[Dobutamine stress echocardiography: a new possibility in the diagnosis of coronary disease]. / Dobutamin stressz echocardiographia: új lehetöség a koszorúér-szívbetegség diagnosztikájában.

Authors performed dobutamin stress test since 1987 and combined their examinations with 2D-echocardiography in case of suspected coronary artery disease since October 1991. In this study they report on their experiences obtained in the course of the first 32 examinations. The results of the dobutamine stress echocardiography were analysed on the basis of coronarography which was performed in every patient. According to their observations dobutamine stress echocardiography has very good sensitivity and specificity and it is practically a harmless method, but as it requires instruments, assistants, time and work. Authors recommend the method first of all as a complementary to the physical loading method as well as alternative loading examination.

In the diagnostics of the coronary artery disease different exercise tests are well-known to be important. On the basis of the increasing number of publications of the eighties the authors examined the applicability of dobutamin stress test in 89 patients, whose anamnesis did not contain any justification of coronary artery disease. All patients were examined by coronarography. The authors compared the results of different tests with the results of coronarography. They found the sensitivity of dobutamin stress test significantly higher and its specificity--although not significantly--lower, than the dynamic treadmill tests, however the combination of the two methods resulted in very good sensitivity and acceptable specificity.
