1. Morbidity of Chagas heart disease in the microregion of Rio Negro, Amazonian Brazil: a case-control study
A case-control study on the morbidity of Chagas heart disease was carried out in the municipality of Barcelos in the microregion of the Rio Negro, state of Amazonas. One hundred and six individuals, who were serologically positive for Trypanosoma cruzi infection, as confirmed by at least two techniques with different principles, were matched according to age

2. Análise dos pacientes submetidos a operação cardíaca para reconstrução ventricular esquerda na Unicamp : estudo retrospectivo / Surgical ventricular restoration at State University of Campinas : a retrospective study
Introduction: Myocardial infarction might result in dilated left ventricle and numerous techniques were described to restore the original left ventricle shape and identify tools for late survival assessment. The aim of this study is to describe our experience with surgical ventricular restoration (SVR) using modified Dor (MD) procedure using a rigid prosthes

3. Regurgitação valvar funcional em insuficiência cardíaca congestiva descompensada: monitoração não-invasiva por bioimpedância cardíaca e ecocardiografia e resposta à terapêutica / Functional valvular incompetence in decompensated heart failure: noninvasive monitoring and response to medical management.
Objective: We hypothesized that functional mitral and tricuspid valvular incompetence (MR and TR, respectively) are reversible causes of reduced cardiac output in decompensated heart failure (DF) that accompanies systolic dysfunction in ischemic or nonischemic cardiomyopathy. Background: DF, defined as signs and symptoms of heart failure at rest, is rooted i

4. Blood pressure measurements taken by patients are similar to home and ambulatory blood pressure measurements
OBJECTIVE: To compare blood pressure measurements taken at home by physicians, nurses, and patients with office blood pressure measurement , ambulatory blood pressure monitoring and home blood pressure measurement. METHODS: A total of 44 patients seen by a home care program were studied. Protocol 1 a) blood pressure was measured by the patient, a physician a

5. Ventricular natriuretic B-type peptide (BNP) after pediatric heart transplantation / Avaliação do peptídeo natriurético tipo B (BNP) após transplante cardíaco pediátrico
INTRODUCTION: The rejection is one of the main causes of mortality after pediatric heart transplant. B natriuretic peptide has been used as a diagnostic method for rejection mainly in adult patients after heart transplantation. OBJECTIVE: To correlate BNP levels collected at the moment of endomyocardial biopsy with rejection, to evaluate BNP as an additional

6. Peptídeo natriurético do tipo B e índices de deformação miocárdica (strain/strain rate) na doença pulmonar obstrutiva crônica estável e exacerbada
Background: There is little information in the literature about possible cardiovascular hemodynamic alterations during acute exacerbations of chronic obstructive pulmonary disease (COPD). The identification of biochemical, neurohormonal or echocardiograph

7. Hemodiluição normovolêmica aguda: estudo experimental comparativo utilizando amido hidroxietílico a 6% ou solução de Ringer lactato / Acute normovolemic hemodilution: comparative evaluation with hydroxyethyl starch and Lactated Ringers
Normovolemic acute hemodilution is a procedure utilized to decrease the needs of blood transfusion during a variety of surgical procedures. Nevertheless, there are few works that evaluate its pulmonary effects as well as hemodynamic changes by means of echocardiography and tonometric evaluation. Methods: 23 anesthetized pigs (weight 46.6 ± 6.0 kg) were inst

8. Efeitos do losartan e espironolactona sobre a estrutura e função do coração de ratos espontaneamente hipertensos
Background: The clinical syndrome of heart failure is the final pathway for myriad diseases that affect the heart, mainly ischemic heart disease and hypertension. Left ventricular hypertrophy is accompanied by a structural remodeling that includes myocyte hypertrophy and interstitial fibrosis. These structural abnormalities related to fibrosis lead to increa

10. Echocardiography and rupture of the heart.
In four patients with rupture of the free wall of the left ventricle, the diagnosis was made at the bedside using a portable cross-sectional echocardiograph; this was confirmed at necropsy in two patients and by paracentesis in the other two. Weak ventricular contractions were seen after each QRS complex of the electrocardiogram, contradicting a widespread b

11. Raised concentration of plasma creatine kinase BB isoenzyme in myelodysplasia.
A 72 year old woman presented with a suspected myocardial infarction. An echocardiograph showed no acute changes but her plasma creatine kinase (CK) activity was increased at 343 U/l (< 175 normal range). The apparent creatine kinase-MB activity by a CK-M subunit immunoinhibition assay was 350 U/l. In view of the discrepancy between the total creatine kinase

12. Rotational excursion of heart in massive pericardial effusion studied by phased-array echocardiography.
We have observed rotational excursion, comprising anteroposterior and right to left movement of the heart, and cardiac twist around the long axis in 2 patients with massive pericardial effusion, using a phased-array echocardiograph recently developed in this country. Sagittal real-time cross-sections showed only the anteroposterior swing motion, but horizont
