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...

Impact of a High-Intensity Training on Ventricular Function in Rats After Acute Myocardial Infarction

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Physical exercise should be part of the treatment of post-acute myocardial infarction (AMI) patients. Objective: To evaluate the effects of two training prescription models (continuous x interval) and its impact on ventricular function in rats after AMI with normal ventricular func...

Heart Rate and its Variability Assessed by Spectral Analysis in Elderly Subjects with Orthostatic Hypotension: A Case-Control Study

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: The prevalence of orthostatic hypotension (OH) increases with age and is associated with changes in autonomic regulation of blood pressure (BP) and heart rate (HR). Objective: to assess HR and HR variability (HRV) in elderly subjects with OH and determine OH predictors. Methods: a...

Is Lipid Accumulation Product Associated with an Atherogenic Lipoprotein Profile in Brazilian Subjects?

Arq. bras. cardiol; 110 (4), 2018
Abstract Background: Lipid accumulation product (LAP), a simple and low-cost tool, is a novel biomarker of central lipid accumulation and represents a potential surrogate marker for atherogenic lipoprotein profile. However, its association with lipoprotein subfractions has not been described in the lite...

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...

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...

Niveles de hormonas tiroideas en recién nacidos muy prematuros y prematuros extremos

Rev. chil. pediatr; 89 (2), 2018
INTRODUCCIÓN: La función tiroidea del prematuro se ve alterada por la relativa inmadurez del eje hipotálamo-hipófisis-tiroides, junto a otros factores como la incidencia de enfermedades o el uso de algunos fármacos. Actualmente existe controversia sobre los niveles normales de tiroxina libre (T4L) ...

Methods: The study included 12 subjects with Wilson's disease with neurol...

Circulating levels of mannose-binding lectin (MBL) in age-related macular degeneration

Arq. bras. oftalmol; 81 (2), 2018
ABSTRACT Purpose: To assess whether the serum levels of mannose-binding lectin of the lectin complement pathway are associated with age-related macular degeneration. Methods: Patients with age-related macular degeneration and age-matched controls underwent full ophthalmologic examination and optical co...
