There is one clinical trial.
To examine in postmenopausal women the potential interactions of hormone replacement therapy with other blood clotting factors on the risk of cardiovascular diseases such as heart attack or stroke.
The main variants of interest are: (la) factor XIIIA Val34Leu; (ib) platelet glycoprotein (PGP) Jib Ile843Ser; (ic) PGP IIIa Leu33Pro; and (id) PGP Ia C807T. --- Val34Leu --- --- Ile843Ser --- --- Leu33Pro --- --- C807T ---
The secondary aims include the assessment of other drug-gene, risk-factor-gene or gene-gene interactions on risk: (2a) the interaction between PGP IIb Ser843, PGP lila Leu33Pro and PGP Ia C807T and traditional cardiovascular risk factors such as smoking and obesity on the risk of MI and stroke; (2b) the interaction between three coagulation factor XIII polymorphisms and PAl-1 4G/5G on the risk of stroke in women; and (2c) the interaction between aspirin use and glycoprotein IIIa Leu33Pro on the risk of MI and stroke. --- Leu33Pro --- --- C807T ---
