The value of left ventricular Tei Index in evaluating the cardiac function and prognosis of patients with sepsis-induced cardiomyopathy / 中华急诊医学杂志

ABSTRACT

Objective To determine whether left ventricular Tei Index evaluate the cardiac function and prognosis of patients with sepsis-induced cardiomyopathy (SIC).Methods A total of 86 patients with septic shock combined with SIC in the emergency department of Beijing Chaoyang Hospital affiliated to Capital Medical University from July 2014 to June 2016 were recruited and divided into non-survival group (n=35) and survival group (n=51) according to 28-day follow-up.Left ventricular Tei Index, BNP, cTNI and left ventricular ejection fraction within the first 24 h after admisson were detected and compared between the two groups.The correlations of left ventricular Tei Index to BNP, cTNI and ejection fraction were analyzed.The receiver operating characteristic curves (ROC) were constructed to analysize the value of Tei Index in evaluating the cardiac function and prognosis.Results The patientsin the non-survival group had a higher Tei Index compared with that in the survival group [(0.75±0.13) vs.(0.51±0.09), P<0.05].The Tei Index of SIC patients was significantly positively correlated with BNP and cTNI (both P<0.05), and significantly negatively correlated with ejection fraction (P<0.05).The AUC of Tei Index for predicting 28-day mortality in SIC patients was high comapred with that of BNP, cTNI and ejection fraction.Conclusion The left ventricular Tei Index has a reliable value in evaluating the cardiac function and prognosis of patients with SIC.
