7 Benefits of Exercise Coronary artery disease leading cause of death in women in developed countries Kills more women than cancer, accidents and diabetes combined Prevention of diabetes, hypertension, and hyperlipidaemia, obesity Improves endothelial function, reduces peripheral resistance, lowers LDL, increase HDL, increase insulin responsiveness, improves glucose tolerance

9 How Much Exercise? minutes of moderate physical activity every day Women who exercised > 5 hours per week 40% reduction in RR of a cardiac event Benefits more related to duration than intensity of exercise Psychological and physiological benefits

10 Cardiovascular Response to Exercise in Women Lower stroke volume and smaller increase in SV from rest to exercise Smaller LV volume and mass Lower V0 2 max, but HR max no different Training effect similar in males and females Gradual age related decline, but not related to menopause

11 Cardiac Remodelling Mild left ventricular and left atrial dilatation Wall thickness > 12 mm very rare ( cf males) Increase in LV mass uncommon Age, body size, resting HR and type of sport effect LV size Other mechanisms- lower BP with exercise, lower androgenic hormones, genetic factors

12 Pellicia A et al. 2007

13 24 year old Keen runner More SOB with exercise last 6 months Intermittent palpitations, worse with exercise, associated with light headedness No relevant past or family history

38 FloJo m seconds

39 Eating disorder, oligomennorrhea, decreased bone density

40 Take Home Messages Female participation in sport increasing and to be encouraged History and examination. More atypical symptoms in females ECG Resting and exercise stress echocardiography Different response to exercise than males

41 Take Home Messages Exercise testing in those at intermediate or greater risk or if any cardiac symptoms Avoid high intensity exercise in those with significant CAD, impaired ejection fraction, dysrhythmia, hypotension or uncontrolled hypertension Adverse events more common in those who exercise irregularly or at start of a programme Appropriate screening important
