1. Importance of epicardial adipose tissue as a predictor of heart failure with preserved ejection fraction
SUMMARY OBJECTIVE: Epicardial adipose tissue is a special form of visceral fat surrounding the heart. It is associated with cardiac and metabolic diseases. Epicardial adipose tissue is associated with risk factors for heart failure with preserved ejection fraction, such as obesity, metabolic syndrome, hypertension, and diabetes. In this study, we examined t

2. Cardiac parameters and endothelial function in a strength athlete: a case report
Abstract Aims: We aimed to discuss a case of strength training athlete who competes in international competitions regarding cardiac (dimension and function), vascular (endothelium and vascular resistance), hemodynamic (blood pressure), given limited evidence supporting these cardiovascular adaptations as well as concerning endothelial function in long-term

3. Estudo experimental comparativo entre a derivação cavo-pulmonar associada ao suporte circulatório esquerdo e o suporte circulatório biventricular na falência aguda biventricular / Comparative experimental study between cavopulmonary anastomosis associated with left ventricular assist device support and biventricular circulatory assistance in acute biventricular failure
Background Right ventricular (RV) failure durinq left ventricular assist device (LVAD) support can result in severe hernodynarnic cornpromise with hiqh mortality. Objective: This study investiqated the acute effects of cavopulmonary anastomosis on L VAD performance and riqht ventricular myocardial compromise in comparison with isolated LVAD support and biven

4. Avaliação experimental do metabolismo energético em dois protocolos de sobrecarga sistólica do ventrículo direito / Experimental evaluation of energy metabolism in two right ventricle systolic overload protocols
Objective: Altered energy metabolism has been identified in myocardial hypertrophy. Some processes are considered beneficial, whereas others are linked to heart failure. The purpose of this study was to compare the activity of three different energy metabolism enzymes in two different protocols of right ventricle (RV) systolic overload in young goats. Method

5. Avaliação da fibrose miocárdica pela ressonância magnética cardíaca na doença valvar aórtica grave: validação de um algoritmo de quantificação e comparação com a histopatologia / Assessment of myocardial fibrosis by cardiac magnetic resonance imaging in severe aortic valve disease: validation of a quantitative algorithm and comparison with histopathology
Introduction: Severe aortic valve disease is characterized by a process of progressive accumulation of interstitial fibrosis in the myocardial tissue. It has been shown that the amount of interstitial myocardial fibrosis can play an important role in the transition from well-compensated hypertrophy to overt heart failure in the setting of chronic left ventri

6. ROLE OF RENIN ANGIOTENSIN SYSTEM ON CARDIOVASCULAR CHANGES IN EXPERIMENTAL DIABETES: IN VIVO AND IN VITRO EVALUATION. / PAPEL DO SISTEMA RENINA ANGIOTENSINA NAS ALTERAÇÕES CARDIOVASCULARES DO DIABETES EXPERIMENTAL: AVALIAÇÕES IN VIVO E IN VITRO.
The aim of the present study was to elucidate the role of renin angiotensin system, by in vivo and in vitro evaluation, on cardiac dysfunction induced by streptozotocin experimental diabetes. Male Wistar rats (250-300g) were divided in 4 groups: control (n=9), control + Enalapril, (n=7, 1mg/Kg), diabetic (n=7, STZ, 50mg/Kg ev), and diabetic + Enalapril (n=7)

7. Avaliação dos mecanismos adaptativos do miocárdio durante sobrecarga de pressão induzida com o uso de bandagem do tronco pulmonar: participação da proliferação celular / Assessment of myocardial adaptive mechanisms during pressure overload induced by pulmonary artery banding: contribution of cell proliferation
INTRODUCTION: Rapid ventricular conditioning induced by pulmonary artery banding (PAB) has been indicated to those patients with transposition of the great arteries (TGA) who have lost the chance for arterial switch operation ? Jatene?s procedure ? aiming at induce myocardial mass increase. However, with time, hypertrophied chamber may exhibit contractile dy

8. Monitoração ecocardiográfica da atriosseptostomia com balão
Objective: Balloon atrial septostomy (BAS) is a life-saving palliative procedure for some congenital heart defects and typically performed in the cardiac catheterization laboratory. The aim of this study was to evaluate BAS under echocardiographic guidance. Method: From August 1997 through January 2004, 31 children with congenital heart defects with indicati

9. Subendocardial fibrosis in remote myocardium results from reduction of coronary driving pressure during acute infarction in rats
OBJECTIVE: To investigate the role of hemodynamic changes occurring during acute MI in subsequent fibrosis deposition within non-MI. METHODS: By using the rat model of MI, 3 groups of 7 rats each [sham, SMI (MI <30%), and LMI (MI >30%)] were compared. Systemic and left ventricular (LV) hemodynamics were recorded 10 minutes before and after coronary artery li

10. The effect of siesta in parameters of cardiac structure and in interpretation of ambulatory arterial blood pressure monitoring
OBJECTIVE: To evaluate the influence of the siesta in ambulatory blood pressure (BP) monitoring and in cardiac structure parameters. METHODS: 1940 ambulatory arterial blood pressure monitoring tests were analyzed (Spacelabs 90207, 15/15 minutes from 7:00 to 22:00 hours and 20/20 minutes from 22:01 to 6.59hours) and 21% of the records indicated that the perso

11. Morphogenesis of univentricular hearts.
Two main theories exist for the explanation of univentricular hearts. One states that the bulboventricular septum becomes realigned to form the interventricular septum, and that univentricular hearts are a consequence of failure of this realignment. The other states that bulboventricular and interventricular septa are different structures, and that the unive

12. Intra-uterine closure of the atrial septum
Two newborn babies with an intact atrial septum are described. In one, the two components of the atrial septum appeared to have become fused after relatively normal initial development; the left side of this heart was hypoplastic. In the other baby the formation of the atrial septum appeared to have been completely anomalous; this heart showed mitral atresia
