The diagnostic value of the dipyridamole echocardiography test was investigated in 46 patients who underwent coronary angiography due to suspected ischaemic heart disease. Twenty-two of 46 patients were found to have a narrowing of at least 70% one vessel. Twenty-four hour ECG monitoring was also performed on 19 patients on the day of the dipyridamole test. The sensitivity and specificity of the two-dimensional echocardiography test (new wall motion abnormality) were 72.7% and 62.5%. The ECG (V2-5-9) had a low sensitivity during the test (43.8%). Good agreement was found between the localization of the wall motion abnormalities and the site of anatomic narrowing in the ischaemic group. No significant ventricular arrhythmias were detected, and the sensitivity and specificity of ST-T changes were found to be 62.5% and 54.6% by means of Holter monitoring. The dipyridamole echocardiography test proved to be a suitable noninvasive method for the diagnosis of ischaemic heart disease and for the selection of patients for coronary angiography.
