What Causes Chest Pain if the ECG is Normal?

An ECG rules out an immediate heart-related issue. A chest pain may be caused by factors unrelated to the heart, yet it creates anxiety and distress, making it essential to understand what other factors trigger it.

‍

Certain conditions of the lungs, digestive system, muscles, or stress also cause chest pain. It is thus necessary to stay informed about these non-cardiac causes.

‍

Young adults often complain of chest pain, but is it a heart problem? The blog guides you through the various causes of chest pain even when the ECG results are normal, helping you recognise symptoms, assess risks, and seek care.

The Location of Chest Pain Matters

A chest pain makes you wonder why it is hurting. Pain on the right side or middle of your chest can make you think of a heart attack. The location of the chest pain matters.

‍

Sometimes people have silent heart attacks, with no pain. Pain during a heart attack in the chest spreads to the size of a fist and can be experienced in other areas of the body. It is referred to as pain, which occurs in.

‍

• Neck or throat.

• Shoulders.

• Upper back between your shoulder blades.

• Left or right side of the jaw.

• Left or right mid to upper arms.

‍

Symptoms of Chest Pain

Heart attack-related chest pain comes suddenly and doesn’t go away on its own. Heart attack  symptoms are.

‍

• Shortness of breath.

• Fatigue.

• Lightheadedness or dizziness.

• Racing heart.

• Cold sweat.

• Chest pain.

• Loss of consciousness.

‍

Ruling out a Heart Attack

Not all chest pains raise alarm bells for a heart attack, and not all people who have complaints of chest pain have heart-related reasons. Look for answers to the following questions: If the pain is momentary.

‍

• Do you experience pain in an isolated, small area.

• Does it get worse or better with the change of possession of the body.

‍

A sudden, sharp, momentary chest discomfort that lasts for a few minutes could result from.

‍

• An injury, such as broken ribs.

• A muscle pull in the chest region.

• Inflammation of the rib cartilage.

• Fibromyalgia.

• Shingles.

‍

A sharp pain in the chest that gets worse on moving or taking deep breaths is not a heart attack, and could have a lung-related cause.

‍

• Pneumonia.

• Pleurisy inflammation of the lining of the lungs.

• A blood clot in the lungs.

• Asthma.

‍

Diagnostic Steps Following a Normal ECG

When we have an unexplained chest pain and a normal ECG, we need a follow-up with additional diagnostic tests that help us diagnose the cause.

‍

Blood test

Blood tests assess markers indicating inflammation or other abnormalities within different organs, such as:

‍

• Liver function test.

• Thyroid profiles.

• Troponin levels.

‍

These may be checked after an initial ECG appears normal, and elevated levels are used to evaluate cardiac damage.

‍

Imaging test

Imaging studies helped us to distinguish various types of chest pains.

‍

• Chest x-ray, the imaging techniques help us to visualise lung conditions such as pneumonia, pleural effusion.

• A CT scan offers images that help us to identify vascular issues like pulmonary embolism or aortic dissection.

• An echocardiogram is an ultrasound of the heart. It reveals the heart structure and function to rule out abnormalities.

• Endoscopy: When GI issues are suspected, it helps us see the esophageal tract for diagnosis. 

‍

These diagnostic tools assist healthcare professionals in pinpointing the cause of the chest pain.

‍

Causes of Chest Pain

‍

Angina Pectoris

Angina is a chest pain that occurs when the heart does not get enough oxygen, and is triggered by physical exertion or stress. It is felt as chest tightness that spreads down towards the arm or up towards the chin. Chest pain caused by non-cardiac reasons is due to.

‍

Musculoskeletal issues

Musculoskeletal problems are the common non-cardiac causes of chest pain. Costochondritis muscle strain leads to discomfort in the chest. It is inflammation of cartilage connecting the rib to the sternum, which causes a sharp or aching pain that may worsen with movement or pressure. Muscle strain occurs from.

‍

• lifting heavy objects.

• engaging in strenuous activity.

‍

The pain is localised and improves with rest or anti-inflammatory drugs.

‍

Anxiety and panic attacks

Anxiety causes chest pain. Individuals who experience high levels of stress on panic attacks feel chest pain that mimics cardiac symptoms.

‍

It occurs due to:

• Hyperventilation.

• Muscle tension.

• Increased adrenaline levels during stressful episodes.

‍

The sensations resolve once the symptoms subside.

‍

Gastrointestinal problems

Gastrointestinal (GI) issues also cause chest discomfort and present as chest pain. It is essential to identify these GI-related causes, which are.

‍

• Gastroesophageal reflux disease (GERD) occurs when acid produced in the stomach flows back into the oesophagus. It causes burning sensations in the chest, which can be easily mistaken for heart-related symptoms.

• Esophageal spasms cause irregular contractions that cause discomfort similar to angina.

• Gastritis is inflammation of the stomach lining.

‍

Pulmonary conditions

Pulmonary conditions that cause chest pain are:

‍

• Pneumonia has symptoms like fever and cough, and localised chest discomfort. 

• Inflammation of the  Pleura (Pleurisy), the membrane surrounding the lungs, causes sharp pain during inhalation or coughing.

‍

Less common causes of chest pain are.

‍

Shingles

Shingles are caused by reactivation of the varicella-zoster virus, which causes chickenpox, causes shingles. It is experienced as a localised burning or tingling sensation in the area before a rash appears. If shingles affects nerves near the chest wall, it causes discomfort mimicking cardiac symptoms.

‍

Aortic dissection

Though rare, aortic dissection occurs when a tear in the inner layer of the aorta’s wall develops, causing severe pain, a tearing or ripping sensation in the back or chest. It is life-threatening, followed by sudden severe chest pain, fainting, or difficulty in breathing.

‍

Lifestyle Changes to Prevent Chest Pain

Heart disease is one of the leading causes of death globally. Adopting healthy habits can significantly reduce the risk of developing chest pain, both due to cardiac and non-cardiac causes. The lifestyle changes that you can make are.

‍

1. Take a balanced diet: A balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats is essential for health. These foods have essential nutrients and antioxidants. Limit intake of saturated fats, trans-fats, sodium, and added sugars. Avoid fried food and opt for baked, grilled, or steamed food.

‍

2. Engage in regular physical activity: Doing regular exercise, 150 minutes of moderate intensity exercise or 75 minutes of vigorous exercise a week, lowers blood pressure and improves cholesterol.

‍

3. Maintain a healthy weight: A healthy weight reduces the strain on the body and lowers the risk of diseases.

‍

4. Reduce stress: Stress is responsible for our adopting unhealthy habits as smoking, overeating, and drinking. Practice relaxation techniques and make time for friends and family.

‍

Treatment for Non-cardiac Chest Pain

Non-cardiac chest pain is treated by treating the underlying cause.

‍

• Antacids, proton pump inhibitors (PPIs), muscle relaxants, and anti-inflammatory medications treat chest pain related to gastric disorders.

• Diet changes and physical therapy improve muscle function.

• Doing meditation and yoga relieves stress, anxiety, and panic attacks.

• Doing a nerve block on the inflamed nerves relieves chest pain.

• Severe gastroesophageal issues or musculoskeletal problems are relieved by surgery.

‍

Medical interventions, lifestyle adjustments, and other therapies help to manage symptoms and improve the quality of life.

‍

‍

It is important not just for peace of mind, but also to catch any serious health issues.

Conclusion

A normal ECG doesn’t exclude chest pain. It rules out serious heart issues like heart attacks. Other conditions like acid reflux, muscle strain, anxiety, or lung problems also cause chest pain.
