[How to and why evaluate the ischemic risk after myocardial infarction?].
After uncomplicated myocardial infarction, clinical and ergometric data before hospital discharge allow identification of patients at high risk of further cardiac events. These relate to the necrosed myocardium (left ventricular dysfunction, sometimes latent, and arrhythmia risk), and also to the jeopardized myocardium: the moderate sensitivity and specificity of classical exercise stress testing for the detection of this often silent ischaemia are much improved by stress radionuclide and echocardiographic techniques (exercise, dipyridamole, dobutamine. . .), the large scale indications of which remain to be validated.
