What happens in Hypercoagulability?

A hypercoagulable state, also known as thrombophilia, is an increased tendency to develop blood clots (thrombosis) due to the presence of one or more predisposing factors, which can either be inherited or acquired.

What causes hypercoagulable state?

What causes hypercoagulable states? Hypercoagulable states are usually genetic (inherited) or acquired conditions. The genetic form of this disorder means a person is born with the tendency to form blood clots.

Is a warfarin overdose lethal?

What is warfarin-induced coagulopathy?

Warfarin-induced coagulopathy Warfarin and related VKAs, whether ingested accidentally, factitiously, or as an overdose of oral anticoagulant therapy, lead to a deficiency of vitamin K–dependent proteins, prolongation of the prothrombin time and partial thromboplastin time, and clinical bleeding manifestations.

What is hypercoagulable state?

Hypercoagulability describes the pathologic state of exaggerated coagulation or coagulation in the absence of bleeding. Arterial thrombosis, such as in myocardial infarction and stroke, is different from venous thromboses, such as deep venous thrombosis (DVT) and pulmonary embolism (PE).

What causes a hypercoagulable state?
