[Significance of 2-dimensional echocardiography for the diagnosis of dipyridamole-induced myocardial ischemia in patients with coronary heart disease].

In 24 patients with coronary heart disease (group 1) and in 16 control patients (group 2) dipyridamole test was performed in combination with two-dimensional echocardiography. The studies were aimed at the comparison of sensitivity, specificity and predictive values calculated during analysis of segmental contractility of the left ventricular wall and LVEDVI, LVESVI, SVI, CI and EF in relation to ecg examination. During analysis of changes in ST segment, dipyridamole test sensitivity was 0.37, specificity--0.94, predictive confirmatory value--0.90, and predictive excluding value--0.50. During analysis of LVEDVI, SVI and CI diagnostic value of the dipyridamole test did not change (p greater than 0.05). During analysis of LVESVI and EF dipyridamole test sensitivity increased to 0.75 and 0.83, respectively (p less than 0.05). Also during analysis of segmental contractility of the left ventricular wall sensitivity of the test increased to 0.75 (p less than 0.01), while its specificity and predictive value did not change (p greater than 0.05). Two-dimensional echocardiography augments diagnostic value of the dipyridamole test.
