Milena Novaes Cardoso Curiati, Odilson Marcos Silvestre, Lucas José Tachotti Pires, Sandrigo Mangini, Philippe Vieira Pires, Fabio Antonio Gaiotto, [...]

DOI: 10.1590/S1679-45082013000300003

Objective:To correlate the serum levels of B type natriuretic peptide and the N-terminal fraction of the pro-B type natriuretic peptide, as well as to analyze the influence of age, obesity, renal failure, left ventricle ejection fraction, diastolic dysfunction, and anemia on serum levels of both markers.METHODS:An observational study in which the agreement was compared between these markers in consecutive samples of 138 patients. For the correlation, Pearson’s test was used, and p

DOI: 10.1590/S1679-45082013000300004

Objective:Identify the primary factors that influenced the participant in our cardiovascular rehabilitation program towards missing their therapy sessions, and to correlate those factors with age, cardiovascular risk, and motivation of our population.METHODS:We conducted a retrospective study with 42 patients (69.15±13.93 years) participating in the cardiac rehabilitation program at a general hospital in São Paulo, through the analysis of two scales applied during the initial evaluation: Cardiac Rehabilitation Barriers Scale and scale of the original provision. We used Spearman correlation to […]

Heart rate variability and its relationship with central and general obesity in obese normotensive adolescents

Breno Quintella Farah, Wagner Luiz do Prado, Thiago Ricardo dos Santos Tenório, Raphael Mendes Ritti-Dias

DOI: 10.1590/S1679-45082013000300005

Objective:To analyze the relationship between the heart rate variability parameters and the indicators of central and general obesity in obese normotensive adolescents.METHODS:Seventyfour 13 to 18 year-old obese normotensive adolescents participated in this study. The indicators analyzed for central and general obesity were waist circumference and body mass index, respectively. Heart rate variability was obtained by heart rate monitoring. For this, the adolescents remained in a supine position for 7 minutes with controlled breathing. Parameters were obtained in time domain (standard […]

Electrophysiological characteristics of Chagas disease

Swellen Schuenemann Cedraz, Paulo Christo Coutinho da Silva, Ricardo Katsumi Yendo Minowa, Juliano Furtado de Aragão, Danilo Victor Silva, Carlos Morillo, [...]

DOI: 10.1590/S1679-45082013000300006

Objective:Chagas disease has become a global problem due to changing migration patterns. An electrophysiological study is generally indicated for assessing sinus node function, conduction through the atrioventricular node and His-Purkinje system, in addition to evaluating the mechanisms of arrhythmia. The aim of this study was to describe the characteristics of electrophysiological study findings in patients with Chagas disease.METHODS:A retrospective descriptive study of 115 consecutive patients with Chagas disease undergoing an electrophysiological study over the last three years in a tertiary […]

Robotic surgery in Cardiology: a safe and effective procedure

Robinson Poffo, Alisson Parrilha Toschi, Renato Bastos Pope, Alex Luiz Celullare, Anderson Benício, Claudio Henrique Fischer, [...]

DOI: 10.1590/S1679-45082013000300007

Objective:To evaluate the short and medium-term outcomes of patients undergoing robotic-assisted minimally invasive cardiac surgery.METHODS:From March 2010 to March 2013, 21 patients underwent robotic-assisted cardiac surgery. The procedures performed were: mitral valve repair, mitral valve replacement, surgical correction of atrial fibrillation, surgical correction of atrial septal defect, intracardiac tumor resection, totally endoscopic coronary artery bypass surgery and pericardiectomy.RESULTS:The mean age was 48.39±18.05 years. The mean cardiopulmonary bypass time was 151.7±99.97 minutes, and the mean aortic cross-clamp time was 109.94±81.34 minutes. […]

Relevance of prehypertension as a diagnostic category in asymptomatic adults

Fernando Costa Nary, Raul D. Santos, Antonio Gabriele Laurinavicius, Raquel Dilguerian de Oliveira Conceição, José Antonio Maluf de Carvalho

DOI: 10.1590/S1679-45082013000300008

Objective:To assess the association of prehypertension with metabolic, inflammatory and cardiovascular risk profile in asymptomatic individuals.METHODS:Between 2006 and 2009, 11,011 asymptomatic adults (mean age: 43 years; 22% females), underwent a check-up protocol. They were divided into 3 groups: normotensive group (arterial pressure=120/80mmHg), prehypertensive group (arterial pressure >120/80mmHg and 140/90mmHg or prior diagnosis of hypertension). Each group metabolic and cardiovascular group profile was assessed.RESULTS:The prevalence of normotension, prehypertension and hypertension was 27.9%, 53.9% and 18.2%, respectively. Prehypertensive individuals were older (mean […]

Implementation of an institutional protocol for rational use of blood products and its impact on postoperative of coronary artery bypass graft surgery

Pedro Gabriel Melo de Barros e Silva, Dimas Tadahiro Ikeoka, Viviane Aparecida Fernandes, Nilza Sandra Lasta, Debora Prudencio e Silva, Mariana Yumi Okada, [...]

DOI: 10.1590/S1679-45082013000300009

Objective:Cardiac surgeries are sometimes followed by significant blood loss, and blood transfusions may be necessary. However, indiscriminant use of blood components can result in detrimental effects for the patient. We evaluated the short-term effects of implementation of a protocol for the rational use of blood products in the perioperative period of cardiac surgery.METHODS:Between April and June 2011, an institutional protocol was implemented in a private hospital specializing in cardiology to encourage rational use of blood products, with the consent and […]

Clinical and echocardiographic characteristics associated with the evolution of the ductus arteriosus in the neonate with birth weight lower than 1,500g

Luiza Fortunato Visconti, Samira Saady Morhy, Alice D'Agostini Deutsch, Gláucia Maria Penha Tavares, Tatiana Jardim Mussi Wilberg, Felipe de Souza Rossi

DOI: 10.1590/S1679-45082013000300010

Objective:To identify clinical and echocardiographic parameters associated with the evolution of the ductus arteriosus in neonates with birth weight lower than 1,500g.METHODS:Retrospective study of 119 neonates in which clinical parameters (Prenatal: maternal age, risk of infection and chorioamnionitis, use of corticosteroid, mode of delivery and gestational age. Perinatal: weight, Apgar score, gender and birth weight/gestational age classification; Postnatal: use of surfactant, sepsis, fluid intake, heart murmur, heart rate, precordial movement and pulses, use of diuretics, oxygenation index, desaturation/apnea, ventilatory support, […]
