Risk factors for lacunar stroke: a case-control transesophageal echocardiographic study
1National Stroke Research Institute, Austin & Repatriation Medical Centre, Victoria, Australia.
Abstract:
To reassess the independent risk factors for lacunar stroke and to clarify the role of potential embolic sources, we conducted a case-control study using transesophageal echocardiography and duplex ultrasonography. Among 62 consecutive patients with their first lacunar stroke and 202 normal controls, we found that hypertension (p < 0.001), smoking (p = 0.001), and aortic arch atheroma (p = 0.006) were independently associated with an increased risk of lacunar stroke. Whether proximal aortic arch atheroma is mechanistically associated with lacunar stroke or merely coexistent is uncertain.
