BACKGROUND AND OBJECTIVES Although the Tei index is a useful predictor of global ventricular function, it has not been investigated at the level of regional myocardial function. We therefore investigated the segmental tissue Doppler image derived-Tei index (TDI-Tei index) in patients with regional wall motion abnormalities. SUBJECTS AND METHODS We(More)
OBJECTIVES This study was aimed at evaluating the usefulness of giant negative T-wave (GNT) as an index of apical hypertrophic cardiomyopathy (ACM) severity and as a better echocardiographic index to represent apical hypertrophy. METHODS Seventy-five patients who were recently diagnosed with ACM by echocardiography were enrolled in this study. ACM(More)
Cardiac amyloidosis describes a clinical disorder caused by infiltration of abnormal insoluble fibrils in the heart, characterized by progressive heart failure and a grave prognosis. Pleural effusion in cardiac amyloidosis may represent a sign of heart failure, but it can also result from pleural infiltration of amyloid, manifested by recurrent large fluid(More)
BACKGROUND AND OBJECTIVES The cut-off value of diastolic dysfunction by tissue Doppler imaging (TDI) is affected by aging and modalities used (pulsed-wave vs. color-coded). The purpose of this study was to investigate the diastolic function of healthy elderly people and to determine the appropriate cut-off value of diastolic dysfunction in elderly(More)
