Distribution of potential cardiac sources of embolism in young and older stroke patients: implications for recurrent vascular events.
Journal of Cardiovascular Medicine 2006 March
BACKGROUND: Transesophageal echocardiography (TEE) has improved the diagnostic evaluation of ischemic stroke patients, permitting detection of potential cardiac sources of embolism. The present study aimed to evaluate the distribution of potential cardioembolic sources in young versus older stroke patients and their clinical implication for recurrent vascular events. Two hundred and twenty-eight patients with undetermined ischemic stroke were enrolled in the study.
METHODS: All patients were submitted to transthoracic and to TEE examination. The mean follow-up period was 43 +/- 19 months.
RESULTS: The overall detection of cardiac sources of embolism was significantly higher in younger than in older patients (P = 0.006). Atrial septal abnormalities were more prevalent in the younger than in the older population (P = 0.006), whereas complicated aortic plaques were detected more often in older patients. During the follow-up period of 4-5 years, we identified 40 recurrent stroke episodes or vascular deaths. As expected, there was a significant difference in recurrent vascular events and death of older patients compared to the younger ones (P = 0.025).
CONCLUSIONS: The present study demonstrates that atrial septal abnormalities and aortic atheromas are the most prevalent echocardiographic findings in young and elderly stroke patients, respectively. Complicated aortic atheroma is strictly correlated with recurrent cerebral vascular events or death.
