title: Acute myocardial infarction presenting with pharyngeal pain alone.
abstract: BACKGROUND
  Pharyngeal pain alone due to acute myocardial infarction is rare.
  
  
  METHODS
  A 37-year-old man felt sudden pharyngeal pain. He was transferred to a medical facility under a misdiagnosis of pharyngitis. However, he was thereafter found to have acute myocardial infarction and thus was transferred to another hospital. An emergency coronary angiogram revealed complete occlusion of the right coronary artery and he underwent coronary angioplasty. The patient was later discharged ambulatory.
  
  
  CONCLUSIONS
  A misdiagnosis of acute myocardial infarction can lead to unfavorable outcomes; therefore, physicians or emergency medical technicians should be aware of this disease even when a patient complains of sudden pharyngeal pain alone.
