Coronary spasm, variant angina, and recurrent myocardial infarctions

AD Johnson and JH Detwiler

A 24-year-old male student had three myocardial infarctions, one prior to and two following the angiographic documentation of normal coronary arteries. A spontaneous episode of variant angina prompted repeat coronary angiography, during which intravenous ergonovine caused spasm of the left anterior descending coronary artery, transient ST-segment elevation, and ischemic chest pain; the previously normal right coronary artery was found to be occluded proximally. This constellation of clinical and angiographic findings suggests that coronary spasm can cause acute myocardial infarction as well as variant angina.
