Leukocytosis: a risk factor for myocardial infarction

Suman K KotlaDepartment of Internal Medicine, Memorial Medical Center, Johnstown, PA, USAAbstract: Myocardial infarction commonly results from atherosclerotic lesions in the coronary arteries. Approximately 5% of patients with acute myocardial infarction do not have atherosclerotic disease. In this case report, we present an unusual leukostatic complication in a patient with acute myeloblastic leukemia and extreme hyperleukocytosis who presented with an acute myocardial infarction that resolved after leukopheresis. Myocardial infarction as the initial presentation of acute leukemia has been reported only rarely.Keywords: leukocytosis, myocardial infarction, leukostasis
