What are possible causes of recurrent chest pain, pressure, and dizziness in a patient with negative cardiac testing (blood work, stress electrocardiogram, MRI) after alcohol consumption?

Gastroesophageal Reflux Disease (GERD) is the Most Likely Cause

Your chest pain, pressure, and dizziness with negative cardiac workup most likely represents gastroesophageal reflux disease (GERD), which accounts for approximately 30% of recurrent non-cardiac chest pain cases. 1

Why GERD is the Primary Diagnosis

The clinical picture strongly suggests GERD for several reasons:

• Negative cardiac testing rules out acute coronary syndrome: Your blood tests, stress ECG, and MRI have excluded heart attack and significant cardiac pathology
• GERD causes angina-like chest pain: The guideline evidence confirms that in patients with non-cardiac chest pain, 21-42% have abnormal acid exposure, and 39% show positive association between chest pain and reflux episodes during pH monitoring 1
• Alcohol is a known trigger: Alcohol consumption commonly precipitates or worsens GERD symptoms, which aligns with your initial presentation after drinking

The Alcohol Connection

While alcohol can cause direct cardiac effects (coronary spasm 2, ECG changes 3, cardiomyopathy 4), your negative cardiac testing makes these unlikely. Instead, alcohol likely:

• Relaxes the lower esophageal sphincter, allowing acid reflux
• Increases gastric acid production
• Initially triggered symptoms that have now become chronic GERD (symptoms lasting >6 months support GERD diagnosis 1)

Addressing the Dizziness

The dizziness component warrants consideration of two mechanisms:

1. Orthostatic hypotension from alcohol: Alcohol blunts sympathetic responses to postural changes and can cause blood pressure drops 5, though this typically occurs during/shortly after drinking
2. Vasovagal response to chest discomfort: GERD-related chest pain can trigger vagal responses causing lightheadedness
3. Anxiety related to chest symptoms: Fear of cardiac events can produce dizziness

Recommended Diagnostic and Treatment Algorithm

Step 1: Empiric PPI Trial (Most Important)

• Start a proton pump inhibitor (omeprazole 20-40mg daily or esomeprazole 40mg daily) for 8 weeks
• This serves as both diagnostic test and treatment
• Response to PPI therapy strongly supports GERD diagnosis 1

Step 2: Lifestyle Modifications

• Complete alcohol cessation (at minimum during diagnostic period)
• Avoid late-night eating (stop 3 hours before bed)
• Elevate head of bed 6-8 inches
• Avoid trigger foods (caffeine, chocolate, fatty foods, citrus)

Step 3: If No Response to PPI

• Consider upper endoscopy to evaluate for esophagitis, Barrett's esophagus, or alternative diagnoses
• 24-hour pH monitoring can definitively establish acid reflux
• Consider esophageal manometry if dysphagia develops

Critical Pitfalls to Avoid

⚠️ Do not dismiss ongoing symptoms without PPI trial: Many patients with GERD have normal endoscopy but still have acid-related symptoms

⚠️ Monitor for alarm symptoms: New dysphagia (difficulty swallowing), unintentional weight loss, or persistent vomiting require urgent endoscopy to exclude malignancy 1

⚠️ Don't assume cardiac clearance is permanent: If symptoms change character (become exertional, radiate to jaw/arm, or are associated with shortness of breath), repeat cardiac evaluation

Alternative Considerations (Less Likely)

Given negative cardiac testing, other possibilities include:

• Esophageal motility disorders: Would require manometry for diagnosis
• Musculoskeletal chest wall pain: Usually reproducible with palpation
• Anxiety/panic disorder: Can cause chest pressure and dizziness, but typically with hyperventilation

The evidence strongly supports starting empiric PPI therapy immediately while maintaining alcohol abstinence, with expectation of symptom improvement within 2-4 weeks if GERD is the cause.
