- W2364387431 abstract "Objective To investigate the prognostic value of hemodynamic alterations during dobutamine stress echocardiography(DSE) in patients with coronary artery disease(CAD). Methods 117 persons were studied by DSE and divided into 2 groups: control group(group A,n=32) and CAD group (group B,n=85); the prognostic value of hemodynamic alterations was assessed according to the findings collected during follow-up. Results Successful follow up of 108 cases revealed 33 cardiac events happened among the 80 cases of group B,including 14 hard cardiac events and 19 soft cardiac events; the mean of risk factors was 3.3±1.4. No cardiac events happened in the 28 persons of group A. The hemodynamic variables in the patients with cardiac events were significantly different from those without cardiac events (P0.01). Significant difference existed in the cumulative survivalrate between the group of patients with normal SBP/ESVI ratio and that of patients with SBP/ESVI subnormal(P0.01). Conclusion The factors inducing myocardial ischemia in patients with CAD, such as the increase of HR, SBP, RPP, SBP/ESVI, wall stress and mild lowering of TVRI, especially the subnormal value of SBP/ESVI following maximal dobutamine stress are of prognostic value predicting possible cardiac events in the longer course of follow-up." @default.
