AIMS The present study aimed to test the capability of real-time three-dimensional echocardiography (RT3DE) in characterizing early abnormalities of left ventricular (LV) structure and function in native, untreated hypertensive patients. METHODS AND RESULTS Thirty-eight newly diagnosed, never-treated hypertensives (H) and 38 healthy controls (C) underwent both standard echo-Doppler and RT3DE ...

BACKGROUND Left ventricular (LV) mass ascertained using echocardiography may enhance risk stratification for sudden cardiac death. The objective of this study was to assess the association between left ventricular mass and the risk of sudden cardiac death in a population-based cohort and determine its incremental value beyond conventional risk predictors. METHODS AND RESULTS Assessment of LV ...

BACKGROUND A biomarker that is of great interest in relation to adverse cardiovascular events is soluble ST2 (sST2), a member of the interleukin family. Considering that metabolic syndrome (MetS) is accompanied by a proinflammatory state, we aimed to assess the relationship between sST2 and left ventricular (LV) structure and function in patients with MetS. METHODS A multicentric, cross-secti...

Purpose: The aim of this study was to determine left ventricular (LV) mass index via echocardiography in end-stage renal disease patients (ESRD) before and after renal transplantation, and its association with one-year survival. Materials and Methods: Forty-seven patients with ESRD who were candidate for renal transplantation were evaluated with echocardiography before and 4 months after the op...

To evaluate the prognostic impact of left ventricular (LV) mass exceeding individual needs to compensate hemodynamic load, the percentage of excess of echocardiographic LV mass in relation to individual ideal value predicted by gender, stroke work, and height (in meter(2.7)) from a reference population was assessed in 1019 white hypertensives (627 women [24% obese] and 392 men [17% obese, P<0.0...

BACKGROUND Left ventricular (LV) hypertrophy has been established as an independent risk factor for cardiovascular disease in adults. Recent research has refined this relationship by determining a cutpoint of 51 g/m(2.7) for LV mass index indicative of increased risk and defining LV geometric patterns that are associated with increased risk. The purpose of this study was to evaluate severe LV h...

BACKGROUND Elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP) is associated with clinically overt heart failure (HF). However, whether it provides additive prognostic information for incident HF beyond traditional risk factors and left ventricular (LV) mass index among multi-ethnic asymptomatic individuals has not yet been determined. We studied the associations of plasma NT-proBNP ...

AIM It was the aim of our study to determine whether myocardial fibrosis influences physiologic or non-physiologic left ventricular (LV) hypertrophy in severe aortic stenosis. METHODS Myocardial fibrosis was evaluated using specimens taken from the ventricular septum in 79 patients submitted to aortic valve replacement because of symptomatic aortic stenosis. Patients were considered to have p...

BACKGROUND/AIMS There are few data on the effects of low hemoglobin levels on the left ventricle (LV) in patients without heart disease. The objective of this study was to document changes in the echocardiographic variables of LV structure and function after the correction of anemia without significant cardiovascular disease. METHODS In total, 34 iron-deficiency anemia patients (35 ± 11 years...

BACKGROUND Increased left ventricular (LV) mass and endothelial dysfunction are important risk factors for cardiovascular mortality and morbidity. However, it is not clear whether endothelial dysfunction is associated with increased LV mass. We tested the hypothesis that impaired flow-mediated vasodilatation (FMD) is associated with increased LV mass in a population-based multiethnic cohort. ...
