Transmural myocardial infarction with sumatriptan.
For sumatriptan, tightness in the chest caused by an unknown mechanism has been reported in 3-5% of users. We describe a 47-year-old woman with an acute myocardial infarction after administration of sumatriptan 6 mg subcutaneously for cluster headache. The patient had no history of underlying ischaemic heart disease or Prinzmetal's angina. She recovered without complications.
