What is center chest pain not cardiac? Common causes explored

3 min read

Millions of people present to emergency rooms with chest pain, but the majority of these cases are not heart-related. Understanding what is center chest pain not cardiac is the first step toward finding relief and addressing the underlying issue.

Quick Summary

Non-cardiac chest pain, or NCCP, is recurrent chest pain that mimics heart-related pain but is actually caused by issues with the esophagus, musculoskeletal system, lungs, or psychological factors like anxiety.

Key Points

Initial Action: Always assume chest pain is cardiac until a medical professional confirms otherwise and seek emergency care if symptoms are severe.
NCCP Explained: Non-cardiac chest pain is recurrent chest pain not caused by heart disease but can mimic it due to shared nerve pathways.
Key GI Causes: Conditions like GERD, esophageal spasms, and gallbladder issues are frequent non-cardiac culprits.
Musculoskeletal Origin: Pain from costochondritis or a strained chest muscle often worsens with pressure or movement.
Psychological Component: Anxiety and panic attacks are significant causes of chest tightness and discomfort.
Diagnosis by Exclusion: A non-cardiac cause is diagnosed after cardiac conditions and other serious issues are ruled out through testing.

What Exactly Is Non-Cardiac Chest Pain?

Non-cardiac chest pain (NCCP) refers to chest discomfort that is not caused by heart disease. While it can feel and behave like angina, it originates from other bodily systems. A key reason for the confusion is that the heart and the esophagus are located close together in the chest cavity and share the same sensory nerves. This means the brain can have difficulty distinguishing between pain signals from these different organs, leading to a sensation that feels like it's coming from the heart, even when it isn't.

Common Causes of Non-Cardiac Chest Pain

Once serious cardiac conditions have been ruled out, a healthcare provider will investigate other potential causes. The most common origins of NCCP are gastrointestinal, musculoskeletal, and psychological.

Gastrointestinal Causes

Gastroesophageal Reflux Disease (GERD): This is the most common cause of NCCP. It occurs when stomach acid flows back into the esophagus, irritating the lining and causing a burning sensation known as heartburn. This pain is often felt behind the breastbone and can be mistaken for a heart attack, especially if it intensifies after eating or when lying down.
Esophageal Spasms: These are abnormal contractions of the muscles in the esophagus, which can cause intense, squeezing chest pain that may feel identical to a heart attack. The spasms are often triggered by swallowing food or drink.
Esophageal Hypersensitivity: In some people, the nerves in the esophagus are overly sensitive to small changes in pressure or acid, causing them to perceive normal sensations as pain.
Other GI Issues: Problems with the gallbladder, pancreas, or stomach (like gastritis or ulcers) can cause referred pain that is felt in the center of the chest.

Musculoskeletal Causes

Costochondritis: An inflammation of the cartilage that connects a rib to the breastbone. This can cause sharp, localized pain that worsens when you press on the area or move your torso.
Muscle Strain: Straining chest wall muscles from strenuous exercise, heavy lifting, or a persistent cough can lead to soreness and discomfort that radiates to the chest center.
Fibromyalgia: This chronic condition can cause widespread pain, including in the chest area, and is often accompanied by fatigue and sleep problems.

Pulmonary (Lung-Related) Causes

Pleurisy: Inflammation of the tissue lining the lungs and chest cavity. It causes a sharp, stabbing pain that typically worsens with deep breathing or coughing.
Pneumonia: A lung infection that can cause chest pain along with fever, cough, and shortness of breath.
Asthma: Severe asthma attacks can sometimes present with chest tightness and pain.

Psychological Causes

Anxiety and Panic Attacks: These conditions can manifest as intense physical symptoms, including chest tightness, shortness of breath, and chest pain, which are easily mistaken for a heart attack.
Stress: High levels of stress can cause muscle tension and affect the nervous system, leading to chest discomfort.

Diagnosing Non-Cardiac Chest Pain

Since differentiating between cardiac and non-cardiac pain is difficult without medical expertise, the diagnostic process always begins with ruling out heart-related issues. This typically involves:

Cardiac Evaluation: Initial tests, such as an electrocardiogram (EKG) and blood work, to assess heart health and rule out conditions like a heart attack.
Gastrointestinal Tests: If cardiac issues are excluded, an upper endoscopy or esophageal manometry may be used to examine the esophagus and measure its muscle function.
Imaging: Chest X-rays or CT scans can help identify lung problems or other structural issues.
Psychological Assessment: Evaluation by a mental health professional can help determine if anxiety or stress is a contributing factor.

Comparative Table: Cardiac vs. Non-Cardiac Chest Pain


Feature	Cardiac Chest Pain (Angina)	Non-Cardiac Chest Pain (NCCP)
Sensation	Crushing pressure, squeezing, or heaviness.	Sharp, burning, or stabbing pain.
Location	Often radiates to the left arm, jaw, or neck.	Typically localized to the center of the chest but can spread.
Triggers	Exertion, stress, large meals.	Eating, swallowing, stress, specific movements.
Duration	Lasts a few minutes, relieved by rest or medication (nitroglycerin).	Varies widely, from seconds to hours; may not be relieved by typical cardiac meds.
Associated Symptoms	Sweating, shortness of breath, nausea.	Heartburn, difficulty swallowing, tenderness to the touch.

Conclusion

While a symptom like center chest pain can be alarming, a thorough medical evaluation is the only way to determine its origin. After cardiac causes are excluded, a wide range of non-cardiac issues, from GERD to musculoskeletal problems, can be responsible. Accurate diagnosis is essential for effective treatment and peace of mind. For more information on general health topics, consult reliable sources such as the National Institutes of Health.

Frequently Asked Questions

You cannot definitively tell yourself. Medical evaluation is crucial to rule out heart disease first, as many non-cardiac conditions can mimic heart pain due to shared nerve pathways. A doctor will perform tests to determine the cause.

The most common causes include gastroesophageal reflux disease (GERD), musculoskeletal problems like costochondritis, and psychological factors such as anxiety or panic attacks.

Yes, anxiety and panic attacks are well-known causes of chest pain. They can induce physical symptoms like chest tightness and a rapid heart rate, which can be mistaken for a heart problem.

After ruling out cardiac issues with tests like an EKG, doctors may use procedures like an upper endoscopy or esophageal manometry to check for digestive or esophageal problems. Imaging can also help identify lung problems.

Some indicators of non-cardiac pain include: it's less likely to be accompanied by sweating or shortness of breath, it might change with pressure or position (suggesting a musculoskeletal cause), or it may be related to eating (suggesting a GI issue).

Yes, conditions like GERD, gastritis, or issues with the gallbladder and pancreas can cause pain that radiates to the center of the chest, mimicking heart pain due to shared nerves.

Treatment is specific to the underlying cause. Options can include acid-blocking medications for GERD, anti-inflammatory drugs for musculoskeletal pain, or counseling and stress management for anxiety-related pain.
