- Investigate the cyclic variation in clot lysis time in women with HMB in comparison to controls.
Achtergrond van het onderzoek
Heavy menstrual bleeding (HMB) is known to be associated with gynaecological abnormalities and can also be associated with a wide range of haemostatic disorders. There is also evidence that fibrinolysis in the endometrium plays an important role in menstruation. The role of systemic fibrinolysis in women with heavy menstrual bleeding was studied and showed no increased systemic fibrinolysis in women with heavy menstrual bleeding. Certain fibrinolytic parameters were even higher in patients with heavy menstrual bleeding. An explanation why we found no increased systemic fibrinolysis could be the moment of testing in the menstrual cycle. Probably there is cyclic variation in menstruating women with menorrhagia. This hypothesis needs to be tested by measuring fibrinolytic parameters during the menstrual cycle in women with HMB and controls with normal menstrual bleeding.
