Overview

Explains heparin action via antithrombin kinetics alone in plasma; leaves open independent cofactors in human or diseased states.

Structured PICO

Population
Plasma samples and literature data on antithrombin and heparin characteristics
I
Intervention
Addition of heparin or saline dilution to plasma
C
Comparator
Isolated heparin cofactor preparation or normal plasma
O
Outcome
Rate of thrombin inactivation and antithrombin capacitysurrogate

The action of heparin in plasma can be quantitatively accounted for by its effects on antithrombin, suggesting an independent heparin cofactor does not exist in normal plasma.
