Remodelamento cardíaco: análise seriada e índices de detecção precoce de disfunção ventricular

January 2010 · Arquivos Brasileiros de Cardiologia

BACKGROUND: Supravalvar aortic stenosis (SVAS) is used to study overload-induced cardiac remodeling (CR). In this model, neither CR behavior since beginning stage nor the best parameters to identify ventricular dysfunction are clearly stated. Objective: 1) Characterizing, early and evolutively, morphological and functional modifications during CR in rats with SVAS and 2) identifying the most ... [Show full abstract] sensitive index for detecting the moment when the diastolic and systolic dysfunction first appeared in the left ventricle (LV). METHODS: Wistar Rats were divided into two groups - control (CG, n=13) and SVAS (SVASG, n=24) - and studied in post-surgical 3rd, 6th, 12th and 18th weeks. Hearts were analyzed by means of an echocardiogram (ECHO). RESULTS: By the end of the experiment, ratios between the LV, right ventricle and atria and the final body weight were increased in the SVASG. The ECHO showed that the left atrium underwent significant remodeling from the 6th on. The percent of endocardial shortening underwent significant drop as of the 12nd week and the percent of, as of the 18th week, in the SVASG. The ratio between E- wave and A-wave (E/A) was higher in CG compared to the SVASG in all events analyzed. CONCLUSIONS: During the remodeling process, the left ventricle of rats with SVAS presented concentric hypertrophy, early diastolic dysfunction and improvement of systolic function, with posterior performance deterioration. Besides this, the study found out the most sensitive echocardiographic indexes for detecting systolic and diastolic dysfunction are, respectively, the ratio E/A and the percent of endocardial shortening.

Alterações ecocardiográficas em pacientes com insuficiência renal crônica em programa de hemodiálise

January 2010 · Arquivos Brasileiros de Cardiologia

Alterações de estrutura e função cardíacas detectadas pela ecocardiografia são comuns em pacientes com doença renal crônica em hemodiálise e predizem um pior prognóstico. Esta revisão aborda recentes evidências da utilidade do método na detecção da disfunção cardíaca clínica e subclínica, estratificação do risco cardiovascular e avaliação das estratégias de intervenção terapêutica.Alteraciones de ... [Show full abstract] estructura y función cardíacas detectadas por ecocardiografía son comunes en pacientes con enfermedad renal crónica en hemodiálisis y predicen un peor pronóstico. Esta revisión aborda recientes evidencias de la utilidad del método en la detección de la disfunción cardíaca clínica y subclínica, estratificación del riesgo cardiovascular y evaluación de las estrategias de intervención terapéutica.Changes in cardiac structure and function detected by echocardiography are common in patients with chronic kidney disease undergoing hemodialysis, and have been recognized as key outcome predictors. This review attempts to summarize recent evidence pointing to the usefulness of the method in the detection of clinical and subclinical cardiac dysfunction, stratification of cardiovascular risk and assessment of intervention strategies.

Alterações ecocardiográficas em doentes asmáticos

May 2008 · Revista Portuguesa de Pneumologia

Introduction: Asthma is a chronic inflammatory disease which has increased during the last 20 years, putting a strain on medical resources, particularly severe forms of the disease. Treatment in such cases is inhaled corticosteroids and beta agonist drugs that can produce a range of side effects. The aim of this study is to identify echocardiograph abnormalities and correlate them with severity ... [Show full abstract] of disease. Methodology: Eight-seven outpatients were selected at the asthma unit of the Gaffrée Guinle University Hospital (HUGG). Each patient underwent spirometry, electrocardiogram (ECG) and echocardiogram (ECO) during the trial within a month maximum. Echocardiograph abnormalities found related to degree of asthma. Statistical analysis was made by nonparametric tests. Results: We found significant differences (p≤ 0.05) for age, disease duration and haemoglobin saturation (SaO2) between the moderate and severe groups. In the sample a high prevalence of tricuspid insufficiency (41.4%) was identified. Conclusions: ECO identified a series of abnormalities that were not always dependent on severity of disease. ECO can identify pulmonary hypertension through calculation of mean pressure of the pulmonary artery.

Alterações ecocardiográficas em cães sob tratamento prolongado com doxorrubicina

June 2005 · Arquivo Brasileiro de Medicina Veterinária e Zootecnia

Avaliou-se a cardiotoxicidade da doxorrubicina utilizando-se sete cães adultos, clinicamente normais, que receberam 30mg/m² de cloridrato de doxorrubicina (Adriblastina®) por via intravenosa, a cada 21 dias, durante 168 dias (grupo A), perfazendo dose cumulativa total de 240mg/m². Em outros sete cães (grupo B) administraram-se 5ml de solução salina 0,9% estéril por via intravenosa, seguindo-se o ... [Show full abstract] esquema de aplicação proposto anteriormente. Os animais foram avaliados, periodicamente, por meio de exames ecocardiográficos em modo-M e bidimensional. Verificou-se aumento (P
