title: A case of cardiac cephalalgia showing reversible coronary vasospasm on coronary angiogram.
abstract: BACKGROUND
  Under certain conditions, exertional headaches may reflect coronary ischemia.
  
  
  METHODS
  A 44-year-old woman developed intermittent exercise-induced headaches with chest tightness over a period of 10 months. Cardiac catheterization followed by acetylcholine provocation demonstrated a right coronary artery spasm with chest tightness, headache, and ischemic effect of continuous electrocardiography changes. The patient's headache disappeared following intra-arterial nitroglycerine injection.
  
  
  CONCLUSIONS
  A coronary angiogram with provocation study revealed variant angina and cardiac cephalalgia, as per the International Classification of Headache Disorders (code 10.6). We report herein a patient with cardiac cephalalgia that manifested as reversible coronary vasospasm following an acetylcholine provocation test.
