title: Myocardial infarction associated with intravenous immune globulin.
abstract: OBJECTIVE
  To report a case of acute myocardial infarction (MI) experienced by a patient receiving intravenous immune globulin (IVIG) and review other published cases of MI associated with IVIG.
  
  
  METHODS
  An 81-year-old Vietnamese man was prescribed IVIG for treatment of toxic epidermal necrolysis secondary to allopurinol. Thirty minutes following the start of the IVIG infusion, the patient developed crushing retrosternal chest pain and shortness of breath. The pain improved upon discontinuation of IVIG infusion but recurred when IVIG was restarted. The troponin level reached 140 microg/L, and a persantine sestamibi stress test (MIBI) indicated anterolateral ischemia. The patient was diagnos ed with non-ST-elevation MI. An objective causality assessment using the Naranjo probability scale revealed a probable association between this adverse reaction and IVIG treatment.
  
  
  CONCLUSIONS
  Although an association between IVIG administration and MI has not been demonstrated in clinical trials, accumulating clinical experience suggests that a relationship between IVIG and myocardial ischemia exists. Twenty published case reports were identified. Risk of acute MI seems to be increased with use of high-dose IVIG and in older individuals, especially those with at least one cardiovascular risk factor, such as ischemic heart disease or hypertension.
  
  
  CONCLUSIONS
  Case reports suggest a causal relationship between the use of IVIG and MI and other thrombotic events. While cardiovascular disease is not considered an absolute contraindication to therapy, expanding indications and subsequent use of IVIG merit that clinicians be aware of patient characteristics that may increase the risk for adverse reactions and recognize early signs of infarction.
