Inherited hypercoagulable states: questions and controversies

Area of Science:

• Hematology
• Genetics

Background:

• Inherited hypercoagulable states, such as deficiencies in protein C, protein S, and antithrombin III, are significant contributors to recurrent thromboembolic events, accounting for 15-20% of cases.
• These genetic disorders share common risk factors that inform laboratory screening protocols.

Purpose of the Study:

• To outline the risk profile associated with inherited hypercoagulable states.
• To guide the appropriate use of laboratory screening for these conditions.
• To discuss the management of anticoagulation in patients with inherited hypercoagulable states, considering personal and family history.

Main Methods:

• Review of existing literature on inherited thrombophilia.
• Analysis of risk factors and screening guidelines.
• Discussion of anticoagulant therapy strategies.

Main Results:

• Identified a common risk profile for inherited hypercoagulable states.
• Established the utility of laboratory screening based on risk factors.
• Highlighted the variable need for anticoagulants based on thrombosis history.

Conclusions:

• Inherited deficiencies of protein C, S, and antithrombin III are key causes of recurrent thrombosis.
• Risk stratification is essential for guiding screening and anticoagulant management.
• Anticoagulant therapy requires individualized consideration, particularly in perioperative and pregnancy settings.
