    Abstract:
    There are few studies on the behavior of the diastolic blood pressure during the stress test. The purpose of this report is to present a simple, noninvasive technique of measuring the mean diastolic arterial blood pressure at rest, during maximal exercise testing and in the first minute of recovery (X delta DAP). We studied 132 patients with exercise testing (E/T) and coronariography (C). Of these, 116 had coronary artery disease and 16 did not. The following data were analyzed: Age (A) X delta DAP, X2, p value, sensitivity, specificity, positive predictive value (PV+), and negative predictive value (PV-). As we analyzed our patients with coronary arterial disease, we found that in 75% of the cases, the X delta DAP increased more than 15 mmHg, immediately after maximal effort, and 86% of these cases had poor myocardial contratility by angiocardiogram. We conclude that the increase of X delta DAP has a significant value in a ischemic heart disease.
