Purpose:
To study the safety and feasibility of dobutamine-atropine stress echocardiography (DASE) in patients with known or suspected coronary artery disease.
Methods:
There were 3,000 DASE that were studied in a prospective fashion. All symptoms and side effects were stored in a data base format.
Results:
Major test-related complications observed included one case of myocardial infarction, four cases of sustained ventricular tachycardia and five cases of atropine intoxication. There was no death or ventricular fibrillation as a direct or indirect consequence of the test. The infusion protocol allowed to us to examine patients using beta blockers, and led to 95% feasibility.
Conclusion:
DASE is a safe and feasible method for the study of patients with suspected or known coronary artery disease.
