[Comparison of usefulness of dobutamine-atropine and dobutamine-adenosine stress echocardiography in detection of coronary artery disease].
Stress echocardiography is valuable, non-invasive method useful for detection of coronary artery disease. In stress echocardiography myocardial ischemia is most commonly induced by exercise or pharmacological agents like dobutamine, dypiridamole, arbutamine or adenosine. The aim of the study was to compare usefulness of dobutamine-atropine stress echocardiography (DATR) with dobutamine-adenosine stress echocardiography (DADE) in detection of coronary artery disease. Studies were carried out in 23 patients, 11 women and 12 men, with suspected coronary artery disease. Both DATR and DADE were performed in all patients. In DATR left ventricular segmental contractility was estimating during intravenous infusion of dobutamine in increasing doses from 5 to 40 microg/kg/min and after intravenous administration of 1 mg of atropine. In DADE regional left ventricular systolic function was analyzed during intravenous infusion of dobutamine in increasing doses from 5 to 40 microg/kg/min and adenosine in dose of 0.14 mg/kg/min. The sensitivity of DATR in detection of coronary artery disease was 87% and specificity was 85%, whereas DADE 87% and 100% respectively. The sensitivity of DATR and DADE in subgroups of patients with one-vessel and multivessel disease was equal: 83% and 90% respectively. There were no significant differences between DADE and DATR in respect of sensitivity and specificity in detection of coronary artery disease. The results of this study suggest that dobutamine-adenosine stress echocardiography is highly sensitive and specific diagnostic test for detection both one-vessel and multivessel coronary artery disease. Moreover, there is no statistically important difference between dobutamine-adenosine stress echocardiography and dobutamine-atropine echocardiography in respect of sensitivity and specificity in detection of coronary artery disease.
