Abstract
To describe the clinical features of cardioembolic infarcts. Cardioembolic infarct was diagnosed in 231 (15.4%) of 1500 consecutive stroke patients included in a prospective stroke registry over an 8-year period. Cardiac sources of emboli included isolated atrial dysrhythmia (57.1%), valvular heart disease (20.3%), and coronary artery disease (18.2%). Patients with cardioembolic stroke showed a significantly higher (P < 0.00001) frequency of sudden onset of neurological deficit (79.7%) and altered consciousness (31.2%) than patients with lacunar infarct (38% and 1.9%) and atherothrombotic infarction (46% and 24%). Eleven patients had a spectacular shrinking deficit and 6 a presumed cardioembolic lacunar infarct. Early recurrent embolisms occurred in 6.5% of patients mostly (60%) within 7 days of initial embolism. In-hospital mortality was 27.3% (0.8% in lacunar infarcts, 21.7% in atherothrombotic infarction, P < 0.00001). Cardioembolic infarction is a severe subtype of stroke with a high risk of early death. Clinical features at stroke onset may help clinicians to differentiate cerebral infarction subtypes and to establish prognosis more accurately.This publication has 49 references indexed in Scilit:
