13. Validation of the angina questionnaire of the oms on the short version using as gold standard the exercise treadmill test and the pharmacological stress echocardiography / Validação do questionário de angina da OMS na sua versão curta utilizando como padrão ouro o teste de esforço e o ecocardiograma sob estresse farmacológico
OBJECTIVE: To assess the validity of the short version of the WHO/Rose angina questionnaire in Portuguese, applied to adults aged 40-74 years, living at Butantã, reference area of the Hospital Universitário - Universidade de São Paulo, in Brazil using exercise treadmill test and pharmacological stress echocardiography as gold standard. To analyze if the a

14. Estudo da perfusão miocárdica e reserva coronariana pela ecocardiografia sob estresse com perfusão em tempo real em pacientes com diabetes melito descompensado e após tratamento / Myocardial perfusion study and coronary flow reserve by real-time utilizing myocardial contrast echocardiography in decompensated diabetic patients after treatment
Background: Diabetes mellitus (DM) is associated with alterations in coronary flow reserve on microvascular circulation. Real-time myocardial contrast echocardiography has proven to be a useful method for non-invasive evaluation of microvascular alterations. The objective of this study was to assess whether the control of diabetes would influence the values

15. 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

16. Prognostic Value of dobutamine and adenosine stress echocardiography associated with real time myocardial perfusion in patients with known or suspected coronary artery disease / Valor prognóstico da ecocardiografia sob estresse pela dobutamina e adenosina associada à perfusão miocárdica em tempo real em pacientes com doença arterial coronariana suspeita ou confirmada
A ecocardiografia com perfusão miocárdica em tempo real (EPMTR) permite análise simultânea da contração segmentar miocárdica e análise qualitativa da perfusão miocárdica (PQL), além da quantificação da reserva de fluxo sanguíneo do miocárdio (FSM). A EPMTR quantitativa tem demonstrado melhorar a acurácia na detecção de doença arterial coro

17. Effect of simvastatin on diastolic disfunction in hypertensive subjects without evidence of left ventricular hypertrophy or coronary heart disease / Efeito da sinvastatina sobre a disfunção diastolica isolada em pacientes com hipertensão arterial sistemica sem hipertrofia cardiaca e sem doença arterial coronariana
Background: Therapy with statins was suggested to improve survival on heart failure with preserved systolic function. This benefit was attributed probably to their pleiotropic effects on co-morbidities like coronary heart disease or left ventricular hypertrophy. Aims: evaluate the impact of the treatment with simvastatin on echocardiografic parameters of dia

18. Valor prognÃstico da ecocardiografia sob estresse com dipiridamol em mulheres com suspeita de isquemia miocÃrdica
Na Ãltima dÃcada, vem aumentando o interesse na busca de um mÃtodo diagnÃstico nÃo invasivo, para detectar doenÃa arterial coronariana (DAC) em mulheres. Apesar dos avanÃos no diagnÃstico e tratamento, esta patologia permanece como principal causa de mortalidade em mulheres, nos paÃses desenvolvidos. O diagnÃstico precoce, assim como a estratifica�

19. Anomalous origin of the left coronary artery from the pulmonary trunk in a 45-year-old woman
We report a rare case of anomalous origin of the left coronary artery from the pulmonary trunk in a 45-year-old woman. The approach and technique used for selective catheterization of an anomalous left coronary artery arising from the pulmonary trunk are described. Six years after diagnosis, echocardiography showed left ventricular disfunction, and surgical

20. Head-to-head comparison of dipyridamole, dobutamine and pacing stress echocardiography for the detection of myocardial ischemia in an animal model of coronary artery stenosis
To compare the sensitivity of dipyridamole, dobutamine and pacing stress echocardiography for the detection of myocardial ischemia we produced a physiologically significant stenosis in the left circumflex artery of 14 open-chest dogs (range: 50 to 89% reduction in luminal diameter). In each study, dobutamine (5 to 40 µg kg-1 min-1 in 3-min stages) and pacin

21. Contribution of Doppler echocardiography to the evaluation of systolic and diastolic function of obese women versus a control group
OBJECTIVE: To study by doppler echocardiography the cardiac systolic and diastolic functions of health, uncomplicated obese subjects. METHODS: Fifty-nine obese women with an average body mass index (BMI) of 35 kg/m² were evaluated and compared with 19 subjects with an average BMI of 23 kg/m² (control group). RESULTS: In the obese group, a clear tendency wa

22. Noninvasive diagnosis of allograft vascular disease after heart transplantation
OBJECTIVE: To determine the predictive values of noninvasive tests for the detection of allograft vascular disease. METHODS: We studied 39 patients with mean ages of 48±13 years and a follow-up period of 86±13 months. The diagnosis of allograft vascular disease was made by cine-coronary arteriography, and it was considered as positive if lesions existed th

23. Dobutamine stress echocardiography in clinical practice with a review of the recent literature.
Stress echocardiography has been developed in recent years as an effective noninvasive test for the detection and assessment of coronary artery disease. This method combines exercise with 2-dimensional echocardiography, which can assess regional and global left ventricular function during stress. Dobutamine infusion, a pharmacologic means of producing cardio

24. Stress echocardiography in heart failure
Echocardiography has the ability to noninvasively explore hemodynamic variables during pharmacologic or exercise stress test in patients with heart failure. In this review, we detail some important potential applications of stress echocardiography in patients with heart failure. In patients with coronary artery disease and chronic LV dysfunction, dobutamine
