Myocardial infarction and factor VIII elevation in a 36-year-old man

We report a 36-year-old man who had a myocardial infarction despite lacking traditional cardiac risk factors. He developed end-stage heart failure and renal insufficiency necessitating a HeartMate II left ventricular assist device (LVAD). While on the transplant list, he experienced two episodes of LVAD thrombosis 6 months apart, prompting device exchange and escalation of anticoagulation therapy. He eventually underwent a successful heart-kidney transplant before suffering an extensive left lower extremity deep vein thrombosis 6 weeks later. A thrombophilia workup revealed elevated factor VIII activity of 319% (normal range, 50%-150%). He was placed on indefinite anticoagulation with apixaban with no further thrombotic episode in 18 months of follow-up to date.PMID:34970049 | PMC:PMC8682839 | DOI:10.1080/08998280.2021.1973285
