Therapy implications of transthoracic echocardiography in acute ischemic stroke patients.

چکیده
BACKGROUND AND PURPOSE Stroke is the third leading cause of death in most Western countries. Cardioembolism might be responsible for 15% to 20% of ischemic strokes. Although atrial fibrillation can be diagnosed by electrocardiography, the remaining causes of cardioembolic stroke are diagnosed by echocardiography. Recent recommendations on the management of acute ischemic stroke fail to consider echocardiography as an essential test in all patients. METHODS We conducted a prospective observational study, performing transthoracic echocardiography on all patients admitted in our hospital with ischemic stroke, in sinus rhythm, from January 7, 2002, to October 16, 2003. Findings compatible with heart diseases that would indicate anticoagulation as beneficial were identified. RESULTS Of the 853 patients admitted with ischemic stroke, transthoracic echocardiography was performed on 846 (99.2%). Of the 435 patients with ischemic stroke, in sinus rhythm, 37.2% had findings indicating anticoagulation as beneficial: dilated cardiopathy (19.1%), previous anterior wall myocardial infarction (6.2%), left ventricular systolic dysfunction with an ejection fraction <35% (3.7%), mitral valve stenosis with enlarged left atria (1.6%), intracardiac masses (0.5%), valvular prosthesis (0.2%), and >1 abnormality (5.5%). CONCLUSIONS In our study, transthoracic echocardiography had therapy implications in 37.2% of ischemic stroke patients in sinus rhythm. Transthoracic echocardiography should be considered an essential test in all ischemic stroke patients in sinus rhythm.

BACKGROUND The role of transesophageal echocardiography (TEE) in the evaluation of acute stroke patients is still ill-defined. We conducted a prospective observational study to find the prevalence of TEE findings that indicate anticoagulation as beneficial, in acute ischemic stroke patients without indication for anticoagulation based on clinical, electrocardiographic and transthoracic echocard...

Background: Thrombolytic therapy is the only approved treatment for acute cerebral ischemia. The hemorrhagic transformation is the greatest complication of this treatment, which may occur after recanalization of occluded artery.

متن کاملForamen Ovale in Stroke Patients
Background and Purpose: The prevalence of a patent foramen ovale has been shown to be increased in patients with ischemic stroke. Transesophageal echocardiography, transthoracic echocardiography, and transcranial Doppler examination with contrast injection can all be used to search for a patent foramen ovale. We compared the accuracy of these techniques for identifying a patent foramen ovale in...

A 56-year-old healthy male with no obvious risk factors or significant past medical history was admitted to the emergency room with acute ischemic stroke. On his transthoracic echocardiography (TTE), an extremely large thrombus was detected at the apex involving the distal anterior wall. The thrombus was predominantly adherent but with a mobile tip. The patient was subsequently managed with dua...
