ACUTE MYOCARDIAL-INFARCTION IN A HEALTHY MOTHER USING BROMOCRIPTINE FOR MILK SUPPRESSION

A 34-year-old mother developed acute myocardial infarction (MI) 10 pos tpartum while taking bromocriptine for ablactation. Her only known ris k factor was moderate hypercholesterolemia. The initial coronary arter iogram revealed minimal irregularities of the mid- and distal left ant erior descending (LAD) artery, but severe narrowing of a large first d iagonal branch of the LAD. Repeat coronary arteriography, performed tw o months later for recurrent chest pain, showed no significant change in the LAD. There was, however, a marked improvement in the first diag onal branch. To the authors' knowledge this is the 10th report of MI i n a patient using bromocriptine postpartum for milk suppression and on ly the second one to implicate by its investigations the role of vasos pasm in the coronary vessels as the cause of the infarction.
