Gender differences in antithrombotic therapy

چکیده
Evidence on the management of atherothrombotic diseases derives from clinical trials where women are usually underrepresented; however, it is well known that gender differences in the incidence and clinical presentation of cardiovascular diseases, and in the efficacy and safety of antithrombotic treatment exist. The pathophysiological mechanisms underlying these gender differences are not fully understood, and are likely multifactorial. Among patients with atrial fibrillation, women are at higher risk of stroke than men. The reasons for this elevated risk remain unclear, but may include older age, under-treatment with anticoagulant therapy, and poor anticoagulation control. Few data are available on possible gender differences regarding the efficacy and safety of direct oral anticoagulants. As concerns antiplatelet therapy, the use of aspirin for primary prevention is associated with a higher risk reduction for ischemic stroke in females and for myocardial infarction in males. In the setting of acute coronary syndromes, the female gender is associated with a significantly higher risk of bleeding. These differences could have implications for future sex-specific treatment and prevention strategies for atherothrombotic diseases. However, the inclusion of a larger number of women in randomized trials evaluating cardiovascular outcomes with the use of antithrombotic drugs is needed in order to produce stronger evidencebased recommendations. The aim of this review is to provide an overview of available data on gender differences in antithrombotic therapy, and to analyze the potential reasons accounting for them.

Impact of race and gender on antithrombotic therapy.
Large randomised trials support the use of a variety of antithrombotic drugs for treatment of atherothrombotic disease processes leading to cardiovascular disease. The heterogeneous case-mix of patients enrolled in these trials, however, hamper the attempt to generalise their findings to subgroups which are not sufficiently represented in the study population, such as women and ethnic minoritie...

متن کاملNovel Antithrombotic Drugs on the Horizon
Diseases associated with arterial thrombosis or venous thrombosis are leading causes of mortality and morbidity globally. Since the 1930s, antithrombotic therapy has been the cornerstone of medical therapy for thrombotic diseases. However, the success of antithrombotic therapy has come at the cost of one of the most dreaded iatrogenic complications—bleeding. Recently, new evidence has emerged o...

Sex-based differences in the prevalence and presentation of arterial and venous thrombosis exist, and emerging data indicate that men and women do not accrue equal benefit from antithrombotic therapy. Sex hormones alter procoagulant protein expression and the function of blood and vascular cells. Sex-based differences in platelet function have been reported, and in animal models, sex-based diff...
متن کاملThe risk of hemorrhagic complications in hospital in-patients who fall while receiving antithrombotic therapy
BACKGROUND: The use of antithrombotic agents and falls are independently associated with an increased risk of hemorrhagic injury. However, few studies have delineated the risk of fall-related hemorrhagic complications in persons who are taking antithrombotic therapy. The objective of this study was to compare the rates of fall-related hemorrhagic injury in hospital in-patients who are taking an...
