Assessment of left ventricular function and Tei index by tissue Doppler imaging in patients with slow coronary flow.

Background: The aim of this study was to assess left ventricular (LV) function and the Tei index by tissue Doppler imaging (TDI), and also to evaluate the relationship of thrombolysis in myocardial infarction (TIMI) frame count (TFC) with the Tei index and LV function in patients with slow coronary flow (SCF).

Methods: We prospectively evaluated 50 patients with SCF and 27 control subjects. Diagnosis of SCF was made by TFC.
