Differential Diagnosis for Arterial Hypercoagulability Causing Infarction

Single Most Likely Diagnosis

  • Atherosclerosis: This is the most common cause of arterial hypercoagulability leading to infarction, particularly in the context of myocardial infarction (heart attack) and stroke. Atherosclerosis involves the buildup of plaques in the arterial walls, which can rupture and lead to thrombus formation, causing an infarct.

Other Likely Diagnoses

  • Antiphospholipid Syndrome (APS): An autoimmune disorder that increases the risk of blood clots, including arterial thrombosis. It can cause infarctions in various organs, including the brain, heart, and kidneys.
  • Hyperhomocysteinemia: Elevated levels of homocysteine in the blood, which can damage the lining of arteries and promote blood clot formation, leading to infarction.
  • Factor V Leiden: A genetic mutation that increases the risk of developing blood clots due to an alteration in one of the clotting factors, potentially leading to arterial thrombosis and infarction.

Do Not Miss Diagnoses

  • Disseminated Intravascular Coagulation (DIC): A condition characterized by the widespread formation of blood clots in small blood vessels throughout the body, which can lead to organ failure and is often fatal if not promptly treated.
  • Thrombotic Thrombocytopenic Purpura (TTP): A rare blood disorder characterized by the formation of blood clots in small blood vessels throughout the body, which can lead to microangiopathic hemolytic anemia and is life-threatening if not treated promptly.
  • Heparin-Induced Thrombocytopenia (HIT): A complication of heparin therapy that can paradoxically increase the risk of blood clots, leading to severe thrombotic events, including infarctions.

Rare Diagnoses

  • Prothrombin Gene Mutation (G20210A): A genetic mutation that increases the production of prothrombin, a clotting factor, thereby increasing the risk of blood clots.
  • Protein C or S Deficiency: Rare genetic disorders that affect the production of proteins necessary for regulating blood clotting, leading to an increased risk of thrombosis.
  • Malignancy-Associated Thrombosis: Certain types of cancer can increase the risk of blood clots, including arterial thrombosis, due to the production of pro-coagulant substances by tumor cells.
