Key Takeaways
- Chest pain is the second most common reason for adults to visit an ER in the US, generating more than 6.5 million ER visits annually
- Only about 5% of patients presenting with chest pain will have an acute coronary syndrome (heart attack or unstable angina), according to the American Heart Association
- The most common causes of chest pain in outpatient settings are chest wall pain (20 to 50%), acid reflux (10 to 20%), and costochondritis (13%), per the American Academy of Family Physicians
- Imaging, most commonly an X-ray or ECG, followed by an echocardiogram if indicated, is the fastest way to narrow down the cause
- Urgent care is appropriate for mild to moderate chest symptoms; severe or rapidly escalating symptoms require the ER
- Primary care handles long-term management once an acute event is ruled out
- Women often present with atypical chest pain symptoms, including jaw pain, nausea, and unusual fatigue, that are more easily missed without proper imaging evaluation
Quick Overview: Chest pain and shortness of breath are among the most common and most misunderstood symptoms in medicine. Chest pain alone accounts for over 8 million emergency room visits in the US every year, yet research shows that only about 5% of those patients have an acute cardiac event. The rest have causes ranging from a muscle strain to acid reflux to pneumonia. Knowing what imaging is used to evaluate these symptoms and which setting to go to help you get the right answer without overtreating or underpreparing.

Why Chest Pain and Shortness of Breath Are Never Simple
Most people’s instinct when they feel chest pain is either to panic and go to the ER or to wait and hope it goes away. The problem with both responses is that the symptom itself tells you very little about severity. A heart attack and a pulled chest muscle can feel remarkably similar. Severe pneumonia and an anxiety attack can both cause shortness of breath that feels alarming.
This is precisely why imaging exists for these symptoms. The only reliable way to distinguish between a cardiac event, a lung condition, a gastrointestinal cause, or a musculoskeletal issue is to look inside.
Common Causes of Chest Pain and Shortness of Breath
Before understanding what imaging is used for, it helps to understand the range of conditions that produce these symptoms. The list is longer than most people realize.
Cardiac causes:
- Angina (reduced blood flow to the heart muscle during exertion)
- Acute myocardial infarction (heart attack)
- Pericarditis (inflammation of the sac around the heart)
- Heart failure with fluid backup into the lungs
- Arrhythmia causes the heart to pump inefficiently
Lung and respiratory causes:
- Pneumonia
- Pleuritis (inflammation of the lung lining)
- Pulmonary embolism (blood clot in the lungs)
- Asthma or COPD exacerbation
- Pneumothorax (collapsed lung)
- Pleural effusion (fluid around the lungs)
Gastrointestinal causes:
- Gastroesophageal reflux disease (GERD), which the American Heart Association identifies as one of the most common causes of non-cardiac chest pain
- Esophageal spasm
- Hiatal hernia
Musculoskeletal causes:
- Costochondritis (inflammation of the cartilage connecting the ribs to the sternum)
- Chest wall muscle strain
- Rib injury
Other causes:
- Anxiety or panic attacks
- Shingles (before the rash appears, the nerve pain can feel like chest pain)
- Anemia causing breathlessness
The reason imaging is so valuable here is that physical examination alone cannot reliably distinguish between these categories. A provider needs to see what is happening.
Which Imaging Tests Are Used for Chest Symptoms
Different tests answer different questions. Your provider will decide based on your symptoms, vital signs, physical exam, and medical history.
| Test | What It Evaluates | When It Is Used |
| Chest X-ray | Lungs, heart size, fluid, fractures | Almost always, the first step |
| ECG (electrocardiogram) | Heart’s electrical rhythm | Ordered alongside an X-ray for cardiac symptoms |
| Echocardiogram | Heart structure, valves, and pumping function | When a cardiac cause is suspected after X-ray/ECG |
| Holter monitor | Heart rhythm over 24 to 48 hours | For intermittent palpitations or arrhythmia |
| CT pulmonary angiography | Blood clots in the lungs (PE) | Typically ordered in the ER for suspected embolism |
| Ultrasound | Fluid around the heart or lungs | When an echocardiogram or a thoracic view is needed |
For most patients presenting to urgent care with chest symptoms, the evaluation begins with a chest X-ray and an ECG. Together, these two tests can identify pneumonia, fluid in the lungs, an enlarged heart, and the most common ECG patterns associated with cardiac events. If those results are concerning, the patient is referred to the ER. If they are normal but symptoms point toward a cardiac cause, an echocardiogram may be the next step.
What a Chest X-Ray Shows (and What It Does Not)
A chest X-ray is quick, widely available, and provides a significant amount of information. It can show:
- Lung infections such as pneumonia (as areas of haziness or consolidation)
- Fluid around the lungs (pleural effusion)
- Heart enlargement, which can suggest heart failure or hypertrophy
- Rib fractures or bony abnormalities of the chest wall
- Air in the pleural space (pneumothorax)
- Foreign objects
What it cannot show: the detailed internal function of the heart, soft tissue inflammation, a pulmonary embolism, or subtle airway changes. That is where additional tests come in.
An important point: a normal chest X-ray does not rule out a heart attack. The X-ray evaluates structure, not cardiac function or blood supply. This is why ECG and sometimes echocardiography follow when cardiac symptoms are present.
The Role of Echocardiography in Chest Symptom Evaluation
When a chest X-ray and ECG do not fully explain the symptoms, or when there is clinical concern about heart function specifically, an echocardiogram provides the next level of detail. It shows:
- How well the heart’s chambers are filling and contracting
- Whether any valves are leaking or narrowed
- The presence of fluid around the heart (pericardial effusion), which causes a distinctive pressure-type chest pain
- Regions of the heart that are not moving properly, which can indicate a previous or ongoing heart attack
- The ejection fraction, meaning how much blood the heart pumps per beat
In urgent care settings where echocardiography is available, this test can be done the same day and significantly shorten the diagnostic process. Without it, a patient might leave with “normal X-ray, normal ECG,” but still have an underlying cardiac issue that only an echo would reveal.
When Shortness of Breath Alone Requires Imaging
- Early-stage heart failure
- A pulmonary embolism
- Significant anemia
- Worsening asthma or COPD
- A developing pleural effusion
- Pneumonia with atypical presentation
A Note on Chest Pain in Women
The AHA guidelines specifically note that women often present with what are called “atypical” cardiac symptoms. This means their chest pain may not feel like the crushing, pressure-type sensation commonly associated with heart attacks. Women are more likely to describe:
- Jaw or upper back pain
- Unusual fatigue lasting for days
- Nausea or vomiting alongside chest discomfort
- Shortness of breath is the dominant symptom
These presentations are more easily attributed to anxiety, stress, or gastrointestinal causes, which can delay diagnosis. Imaging, particularly an ECG and echocardiogram, is essential for proper evaluation regardless of how symptoms present.
Urgent Care vs. ER for Chest Symptoms: A Practical Guide
This is the decision most patients struggle with. Here is a straightforward breakdown.
Go to urgent care when:
- Chest pain is mild to moderate and not rapidly worsening
- Pain appears linked to movement, breathing, or eating (suggesting musculoskeletal or GI origin)
- You want a same-day evaluation with X-ray and ECG without a multi-hour ER wait
- Symptoms have been present for a few days and are not escalating
- You have been evaluated before for similar symptoms and were told it was non-cardiac
Call 911 or go directly to the ER when:
- Chest pain is severe, crushing, or feels like pressure with squeezing
- Pain radiates to the left arm, jaw, neck, or upper back
- Symptoms are accompanied by sweating, nausea, or vomiting
- You feel faint, dizzy, or lose consciousness
- Shortness of breath is severe and coming on rapidly
- You have a known history of heart disease, and your symptoms feel different from usual
- You or someone else suspects a stroke (face drooping, arm weakness, speech difficulty)
An important note: if you drive yourself to urgent care and the provider believes your symptoms may be cardiac in nature, they will arrange immediate transport to the ER rather than sending you to drive yourself. The system is designed with escalation built in.
What Happens After Imaging for Chest Symptoms
- Results reviewed by the provider, usually within minutes for X-rays and ECGs in urgent care
- Three possible outcomes:
- Normal findings with a clear non-cardiac explanation: treatment begins in urgent care, and follow-up is scheduled with primary care
- Abnormal but non-emergent findings: treatment may begin in urgent care with a referral or follow-up arranged
- Findings suggesting a cardiac emergency: immediate transfer to the ER is arranged

FAQs:
Q1. Should I go to urgent care or the ER for chest pain?
It depends on severity. Mild to moderate chest pain with no radiating symptoms, sweating, or loss of consciousness can be evaluated at urgent care. Severe, sudden, or crushing pain with other symptoms warrants calling 911. When in doubt, err on the side of the ER.
Q2. Can urgent care diagnose a heart attack?
Urgent care can perform an ECG and chest X-ray to identify ECG patterns associated with heart attacks and rule out other causes. However, a definitive diagnosis of an acute heart attack typically requires cardiac enzyme blood tests and specialist evaluation. If a heart attack is suspected, you will be sent to the ER immediately.
Q3. Is shortness of breath always serious?
Not always, but it always warrants evaluation if it is new, worsening, or not explained by obvious physical exertion. It can signal anything from a mild respiratory infection to heart failure or a pulmonary embolism.
Q4. Can anxiety cause real chest pain?
Yes. Anxiety and panic attacks produce genuine physical chest tightness, palpitations, and shortness of breath through the body’s stress response. However, these symptoms should still be evaluated properly, because providers need to rule out cardiac and pulmonary causes before attributing symptoms to anxiety.
Q5. What does a normal chest X-ray mean?
A normal chest X-ray means the lungs and visible structures look structurally normal. It does not rule out a heart attack, arrhythmia, or early heart failure. Additional tests, such as an ECG and echocardiogram, may still be needed depending on your symptoms.
