- W4380715103 abstract "Introduction: Acute coronary syndrome (ACS) occurring in the presence of a bleeding diathesis can make clinical decision-making difficult. We present a case of a non-ST elevation MI in the presence of an acquired factor VIII deficiency with an inhibitor present. Case: A 66-year-old male with a medical history significant for coronary artery disease and COPD presented with a 4-day history of persistent, profuse bleeding after attaining a laceration on his arm. Shortly after admission, he reported pressure-like chest pain relieved by sublingual nitroglycerin. His 5th generation troponin level was 61 ng/L on presentation and peaked at 600 ng/L 36 hours later. The EKG revealed ST depressions in leads V3 and V4 and T-wave flattening in leads V5 and V6. Transthoracic echocardiography revealed preserved ejection fraction but could not exclude wall motion abnormalities due to poor windows. Hematology was consulted due to uncontrolled bleeding, and the patient was diagnosed with acquired factor VIII deficiency with an inhibitor present. Low-dose heparin infusion was initiated. He was taken for a diagnostic left heart catheterization, which revealed left main with moderate obstruction, left anterior descending (LAD) with 70% proximal stenosis, and a small diagonal branch with 90% stenosis. The patient had been previously offered evaluation for coronary artery bypass graft(CABG) surgery but declined. CABG work up was ultimately deferred in favor of percutaneous coronary intervention based on literature review extrapolated from hemophiliac patients. The patient’s hematologic care is ongoing with recombinant antihemophilic factor, porcine sequence, prednisone, cyclophosphamide, and rituximab administration. Discussion: Choosing the type of coronary revascularization in coagulopathic patients poses a significant challenge. To avoid complications, a multidisciplinary approach to short- and long-term anticoagulation management is necessary. In this case we decided to use existing data that is based on hemophilia patients in the past with myocardial infarction where dual antiplatelet therapy is limited to 1 month with factor 8 activity maintained above 30%. Then transition to aspirin alone for maintenance with factor 8 levels maintained above 10%." @default.
