We work with people every day who were exactly where you are right now.

You’re going to be okay. And you’re not alone in this.
