Why do panic attacks and heart attacks feel so similar?
Chest pain, a racing heart, shortness of breath, and sudden intense anxiety can occur during both a panic attack and a heart attack. It is precisely this overlap that makes the situation so frightening. However, it is not possible to reliably distinguish a heart attack from a panic attack at home based on individual symptoms alone.
1. When chest pain suddenly triggers a fear of dying
An uncomfortable sensation in the chest is sometimes enough to trigger intense fear within a matter of moments. The heart begins to beat faster, breathing changes, and the thought immediately arises: Am I having a heart attack right now?
During a panic attack, this fear can feel very real. The attack typically begins suddenly and is accompanied by an intense physical and psychological alarm response. In addition to heart palpitations or a racing heart, chest pain or a feeling of tightness, shortness of breath, trembling, sweating, dizziness, and nausea may occur. Some people also experience tingling, hot flashes, or the feeling that their surroundings are unreal. A particularly characteristic symptom is the intense fear of losing control or dying.
But this is precisely where the problem lies: a heart attack can also cause fear of death, chest pain, shortness of breath, dizziness, and sweating. Often, a pronounced feeling of pressure or tightness in the chest is also present. Therefore, especially in the case of first-time or severe chest symptoms, one should not assume that “it’s just psychological.” Even people who are already familiar with panic attacks can develop a physical illness independently of them.
2. Why a racing heart, shortness of breath, and dizziness can occur in both conditions
The fact that both conditions feel similar does not mean that the same thing is happening in the body. During a panic attack, the body’s alarm system becomes highly activated. Anxiety can become very intense within a short period of time and trigger numerous physical changes. Rapid breathing, in particular, can contribute to additional symptoms such as dizziness or tingling. These perceived symptoms, in turn, can reinforce the fear that something is wrong with the heart—which causes the panic to intensify further.
In contrast, a heart attack is an acute physical problem. A coronary artery is blocked, so that part of the heart muscle is no longer receiving enough oxygen. Without prompt treatment, heart muscle tissue can die. A heart attack is therefore life-threatening and requires immediate medical attention. Nevertheless, the similar symptoms can make both situations feel almost identical to those affected at first.
And that is precisely why the most important rule in this situation is very simple: If you suspect a heart attack—especially if you experience new or severe chest pain—you should immediately call 112. Do not wait to see if the symptoms go away on their own. The Federal Health Portal explicitly recommends calling 112 in the event of chest pain.
Panic Attack or Heart Attack?
Panic attack or heart attack—what are the differences?
Despite the similar symptoms, there are characteristics that occur more frequently in a panic attack or a heart attack. They can help with medical diagnosis—but cannot reliably rule out a heart attack. Medical tests such as an ECG and blood tests are necessary for that.
1. How the symptoms may differ
In the case of a heart attack, severe chest discomfort is often the primary symptom. Those affected may feel intense pressure, tightness, or a burning sensation behind the breastbone. The pain may radiate to other parts of the body, such as one or both arms, the shoulder, back, neck, jaw, or upper abdomen. Shortness of breath, nausea, paleness, and cold sweats may also occur.
Chest tightness or chest pain can also occur during a panic attack. These are often accompanied by a racing heart, rapid breathing, dizziness, trembling, sweating, or tingling. A particularly typical symptom is the sudden feeling of intense danger: At that moment, some people are convinced they are about to die, faint, or lose control.
Nevertheless, it would be dangerous to make a blanket comparison along the lines of “pressing pain means a heart attack; stabbing pain means a panic attack.” A heart attack can present in various ways. Not everyone experiences the classic severe chest pain, and the nature and radiation of the pain can also vary. In addition, heart attacks cause less typical symptoms in some people. This is more common, among others, in women, older adults, and people with diabetes. In some cases, shortness of breath, nausea, weakness, or severe exhaustion may be more noticeable than the classic chest pain. A single symptom is therefore not sufficient to distinguish between a panic attack and a heart attack.
2. What the Timeline Can Reveal
The course of the symptoms can also provide clues. A panic attack usually begins suddenly and reaches a high intensity within a short time. Gesundheitsinformation.de states that a panic attack generally lasts about 10 to 20 minutes. Afterward, the strong alarm reaction typically subsides. This explains why some people affected by panic attacks recognize a very clear pattern in retrospect: Within a few minutes, intense anxiety sets in, the physical symptoms reach their peak, and then the intensity gradually subsides again.
In contrast, symptoms of a heart attack may persist. But here, too, the same rule applies: Time alone is not a reliable self-test. A heart attack can unfold in different ways, and symptoms can vary. Conversely, individual symptoms of a panic attack may be felt longer than the actual phase of peak anxiety. That’s why no one experiencing new chest pain should wait 20 or 30 minutes to see if it’s “just a panic attack.” Especially in the case of a possible heart attack, waiting costs valuable time. If an acute heart attack is suspected, prompt medical care is crucial,
3. Why Accompanying Symptoms Are Important
It is not only the chest pain itself that is relevant for medical assessment. It is also important to note which other symptoms occur simultaneously and how they are related. Severe pressure or tightness in the chest, along with shortness of breath, nausea, paleness, or cold sweats, can be warning signs of a heart attack. Pain radiating to the arms, back, neck, jaw, or upper abdomen should also be taken seriously.
In contrast, a panic attack is often accompanied by additional sensations such as trembling, tingling, dizziness, or a feeling of unreality. Altered, rapid breathing can further intensify some of these symptoms.
However, even these accompanying symptoms do not provide a clear-cut distinction. For example, sweating, shortness of breath, dizziness, and intense anxiety can occur in both conditions. Therefore, the most important message of this comparison is not to memorize as many differences as possible. Rather, it is this: If the symptoms are new, severe, or unusual, and a heart attack cannot be definitively ruled out, the situation should be treated as a potential medical emergency.
What Happens in the Body During a Panic Attack?
A panic attack can feel as if the body has suddenly spiraled out of control. In fact, an intense fear response is taking place: heart rate, breathing, and alertness change within a short period of time. It becomes particularly distressing when these physical reactions themselves are perceived as signs of acute danger.
1. When the fear response becomes physically noticeable
Anxiety is not just a feeling. It triggers a series of reactions in the body that are originally intended to prepare us for potential danger. The heart beats faster, breathing may quicken, muscles tense up, and attention becomes more focused on potential threats. During a panic attack, this alarm response is particularly intense. This may explain why the symptoms feel so immediately physical. A racing heart, chest tightness, shortness of breath, dizziness, trembling, and sweating are not imagined sensations—those affected actually perceive distinct physical changes.
Rapid or shallow breathing can also contribute to additional symptoms. Some people may then experience, for example, dizziness or tingling in their hands and fingers. At the same time, they may feel as though they cannot get enough air, even though the altered breathing itself may be part of the anxiety response. The challenge is this: Anyone experiencing such symptoms for the first time does not know at that moment what is causing them. And even in cases of known panic attacks, one should not automatically assume that new or unusual chest discomfort has the same cause. Therefore, attributing the symptoms to a panic attack should never be used to rule out a possible heart attack on one’s own.
2. How a racing heart can lead to even more anxiety
In panic attacks, it’s often not just the physical reaction itself that plays a role, but also the meaning attributed to it. The heart begins to beat faster. The thought arises: Something is wrong with my heart. This increases the anxiety. The body reacts even more strongly. And the even more pronounced heart palpitations ultimately seem to confirm that something dangerous is indeed happening. Thus, within a short time, a cycle of physical sensations, threatening interpretations, and increasing anxiety can develop. The S3 guideline on anxiety disorders also describes this “vicious cycle model of anxiety” as a component of psychoeducation for panic disorders.
Especially after a very intense attack, awareness of one’s own body may also increase. A single strong heartbeat, a slight change in breathing, or a brief feeling of dizziness may be noticed immediately. The thought “Here we go again” can then trigger new anxiety. With recurring panic attacks, this can lead to a fear of anxiety itself. Those affected no longer fear only the attack itself, but also when and where the next one might occur. Some therefore begin to avoid certain places or situations. Recurring, unexpected panic attacks, combined with persistent worry about further attacks or corresponding avoidance behavior, may indicate a panic disorder. However, it’s important to distinguish between this explanation and an acute situation: Anyone currently experiencing new or severe chest discomfort should not try to conclude that it’s “just panic” based on a supposed anxiety cycle. In the case of a possible heart attack, the physical cause must first be medically evaluated.
When should you take immediate action if you have chest pain?
With possible heart attack symptoms, time is of the essence. Therefore, you should not first try to figure out the cause of the symptoms on your own based on the type of pain, its duration, or previous panic attacks. If you suspect a heart attack, you should call 112 immediately.
1. Warning Signs That Indicate You Should Call 112
Severe pain, pressure, or a pronounced feeling of tightness in the chest should be taken particularly seriously. The symptoms may occur behind the breastbone and radiate to other parts of the body—for example, to one or both arms, the back, neck, jaw, shoulder blades, or upper abdomen. Shortness of breath can also be an important warning sign. Other symptoms may include paleness, cold sweat, nausea, or a strong feeling of weakness. It’s important to note that a heart attack does not always present with the classic symptoms of severe chest pain.
For this very reason, the decision to call emergency services should not depend on whether all typical symptoms are present at the same time. Even a pre-existing panic disorder does not protect against a heart attack. People who are familiar with panic attacks may be inclined to quickly attribute familiar symptoms to anxiety. However, if chest pain is new, unusually severe, or feels different from previous attacks, it should not simply be dismissed as panic. If a heart attack is suspected, the German Heart Foundation strongly recommends not waiting to see if the symptoms go away, but rather calling emergency services at 112.
2. Why You Shouldn’t Wait It Out When in Doubt
Precisely because panic attacks often subside after a few minutes, you might think: I’ll just wait a moment and see if it gets better. With possible heart attack symptoms, that is exactly not a good strategy.
A heart attack occurs when the heart muscle tissue is no longer receiving an adequate supply of blood—and thus oxygen. The longer this condition persists, the greater the potential damage. Prompt medical care is therefore crucial. Nor is the duration of symptoms a reliable indicator. While panic attacks often last about 10 to 20 minutes, this does not mean that symptoms that improve after a short time are harmless—or that symptoms that last longer are automatically caused by a heart attack.
The distinction is made in a medical setting. There, symptoms and medical history can be assessed, and tests such as an ECG and blood tests can be performed. Therefore, a simple rule applies here: It’s better to call 112 once too soon than to wait and see if a possible heart attack is developing. This is especially true in cases of severe or new-onset chest pain, or a distinct feeling of pressure or tightness in the chest, shortness of breath, or other symptoms that could be consistent with a heart attack. The German Heart Foundation emphasizes that if a heart attack is suspected, call 112 immediately and do not wait.
