Exercise ECG : diagnosis • Exerctional symptoms of low predictable value • Shorter exercise duration • Lower CAD prevalence • Reported high rate of false positives • Heart rate recovery • Functional capacity • Integrative test scores
Stress echocardiography in womenDiagnosis • No ionization radiation • Systolic and diastolic Ventricular dysfunction • Valvular disease • Extent of infarction and stress induced ischemia • Minimal added cost • More cost effective than exercise ECG • Exercise test or pharmacological test • Reduced image quality (obese,smokers) NO SEX EFFECT
RISK ASSESSMENT 5yr survival 4234 womenexercise and dobutamine stress Shaw EUR HEART J 2005
CARDIAC RADIONUCLIDE IMAGING • Perfusion defect • Global and regional left ventricular function • Left ventricular volumes • Lung uptake of 201 Tl • Exercise test or pharmacological test

Role of non invasive testing in the clinical evaluation of women with suspected CAD Asymptomatic women • Low risk in premenopausal women except • High risk : diabetes, periferal arterial disease, chronic kidney disease • Framingham risk score intermediate (controversial recommendation)
