[The myocardial performance index (Tei-Index): correlation with seric NTproBNP levels in patients with dilated cardiomyopathy].

Unlabelled: A combined myocardial performance index (isovolumic contraction time plus isovolumic relaxation time divided by ejection time, 'Tei-Index') has been applied in the echocardiographic evaluation of patients with dilated cardiomyopathy (DCM). N-terminal pro brain natriuretic peptide (NTproBNP) is released from the left ventricular (LV) in response tomyocite stretch and is a powerful prognostic marker for heart failure.

Aim: To assess the correlation between Tei index and NTproBNP level in patients with DCM.
