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 evaluate the reproducibility and reliability of measurements of corrected QT interval (QTc) and its dispersion (QTcd) and correlate these parameters with LVH in hemodialysis patients...

Objective: To infer the prevalence and variables predictive of isolated nocturnal hypoxemia and obstructive sleep apnea (OSA) in patients with COPD and mild hypoxemia. Methods: This was a cross-sectional study involving clinically stable COPD outpatients with mild hypoxemia (oxygen saturation = 90-94%) at a clinical center specializing in respiratory diseases, located in the city of Goiânia, Brazil. The patients underwent clinical evaluation, spirometry, polysomnography, echocardiography, arterial blood gas analysis, six-minute walk test assessment, and chest X-ray...

Background: Estimative of left ventricular ejection fraction (LVEF) is a major indication for echocardiography. Speckle tracking echocardiography (STE) allows analysis of LV contraction mechanics which includes global longitudinal strain (GLS) and twist/torsion, both the most widely used. Direct comparison of correlations between these novel parameters and LVEF has never been done before. Objective: This study aims to check which one has the highest correlation with LVEF...

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; however, the mechanisms involved are complex and not fully understood. Objective: This study aimed to compare the levels of MCP-1 in patients with resistant (RH) versus mild-to-moderate (HTN) hypertension and their association with the presence or absence of left ventricular hypertrophy (LVH) in all hypertensive subjects...

Background: The ultraportable echocardiogram machine, with relevant portability and easiness in performing diagnoses, when in experienced hands, may contribute to the reliability of preoperative evaluation in noncardiac surgeries. Objectives: To assess cardiac function parameters in patients aged older than 60 years, candidates of elective noncardiac surgeries, classified as ASA1 or ASA 2 according to surgical risk. Methods: A total of 211 patients referred for elective surgeries, without suspicion of previous heart diseases, were included in the study...

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...

REVIEW

Cardiac resynchronization therapy is an established approach for the treatment of patients with heart failure and left ventricular systolic dysfunction. In most centers, these patients are usually evaluated by echocardiography, which allows collecting a number of cardiac anatomical and functional parameters in a non-invasive, repeatable way and without exposure to ionizing radiation. However, over the years, clinical studies have sometimes emphasized and sometimes reduced the role of this method in the setting of cardiac resynchronization therapy for cardiac dyssynchrony evaluation, prognostic stratification of patients, optimization of pacing, and follow-up...

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. Patients with ischemic changes in the electrocardiography or fever were excluded...

Background: Studies have demonstrated the diagnostic accuracy and prognostic value of physical stress echocardiography in coronary artery disease. However, the prediction of mortality and major cardiac events in patients with exercise test positive for myocardial ischemia is limited. Objective: To evaluate the effectiveness of physical stress echocardiography in the prediction of mortality and major cardiac events in patients with exercise test positive for myocardial ischemia. Methods: This is a retrospective cohort in which 866 consecutive patients with exercise test positive for myocardial ischemia, and who underwent physical stress echocardiography were studied...

REVIEW
Cesare de Gregorio, Antonio Vittorio Panno
This review addresses some practical aspects of Doppler echocardiography and how to perform it in outpatients with heart failure, in an attempt to make the diagnostic protocols more effective and less expensive for the national healthcare system. This problem comes from the relevant percentage of redundant echocardiographic exams that are irrelevant for the appropriate clinical management. The most important echocardiographic indices to be used for making diagnosis of left ventricular systolic and/or diastolic dysfunction are also discussed...

Echocardiography is the most commonly used imaging technique in current clinical cardiology practice and is usually performed using a monoplane approach. In recent years new matrix-array transducers have become available that allow the real-time simultaneous display of two or more echocardiographic scanning planes from the same acoustic window. This multiplane approach is particularly interesting as it may reduce, during the examination, the number of probe movements and consequently facilitate image acquisition...

Tricuspid valve (TV) morphology and function evaluation plays a key role in several cardiac diseases, including left-sided valvular diseases and heart failure. However, TV is structurally complex and, differently from aortic and mitral valves, cannot be visualized in a single two-dimensional echocardiographic view, neither transthoracic nor transesophageal (i.e., simultaneous imaging of the three TV leaflets and their attachment to the annulus is not feasible). Conversely, real-time three-dimensional transthoracic echocardiography allows complete visualization of the TV apparatus from multiple views...

The introduction of three-dimensional echocardiography and its evolution from time-consuming and cumbersome off-line reconstruction to real-time volumetric technique (real-time three-dimensional echocardiography) are one of the most significant advances in ultrasound imaging of the heart of the past decade. This imaging modality currently provides realistic views of cardiac valves capable of demonstrating the anatomy of various heart valve diseases in a unique, noninvasive manner. In addition, real-time three-dimensional echocardiography offers completely new views of the valves and surrounding structures, and allows accurate quantification of severity of valve disease...

Several studies have demonstrated the usefulness of B-type natriuretic peptide (BNP) dosage in patients referring for acute dyspnea in the emergency department. BNP is strongly associated not only with the evidence but even with the degree of heart failure, and BNP values are particularly increased in the advanced NYHA classes and in patients with poor prognosis. High BNP levels correlate with echocardiographic indexes of left ventricular and right ventricular systolic dysfunction but even better with diastolic dysfunction and degree of left ventricular filling pressure...
