[Comparative evaluation of dipyridamole and dobutamine 2-dimensional echocardiography in ischemic heart disease].
Dipyridamole and dobutamine stress were performed in the same 41 angiographically controlled patients. Both tests were followed by 2 dimensional-echocardiography. The dose of dipyridamole was 0.56 mg/kg/4 min. or 0.84 mg/kg over 10 min., while the dose of dobutamine was 10-20-30-40 and 40 micrograms/kg/min. over 3 min. each step. In addition, to reach the submaximal heart rate 0.25 mg/min Atropine was also injected for 4 minutes in 13 cases. One vessel disease was found in 15 cases, and 2 vessel disease was in 2 cases. The number of coronarography negative cases was 24. The sensitivity, specificity, positive and negative predictive values for both tests were 70%, 91%, 85% and 81%, respectively. False positive results were observed in 2 cases and false negative ones were found in 5 cases, mainly at left anterior descendent stenosis. There was a good agreement between the wall motion abnormality and the anatomic localization of stenoses. Both non-invasive tests are suitable for the diagnosis of ischaemic heart disease.
