AI InsightTissue Doppler-derived Tei index values did not differ significantly between the two groups (0.42 ± 0.09 vs0.46 ± 0.12, p = 0.25).Conclusion: The Tei index is inadequate for predicting the risk of developing nephropathy in patients at risk for contrast inducednephropathy with preserved ejection fraction.

Abstract
Aim: Contrast induced nephropathy (CIN) is associated substantially with a risk of morbidity and mortality. The aim of this study wasto assess the left ventricular myocardial performance assessed by ‘Tei index’ on the development of contrast induced nephropathyin patients underwent coronary angiography.Material and Methods: Study population consist of patients who underwent coronary angiography and/or percutaneous coronaryintervention and baseline creatinine level 1 mg/dl above and/or having diabetes mellitus. 51 patient were included the study. Patientsdivided into two groups as CIN developed or not. CIN was defined as %25 and/or 0.5 mg/dl increase in basal serum creatinine levelsafter 48-72 hours exposure to contrast media. Conventional and tissue Doppler echocardiography was performed in all patientsprior to angiography. Tei index was calculated from tissue Doppler echocardiography data.Results: Two groups were defined as CIN-developed group (n =13, 62.5 ± 6.8 ) and CIN-undeveloped (n=38, 62.4±9.6 )group. Exceptgender, there is no difference in demographic characteristics between the study groups. Left ventricular (LV) systolic function suchas ejection fraction and tissue Doppler imaging Sm and basic LV diastolic function (E/A, Em/Am, DT) parameters were found to besimilar in both groups. Tissue Doppler-derived Tei index values did not differ significantly between the two groups (0.42 ± 0.09 vs0.46 ± 0.12, p = 0.25).Conclusion: The Tei index is inadequate for predicting the risk of developing nephropathy in patients at risk for contrast inducednephropathy with preserved ejection fraction.
