Background: Atrial electromechanical delay (EMD) is used to predict atrial fibrillation, measured by echocardiography. Objectives: The aim of this study was to assess atrial EMD and mechanical function after anthracycline-containing chemotherapy. Methods: Fifty-three patients with breast cancer (48 ± 8 years old) who received 240 mg/m2of Adriamycin, 2400 mg/m2 of cyclophosphamide, and 960 mg/m2 of paclitaxel were included in this retrospective study, as were 42 healthy subjects (47 ± 9 years old)...

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia seen in adults. Atrial stunning is defined as the temporary mechanical dysfunction of the atrial appendage developing after AF has returned to sinus rhythm (SR). OBJECTIVES: We aimed to evaluate atrial contractile functions by strain and strain rate in patients with AF, following pharmacological and electrical cardioversion and to compare it with conventional methods. METHODS: This study included 41 patients with persistent AF and 35 age-matched control cases with SR...

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, with an estimated prevalence of 1-2% in North America and Europe. The increased prevalence of AF in Latin America is associated with an ageing general population, along with poor control of key risk factors, including hypertension. As a result, stroke prevalence and associated mortality have increased dramatically in the region. Therefore, the need for effective anticoagulation strategies in Latin America is clear. The aim of this review is to provide a contemporary overview of anticoagulants for stroke prevention...

BACKGROUND: The outcome of Chagas disease patients after receiving implantable cardioverter defibrillator (ICD) is still controversial. OBJECTIVE: To compare clinical outcomes after ICD implantation in patients with chronic Chagas cardiomyopathy (CCC) and ischemic heart disease (IHD). METHODS: Prospective study of a population of 153 patients receiving ICD (65 with CCC and 88 with IHD). The devices were implanted between 2003 and 2011. Survival rates and event-free survival were compared...

BACKGROUND: Stress echocardiography is well validated for diagnosis and risk stratification of coronary artery disease. Exercise stress echocardiography (ESE) has been shown to be the most physiological among the modalities of stress, but its safety is not well established. OBJECTIVE: To study the complications related to ESE and clinical and echocardiographic variables most commonly associated with their occurrence. METHODS: Cross-sectional study consisting of 10250 patients submitted to ESE for convenience, from January 2000 to June 2014...

OBJECTIVE: To determine the clinical and construct validity of the nursing diagnosis "decreased cardiac output" (DCO) in patients with chronic heart failure. METHODS: Cross-sectional study. RESULTS: A total of 200 people were studied. The defining characteristics with the highest prevalence were as follows: arrhythmia (62.5%) and fatigue (61.5%). Adjustment measures such as infit and outfit were maintained between 0.50 and 1.56 and the total variance explained by the measures was 29...

BACKGROUND: Cardiovascular urgencies are frequent reasons for seeking medical care. Prompt and accurate medical diagnosis is critical to reduce the morbidity and mortality of these conditions. OBJECTIVE: To evaluate the use of a pocket-size echocardiography in addition to clinical history and physical exam in a tertiary medical emergency care. METHODS: One hundred adult patients without known cardiac or lung diseases who sought emergency care with cardiac complaints were included...

Background: The QRS-T angle correlates with prognosis in patients with heart failure and coronary artery disease, reflected by an increase in mortality proportional to an increase in the difference between the axes of the QRS complex and T wave in the frontal plane. The value of this correlation in patients with Chagas heart disease is currently unknown. Objective: Determine the correlation of the QRS-T angle and the risk of induction of ventricular tachycardia / ventricular fibrillation (VT / VF) during electrophysiological study (EPS) in patients with Chagas disease...

Adenosine released during ischemia and hypoxia can induce ventricular arrhythmias. This phenomenon is also observed in Chagas disease. This study involved pharmacologic analysis of the arrhythmogenic properties of adenosine in healthy Sprague-Dawley rats (n=14) and in rats with chronic Chagas cardiomyopathy (n=14). Electrocardiographic and pharmacologic studies were performed on isolated hearts prepared using the Langendorff method. Adenosine increased ventricular arrhythmias in both groups of animals in a dose-dependent manner: 50% of chagasic rats developed ventricular fibrillation compared with 7...

Ildikó Imre, Zsuzsanna Tóth
During dental rehabilitation of a patient with ICD, an upper telescope retained overdenture with acrylic baseplate and lower cantilever bridges were constructed. In the consultation following the anamnesis and the clinical examination, the cardiologist did not believe antibiotic profilaxis to be necessary, adding that it is advisable to avoid the use of ultrasonic depurator and electrocauter. Nowadays after saving the life the improving of patient's better quality of life is an important aspect. The risk of ICD-implantation is minimal however, not negligible, the patient can pursue a way of life free of limitation...

BACKGROUND: Aiming to define the profile of curative atrial fibrillation (AF) ablation in Brazil, the Brazilian Cardiac Arrhythmia Society [Sociedade Brasileira de Arritmias Cardíacas] (SOBRAC) created the Brazilian Registry of AF Ablation [Registro Brasileiro de Ablação da FA]. OBJECTIVE: To describe the results of this registry. METHODS: A questionnaire was sent to SOBRAC members asking about data on patients submitted to AF ablation between September 2005 and November, 2006...

We report three children with obstructive sleep apnea syndrome, two secondary to pharyngeal obstruction and the third secondary to laryngomalacia. All patients presented important respiratory efforts with inspiratory stridor during sleep, frequent obstructive apneas with important hipoxemia, sweating, and arousal episodes. Two patients suffered excessive daytime sleepiness, behavioral disturbances and development delay, and the third, intelligence in the borderline retardation range, and important heart arritmias (bradycardia with ventricular extrasystoles) during obstructive apneas...
