One-hundred and ten patients referred for echocardiography to exclude a cardiac source of cerebral emboli were prospectively studied. Four patients with known cardiac abnormalities, for which they were receiving inadequate anticoagulation, were excluded from the study, and 18 patients were subsequently found to have a non-embolic cause for their cerebral pathology. Twenty-eight patients with a normal clinical examination, chest X-ray and electrocardiogram, and 27 patients with hypertension alone had echocardiograms which did not reveal a cardiac source of embolus. Of the remaining group of 33 patients, six were found to have a probable cardiac source of embolus and nine had abnormalities which may be associated with cerebral emboli. Echocardiography may not be indicated in patients with a normal clinical examination, chest X-ray and electrocardiogram, and in patients with hypertension alone. However, if these patients are excluded echocardiography gives a high yield of positive findings which may be of practical importance in the management of the patient.
对110例因排除脑栓塞心脏来源而转诊进行超声心动图检查的患者进行了前瞻性研究。4例已知有心脏异常且抗凝治疗不足的患者被排除在研究之外，随后发现18例患者的脑部病变有非栓塞原因。28例临床检查、胸部X线和心电图正常的患者，以及27例仅患有高血压的患者，其超声心动图未显示栓子的心脏来源。在其余33例患者中，6例被发现可能有栓子的心脏来源，9例有可能与脑栓塞相关的异常。对于临床检查、胸部X线和心电图正常以及仅患有高血压的患者，可能不需要进行超声心动图检查。然而，如果排除这些患者，超声心动图检查的阳性发现率很高，这在患者的管理中可能具有实际意义。
