Chest Pain: What It Means, Common Causes, and How It's Treated

What is Chest Pain?

Chest pain includes any discomfort experienced in the area between your neck and upper abdomen. This sensation can manifest in various ways, from a dull ache to sharp, stabbing pain or crushing pressure that feels overwhelming.

The nature of chest pain varies significantly depending on its underlying cause. You might experience chest muscle pain from physical strain, or more concerning symptoms that signal serious medical conditions. Understanding these differences is essential for determining when to seek medical attention.

Chest pain can originate from multiple sources within your chest cavity, including your heart, lungs, digestive system, or musculoskeletal structures. The location, intensity, and accompanying symptoms provide valuable clues about the underlying chest pain causes.

Common Causes of Chest Pain

Heart-related conditions:

• Heart attack (myocardial infarction)
• Angina (reduced blood flow to the heart muscle)
• Myocarditis (inflammation of the heart muscle)
• Pericarditis (inflammation of the heart's protective lining)
• Aortic dissection (tear in a major artery)
• Arrhythmias (irregular heart rhythms)

Lung-related conditions:

• Pulmonary embolism (blood clot in lungs)
• Pneumothorax (collapsed lung)
• Pneumonia or lung infections
• Pleuritis (inflammation of the lung lining)
• Asthma exacerbations
• Chronic obstructive pulmonary disease (COPD)

Gastrointestinal causes:

• Gastroesophageal reflux disease (GERD) causing gastric pain in the chest
• Oesophageal spasms
• Gallstones
• Stomach ulcers
• Gastritis
• Pancreatitis

Musculoskeletal causes:

• Costochondritis (rib cartilage inflammation)
• Muscle strain from exercise or injury
• Rib fractures
• Nerve inflammation in the chest wall

Other common causes:

• Anxiety and panic attacks
• Shingles (herpes zoster)
• Chest pain due to COVID-related complications

Heart Attack and Chest Pain: Symptoms to Watch For

Heart attack chest pain typically presents as an intense pressure, squeezing, or crushing sensation in the center of the chest or left-sided chest pain. The pain frequently radiates beyond the chest area, spreading to your jaw, shoulder, arm, or back.

Unlike other chest pain symptoms, heart attack pain persists for more than 15 minutes and doesn't improve with rest or position changes. You might also experience shortness of breath, nausea, dizziness, excessive sweating, and an irregular heartbeat that deviates from your normal heart rate.

Women may experience different symptoms, including unusual fatigue, chest pain when breathing becomes laboured, or pain in the middle of the chest that feels less intense than the classic crushing sensation.

How Dopamine Affects Chest Pain

Dopamine, a crucial neurotransmitter, helps regulate heart rate, blood pressure, and overall cardiac output — influencing how your body responds to different causes of chest pain.

In medical emergencies, doctors sometimes use dopamine medications to support heart function, particularly when patients have low blood pressure or acute heart failure. However, dopamine imbalances can affect heart rhythm and potentially alter your perception of chest pain symptoms.

Research suggests that dopamine also influences pain modulation pathways in your brain, potentially affecting how you experience chest muscle pain or other discomfort.

How Chest Pain is Diagnosed

Doctors use a systematic approach to identify potential chest pain causes and determine the urgency of your situation:

• Detailed medical history: Your doctor will ask about pain characteristics—onset, duration, quality, location, radiation, and what makes it better or worse.
• Physical examination: Assessment of vital signs, heart sounds, lung sounds, and chest wall tenderness.
• Risk factor evaluation: Review of family history, lifestyle factors, existing medical conditions, and medications.
• Symptom analysis: Discussion of associated symptoms like shortness of breath, nausea, or sweating.
• Timeline assessment: Understanding when symptoms occur and their relationship to activities or stress.

Medical and Imaging Tests for Diagnosing Chest Pain

The selection of tests required for diagnosis depends on your symptoms, risk factors, and initial examination findings.

• Electrocardiogram (ECG): Records the heart’s electrical activity to detect abnormal rhythms or evidence of a heart attack.
• Blood tests: Cardiac enzymes (such as troponin I – serum), inflammatory markers (C-reactive protein [CRP], interleukin-6 [IL-6], and TNF-α), and D-dimer for blood clots.
• Chest X-ray: Assesses lung condition, heart size, and identifies pneumonia, pneumothorax, or fractures.
• Echocardiogram: Uses ultrasound to assess heart structure and pumping function.
• Stress testing: Monitors heart performance during controlled exercise or medication-induced stress.
• CT scan: Provides detailed images for aortic dissection, pulmonary embolism, or other conditions.
• MRI: Offers comprehensive soft tissue evaluation when indicated.
• Coronary angiography: Visualizes the coronary arteries to identify blockages that may require intervention.

These tests help differentiate between chest pain in the left side from heart problems, right side chest pain from lung issues, or pain in the middle of the chest from digestive causes.

Treatment for Chest Pain

Treatment approaches vary significantly based on the underlying chest pain and the severity of your condition. Emergency situations require immediate intervention, while other conditions may need ongoing management.

1. Emergency stabilisation: For life-threatening conditions, immediate interventions may include oxygen therapy, pain-relief medications (such as nitroglycerin or morphine), aspirin administration, or advanced life support measures.
2. Medication management: Heart-related causes may require antiplatelet drugs, blood thinners, beta-blockers, or ACE inhibitors. Infections need appropriate antibiotics, while digestive causes respond to antacids or acid-blocking medications.
3. Procedural interventions: Severe coronary blockages may require angioplasty or bypass surgery. Pneumothorax might need chest tube placement, while pulmonary embolism could require clot-dissolving therapy.
4. Lifestyle modifications: Smoking cessation, blood pressure control, cholesterol management, and dietary improvements form the foundation of long-term cardiovascular health.
5. Targeted therapy: Chest muscle pain often responds to anti-inflammatory medication and physiotherapy, while anxiety-related chest pain may benefit from counseling or anti-anxiety medication.

Chest Pain and Heart Attack: Key Differences

When to Seek Emergency Help for Chest Pain

The American Heart Association emphasises that every minute counts during a heart attack, as delayed treatment increases heart muscle damage. Call emergency services immediately if you experience:

• Sudden, severe chest pain with shortness of breath
• Chest pain left side radiating to the arm, jaw, or back.
• Crushing or squeezing sensation in the chest
• Chest pain with sweating, nausea, or dizziness
• Pain in the middle of the chest that does not improve with rest
• Chest pain when breathing, combined with leg swelling or cough

Seek urgent medical care for:

• New chest pain with a history of heart disease
• Chest pain following physical trauma
• Persistent right-sided chest pain with fever
• Any chest pain that concerns you, especially with risk factors

The Role of Dopamine in Heart Disease

Dopamine significantly influences cardiovascular health through its effects on heart rate, blood pressure, and cardiac output. In healthy individuals, dopamine helps maintain proper circulation and supports normal heart rate regulation.

Here are the key dopamine effects on the cardiovascular system:

• Blood pressure regulation through vascular tone control
• Heart rate modulation during stress responses
• Influence on stress-related chest pain symptoms
• Impact on medication effectiveness in heart failure patients

Research indicates that dopamine imbalances may contribute to stress-induced chest pain, particularly in individuals with anxiety disorders. When dopamine signalling becomes disrupted, your body's stress response can trigger chest pain symptoms that mimic cardiac conditions, leading to confusion about actual causes.

Lifestyle Changes to Prevent Chest Pain

Adopting heart-healthy habits significantly reduces your risk of developing various causes and improves overall cardiovascular health. These preventive measures are particularly important if you have risk factors for heart disease.

Essential lifestyle modifications include:

• Regular physical activity (at least at least 150 minutes of moderate exercise each week)
• Balanced nutrition that emphasizes fruits, vegetables, whole grains, and lean proteins
• Complete tobacco cessation and avoiding second-hand smoke exposure
• Maintaining a healthy weight and preventing obesity
• Stress management through relaxation techniques, meditation, or counseling
• Controlling chronic conditions like diabetes, high blood pressure, and high cholesterol
• Limiting alcohol consumption to recommended guidelines
• Getting adequate sleep (7-9 hours nightly for most adults)
• Regular medical check-ups for early detection and management of risk factors

These lifestyle modifications work together to reduce inflammation, improve circulation, maintain a normal heart rate, and decrease overall cardiovascular risk.
