A Peculiar Case of Recurrent Coronary Artery Thrombosis.

Abstract

Coronary artery thrombosis is a phenomenon physicians have studied throughout the years. The different risk factors that play a role in the formation of an atherosclerotic plaque leading to coronary artery blockage are vast and can affect the patient significantly if not examined and diagnosed carefully. The objective of this case report is to highlight this unusual occurrence of repeated coronary artery thrombosis. A 54-year-old Caucasian female presented to the emergency department with a one-day history of sharp chest pain in the substernal area that radiated between her shoulder blades and left arm. Despite being on dual antiplatelet therapy, an electrocardiogram (ECG) showed an inferior ST-elevation myocardial infarction (STEMI). Her medical history was extensive with factor V Leiden deficiency, hyperhomocysteinemia, recurrent deep vein thrombosis (DVT), and a family history of myocardial infarction. The patient was taken to the cardiac catheterization lab based on these characteristics. The patient was diagnosed with a 100% thrombosis in the distal right coronary artery (RCA), which was stented nine months before this current presentation. The patient had been compliant with all her medications from her previous stent placement. A new drug-eluting stent (DES) was inserted, and the patient was placed on prasugrel and apixaban. This was a very interesting topic for a case report due to the time frame of repeat thrombosis in a coronary artery with a DES and the patient’s underlying hypercoagulable state. There are few cases of same vessel restenosis post-DES placement. Our case highlights the need for further research into the prevalence of genetic risk factors in coronary artery thrombosis and the need to investigate the efficacy of different anticoagulation therapies in patients with factor V Leiden thrombophilia.
