Noninvasive Estimation of Left Ventricular Diastolic Filling Pressure From Doppler Tei Index

Abstract

Attempts to predict left ventricular (LV) diastolic filling pressure from LV function have not been feasible because patients with LV dysfunction do not always have high LV filling pressure. As shown in

Functional Assessment by Myocardial Performance Index (Tei Index) Correlates With Plasma Brain Natriuretic Peptide Concentration in Patients With Hypertrophic Cardiomyopathy

“…37 However, Zhang et al reported that Tei index is useful in the differentiation of normal from pseudonormal/restrictive mitral inflow pattern, suggesting that measurement of Tei index has a complementary role in addition to the measurement of mitral E/A ratio. 39,40 Thus, assessment of both Tei index and E/A ratio might enable a better prediction of plasma BNP level.…”
