Outcomes following coronary artery bypass graft surgery in patients with mild preoperative renal insufficiency

Abstract Introduction: Preoperative renal insufficiency is an independent predictor of mortality after coronary artery bypass graft (CABG) surgery. However, there are few reports aimed to evaluate the impact of mild preoperative renal insufficiency on long-term follow-up outcomes after isolated CABG sur...

Use of doppler ultrasound for saphenous vein mapping to obtain grafts for coronary artery bypass grafting

Abstract Introduction: The great saphenous vein is widely used as a graft in coronary artery bypass grafting surgery. Complications due to saphenous vein harvesting can be minimized when using ultrasonography mapping and marking. Objective: To analyze by clinical trial the use of vascular ultrasonograp...

Association of oscillatory ventilation during cardiopulmonary test to clinical and functional variables of chronic heart failure patients

Abstract Objective: The aim of this study is to characterize the presence of exercise oscillatory ventilation (EOV) and to relate it with other cardiopulmonary exercise test (CET) responses and clinical variables. Methods: Forty-six male patients (age: 53.1±13.6 years old; left ventricular ejection fr...

Influence of Aerobic Training on The Mechanics of Ventricular Contraction After Acute Myocardial Infarction: A Pilot Study

Arq. bras. cardiol; 110 (4), 2018
Abstract The study of myocardial contractility, based on the new anatomical concepts that govern cardiac mechanics, represents a promising strategy of analysis of myocardial adaptations related to physical training in the context of post-infarction. We investigated the influence of aerobic training on ph...

Association of Monocyte Count on Admission with the Angiographic Thrombus Burden in Patients with ST-Segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: The intracoronary high-thrombus burden during the primary percutaneous coronary intervention in patients with ST-elevation myocardial infarction (STEMI) can lead to poor outcomes. Monocytes have been described to play an important role in thrombotic disorders. Objectives: This stud...

Applicability of Longitudinal Strain of Left Ventricle in Unstable Angina

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Unstable angina (UA) is a common cause of hospital admission; risk stratification helps determine strategies for treatment. Objective: To determine the applicability of two-dimensional longitudinal strain (SL2D) for the identification of myocardial ischemia in patients with UA. Me...

Infection in Patients with Decompensated Heart Failure: In-Hospital Mortality and Outcome

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Heart failure (HF) is a syndrome, whose advanced forms have a poor prognosis, which is aggravated by the presence of comorbidities. Objective: We assessed the impact of infection in patients with decompensated HF admitted to a tertiary university-affiliated hospital in the city of ...

Mid-Term Results of Surgical Treatment of Atrial Fibrillation in Valvular Heart Disease Assesed by Speckle Tracking Echocardiography

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Atrial fibrillation frequently affects patients with valvular heart disease. Ablation of atrial fibrillation during valvular surgery is an alternative for restoring sinus rhythm. Objectives: This study aimed to evaluate mid-term results of successful atrial fibrillation surgical ab...

Vimentin and Anti Vimentin Antibodies in Chagas' Disease

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Vimentin is a main structural protein of the cell, a component of intermediate cell filaments and immersed in cytoplasm. Vimentin is mimicked by some bacterial proteins and anti-vimentin antibodies occur in autoimmune cardiac disease, as rheumatic fever. In this work we studied vime...

Comparison of topical and retrobulbar anesthesia in terms of pain experience during silicone oil extraction

Arq. bras. oftalmol; 81 (2), 2018
ABSTRACT Purpose: To compare the use of topical anesthesia and retrobulbar anesthesia during silicone oil removal with a mixed pars plana technique, through evaluating the pain experience of patients. Methods: We selected patients according to their behavior during previous vitreoretinal surgery and op...
