[Patients with transient ischemic attacks. Their cardiac status and its prognostic significance].
In 51 consecutive patients with acute transitory cerebral ischaemia cross-sectional echocardiograms, 24-hour electrocardiograms (ECG) and exercise ECGs were recorded. The subsequent observation period averaged 13 (3-30) months. The echocardiogram was abnormal in 27 of 46 patients (58%). A holosystolic mitral-valve prolapse was found in eight: cerebral ischaemia recurred in five. There was no correlation between arrhythmias in the 24-hour ECG and renewed cerebral ischaemia. In addition to the 14 patients who--according to history and resting ECG--had already had a myocardial infarction, the exercise ECG revealed probably coronary heart disease in a further 11, i.e. half of the patients had coronary heart disease. Renewed attacks of cerebral ischaemia occurred in 13 patients during the follow-up period; four patients died, all of them also having had coronary heart disease. Because of the high prevalence of coronary heart disease (often previously undiagnosed) in the whole group, routine exercise ECGs are recommended for patients with transitory ischaemic attacks, protracted ischaemic neurological deficit or "minimal stroke", while 24-hour ECG monitoring does not seem essential. Randomized trials are needed to determine whether patients with cerebral ischaemia and echocardiographic evidence of mitral-valve prolapse should be treated prophylactically.
