Menstrual bleeding-specific quality of life in women on antiplatelet therapy

Abstract

Background

Antiplatelet therapy may affect menstrual blood loss in women of reproductive age.

Objectives

To determine menstrual bleeding and related quality of life (QoL) in women on antiplatelet therapy.

Methods

We performed a cross-sectional study at a tertiary care center in the Netherlands, including women on antiplatelet therapy with an active menstrual cycle and a control group of reproductive-aged women who did not use antiplatelets. Participants completed an online questionnaire containing 2 validated instruments: (1) the Menstrual Bleeding Questionnaire (MBQ) to measure menstrual bleeding-specific QoL, and (2) the Pictorial Blood Loss Assessment Chart (PBAC). Scaled MBQ scores range from 0 to 100, with higher scores indicating worse QoL. A PBAC score of 100 is generally considered indicative of heavy menstrual bleeding.

Results

In total, 38 women prescribed antiplatelet drugs (median age, 44 years [IQR, 40-48]) and 100 control women (median age, 35 years [IQR, 27-43]) completed the study questionnaire. Most common indication for antiplatelet therapy was stroke/transient ischemic attack (26%). Acetylsalicylic acid/carbasalate calcium (50%) and clopidogrel (37%) were most frequently used. Mean (SD) scaled MBQ scores were 18.9 (11.2) among antiplatelet drug users and 22.4 (10.9) in control women (adjusted mean difference, −3.28 [95% CI, −7.90, 1.35]). Median PBAC scores were 101.5 (IQR, 50.5-207) and 96.0 (IQR, 73.0-174.8; adjusted mean ratio, 0.784 [95% CI, 0.521, 1.18]), respectively. A PBAC score >100 was reported in 37% and 36% of the antiplatelet and control groups, respectively.

Conclusion

Menstrual bleeding-specific QoL was comparable between women on antiplatelet therapy and controls, although controls experienced a high burden of menstrual bleeding-related complaints. Menstrual blood loss did not seem to be increased.
