abstract introduction: doppler echocardiography is used to evaluate global myocardial performance. an index of myocardial performance (tei index) can be of great prognostic value in heart failure. this study was performed to assess the correlation between tei index (ti) and left ventricular end diastolic pressure (lvedp). methods: the study group consisted of 38 patients. each patient underwent...
although involvement of the heart by malignant lymphoma is relatively common, it is unusual to be detected premortem. we report a case of hodgkin's lymphoma who presented with systemic signs and symptoms including abdominal distension, weakness, pallor, chills and fever, hepatosplenomegaly and generalized lymphadenopathy as well as signs of heart failure. echocardiography revealed lucent myocar...
Background: Advanced glycation end-products (AGEs) came up with the recent researches regarding new biomarkers for the diagnosis of heart failure. AGEs are the end products of non-enzymatic glycation and oxidation of proteins, lipids and nucleotides during Maillard biochemical reaction. Although it has been known that AGEs have a role in the pathogenesis of chronic heart failure (CHF), informat...
Reliable diagnosis of congenital heart defects and arrhythmias in utero has been possible since the introduction of fetal echocardiography. The nation-wide prenatal ultrasound screening program in the Czech Republic enabled detection of cardiac abnormalities in 1/3 of patients born with any congenital heart disease and up to 83 % of those with critical forms. Prenatal frequency of individual he...
OBJECTIVES To quantify the short term haemodynamic effects of biventricular pacing in patients with heart failure and left bundle branch block by using three dimensional echocardiography. DESIGN Three dimensional echocardiography was performed in 15 consecutive heart failure patients (New York Heart Association functional class III or IV) with an implanted biventricular pacing system. Six min...
BACKGROUND Heart block is associated with pulmonary hypertension, and the aim of the study was to test the hypothesis that the heart block is the result of a change in the ion channel transcriptome of the atrioventricular (AV) node. METHODS AND RESULTS The most commonly used animal model of pulmonary hypertension, the monocrotaline-injected rat, was used. The functional consequences of monocr...
conclusions gated spect mpi has a good correlation with echocardiography for the measurement of left ventricular ef, edv, and esv in patients with severe heart failure. however, the absolute values of these functional parameters from echocardiography and gated spect mpi measured with different software packages should not be used interchangeably. results a good correlation was found between ech...
background two-dimensional (2d) strain is a new reproducible technique for assessing regional myocardial function; however, its application for evaluation of left atrium (la) function is less studied. objectives we sought to assess la function in heart failure patients using velocity vector imaging (vvi). patients and methods thirty five patients (mean age: 43.34 ± 18.1 years, 59.3% male) with ...
Data from echocardiography provide a cornerstone in the management of heart failure. All imaging techniques can provide an ejection fraction, but the versatility of echocardiography makes it unique in the provision of volumes, diastolic function, right ventricular function, hemodynamics, and valvular regurgitation. The early detection of heart failure has been facilitated by the assessment of g...
