Objective To evaluate the cardiovascular risk for non-cardiac thoracic surgery （NCTS） in elderly patients with dobutamine stress echocardiography and to decrease surgical risk for NCTS in the geriatrics. Methods Dobutamine stress echocardiography was used for cardiovascular evaluation in 32 NCTS candidates aged over 65 years. Patients with positive echocardiography underwent coronary angiography. Postoperative course and all complications were carefully recorded for the study. Results No serious cardiovascular events occurred during the test except for atrial or ventricular premature contracts in 5 cases. In 2 patients （6.7%,2/30） dobutamine test was positive and coronary artery occlusion was proved by further angiography. Thoracotomy was performed in 28 cases, including 2 cases with dubious result at dobutamine test. Cardiopulmonary complications occurred in 13 patients （46.4%,13/28） after surgery. Supraventricular tachyarrhythmia was the most common complication, occurred in 8 patients （28.6%,8/28）. One of the 2 patients with dubious result at dobutamine test developed definitive angina in the 5th postoperative day. The negative predictive value of dobutamine test was 100%. Conclusion Dobutamine stress echocardiography is a safe and effective method to evaluate major cardiovascular risk of NCTS in the geriatrics. But it is not predictive of tachyarrhythmia after surgery.
