| Résumé : | The interpretation of exercise ECG is difficult in women for two reasons: from a methodological point of view, a too low maximal power is often reached, the test being interrupted owing the muscular fatigue or lack of motivation; from a pathophysiological point of view, a rather high percentage of false positive results is observed in women, especially when resting ECG is abnormal, as appears from comparisons with coronary angiograms. The role of estrogens, abnormal oxyhaemoglobin dissociation curves, distal coronary lesions, hormonal contraceptives, vasoregulatory asthenia and Bayes's theorem have been put forward. Practically, a diagnosis of coronary insufficiency should be avoided in women when based only on the exercise test; an isolated positivity of the latter usually envolves a good long-term prognosis. However, exercise testing still remains of much interest in women, the probability of coronary disease being low when it is negative while few major lesions of large vessels justifying aortocoronary bypass have a negative test. |
