Background: the onset of angina and/or ST segment displacement during exercise testing (ET) is useful in the diagnosis of ischemic heart disease (IHD). Other changes in the electrocardiogram also may be of diagnostic value. One of them is the QRS or Athens Score (SDA) based in changes in the amplitude of the QRS complex recorded at rest and immediately post-stress. The purpose of this study is to determine the validity of the SDA in the diagnosis of IHD, secondarily, to evaluate SDA results according the functional class (CF) and the increment in the double product (DP) during the ET. Material and method: we conducted a retrospective study in 75 patients referred to perform myocardial perfusion imaging (EPM) with ET. The diagnosis of ischemia was done in 25 patients with moderate to severe reversible defects. Results: the SDA mean value expressed in mm (±SD) was -0,16 ± 4,39 for EPM (+) and 1,88 ± 4,3 for EPM (-), the difference was non-significant (p=0.062). However, there were significant differences in patients with CF I (> 7 MET) or a DP >2,5 times the baseline. In the first, the SDA was -3,73 ± 6,83 in EPM (+) and 5,2 ± 4,34 in the EPM (-) (p< 0,02). In those with DP increased >2.5 times, the SDA was -1,57 ± 6,99 in the EPM (+) and 3,64 ± 4,72 EPM (-) (p<0,03). Conclusion: the SDA have diagnostic utility for predicting moderate to severe ischemia in the EPM in those patients with CF I or an increment of the DP >2,5 in the ET.
