[The value of 2-dimensional echocardiography in conjunction with various exercise tests for diagnosis of myocardial ischemia].

In 16 persons of the control group (group I) and in 27 patients with coronary heart disease (group II) value of two-dimensional echocardiography was determined combined with exercise, transoesophageal left atrial pacing, dipyridamole and cold pressor tests in detecting myocardial ischaemia. Changes of ST-segment in the ECG, left ventricular ejection fraction and wall motion in the 11 segments were studied during the tests. Sensitivity, specificity and predictive value confirming and excluding ischaemic heart disease of the analyzed parameters were determined. The sensitivity and the specificity of exercise, left atrial pacing, dipyridamole and cold pressor tests during the analysis of ST-segment were 70%, 81%, 37%, 4% and 62%, 67%, 94%, 100%, respectively. Two-dimensional echocardiography analysis did not increase the diagnostic value of the exercise and left atrial pacing tests, whereas the diagnostic value of dipyridamole and cold pressor tests were increased.
