title: [Multiparameter analysis of the ergometric test. Significance of the failure of systolic blood pressure to decrease during recovery phase as an index of coronary disease].
abstract: Ergometric tests were performed in 27 patients who had previously undergone coronarography following instrumental findings and/or symptoms which seemed highly indicative of ischemic cardiopathy. The aim of the study was to assess the diagnostic importance of the failure of systolic blood pressure to decrease during the third minute of the recovery phase of the test as an index of coronary disease. In particular, as reported by other studies, the ratio between systolic blood pressure at the third minute of recovery and maximum systolic blood pressure during the test was also assessed values above 0.7 were considered pathological. Sixteen out the 27 patients examined showed lesions which were hemodynamically significant, whereas 11 patients were free of lesions and 9 had previous myocardial necrosis. The level of the above ratio in subjects without significant coronary lesions was 0.66 +/- 0.05, whereas it was 0.85 +/- 0.04 (p less than 0.01) in patients with coronary disease. Sensitivity, specificity, and positive and negative prognostic values were respectively 91.6%, 62%, 64.7% and 90.9%. In patients with lesions to the three main arteries both the sensitivity and the specificity were 100%. In the same patients, the ST criteria were 85.7%, 50%, 81.8% and 74.3%.
