Abstract

Antiplatelet therapy is a cornerstone of secondary prevention of cardiovascular diseases (CVDs). However, current guidelines are based on data derived primarily from men, as women are generally underrepresented in trials. Consequently, there are insufficient and inconsistent data on the effect of antiplatelet drugs in women. Sex differences were reported in platelet reactivity, patient management, and clinical outcomes after treatment with aspirin, P2Y12 inhibitor, or dual antiplatelet therapy. To evaluate whether sex-specific antiplatelet therapy is needed, in this review we discuss (i) how sex affects platelet biology and response to antiplatelet agents, (ii) how sex and gender differences translate into clinical challenges and (iii) how the cardiological care in women might be improved. Finally, we highlight the challenges faced in clinical practice regarding the different needs and characteristics of female and male patients with CVD and address issues requiring further investigation.
