Insights
This case study shows that acute coronary syndrome in hemophilia A patients can be safely managed with standard invasive coronary interventions and post-procedure care, including usual coagulation factor doses.
Area of Science:
- Cardiology
- Hematology
Background:
- Hemophilia A patients present unique challenges for managing cardiovascular diseases due to bleeding risks.
- Acute coronary syndrome (ACS) requires timely and effective intervention, which may be complicated by bleeding disorders.
Observation:
- A 55-year-old male with hemophilia A experienced recurrent chest pain after a coagulation factor overdose.
- Coronary imaging revealed moderate stenosis, progressing to severe thrombotic occlusion requiring stent placement.
- The patient received dual antiplatelet therapy followed by single antiplatelet therapy under conventional hemophilia management.
Findings:
- Successful percutaneous coronary intervention (PCI) with a bare metal stent was performed.
- The patient remained event-free for 5 years on single antiplatelet therapy (clopidogrel) with standard hemophilia care.
- No major bleeding complications were reported during the management of ACS.
Implications:
- Invasive coronary interventions and post-procedural management for ACS are feasible in hemophilia A patients using standard protocols.
- Maintaining usual coagulation factor doses alongside antiplatelet therapy appears safe and effective.
- This case supports the integration of cardiovascular care within hemophilia management protocols.
Abstract:
A 55-year-old male with hemophilia A came to the outpatient clinic with chest pain for several days after overdose injection of coagulation factor. He was a heavy smoker and a chronic alcoholic. An electrocardiogram (ECG) showed no specific change. A coronary computed tomography showed moderate stenosis with soft plaque at the distal segment of right coronary artery. His pain was improved with antianginal and reflux medications. Twenty days later, he ran to the emergency room complaining of squeezing chest pain. ECG showed mild ST segment elevation in inferior territories. Invasive coronary angiography via right radial artery revealed severe thrombotic occlusion at the same lesion. A bare metal stent was deployed and dual antiplatelet therapy including aspirin and clopidogrel had been maintained for 6 months under the conventional hemophilia management. The patient did not develop any coronary events just with single clopidogrel therapy for 5 years until he passed away from pancreatic cancer. Our case implicates that the invasive coronary intervention and post-procedural management could be safely performed with conventional standards of care while maintaining the usual dose of coagulation factors in a hemophilia patient with acute coronary syndrome.

The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
