[Indications for the long-term electrocardiogram and echocardiogram after a cerebral ischemia complication].
Ninety patients admitted to a neurology unit for cerebral ischaemic accident without evidence of embolism from the heart were examined by ambulatory electrocardiographic monitoring (AEM) and by echocardiography assessable in 76 cases. On the basis of a standard cardiac evaluation (SCE) including physical examination, chest radiography and electrocardiography, the patients were divided into 3 groups: 42 with normal SCE (group I), 19 with isolated arterial hypertension (group II) and 36 with patent cardiac disease (group III). Significant abnormalities were detected by AEM in 10.5% of group I patients, 18.5% of group II patients and 33% of group III patients. A structural cardiopathy was discovered at echocardiography in 33%, 62% and 91% respectively of patients in these 3 groups. The greatest number of mitral valve prolapses (7/9 cases) was found in group I. The main echocardiographic abnormality detected in group II was dilatation of the left cardiac cavities: atrium more than 38 mm in 8 cases, ventricle more than 50 mm in 3 cases. Comparisons between the two explorations showed that arrhythmias were often associated with dilatation of the left cardiac cavities (39%) and much less frequently with mitral valve prolapse (11%) and myocardial hypertrophy (16%). Our results suggest that when examinations cannot be routinely performed in hospital patients with a cerebral ischaemic accident echocardiography should be reserved to patients with heart disease or hypertension, and AEM to those with heart disease or hypertension and with dilatation of the left cardiac cavities.
