BACKGROUND The Tei index simultaneously evaluates the ventricular systolic and diastolic functions. It has a good correlation with hemodynamic data and has enabled the detection of initial ventricular function alterations of different etiologies. OBJECTIVE To study initial biventricular function alterations in chagasic patients with no apparent heart(More)
The percutaneous closure of ostium secundum (OS) atrial septal defect (ASD) is a well-established procedure and is today considered the treatment of choice due to its good results and low morbidity and mortality. The procedure is routinely performed through the inferior vena cava (IVC). However, this route of access is not always available due to the(More)
OBJECTIVE The objective of this study was to determine the safety and efficacy of renin-angiotensin system (RAS) inhibitors and beta-blockers in chronic Chagas cardiomyopathy. BACKGROUND Chronic Chagas cardiomyopathy causes substantial morbidity and mortality in Latin America. Whether RAS inhibitors and beta-blockers are safe and beneficial has been(More)
We studied systematically, for the first time, the utility of the six-minute walk test (6MWT) in Chagas disease. The walked distance at 6MWT correlated negatively with the increased circulating levels of monocyte chemoattractant protein (MCP-1, r=-0.358, p=0.04) and natriuretic peptide type B (BNP, r=-0.349, p=0.04), as well as positively with ejection(More)
UNLABELLED Cardiomyopathy is the most important manifestation of Chagas' disease. Brain natriuretic peptide (BNP) level and Doppler echocardiographic parameters for diastolic dysfunction have shown correlation with left ventricle (LV) filling pressures. OBJECTIVES The purpose of this study is to compare BNP levels with Doppler echocardiographic parameters(More)
73 regurgitant systolic murmur (III/VI intensity), better audible in the apex. The rest of the physical examination was normal. The electrocardiogram showed a 4mm elevation in the ST segment in the inferior leads. After the implementation of intra-aortic counterpulsation balloon, the patient was referred for immediate hemodynamic study. Coronary angiography(More)
