Hipertrofia ventricular izquierda con patrón de strain característico

Rev. chil. cardiol; 36 (3), 2017
Abstracts: A 68 year-old male, with no past medical history, presented progressive shortness of breath on exertion and leg edema during the previous year. Trans-thoracic echocardiography depicted; severe left ventricular hypertrophy with mild systolic dysfunction (LVEF 50% biplane Simpson's method), seve...

Reproducibility and Reliability Of QTc and QTcd Measurements and Their Relationships with Left Ventricular Hypertrophy in Hemodialysis Patients

Arq. bras. cardiol; 109 (3), 2017
Abstract Background: Left ventricular hypertrophy (LVH) is very common in hemodialysis patients and an independent risk factor for mortality in this population. The myocardial remodeling underlying the LVH can affect ventricular repolarization causing abnormalities in QT interval. Objective: to evaluat...

Comparison of Electrocardiographic Criteria for Identifying Left Ventricular Hypertrophy in Athletes from Different Sports Modalities

Clinics; 72 (6), 2017
OBJECTIVES: In athletes, isolated electrocardiogram high voltage criteria are widely used to evaluate left ventricular hypertrophy, but positive findings are thought to represent normal electrocardiogram alterations. However, which electrocardiogram criterion can best detect left ventricular hypertrophy ...

Compromiso cardiovascular en pacientes pediátricos en diálisis peritoneal crónica

Rev. chil. pediatr; 88 (2), 2017
La diálisis peritoneal (DP) es la terapia de reemplazo renal más usada en niños portadores de enfermedad renal crónica terminal. La enfermedad cardiovascular es la principal causa de mortalidad en estos pacientes. OBJETIVO: Caracterizar pacientes pediátricos en DP crónica desde el punto de vista ca...

MCP-1 Levels are Associated with Cardiac Remodeling but not with Resistant Hypertension

Arq. bras. cardiol; 108 (4), 2017
Abstract Background: Hypertension is a chronic, low-grade inflammation process associated with the release of cytokines and development of target organ damage. Deregulated monocyte chemoattractant protein-1 (MCP-1) levels have been associated with high blood pressure and cardiovascular complications; ho...

Electrocardiogram Performance in the Diagnosis of Left Ventricular Hypertrophy in Hypertensive Patients With Left Bundle Branch Block

Arq. bras. cardiol; 108 (1), 2017
Abstract Background: Left ventricular hypertrophy (LVH) is an important risk factor for cardiovascular events, and its detection usually begins with an electrocardiogram (ECG). Objective: To evaluate the impact of complete left bundle branch block (CLBBB) in hypertensive patients in the diagnostic perf...

Importance of SERCA2a on early isolated diastolic dysfunction induced by supravalvular aortic stenosis in rats

Braz. j. med. biol. res; 50 (5), 2017
Cardiac remodeling is defined as changes in shape and function of the heart in response to aggression (pressure overload). The sarcoplasmic reticulum calcium ATPase cardiac isoform 2a (SERCA2a) is a known factor that influences function. A wide spectrum of studies report a decrease in SERCA2a in heart fa...

Resistance training attenuates salt overload-induced cardiac remodeling and diastolic dysfunction in normotensive rats

Braz. j. med. biol. res; 50 (9), 2017
Elevated salt intake induces changes in the extracellular matrix collagen, leading to myocardial stiffness and impaired relaxation. Resistance training (RT) has been used as a remarkably successful strategy in the treatment of heart disease. Therefore, the aim of this study was to investigate the effects...
