relation between parameters of myocardial mechanics and ventricular arterial coupling: a three-dimensional speckle-tracking study in healthy adults
objectives our aim was to study the relation between vac and the parameters of myocardial mechanics using three-dimensional speckle-tracking echocardiography (3dste). patients and methods we studied 68 normal participants (mean age, 35 ± 12.2 y; 36 [53%] males). vac was measured by the ratio of arterial elastance (ea) to ventricular elastance (ees). the peak systolic value of longitudinal strai...
متن کاملLeft ventricular strain and strain rate by two-dimensional speckle tracking echocardiography in patients with subclinical hypothyroidism.
AIM Subclinical hypothyroidism (SH) is an asymptomatic condition defined by increased serum thyroid-stimulating hormone (TSH) with normal free thyroid hormone levels. Heart is a major target organ for thyroid hormone action. The aim of this study was to evaluate cardiac functions in patients with SH by speckle tracking imaging. PATIENTS AND METHODS We included 23 consecutive patients with unt...
متن کاملSubclinical left ventricular dysfunction in Behcet's disease assessed by two-dimensional speckle tracking echocardiography.
AIMS The aim of this study was to evaluate the left ventricular (LV) systolic strain by speckle tracking echocardiography (STE) in order to provide the early detection of myocardial dysfunction in patients with Behcet's disease (BD). We also aimed to examine the relationship between LV systolic strain and N-terminal pro-B type natriuretic peptide (NT-proBNP), which is a cardiac biomarker of ven...
متن کاملSubclinical left ventricular systolic dysfunction in patients with severe aortic stenosis: A speckle-tracking echocardiography study.
OBJECTIVE In patients with aortic stenosis (AS), the left ventricular (LV) geometry changes due to the increased LV afterload. However, subclinical myocardial dysfunction can develop despite a normal LV ejection fraction (EF). This study was an investigation of subclinical LV systolic dysfunction in patients with severe AS with a normal LV EF using a strain imaging method, speckle-tracking echo...
متن کاملSubclinical left ventricular dysfunction in preeclamptic women with preserved left ventricular ejection fraction: a 2D speckle-tracking imaging study.
BACKGROUND Patients with preeclampsia are at risk for cardiovascular disease. Changes in cardiac function are subtle in preeclampsia and are difficult to quantify with conventional imaging. Strain measurements using speckle-tracking echocardiography have been used to sensitively quantify abnormalities in other disease settings. METHODS AND RESULTS We evaluated the feasibility and sensitivity ...
