  1. Ischaemic Heart Disease-Implications of Gender Dr Kaye Birks School of Rural Health Monash University Australia Gender Competency Training for Medical Educators Seminar, April 2003

  2. Aims Describe differences between women and men • Natural history • Clinical presentations • Management • Outcome

  3. Natural History of IHD • Cause of death of approximately one third of women • Greater age dependency • Clinical onset is about 10-15 years later than for men

  4. Natural History--Risk Factorsyoung women • Family history maternal IHD • NIDDM • Smoking risk for sudden death • Isolated raised total cholesterol – less risk • Obesity risk ? explained by co-morbidity

  5. Clinical Presentations • In women angina common first presentation [54%] v. men [38%] • Recognised MI [18%] men [30%] • More atypical symptoms • Pain free MI in older diabetic women • More non Q wave infarcts

  6. Clinical Presentations • Older • Co-morbidities • Unstable angina rather than acute MI • Those with infarction less likely to have ST segment elevation

  7. Outcome differences • More likely to die • The younger the women the greater the difference when compared to male cohort • < 50 years twice as likely to die • After CABG younger women mortality 3.4% v. men 1.1% • Over 75 years no difference in mortality

  8. Outcome differences ?why • Women delay in going to hospital • Missed diagnosis on admission • Less likely to receive thrombolytic therapy • More co morbidities • Less likely to receive established treatments e.g. betablockers, aspirin • Higher death rates for men before going to hospital

  9. Outcome differences ?why • Different pathophysiology in premenopausal women • Plaque erosions in young women, plaque rupture in men and older women • Young women have less narrowing of arteries • ?hypercoaguable state or coronary spasm • Transmural MI with normal coronary angiography

  10. Management • Diagnostic testing less specific in younger women • Less likely to have coronary angiography • When performed more likely to have clinically insignificant disease • Less likely to receive primary preventive treatments

  11. Summary Differences in • natural history • presentation • management • outcome

  12. Summary • Important to highlight these differences in the undergraduate curriculum
