Correlation between Global Longitudinal Strain (GLS)-Left Ventricle and TEI Index (TI) with Seattle Heart Failure Model (SHFM) Score in Chronic Heart Failure Patients with Systolic Dysfunction

Abstract

Assessment of left ventricular function in patients with chronic heart failure is important for determining prognosis and treatment plans. The prognostic values of the myocardium and global ventricular functions remain unclear. This cross-sectional study included 30 subjects obtained through purposive sampling. Global longitudinal strains (GLS) is used to assess the left ventricular systolic function and Tei index (TI) is used to assess both global systolic and diastolic ventricular function. SHFM scoring was calculated based on existing patient data. The mean GLS-left ventricle value was-8.08 ± 3.98, whereas TI value was 0.65 ± 0.14. GLS-left ventricle had significant negative correlation with estimated one and five years mortality based on SHFM score (r =-0.676 and p = 0.0001) whereas TI had a significant positive correlation (r = 0.745 and p = 0.0001; r = 0.738 and p = 0.0001). GLS-left ventricle had a significant negative correlation with an estimated one and five years mortality based on SHFM score, whereas TI had a significant positive correlation. Hence it is suggested that GLS-left ventricle and TI can be a prognostic factor.
