BACKGROUND/AIMS: Cardiac changes observed in chronic kidney disease patients are of multifactorial origin including chronic uremia, hemodynamics or inflammation. Restoration of renal function by kidney transplantation (KTX) may reverse cardiac changes. Novel echocardiographic methods such as speckle tracking echocardiography (STE) allow early and sensitive detection of subtle changes of cardiac parameters. We evaluated changes of cardiac structure and function after KTX by advanced echocardiographic modalities...

Overproduction of thyroid hormones leads to structural as well as functional cardiac changes. Conventional echocardiography but also recently developed sophisticated two-dimensional echocardiography speckle (2D-STE) tracking allow elaborate evaluation of these changes. Our purpose was to investigate the effects of thyroid hormones overproduction on the heart in patients with Graves' disease and changes that occur after 6 months thyrostatic therapy. We conducted a prospective, case-control study of 6 months duration...

OBJECTIVES: This study evaluated whether 2-dimensional speckle-tracking echocardiography (2D-STE) has incremental value for prognosis over traditional clinical, echocardiographic, and serological markers-with main focus on the current prognostic staging system-in light-chain (AL) amyloidosis patients with preserved left ventricular ejection fraction. BACKGROUND: Cardiac amyloidosis (CA) is the major determinant of outcome in AL amyloidosis. The current prognostic staging system is based primarily on serum levels of cardiac troponin T (cTnT), N-terminal pro-B-type natriuretic peptide (NT-proBNP), and free light chain differential (FLC-diff)...

BACKGROUND: Three-dimensional (3D) speckle tracking echocardiography (STE) has been developed to overcome the limitations of two-dimensional (2D) STE and has been applied in the several clinical settings. However, no data exist about the prognostic value of 3DSTE-based strain on clinical outcome after myocardial infarction (MI). This study was designed to investigate the prognostic value of area strain (AS) by 3D speckle tracking in predicting clinical outcome after acute MI. METHODS: We assessed 96 patients (62±14 years, 72% male) with acute MI and who had undergone a coronary angiography...

BACKGROUND: Iron-deficiency anemia (IDA) is a global health problem and a common medical condition that can be seen in everyday clinical practice. And two-dimensional speckle tracking echocardiography (2D-STE) has been reported very useful in evaluating left atrial (LA) function, as well as left ventricular (LV) function. The aim of our study is to evaluate the LA function in patients with IDA by 2D-STE. METHODS: 65 patients with IDA were selected. This group of patients was then divided into two groups according to the degree of hemoglobin: group B (Hb > 90 g/L) and group C (Hb60 ~ 90 g/L)...

Two-dimensional (2D) speckle-tracking echocardiography (STE) has clarified functional adaptations accompanying the morphological features of 'athlete's heart'. However, 2D STE has some limitations, potentially overcome by three-dimensional (3D) STE. Unfortunately, discrepancies between 2D- and 3D STE have been described. We therefore sought to evaluate whether dimensional and functional differences exist between athletes and controls and whether 2D and 3D left ventricular (LV) strains differ in athletes. One hundred sixty-one individuals (91 athletes, 70 controls) were analysed...

Subclinical left ventricular (LV) dysfunction refers to subtle abnormalities in the LV function that typically precede a reduction in the left ventricular ejection fraction (LVEF). The assessment of myocardial function using LVEF, a radial metric of function, is subject to load dependence, intra-observer and inter-observer variability. Reductions in LVEF typically manifest late in the disease process thus compromising the ability to intervene before irreversible impairment of systolic performance sets in. 2-Dimensional speckle tracking echocardiography (2D-STE), a novel strain imaging modality has shown promise as a sensitive indicator of myocardial contractility...

BACKGROUND: Heart failure with preserved ejection fraction (HFpEF) is a syndrome in which patients have symptoms and signs of heart failure but preserved ejection fraction. Left atrial (LA) volume and function are known to be impaired in these patients. Two-dimensional speckle-tracking echocardiography (2D-STE) has recently enabled the quantification of LA deformation dynamics. In this study, we evaluated the use of 2D-STE for the diagnosis of HFpEF. PATIENTS AND METHODS: The study included 83 patients with suspected HFpEF...

BACKGROUND: Transthoracic echocardiography is the most commonly used tool for the detection of left ventricular wall motion (LVWM) abnormalities using "naked eye evaluation". This subjective and operator-dependent technique requires a high level of clinical training and experience. Two-dimensional speckle-tracking echocardiography (2D-STE), which is less operator-dependent, has been proposed for this purpose. However, the role of on-line segmental longitudinal peak systolic strain (LPSS) values in the prediction of LVWM has not been fully evaluated...

Speckle tracking echocardiography (STE) is a widespread method for calculating myocardial strains and estimating left ventricle function. Since echocardiographic clips are corrupted by speckle decorrelation noise, resulting in irregular, nonphysiological tissue displacement fields, smoothing is performed on the displacement data, affecting the strain results. Thus, strain results may depend on the specific implementations of 2-D STE, as well as other systems' characteristics of the various vendors. A novel algorithm (called K-SAD) is introduced, which integrates the physiological constraint of smoothness of the displacement field into an optimization process...

BACKGROUND: Identification of transmural extent and degree of non-viability after ST-segment elevation myocardial infarction (STEMI) is clinically important. The objective of the present study was to assess the regional mechanics and temporal deformation patterns using speckle tracking echocardiography (STE) in acute and later phases of STEMI to predict myocardial damage in these patients. METHODS AND RESULTS: Ninety-eight patients with first STEMI underwent both echocardiography and cardiac magnetic resonance imaging in acute phase and at 6 months follow-up with 2D STE-derived measurements of peak longitudinal strain (PLS), Pre-STretch index (PST) and post-systolic deformation index (PSI)...

Left atrial (LA) function has a significant impact on cardiovascular diseases and has been assessed by several noninvasive methods. However, several limitations, including the dependence of image quality, single plane assessment, and time-consuming procedures, have prevented widespread clinical application of the assessment of LA function. Strain imaging using tissue Doppler echocardiography enables quantification of LA function. Recently, two-dimensional speckle tracking echocardiography (2D-STE) has been developed as a noninvasive, simple, and reproducible tool for assessment of LA function in patients with cardiovascular disease...
