Abstract
Objective: Myocardial performance index (MPI) is an easily measured index for the assessment of global heart function, combining both systolic and diastolic components. It can be derived from both pulsed wave Doppler (PWD) and tissue Doppler imaging (TDI) and is defined as the sum of the isovolumic contraction time (ICT) and the isovolumic relaxation time (IRT) divided by the ejection time (ET). MPI has been shown to be independent of HR, blood pressure, loading conditions and the geometry of the ventricles. In this study, we aimed to investigate the relation between left ventricular myocardial performance index and National Institutes of Health Stroke Scale (NIHSS) score in acute ischemic stroke patients.
