The autonomic nervous system is of importance in the natural history and treatment of a number of pathophysiological states involving the cardiovascular system. These include hypertension and diseases of the vasculature as well as myocardial ischaemia and cardiac arrhythmias. Gender differences in the incidence and clinical course of a range of cardiovascular states are also well recognised. Both short and long term prognosis after myocardial infarction are worse for women than men [1–4], whereas women with non-ischaemic cardiomyopathy have improved survival [5,6]. In addition to the well known difference in age of presentation of coronary heart disease, women are more likely to suffer from Raynaud's phenomenon, and to experience presyncopal or syncopal episodes. An appreciation of gender differences in the structure and function of the autonomic nervous system is therefore important to a full understanding of a number of common and important clinical presentations [7].
