A Comparison of Two-Dimen Echocard vs Carotid Duplex Scanning in Older Pts with Cerebral Ischemia Arch Int Med 152:2089-2093, Voyce,S.J.,et al, 1992 See this aricle in Pubmed Article Abstract Twenty-five of 68 patients had Q-wave myocardial infarction by electrocardiography;nine(36%)of these 25 had left ventricular mural thrombi demonstrated by 2D echocardiography.In contrast,none of 43 patients without Q-wave myocardial infarction had clinically unsuspected findings diagnosed by 2D echocardiography.Duplex scanning;however, identified significant,abnormal findings in the carotid artery ipsilateral to the involved cerebral hemisphere in 23 patients(34%).Thus,in older patients in sinus rhythm who suffer a cerebral ischemic event,carotid duplex scanning has a higher diagnostic yield than 2D echocardiography and appears to be a more cost-effective initial test.Our data suggest that in patients with carotid distribution cerebral ischemic events and no obvious cardiac source for emboli by history and physical examination,2D echocardiography should be limited to those withy evidence of Q-wave myocardial infarction by electrocardiography;such management should optimize diagnostic yield and cost effectiveness.
