Spontaneous coronary artery dissection in an elderly woman with acute inferior myocardial infarction. A case report.
Spontaneous coronary artery dissection is a rare cause of acute myocardial infarction. It usually occurs in relatively young patients and is frequently found at autopsy. Because of the low incidence, the treatment of choice for spontaneous coronary artery dissection is still not settled. Here the authors report a sixty-six-year-old woman with coronary lesions judged as spontaneous coronary artery dissection. She presented with chest pain. Under diagnosis of acute inferior myocardial infarction, she was treated with recombinant tissue-type plasminogen activator. Coronary arteriography performed two weeks later revealed a dissection involving a long segment of right coronary artery. The left coronary arteries and uninvolved portion of right coronary artery were smooth and patent. She suffered no hypertension and gave no definite history of trauma. This patient was treated medically with aspirin, isosorbide dinitrate, and metoprolol and remained in stable condition after a follow-up period of six months.
