Reading time: About 20 minutes
Heart-attack discomfort may feel like pressure, squeezing, fullness, heaviness, burning, tightness, or indigestion.
It may be severe or mild.
It may last, improve, and return.
It may occur in the center, left, or right side of the chest and spread to one or both arms, the shoulders, back, neck, jaw, or upper stomach.
Some people mainly experience shortness of breath, nausea, sweating, faintness, unusual fatigue, weakness, or back or jaw discomfort.
Call emergency services for new, sudden, severe, persistent, spreading, exertional, or unexplained chest discomfort, especially when it occurs with shortness of breath, sweating, nausea, vomiting, dizziness, fainting, severe weakness, or a rapid or irregular heartbeat.
Do not drive yourself.
Call before taking aspirin.
Use nitroglycerin only when it was prescribed for you and follow your personal instructions.
If the person becomes unresponsive and is not breathing normally, begin CPR and use an AED.
Chest Pain vs Heart Attack: Quick Answer
Chest pain can come from many body systems.
A heart attack happens when blood flow to part of the heart becomes severely reduced or blocked.
You cannot safely rule out a heart attack from the feeling, location, duration, tenderness, trigger, age, or response to an antacid.
Call emergency services when chest discomfort:
- Feels like pressure, squeezing, tightness, heaviness, fullness, burning, or crushing
- Lasts more than a few minutes or goes away and returns
- Spreads to an arm, shoulder, back, neck, jaw, or upper stomach
- Occurs with shortness of breath
- Occurs with cold sweat, nausea, vomiting, dizziness, weakness, or fainting
- Is new, severe, worsening, or different from your usual angina
- Begins during exertion or occurs at rest
While waiting:
- Stop activity and sit in a safe position.
- Do not drive yourself.
- Follow the emergency dispatcher’s instructions.
- Use prescribed nitroglycerin only as directed for you.
- Take aspirin only if the dispatcher or a qualified professional says it is appropriate.
- Begin CPR and use an AED if the person is unresponsive and not breathing normally.

Critical Chest-Pain Warning
Call your local emergency number when a heart attack or another life-threatening cause is possible.
In the United States, call 911.
In the United Kingdom, call 999.
In many European countries, call 112.
Do not:
- Drive yourself
- Wait for the pain to become crushing
- Exercise to test whether the pain returns
- Assume relief with an antacid proves heartburn
- Assume tenderness proves muscle pain
- Assume fear or fast breathing proves panic
- Take someone else’s nitroglycerin
- Take aspirin before calling emergency services
- Use cough CPR
- Wait for every classic symptom
Emergency teams can monitor the heart, perform an ECG, begin treatment, and alert the hospital while traveling.
When Chest Pain Is an Emergency
Call emergency services for chest discomfort that:
- Feels like pressure, squeezing, tightness, heaviness, burning, or fullness
- Lasts more than a few minutes
- Goes away and returns
- Spreads to one or both arms, the shoulders, back, neck, jaw, or upper stomach
- Begins with activity or emotional stress
- Occurs at rest or wakes you from sleep
- Is new or different from your usual angina
Call immediately when chest discomfort occurs with:
- Shortness of breath
- Cold sweat
- Nausea or vomiting
- Lightheadedness
- Fainting
- Sudden weakness
- Unusual fatigue
- A rapid, slow, skipping, or irregular heartbeat
- Pale, blue, or gray skin or lips
- Confusion or collapse
A heart attack can be mild.
Do not wait for severe pain.
If the Person Becomes Unresponsive
If the person is unresponsive and not breathing normally:
- Call emergency services or send someone to call.
- Begin hands-only CPR.
- Push hard and fast in the center of the chest.
- Use an AED as soon as it is available.
- Follow the device and dispatcher instructions.
A heart attack and cardiac arrest are not the same.
A heart attack is a blood-flow problem.
Cardiac arrest is an electrical problem in which the heart stops pumping effectively.
A heart attack can lead to cardiac arrest.
What Is the Difference Between Chest Pain and a Heart Attack?
| Question | Chest pain | Heart attack |
|---|---|---|
| What is it? | A symptom with many possible causes | Heart-muscle injury caused by severely reduced or blocked blood flow |
| Can it be mild? | Yes | Yes |
| Can it feel like burning or indigestion? | Yes | Yes |
| Can it spread? | Some causes can spread | It may spread to arms, shoulders, back, neck, jaw, or upper stomach |
| Can it occur without obvious chest pain? | Not applicable | Yes |
| Can it be diagnosed by symptoms alone? | No | No |
| What tests may be needed? | Depends on the suspected cause | ECG, repeated troponin tests, examination, and other testing |
| What should you do when uncertain? | Seek urgent assessment for new or concerning symptoms | Call emergency services immediately |
This table is educational.
It cannot determine the cause of active chest pain.
What Heart-Attack Chest Pain May Feel Like
The most common description is discomfort in the center of the chest.
It may feel like:
- Pressure
- Squeezing
- Tightness
- Heaviness
- Fullness
- Burning
- A dull ache
- Indigestion
The discomfort may:
- Last more than a few minutes
- Go away and return
- Begin during activity
- Begin during emotional stress
- Occur at rest
- Wake the person from sleep
- Spread to one or both arms, shoulders, back, neck, jaw, or stomach
Not every heart attack feels dramatic.
A person may describe discomfort rather than pain.
Can a Heart Attack Happen Without Obvious Chest Pain?
Yes.
Possible symptoms without clear chest pain include:
- Shortness of breath
- Cold sweat
- Nausea or vomiting
- Jaw, neck, back, shoulder, arm, or upper-abdominal discomfort
- Sudden weakness
- Unusual fatigue
- Lightheadedness
- Fainting
- Palpitations
This may occur in any person.
Less obvious presentations are especially important in older adults and people with diabetes, kidney disease, or previous heart disease.
Do not wait for chest pain when other emergency signs are present.
Heart Attack Versus Angina
Angina is discomfort caused by insufficient oxygen-rich blood reaching heart muscle.
It is a symptom of coronary disease, not a harmless diagnosis.
Stable Angina
Stable angina often:
- Follows a predictable pattern
- Occurs with exercise, stress, cold weather, or a heavy meal
- Improves with rest or prescribed nitroglycerin
- Feels similar from episode to episode
First-time suspected angina needs medical evaluation.
Unstable Angina
Unstable angina is part of acute coronary syndrome and is an emergency.
Warning changes include:
- New chest discomfort
- More frequent episodes
- Longer or stronger episodes
- Symptoms with less activity
- Symptoms at rest
- Symptoms that do not improve as expected
A heart attack and unstable angina can feel the same.
The difference requires ECGs, troponin testing, and medical assessment.
Do not attempt to decide at home.
Heart Attack Versus Heartburn
GERD can cause burning behind the breastbone, regurgitation, sour taste, nausea, chest pain, and swallowing symptoms.
A heart attack may also feel like heartburn or indigestion.
Features that may accompany reflux include:
- A sour or bitter taste
- Regurgitation
- Symptoms after meals
- Symptoms when lying down
These clues do not prove the cause.
A heart attack remains concerning when symptoms:
- Are new or unusual
- Feel heavy, tight, squeezed, or pressured
- Spread to the arm, jaw, back, neck, or stomach
- Occur with breathlessness, sweat, nausea, faintness, or weakness
- Last more than a few minutes or return
Improvement after an antacid does not reliably exclude a heart attack.
Do not delay emergency care while testing an antacid.
Heart Attack Versus Muscle or Rib Pain
Muscle strain, rib injury, and costochondritis can cause:
- Localized pain
- Tenderness when pressing the area
- Pain that changes with movement
- Pain after lifting, coughing, exercise, or injury
- Pain that worsens with a deep breath
These patterns make a chest-wall cause more likely.
They do not guarantee that no heart or lung condition is present.
Seek urgent assessment when pain is:
- New or unexplained
- Severe or worsening
- Associated with breathlessness, sweating, nausea, weakness, or fainting
- Triggered by exertion
- Present with cardiovascular or clot risk
Heart Attack Versus Panic Attack
Panic can cause:
- Chest pain or tightness
- Rapid heartbeat
- Shortness of breath
- Sweating
- Trembling
- Dizziness
- Tingling around the mouth or fingers
- Fear or a sense of doom
A heart attack can also cause fear, breathlessness, sweating, nausea, and chest discomfort.
No single symptom safely separates the two.
A previous panic diagnosis does not prevent heart disease.
A first, severe, unusual, exertional, or persistent episode needs medical assessment.
Breathing exercises may support panic care after dangerous causes are excluded.
They should not delay an emergency call.
Other Life-Threatening Causes of Chest Pain
Pulmonary Embolism
A blood clot in the lung may cause:
- Sudden shortness of breath
- Chest pain worse with breathing
- Coughing blood
- A fast heartbeat
- Fainting or collapse
- One swollen, painful, red, or warm leg
Call emergency services.
Aortic Dissection
A tear in the aortic wall may cause:
- Sudden severe chest, back, neck, or abdominal pain
- Pain described as tearing or ripping
- Fainting
- Stroke-like symptoms
- A cold, weak, or painful limb
Call emergency services immediately.
Collapsed Lung
A pneumothorax may cause sudden one-sided sharp pain and shortness of breath.
It can happen after injury or without an obvious trigger.
Pericarditis and Myocarditis
Inflammation around or within the heart may cause chest pain, breathlessness, palpitations, fatigue, or fainting.
Pericarditis pain may worsen when lying down or breathing deeply and improve when sitting forward.
Symptoms require medical assessment.
Severe Infection
Pneumonia and other infections may cause chest pain, cough, fever, breathlessness, weakness, or confusion.
Severe breathing difficulty, blue lips, confusion, coughing blood, or rapid decline requires urgent care.
Women, Older Adults, Diabetes, Pregnancy, and Young Adults
Women
Chest discomfort is the most common heart-attack symptom in women and men.
Women may also experience:
- Shortness of breath
- Nausea or vomiting
- Back, shoulder, arm, jaw, or stomach discomfort
- Cold sweat
- Lightheadedness
- Unusual fatigue or weakness
Do not dismiss these symptoms as anxiety, menopause, reflux, or tiredness.
Older Adults and People With Diabetes
Symptoms may be less obvious.
Breathlessness, weakness, nausea, confusion, fainting, or sudden decline may be prominent.
Pregnancy and Postpartum
Chest pain or breathlessness during pregnancy or after birth can relate to:
- Pulmonary embolism
- Preeclampsia complications
- Peripartum cardiomyopathy
- Spontaneous coronary artery dissection
- Aortic disease
Call emergency services for sudden chest pain, severe breathlessness, fainting, coughing blood, or rapid deterioration.
Young and Fit Adults
Serious causes can still occur, including:
- Myocarditis
- Pericarditis
- SCAD
- Pulmonary embolism
- Pneumothorax
- Inherited heart disease
- Stimulant-related heart problems
Age and fitness do not replace assessment.
Aspirin and Nitroglycerin Safety
Call Before Taking Aspirin
The American Heart Association advises calling emergency services before doing anything else.
Do not take aspirin and wait for the pain to improve.
Aspirin is not appropriate for every person.
It may be unsafe with:
- Aspirin allergy
- Active bleeding
- Some bleeding disorders
- Previous instructions to avoid aspirin
- Some anticoagulant situations
- Suspected aortic dissection or another non-heart cause
Take aspirin only when the emergency dispatcher or a qualified professional says it is appropriate.
Use Only Your Prescribed Nitroglycerin
Use nitroglycerin only when:
- It was prescribed for you
- You follow your personal instructions
- You have not taken a medicine or substance that dangerously interacts with it
Call emergency services when symptoms are new, severe, different, or do not improve as expected.
Do not use someone else’s nitroglycerin.
How Doctors Diagnose Chest Pain and Heart Attack
The 2021 AHA and ACC chest-pain guideline recommends rapid evaluation for life-threatening causes and structured risk assessment.
History and Examination
The team assesses:
- Symptom timing and pattern
- Associated symptoms
- Heart and clot risk factors
- Vital signs and oxygen level
- Medicine and substance use
- Pregnancy or postpartum status
- Heart, lung, vascular, abdominal, and chest-wall findings
Electrocardiogram
An ECG should be obtained rapidly when acute coronary syndrome is suspected.
It may show a heart attack, reduced heart blood flow, pericarditis, or rhythm problem.
One normal ECG does not always rule out a heart attack.
Repeat ECGs may be needed.
High-Sensitivity Troponin
Troponin is released when heart muscle is injured.
High-sensitivity troponin is the preferred biomarker in current chest-pain evaluation.
Results are interpreted with:
- Symptoms
- ECG findings
- Time since symptoms began
- Repeat measurements
- Kidney function and other conditions
One early normal result may not be enough.
Chest Imaging
A chest X-ray may identify pneumonia, some pneumothoraces, heart enlargement, or other findings.
CT angiography may be used when pulmonary embolism or aortic disease is suspected.
Echocardiogram
An echocardiogram can assess:
- Heart pumping
- Wall-motion changes
- Valves
- Fluid around the heart
- Right-heart strain
Coronary Testing
Depending on risk, testing may include:
- Coronary CT angiography
- Stress imaging
- Coronary angiography
Low-risk patients may not need urgent cardiac testing after structured assessment.
The decision belongs to the clinical team.
How a Heart Attack Is Treated
The 2025 AHA and ACC acute coronary syndrome guideline guides current hospital care.
Treatment depends on:
- Heart-attack type
- ECG changes
- Troponin results
- Timing
- Bleeding risk
- Artery anatomy
- Age and other health conditions
Possible treatment includes:
- Antiplatelet medicine
- Anticoagulant medicine
- Medicine for symptoms or heart workload
- Urgent coronary angiography
- Balloon angioplasty
- Stent placement
- Coronary bypass surgery in selected cases
After the Emergency
Long-term treatment may include:
- Cardiac rehabilitation
- Cholesterol-lowering medicine
- Blood-pressure treatment
- Antiplatelet therapy
- Diabetes management
- Smoking cessation
- Activity and nutrition guidance
- Mental-health support
Do not stop heart medicine without advice.
Treatment for Other Causes of Chest Pain
Treatment must match the diagnosis.
GERD
After urgent causes are excluded, treatment may include:
- Smaller meals
- Avoiding personal triggers
- Not lying down soon after eating
- Clinician-recommended acid-reducing medicine
Persistent symptoms, swallowing problems, bleeding, or weight loss need evaluation.
Muscle Strain or Costochondritis
After serious causes are excluded, care may include:
- Temporary activity modification
- Gentle movement
- Protected heat or cold
- Clinician-approved pain medicine
- Physical therapy when needed
NSAIDs are not safe for every person.
Panic Disorder
Treatment may include:
- Education
- Psychological therapy
- Breathing and grounding skills
- Sleep support
- Medicine when appropriate
Pulmonary Embolism
Treatment commonly includes anticoagulants.
Severe cases may require advanced clot treatment, procedures, surgery, oxygen, or intensive care.
Pneumothorax
Treatment may involve observation, oxygen, aspiration, or a chest drain.
Pericarditis
Treatment may include clinician-directed anti-inflammatory medicine, colchicine, and treatment of the underlying cause.
Do not treat unknown chest pain at home.
How to Lower Heart-Attack Risk
Not every heart attack is preventable.
Risk reduction may include:
- Do not smoke or vape.
- Control blood pressure.
- Manage LDL cholesterol.
- Manage diabetes.
- Use prescribed medicine consistently.
- Use a heart-healthy eating pattern.
- Be physically active according to medical guidance.
- Treat sleep apnea.
- Limit or avoid alcohol.
- Maintain a healthy weight when appropriate.
- Avoid cocaine, amphetamines, and stimulant supplements.
- Attend follow-up after chest-pain evaluation.
- Use cardiac rehabilitation after a heart attack when referred.
Do not begin daily aspirin for prevention without professional advice.
Aspirin can cause serious bleeding.
Common Chest Pain and Heart Attack Myths
Myth: A Heart Attack Always Causes Crushing Pain
False. Symptoms may be mild, burning, intermittent, or mainly breathlessness, nausea, fatigue, or upper-body discomfort.
Myth: Heartburn Can Always Be Recognized
False. Heartburn and heart attack can feel similar.
Myth: Pain That Hurts When Pressed Cannot Be a Heart Attack
False. Tenderness suggests chest-wall pain but does not completely exclude another condition.
Myth: Sharp Pain Is Never Cardiac
False. Pain quality alone cannot safely rule out heart or lung disease.
Myth: A Panic Attack Is Easy to Distinguish
False. Panic and heart emergencies share many symptoms.
Myth: Women Do Not Usually Have Chest Pain
False. Chest discomfort remains the most common heart-attack symptom in women.
Myth: A Normal ECG Rules Out a Heart Attack
False. Repeat ECGs and troponin testing may be needed.
Myth: One Normal Troponin Always Rules It Out
False. Timing and repeat testing matter.
Myth: Aspirin Should Be Taken Before Calling
False. Call emergency services first.
Myth: You Should Drive to Save Time
False. Emergency teams can begin care and alert the hospital.
Myth: Cough CPR Can Stop a Heart Attack
False. Call emergency services. Use standard CPR only when the person is unresponsive and not breathing normally.
Conclusion
Chest pain vs heart attack cannot always be distinguished from symptoms alone.
Chest pain is a symptom with many possible causes.
A heart attack is one serious cause that requires immediate treatment.
Call emergency services for new, severe, persistent, spreading, exertional, or unexplained chest discomfort, especially with breathlessness, sweating, nausea, vomiting, dizziness, fainting, weakness, or an abnormal heartbeat.
Do not drive yourself.
Call before taking aspirin.
Use only your prescribed nitroglycerin as directed.
Do not rely on an antacid, tenderness, anxiety, pain location, age, a normal early ECG, or temporary improvement to rule out a heart attack.
Doctors use clinical assessment, ECGs, repeated high-sensitivity troponin tests, and targeted imaging to identify the cause.
When a heart attack is possible, immediate emergency assessment is safer than trying to compare symptoms at home.

Frequently Asked Questions
What is the difference between chest pain and a heart attack?
Chest pain is a symptom with many possible causes. A heart attack is heart-muscle injury caused by severely reduced or blocked blood flow.
How can I tell whether chest pain is a heart attack?
You may not be able to tell safely at home. Call emergency services for new, severe, persistent, spreading, exertional, or unexplained discomfort, especially with breathlessness, sweating, nausea, dizziness, weakness, or fainting.
What does heart-attack chest pain feel like?
It may feel like pressure, squeezing, tightness, heaviness, fullness, burning, indigestion, or discomfort that lasts or goes away and returns.
Can a heart attack happen without chest pain?
Yes. A person may mainly experience shortness of breath, nausea, sweating, unusual fatigue, weakness, dizziness, fainting, or pain in the jaw, back, arms, or upper stomach.
Can heartburn feel like a heart attack?
Yes. Both can cause burning, pressure, nausea, or indigestion-like discomfort. Relief from an antacid does not safely exclude a heart attack.
Can a panic attack feel like a heart attack?
Yes. Both can cause chest pain, breathlessness, sweating, dizziness, fear, and a rapid heartbeat. A first, severe, or unusual episode needs medical assessment.
Does chest tenderness rule out a heart attack?
No. Tenderness makes a chest-wall cause more likely, but it does not completely exclude heart or lung disease.
Should I take aspirin for possible heart-attack symptoms?
Call emergency services first. Take aspirin only when the dispatcher or a qualified health professional says it is safe and appropriate.
Should I use nitroglycerin for chest pain?
Use nitroglycerin only if it was prescribed for you and follow your personal instructions. Do not use another person’s medicine.
How do doctors diagnose a heart attack?
Doctors use symptoms, examination, ECGs, repeated high-sensitivity troponin tests, and other targeted tests or imaging.
Should I drive myself to the hospital?
No. Call emergency services when a heart attack is possible because emergency teams can monitor, treat, and alert the hospital while traveling.
