Insights
This case report details recurrent coronary artery thrombosis in a patient with Factor V Leiden deficiency despite dual antiplatelet therapy and a drug-eluting stent. It underscores the need for research into genetic risk factors and anticoagulation efficacy.
Area of Science:
- Cardiology
- Genetics
- Thrombosis
Background:
- Coronary artery thrombosis is a significant clinical concern, influenced by numerous risk factors including atherosclerosis.
- Understanding plaque formation and blockage is crucial for patient diagnosis and management.
Observation:
- A 54-year-old female presented with acute chest pain and ST-elevation myocardial infarction (STEMI) despite dual antiplatelet therapy.
- Her history included Factor V Leiden deficiency, hyperhomocysteinemia, and recurrent deep vein thrombosis (DVT).
- She experienced repeat thrombosis in a stented right coronary artery (RCA) within nine months, despite medication compliance.
Findings:
- The patient was diagnosed with 100% thrombosis in the distal RCA, nine months after initial stenting.
- A new drug-eluting stent (DES) was implanted, and anticoagulation with prasugrel and apixaban was initiated.
- This case highlights rare same-vessel restenosis post-DES placement in a patient with a hypercoagulable state.
Implications:
- This case emphasizes the need for further research into the prevalence of genetic risk factors in coronary artery thrombosis.
- Investigating the efficacy of various anticoagulation therapies in patients with Factor V Leiden thrombophilia is warranted.
- Further studies are needed to understand repeat thrombosis in stented arteries, especially in patients with inherited thrombophilia.
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.
