Although the female gender is generally less represented in cardiovascular studies, observational and randomized investigations suggest that-compared with men-women may obtain different benefits from antiplatelet therapy. Multiple factors, including hormonal mechanisms and differences in platelet biology, might contribute to such apparent gender peculiarities. The thrombotic and bleeding risks, as well as outcomes after a cardiovascular event, appear to differ between genders, partly in relation to differences in age, comorbidities and body size. Equally, the benefits of antiplatelet therapy may differ in women compared with men in different vascular beds, during primary or secondary prevention and according to the type of an antiplatelet agent used. This document is an attempt to bring together current evidence, clinical practices and gaps of knowledge on gender-specific platelet function and antiplatelet therapy. On the basis of the available data, we provide suggestions on current indications of antiplatelet therapy for cardiovascular prevention in women with different clinical features; no strong recommendation may be given because the available data derive from observational studies or post hoc/subgroup analyses of randomized studies without systematic adjustments for baseline risk profiles.

The prevalence and incidence of diabetes is similar in the two sexes but the long-term impact of diabetes on vascular and non-vascular complications is more gender specific. Men, in comparison with women, seem to be at higher risk for micro-vascular complications, such as severe retinopathy and nephropathy. On the other hand, the impact of diabetes on the risk of major cardiovascular events is different in women in comparison with men. Both type 1 and type 2 diabetes are associated with a significant increase in the incidence of bone fractures. Although this phenomenon is present in both sexes, its impact is greater in women, due to the higher baseline incidence of fractures. Diabetes negatively affects mood, leading to an increased risk of depressive disorders, due to the burden and side effects of therapy, together with the fear of complications. This phenomenon can be more evident in women, who are at greater risk of depressive disorders. Non-pharmacological treatments (i.e. diet and exercise), which are the backbone of therapy for type 2 diabetes, do not differ across genders. On the other hand, some drugs could have diverse profiles of action in women and in men. In relation to diabetes, the sex-related difference in platelet activity and platelet inhibitory response to anti-aggregating therapy, reported in the general population, was observed also in diabetic women.
