The leading cause of death in the perioperative period after noncardiac surgery is a cardiac event. As the number of lumbar surgeries performed in patients older than 65 years of age continues to increase, this patient population with neurogenic claudications is an at risk group for a cardiac event because of their age and associated cardiac risk factors. The authors attempted to document by means of cardiac chemical stress testing, the prevalence of silent ischemic cardiac disease in patients with neurogenic claudication who were candidates for elective lumbar surgery. Eleven of 140 patients (8%) had induced cardiac wall abnormalities on stress testing, indicating myocardial ischemia. The only risk factors associated with cardiac ischemia were smoking and history of heart disease. It is recommended that dobutamine stress echocardiography be performed in patients undergoing elective spinal surgery for symptomatic spinal stenosis if they have a history of previous heart disease, smoking, or both.
