14. Right ventricular involvement in anterior myocardial infarction: a tissue Doppler-derived strain and strain rate study
OBJECTIVE: Strain and strain rate imaging is currently the most popular echocardiographic technique that reveals subclinical myocardial damage. There are currently no available data on this imaging method with regard to assessing right ventricular involvement in anterior myocardial infarction. Therefore, we aimed to evaluate right ventricular regional funct

15. Ecocardiografia tecidual em gatos da raça Maine Coon geneticamente testados para a cardiomipatia hipertrófica / Tissue Doppler echocardiography in Maine Coon cats genetically tested for hypertrophic cardiomyopathy
A cardiomiopatia hipertrófica (CMH) é a principal cardiopatia dos felinos e é caracterizada por hipertrofia miocárdica concêntrica, sem dilatação ventricular. Disfunções miocárdicas ocorrem em gatos com CMH, mas pouco se conhece a respeito destas alterações nos estágios iniciais da afecção. Em gatos da raça Maine Coon, a mutação no gene MyB

16. Typical and atypical enteropathogenic Escherichia coli bacterial translocation associated with tissue hypoperfusion in rats
Although enteropathogenic Escherichia coli (EPEC) are well-recognized diarrheal agents, their ability to translocate and cause extraintestinal alterations is not known. We investigated whether a typical EPEC (tEPEC) and an atypical EPEC (aEPEC) strain translocate and cause microcirculation injury under conditions of intestinal bacterial overgrowth. Bacterial

17. Statin therapy blunts inflammatory activation and improves prognosis and left ventricular performance assessed by Tissue Doppler Imaging in subjects with chronic ischemic heart failure: results from the Daunia Heart Failure Registry
BACKGROUND: A limited number of studies have used Tissue Doppler Imaging (TDI) to evaluate the effect of statin therapy on left ventricular dysfunction in patients with chronic heart failure. In this work, we aimed to determine whether statin administration influenced prognosis, inflammatory activation and myocardial performance evaluated by Tissue Doppler I

18. Análise da função diastólica do ventrículo esquerdo em hipertensos sob variação de condições hemodinâmicas provocadas : estudo comparativo entre o doppler transmitral e tissular / Assessment of left ventricular diastolic function in hypertensive patients under different hemodynamic conditions: comparative study between transmitral and tissue doppler echocardiography
OBJETIVO Avaliar o comportamento das velocidades de movimentação diastólica do segmento VE septal posterior basal justa-anular, obtidos pelo Doppler tissular em relação às velocidades do fl uxo transmitral de hipertensos, submetidos à sobrecarga de pré-carga por elevação dos membros inferiores por 5 minutos, e durante 1 minuto de handgrip (condiç�

19. Efeitos da adição de sinvastatina ao enalapril em indivíduos hipertensos com níveis de colesterol limítrofe e disfunção diastólica: um estudo aleatorizado, controlado, duplo-cego, com ecocardiograma e Doppler tecidual de repouso e estresse / Effect of the addition of simvastatin to enalapril in hypertensive individuals with average cholesterol levels and diastolic dysfunction: a randomized, placebo-controlled, double-blind trial, with ecochardiography and tissue Doppler of rest and stres
Background: Diastolic dysfunction (DD) and decreased contractile reserve associated with hypertension are a surrogate for increased cardiovascular risk. Statins have experimental benefits on myocardial fibrosis, and could improve diastolic function or contractile reserve to a greater extend than ACE-inhibitors in hypertension. Objectives: Test in a double-bl

20. Effect of maintenance hemodialysis on diastolic left ventricular function in end-stage renal disease
PURPOSE: To analyze the effect of maintenance hemodialysis on left ventricular diastolic function in patients with end-stage renal disease. METHODS: Study population consisted of 42 patients with end-stage renal disease. Before an arteriovenous fistula was surgically created, the patients were evaluated by conventional and Doppler echocardiography and Dopple

21. Left atrioventricular remodeling in the assessment of the left ventricle diastolic function in patients with heart failure : a review of the currently studied echocardiographic variables
Multiparametric echocardiographic imaging of the failing heart is now increasingly used and useful in decision making in heart failure. The reasons for this, relies on the need of different strategies of handling these patients, as differentiation of systolic or diastolic dysfunction, as well as on the gamma of approaches available, such as percutaneous and

22. Imaging of the acute scrotum: is there a place for contrast-enhanced ultrasonography?
Purpose: To present and evaluate the findings of contrast-enhanced ultrasonography (CEUS) in typical cases of acute painful scrotum. Materials and methods: Nineteen patients aged from 19 to 61 years old were included in the study. All patients underwent grey-scale and color Doppler ultrasonography (US) of the scrotum, followed by imaging after i.v. administr

23. O ecocardiograma como preditor de variáveis hemodinâmicas nas cardiopatias congênitas com hipertensão pulmonar e nos candidatos a transplante cardíaco / Echocardiographyc estimates of hemodynamic parameters in pulmonary hypertension associated with congenital cardiac shunts or cardiomyopathy
Pulmonary hypertension is defined as a mean pulmonary arterial pressure of >25 mmHg registered at rest, during cardiac catheterization. A number of conditions have been demonstrated to cause pulmonary hypertension, including congenital (septal defects) and acquired heart diseases, chronic lung disease, connective-tissue disease, thromboembolic disorders, sch

24. Alterações cardiometabólicas em mulheres hipertensas com obesidade abdominal / Cardiometabolic alteration in hypertensive women with abdominal obesity
Observational studies have demonstrated that weight gain and increase of abdominal circumference are important prognostic indexes in hypertension, and abdominal obesity is a relevant marker of increased cardiovascular risk. The purpose of this study was to identify metabolic and cardiac alterations in a sample of non-diabetic hypertensive women with abdomina
