Outcome Measures

Primary Outcomes (2)

  • Level of Urinary Thromboxane (UTXB2) in pg/mg Creatinine

    Urinary thromboxane (pg/mg creatinine) will be measured in premenopausal and postmenopausal women at baseline and then after taking on aspirin for 7 days.

    Baseline

  • The Change in the Level of UTXB2 in pg/mg Creatinine: Estrogen and Progesterone

    Measurement of urinary thromboxane (pg/mg creatinine) in relation to estrogen to progesterone level in premenopausal women on aspirin for 7 days.

    baseline to 7 days

Secondary Outcomes (2)

  • Level of UTXB2 in pg/mg Creatinine

    baseline

  • Relative Change of UTXB2 in pg/mg Creatinine in Response to Aspirin
