Esophageal angina, mimicking cardiac chest pain, is common in patients with clear coronary arteries. Diagnosis requires certainty, utilizing pH monitoring and provocative tests for accurate identification.

Area of Science:

  • Gastroenterology and Cardiology
  • Esophageal Physiology
  • Pain Mechanisms

Context:

  • Angina-like chest pain is frequently encountered by cardiologists.
  • A significant portion of patients with normal coronary angiograms experience esophageal angina.
  • Esophageal causes are often overlooked in the differential diagnosis of chest pain.

Purpose:

  • To elucidate the prevalence and diagnostic challenges of esophageal angina.
  • To explore the underlying pathophysiological mechanisms of esophageal chest pain.
  • To highlight the importance of accurate diagnosis and comprehensive patient evaluation.

Summary:

  • Esophageal angina, characterized by chest pain due to esophageal dysfunction, affects a substantial number of patients with normal coronary arteries.

  • Pathological gastro-esophageal reflux and esophageal motility disorders are primary causes, with potential roles for chemosensitive receptor activation, mechanoreceptor stimulation, and esophageal ischemia.
  • Accurate diagnosis necessitates definitive testing, including prolonged pH monitoring and provocative maneuvers like balloon distension and edrophonium testing, alongside prolonged manometry.
  • Psychological factors can also contribute to the genesis of esophageal pain, underscoring the need for a holistic patient assessment.

    • Impact:

    • Improves diagnostic accuracy for non-cardiac chest pain, reducing unnecessary cardiac investigations.
    • Enhances understanding of esophageal pain mechanisms, paving the way for targeted therapies.
    • Promotes a multidisciplinary approach to chest pain management, integrating gastroenterological and cardiological perspectives.
    • Aims to achieve diagnostic certainty, crucial for appropriate patient management and prognosis.
