Abstract:
OBJECTIVE: Among risk factors associated with cerebral infarction, cardiac factors are well known to be very important. However there were only few studies related to correlation between cardiac risk factors and stroke recurrence. So we tried to evaluate cardiac disease as a risk factor of recurrent cerebral infarction. METHOD: Subjects were 118 patients (62 male, 56 female) with cerebral infarction and were divided into first attack group as a control and recurred group. We evaluated the results of transesophageal echocardiographic study and other major risk factors and the results were compared in two groups using X2 test. RESULTS: Control group was 75 patients (39 male, 36 female), and recurred group was 43 patients (23 male, 20 female) and the mean ages were 62.8 years and 66.7 years, respectively. General transesophageal echocardiographic abnormalities were shown in 63 cases (84%) in control group and 40 cases (93%) in recurred group. Among the abnormal transesophageal echocardiographic findings, atherosclerosis of aorta was significantly higher in recurred group (49%) compared to control group (25%) (p<0.05), but there were no significant difference in aortic valve calcification, mitral calcification etc. Among the major risk factors of cerebral infarction, hypertension, diabetes, hyperlipidemia, and alcohol intake showed tendency of high incidence in the recurred group. Patients with abnormal EKG findings concurrent with abnormal transesophageal echocardiographic findings showed in 33 cases (44%) in control group, and 24 cases (56%) in recurred group, but there's no statistical significance. CONCLUSION: Our results do not support the hypothesis that TEE would be able to diagnose the cardiac risk factor for recurred cerebral infarction. However, the prevalence of atherosclerosis of aorta was significantly higher in recurrent group, so further studies would be needed.
