14. Echocardiographic Correlation between Right Ventricular Function and Left Atrial Volume
Resumo Fundamentos: A relação entre a disfunção diastólica do ventrículo esquerdo (DDVE), seus achados mais importantes, como aumento do átrio esquerdo e hipertrofia ventricular esquerda (HVE), e a função do ventrículo direito (VD) tem pouca documentação na literatura científica. Objetivo: Avaliar a correlação entre o tamanho atrial esquerdo

15. Clinical Significance of Cys-C and hs-CRP in Coronary Heart Disease Patients Undergoing Percutaneous Coronary Intervention
Abstract Objective: To investigate the clinical significance of serum cystatin C (Cys-C) and high-sensitivity C-reactive protein (hs-CRP) in coronary heart disease (CHD) patients undergoing percutaneous coronary intervention (PCI). Methods: One hundred and twenty-eight CHD patients were divided into drug treatment (56 cases) and PCI treatment (72 cases) gr

16. Impact of dexmedetomidine on hemodynamics in rabbits
Abstract Purpose: To evaluate the effects of single intravenous administration of Dexmedetomidine (DEX) on hemodynamics in rabbits. Methods: A total of 32 New Zealand white rabbits were randomly divided into the control group (Group C), Group D1 (2.75 μg/kg), Group D2 (5.5 μg/kg), and Group D3 (8.25 μg/kg) to compare systolic blood pressure (SBP), dias

17. Correlation of transforming growth factor-β1 and tumour necrosis factor levels with left ventricular function in Chagas disease
BACKGROUND Transforming growth factor β1 (TGF-β1) and tumour necrosis factor (TNF) have been implicated in Chagas disease pathophysiology and may correlate with left ventricular (LV) function. OBJECTIVES We determined whether TGF-β1 and TNF serum levels correlate with LV systolic and diastolic functions and brain natriuretic peptide (BNP) serum levels

18. Abnormal diastolic function underlies the different beneficial effects of cardiac resynchronization therapy on ischemic and non-ischemic cardiomyopathy
OBJECTIVES: To investigate the association between diastolic function and the different beneficial effects of cardiac resynchronization therapy in patients with heart failure due to different causes. METHODS: The 104 enrolled patients were divided into an ischemic cardiomyopathy group (n=27) and a non-ischemic cardiomyopathy group (n=77) according to the c

19. Respiratory Muscle Training Improves Diaphragm Citrate Synthase Activity and Hemodynamic Function in Rats with Heart Failure
Abstract INTRODUCTION: Enhanced respiratory muscle strength in patients with heart failure positively alters the clinical trajectory of heart failure. In an experimental model, respiratory muscle training in rats with heart failure has been shown to improve cardiopulmonary function through mechanisms yet to be entirely elucidated. OBJECTIVE: The present r

20. Effect of different anesthetic agents on left ventricular systolic function assessed by echocardiography in hamsters
Determination of left ventricular ejection fraction (LVEF) using in vivo imaging is the cardiac functional parameter most frequently employed in preclinical research. However, there is considerable conflict regarding the effects of anesthetic agents on LVEF. This study aimed at assessing the effects of various anesthetic agents on LVEF in hamsters using tran

21. Cardiac rehabilitation program in patients with Chagas heart failure: a single-arm pilot study
Abstract: INTRODUCTION: The benefit of a cardiac rehabilitation (CR) program for patients with Chagas heart failure (CHF) remains unclear. Therefore, we aimed to investigate the effects of CR for CHF patients. METHODS: A single-arm pilot study, including 12 patients with CHF, was performed. Patients participated in an 8-month physical exercise interventi

22. Intramyocardial implantation of differentiated rat bone marrow mesenchymal stem cells enhanced by TGF-β1 improves cardiac function in heart failure rats
The present study tested the hypotheses that i) transforming growth factor beta 1 (TGF-β1) enhances differentiation of rat bone marrow mesenchymal stem cells (MSCs) towards the cardiomyogenic phenotype and ii) intramyocardial implantation of the TGF-β1-treated MSCs improves cardiac function in heart failure rats. MSCs were treated with different concentrat

23. Duration of Systole and Diastole for Hydrodynamic Testing of Prosthetic Heart Valves: Comparison Between ISO 5840 Standards and in vivo Studies
Abstract Objective: To complement the ISO 5840 standards concerning the duration of left ventricular systole and diastole as a function of changes in heart rates according to in vivo studies from the physiologic literature review. Methods: The systolic and diastolic durations from three in vivo studies were compared with the durations of systole proposed b

24. Assessment of the left ventricular function in normotensive prediabetics: a tissue Doppler echocardiography study
ABSTRACT Objective Several studies have shown that left ventricular (LV) dysfunction is increased in individuals with diabetes. However, there are scarce data about LV function in prediabetics. This study assessed the early changes in LV diastolic and systolic myocardial function in normotensive prediabetics using tissue Doppler echocardiography (TDE). Su
