Gastroesophageal Reflux Disease (GERD) is a frequent cause of non-cardiac chest pain. Your history-taking is the most powerful tool to differentiate it from cardiac pain. Look for these key features:
- Quality: Patients often describe the pain as "burning" or "sour," rather than "pressure" or "squeezing."
- Provoking/Palliating Factors: Pain is often worse after large or spicy meals, and when lying down (supine). It is often relieved by antacids.
- Associated Symptoms: Ask about a sour taste in the mouth (regurgitation), bloating, or difficulty swallowing (dysphagia).
