[Cardiologic diagnostics after stroke: what is really important?].

Patients with a stroke often exhibit similar risk factors compared to patients with coronary artery disease. The morbidity and mortality of patients surviving a stroke are strongly determined by cardiac co-morbidities. Moreover, ischemic stroke frequently results from cardiac embolism. Thus, for risk assessment and prevention of cardiovascular events patients should undergo cardiac evaluation after a stroke. Laboratory testing should include blood glucose, coagulation parameters, blood cell count and in the case of suspected acute coronary syndrome cardiac ischemic markers. Assessment of the lipid profile is useful to determine the overall cardiovascular risk. In all patients with a stroke an ECG should be recorded. In those with normal ECG and suspected thromboembolic stroke additional Holter is helpful to detect possible atrial fibrillation. Echocardiography should be performed in all patients with suspected cardioembolic stroke. Moreover, echocardiography may establish the diagnosis of structural heart disease, which has a major impact on prognosis in patients with a stroke.
