Call 911 now if you have chest pain
Chest pain, pressure, tightness, or squeezing — especially with shortness of breath, sweating, nausea, lightheadedness, or pain spreading to the arm(s), jaw, neck, or back — can be a heart attack. Call 911 immediately.
Do not drive yourself to the hospital. Call 911 so paramedics can begin treatment on the way and alert the hospital’s cardiac team. Do not wait to “see if it passes” — with a heart attack, every minute of delay costs heart muscle, and treatment works best in the first hour.
Symptoms can be subtle. Women, people with diabetes, and older adults may have a heart attack without classic crushing chest pain — instead feeling shortness of breath, nausea, unusual fatigue, or discomfort in the jaw, neck, or back. When in doubt, call 911.
Take an aspirin only if 911 or a clinician tells you to and you are not allergic to it and have no reason to avoid it. Do not delay calling 911 to look for aspirin.
Chest pain is one of the most common reasons for emergency room visits in the United States, accounting for millions of ER trips every year. While chest pain understandably triggers fear of a heart attack, 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, and the safest rule when you are unsure is to call 911.
Heart Attack Warning Signs
A heart attack (myocardial infarction) occurs when blood flow to part of the heart muscle is blocked, usually by a clot in a coronary artery. Recognizing the warning signs is critical because emergency treatments to restore blood flow work best when they are started early.
According to the American Heart Association, common heart attack symptoms include:
- Chest pressure, squeezing, tightness, or fullness. Often described as an elephant sitting on the chest. It 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 discomfort 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 people.
- 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.
Atypical and subtle symptoms are common in some groups. Women are more likely than men to have “atypical” heart attack symptoms — shortness of breath, nausea, back or jaw pain, and extreme fatigue — without classic crushing chest pain. People with diabetes may feel little or no pain because of nerve damage, and older adults may simply feel weak, confused, or short of breath. In all of these groups, waiting for textbook chest pain to appear can be dangerous. If you are in one of these groups and something feels seriously wrong, call 911.
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 — which is another reason not to try to talk yourself out of calling for help.
Pulmonary embolism. A blood clot in the lungs causes sudden shortness of breath and sharp chest pain that is often worse when you breathe in, along with a rapid heartbeat and sometimes coughing up blood. Risk factors include recent surgery, a long period of immobilization (such as a long flight or bed rest), pregnancy, cancer, and a history of blood clots. This is an emergency — call 911.
Aortic dissection. A tear in the wall of the aorta causes sudden, severe, “tearing” or “ripping” pain in the chest or upper back. It is a surgical emergency with a high risk of death if it is not treated immediately. Call 911.
Tension pneumothorax (collapsed lung). A collapsed lung causes sudden, sharp chest pain on one side and severe shortness of breath. It can occur on its own (especially in tall, thin young people) or after chest trauma, and it needs emergency care.
Pericarditis. Inflammation of the sac around the heart causes sharp chest pain that often worsens when lying down and eases when sitting up and leaning forward. While not always an emergency, it can be serious and usually needs prompt 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 understanding the patterns that suggest a non-cardiac cause — while remembering that you should not try to self-diagnose serious chest pain. These patterns are context, not a green light to stay home when something feels wrong.
Musculoskeletal chest pain. Pain that worsens when you press on the chest wall, changes with body position, or is reproduced by specific movements is often related to the muscles, ribs, or cartilage rather than the heart. Costochondritis — inflammation of the cartilage connecting the ribs to the breastbone — is a common cause 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 pain, which is exactly why doctors often run heart tests before settling on a reflux diagnosis. A familiar pattern that reliably responds to antacids is more likely reflux — but a new or different episode deserves caution.
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 an established history of panic disorder and clearly recognize the pattern, the episode may not require an ER visit. But if there is any doubt, err on the side of caution: it is far better to have a panic attack checked in the ER than to dismiss a heart attack as anxiety.
Respiratory infections. Pneumonia, bronchitis, and pleurisy can all cause chest pain, usually worse with coughing or deep breaths. These often need a doctor’s visit but not always an ER trip — unless breathing is significantly compromised, in which case seek emergency care.
A Decision Framework: ER, Urgent Care, or Doctor’s Office?
Use this framework to guide your thinking, but remember that when to go to the ER for chest pain always defaults to “when in doubt, go” — and to calling 911 rather than driving if a heart attack is possible.
Call 911 (do not drive yourself) if:
- Chest pain or pressure is severe, sudden, or crushing
- Pain lasts more than a few minutes, or comes and goes
- Pain radiates to the arm(s), 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 feel palpitations, faintness, or an irregular heartbeat with the pain
- Symptoms began during physical exertion
- You have sudden “tearing” chest or back pain, or sudden shortness of breath with sharp pain worse on breathing
Urgent care or a same-day doctor visit may be appropriate if:
- Pain is mild, has been present for days without worsening, and is reproducible by movement or by 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 already diagnosed as non-cardiac
Schedule a routine appointment if:
- You have occasional mild chest discomfort that resolves quickly and has no red-flag features
- You want a cardiac risk assessment and screening
When you are genuinely unsure which category you are in, treat it as the emergency category. The whole point of the ER is to safely rule out the dangerous causes.
What Happens at the ER for Chest Pain
When you arrive at the ER with chest pain, you will be triaged quickly, because chest pain is treated as high priority. You can generally expect:
ECG (electrocardiogram) — usually within about 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 injured. Troponin is often checked more than once, several hours apart, to confirm or rule out a heart attack.
Chest X-ray — to evaluate the lungs and the size of the heart.
Additional testing — depending on the initial results, you may have a CT scan (especially to look for a pulmonary embolism or aortic dissection), an echocardiogram, or a stress test. The ER will manage your pain while the workup is underway.
Costs for an ER chest-pain evaluation vary widely and depend heavily on the testing required, your location, and your insurance; estimates commonly run into the thousands of dollars. Do not let cost stop you from calling 911 for possible heart-attack symptoms — the financial cost of an unnecessary visit is minor compared with the cost of a missed heart attack. 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 older age (risk rises after about 45 in men and 55 in women), a 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 — and the more readily you should call 911.
Frequently Asked Questions
How do I know if chest pain is a heart attack or anxiety?
Heart attack pain often builds gradually, feels like pressure or squeezing, may radiate 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 tends to peak within about 10 minutes. But these patterns overlap heavily, and you cannot reliably tell them apart at home. If there is any doubt, call 911.
Can chest pain be a sign of something other than a heart problem?
Yes. Musculoskeletal pain, acid reflux, respiratory infections, gallbladder disease, and panic attacks all cause chest pain, and most ER visits for chest pain are ultimately attributed to non-cardiac causes. Even so, ruling out cardiac and other dangerous causes is essential, because the consequences of missing a heart attack, pulmonary embolism, or aortic dissection 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 on the way and transmit your ECG so the cardiac team is ready when you arrive. Driving yourself delays treatment and puts you and others at risk if you lose consciousness at the wheel.
Should I take aspirin during a suspected heart attack?
Only if 911 dispatch or a clinician advises it and you have no allergy or other reason to avoid aspirin. Aspirin can help during some heart attacks, but it is not right for everyone, and you should never delay calling 911 to search for it. Let the 911 operator guide you.
Is it normal to have chest pain that comes and goes?
Intermittent chest pain can come from many conditions, from musculoskeletal problems to angina — reduced blood flow to the heart that occurs with exertion and eases with rest. Angina is not a heart attack, but it is a warning that the coronary arteries may be narrowing. Any pattern of recurrent chest pain, especially with exertion, should be evaluated by a clinician promptly, and sudden or severe episodes warrant 911.
At what age should I start worrying about chest pain?
Heart attacks can occur at any age, though risk increases significantly after about 45 in men and 55 in women. Younger adults with risk factors such as smoking, diabetes, obesity, or a strong family history of early heart disease should take chest pain seriously regardless of age. Ask your clinician when to begin cardiac risk assessment for you.
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 comes with shortness of breath, sweating, nausea, lightheadedness, or pain radiating to the arm, jaw, neck, or back, call 911 immediately — and do not drive yourself. Non-cardiac chest pain from muscles, reflux, or anxiety is more common, but it cannot be reliably distinguished from a heart attack without medical testing, and some non-cardiac causes are emergencies in their own right. When in doubt, always choose 911 and the ER. The cost of an unnecessary visit is nothing compared with the cost of a missed heart attack.
