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

The degree of newly emerging mitral regurgitation during off-pump coronary artery bypass is predicted by preoperative left ventricular function

“…Both the Tei index and serum BNP level are easy to measure, and they are useful for evaluating combined LV systolic and diastolic function. Our present data showed a signifi cant correlation between serum BNP level and the Tei index, which is consistent with previous reports [18,19]. Our results also confi rm that we need to evaluate both systolic and diastolic function preoperatively to predict hemodynamic changes during OPCAB.…”

Tissue Doppler Imaging and Plasma BNP Levels to Assess the Prognosis in Patients with Hypertrophic Cardiomyopathy

“…The magnitude and distribution of LV hypertrophy were also assessed in the parasternal short-axis plane by diving the ventricle into four equal segments (anterior septum, posterior septum, lateral wall, and posterior wall) at the level of the mitral valve, papillary muscles, and two segments (anterior and posterior) at the apical level, as previously reported. 16 The greatest wall thickness in any of the 10 segments in the left ventricle was regarded as the maximum wall thickness. Peak instantaneous outflow pressure gradient was measured at rest using continuous-wave Doppler imaging, and an LV outflow gradient $ 30 mm Hg was considered significant.…”

Left Ventricular Remodeling of Hypertrophic Cardiomyopathy Longitudinal Observation in a Rural Community

“…30,31 Recently, we reported that myocardial performance index (TEI index), that reflected both systolic and diastolic functions, was abnormal and correlated with plasma B-type natriuretic peptide level in patients with HCM. 22 Thus, those newly developed echocardiographic parameters in patients with HCM might add the more clinical and prognostic information. Further studies are needed.…”
