Rationale of the SEAS study: Serial Echocardiography After Subarachnoid haemorrhage, a prospective national, multicentre, multidisciplinary, cohort study to evaluate cardiac abnormalities following intracranial haemorrhage

The SEAS study is a prospective national, multicentre, multidisciplinary, cohort study in which the cardiac abnormalities following aneurysmal subarachnoid haemorrhage are studied. Incidence, clinical implications and predictive variables of cardiac abnormalities following aneurysmal subarachnoid haemorrhage will be studied. Cardiac abnormalities are defined as ECG changes, echocardiographic function abnormalities, and biochemical changes. A total of 350 patients will be included over a period of three years including follow-up
