Chest pain is the second most common reason for emergency room visits in the United States, driving roughly 8 million ER trips per year according to the CDC. While chest pain understandably triggers fear of a heart attack, the reality is that most ER visits for chest pain turn out to be non-cardiac in origin. Still, the stakes are too high to guess. Understanding when to go to the ER for chest pain is one of the most important health decisions you can make — because when a heart attack is happening, every minute of delay costs heart muscle.
When to seek emergency care: Call 911 immediately if you experience chest pain or pressure lasting more than a few minutes, chest pain with shortness of breath, sweating, nausea, or pain radiating to the arm, jaw, or back, or any chest pain with lightheadedness, fainting, or a rapid or irregular heartbeat. Do not drive yourself to the hospital — call 911 so treatment can begin in the ambulance.
Heart Attack Warning Signs
A heart attack (myocardial infarction) occurs when blood flow to a section of the heart muscle is blocked, usually by a blood clot in a coronary artery. Recognizing the warning signs is critical because clot-dissolving treatments and emergency procedures work best when administered within the first hour.
According to the American Heart Association, classic heart attack symptoms include:
- Chest pressure, squeezing, or fullness. Often described as an elephant sitting on the chest. The sensation typically lasts more than a few minutes or goes away and comes back.
- Pain radiating to the arm, jaw, neck, or back. Left arm pain is the most well-known, but pain can also travel to the right arm, both arms, the jaw, teeth, neck, or upper back.
- Shortness of breath. This may occur with or without chest discomfort and can be the only symptom in some patients.
- Cold sweats, nausea, or lightheadedness. Breaking out in a cold sweat without exertion, feeling nauseated, or becoming dizzy alongside chest symptoms is a red flag.
Women are more likely than men to experience “atypical” heart attack symptoms — shortness of breath, nausea, back or jaw pain, and extreme fatigue — without classic crushing chest pain. This contributes to delays in seeking care and worse outcomes. If you are a woman experiencing any combination of these symptoms, do not wait for textbook chest pain to appear.
Other Serious Causes of Chest Pain
Heart attacks are not the only life-threatening cause of chest pain. Several other emergencies present with chest symptoms and require immediate care.
Pulmonary embolism. A blood clot in the lungs causes sudden, sharp chest pain that worsens with breathing, along with shortness of breath, rapid heartbeat, and sometimes coughing up blood. Risk factors include recent surgery, prolonged immobilization, cancer, and a history of blood clots.
Aortic dissection. A tear in the wall of the aorta causes sudden, severe, tearing pain in the chest or upper back. This is a surgical emergency with a high mortality rate if not treated immediately.
Tension pneumothorax. A collapsed lung causes sudden, sharp chest pain on one side and severe shortness of breath. It can occur spontaneously (especially in tall, thin young men) or following chest trauma.
Pericarditis. Inflammation of the sac surrounding the heart causes sharp chest pain that worsens when lying down and improves when sitting up and leaning forward. While not always an emergency, severe cases require hospital evaluation to rule out complications.
When Chest Pain May Not Be an Emergency
Many causes of chest pain are uncomfortable but not immediately dangerous. Learning when to go to the ER for chest pain also means recognizing patterns that suggest non-cardiac causes.
Musculoskeletal chest pain. Pain that worsens when you press on the chest wall, changes with body position, or is reproducible with specific movements is likely related to the muscles, ribs, or cartilage — not the heart. Costochondritis (inflammation of the cartilage connecting ribs to the breastbone) is one of the most common causes of non-cardiac chest pain.
Acid reflux (GERD). A burning sensation behind the breastbone that worsens after eating, when lying down, or when bending over is often gastroesophageal reflux. It can closely mimic cardiac chest pain, which is why doctors sometimes run cardiac tests before diagnosing GERD. However, if the burning is a familiar pattern that responds to antacids, it is likely reflux.
Anxiety and panic attacks. Panic attacks can produce chest tightness, palpitations, shortness of breath, tingling, and a sense of impending doom — symptoms that convincingly mimic a heart attack. If you have a history of panic disorder and recognize the pattern, the situation may not require an ER visit. But if you are unsure, err on the side of caution — it is better to have a panic attack evaluated in the ER than to dismiss a heart attack as anxiety.
Respiratory infections. Pneumonia, bronchitis, and pleurisy can all cause chest pain, typically worsened by coughing or deep breathing. These usually require a doctor’s visit but not always an ER trip unless breathing is significantly compromised.
A Decision Framework: ER, Urgent Care, or Doctor’s Office?
Use this framework to guide your decision, but remember that when to go to the ER for chest pain always defaults to “when in doubt, go.”
Call 911 or go to the ER if:
- Chest pain is severe, sudden, or crushing
- Pain lasts more than a few minutes
- Pain radiates to the arm, jaw, neck, or back
- You have shortness of breath, sweating, nausea, or dizziness with the pain
- You have a history of heart disease or multiple cardiac risk factors
- You experience palpitations with the pain
- Symptoms came on during physical exertion
Urgent care or same-day doctor visit may be appropriate if:
- Pain is mild, has been present for days without worsening, and is reproducible with movement or pressing on the chest
- You have no shortness of breath, sweating, or radiation to the arm or jaw
- Symptoms consistently occur with eating and respond to antacids
- You have a known history of similar episodes diagnosed as non-cardiac
Schedule a routine appointment if:
- You experience occasional mild chest discomfort that resolves quickly and has no red-flag features
- You want cardiac risk assessment and screening
What Happens at the ER for Chest Pain
When you arrive at the ER with chest pain, you will be triaged rapidly. Chest pain is categorized as high priority, and you can expect:
ECG (electrocardiogram) — usually within 10 minutes of arrival. This test detects heart rhythm abnormalities and signs of an active heart attack.
Blood tests — including troponin, a protein released when heart muscle is damaged. Troponin levels may need to be checked twice, several hours apart, to confirm or rule out a heart attack.
Chest X-ray — to evaluate the lungs and heart size.
Additional testing — depending on initial results, you may undergo a CT scan (especially to rule out pulmonary embolism), echocardiogram, or stress test. The ER will provide pain management while the workup is underway.
An ER visit for chest pain typically costs $3,000 to $10,000 without insurance, depending on the testing required. For guidance on managing these expenses, see our healthcare costs guide.
Risk Factors for Heart-Related Chest Pain
Your personal risk factors should lower your threshold for seeking emergency care. According to the National Heart, Lung, and Blood Institute, major risk factors for heart attack include age (men over 45, women over 55), family history of early heart disease, smoking, high blood pressure, high cholesterol, diabetes, obesity, physical inactivity, and chronic stress. The more risk factors you have, the more seriously you should take any new chest pain.
Frequently Asked Questions
How do I know if chest pain is a heart attack or anxiety?
Heart attack pain typically builds gradually, feels like pressure or squeezing, radiates to the arm or jaw, and comes with sweating or shortness of breath. Anxiety-related chest pain often feels sharp or stabbing, is accompanied by tingling and a racing heart, and peaks within about 10 minutes. However, these patterns overlap significantly, and you cannot reliably distinguish between the two at home. If there is any doubt, call 911.
Can chest pain be a sign of something other than a heart problem?
Absolutely. Musculoskeletal pain, acid reflux, respiratory infections, gallbladder disease, and panic attacks all cause chest pain. In fact, most ER visits for chest pain are ultimately attributed to non-cardiac causes. However, ruling out cardiac causes is essential because the consequences of missing a heart attack are severe.
Should I drive myself to the ER for chest pain?
No. If you suspect a heart attack, call 911. Paramedics can begin life-saving treatment in the ambulance — including administering aspirin, nitroglycerin, and oxygen — and they can transmit your ECG to the hospital so the cardiac team is ready when you arrive. Driving yourself delays treatment and puts you at risk if you lose consciousness behind the wheel.
Is it normal to have chest pain that comes and goes?
Intermittent chest pain can be caused by many conditions, from musculoskeletal problems to angina (reduced blood flow to the heart that occurs with exertion and resolves with rest). Angina is not a heart attack, but it is a warning sign that your coronary arteries are narrowing. Any pattern of recurrent chest pain, especially with exertion, should be evaluated by a cardiologist.
At what age should I start worrying about chest pain?
Heart attacks can occur at any age, though risk increases significantly after 45 for men and 55 for women. Young adults with risk factors like smoking, diabetes, obesity, or a strong family history of early heart disease should take chest pain seriously regardless of age. The American Heart Association recommends cardiac risk assessment starting at age 20.
The Bottom Line
Knowing when to go to the ER for chest pain could save your life. The rule is simple: if chest pain is severe, lasts more than a few minutes, or is accompanied by shortness of breath, sweating, nausea, or pain radiating to the arm or jaw, call 911 immediately. Non-cardiac chest pain from musculoskeletal causes, reflux, or anxiety is far more common but cannot be reliably distinguished from a heart attack without medical testing. When in doubt, always choose the ER. The cost of an unnecessary visit is nothing compared to the cost of a missed heart attack.
