BACKGROUND The prognostic importance of left ventricular (LV) mass in nonsevere asymptomatic aortic stenosis has not been documented in a large prospective study. METHODS AND RESULTS Cox regression analysis was used to assess the impact of echocardiographic LV mass on rate of major cardiovascular events in 1656 patients (mean age, 67 years; 39.6% women) with mild-to-moderate asymptomatic aort...

conclusions silent ventricular systolic dysfunction was more common in the patients with sle than in the control group. newer echocardiographic techniques such as two-dimensional ste provide an earlier chance for the detection of subclinical lv systolic dysfunction. our findings were independent of the traditional risk factors. results the mean duration of sle was 5.5 ± 3.4 years in our patient...

AIMS To examine relationships between cardiac troponin T (cTnT) and parameters of left ventricular (LV) structure and function in patients with acute destabilized heart failure (HF) with preserved LV ejection fraction. METHODS AND RESULTS In 44 patients with acute heart failure (HF) with preserved left ventricular (LV) ejection fraction, parameters of LV structure and function were assessed v...

This study was undertaken to assess both the relation between echocardiographic measurement of left ventricular (LV) mass and commonly used electrocardiographic criteria for LV hypertrophy and the effect of the distance from the center of LV mass to the anterior chest wall on precordial voltage. Echocardiograms and standard 12-lead electrocardiograms were obtained on 100 persons, ages 3 to 79. ...

BACKGROUND Data regarding the familial aggregation of left ventricular (LV) geometry and its relations to parental heart failure (HF) are limited. METHODS AND RESULTS We evaluated concordance of LV geometry within 1093 nuclear families in 5758 participants of the original (parents) (n=2351) and offspring (n=3407) cohorts of the Framingham Heart Study undergoing routine echocardiography in mid...

Echocardiograms were obtained on 27 adults with electrocardiographic criteria of left ventricular hypertrophy (LVH) to determine how echocardiograms might best identify LVH. Both the left ventricular (LV) posterior wall thickness and interventricular septal thickness were found by echocardiography to be increased (greater than or equal to 12 mm) in only 13 of 27 patients (48%) with LVH. The LV ...

After the 16th hemodialysis session, LV mass index decreased by 15% (p=0.01), and LA volume decreased by 40.1% (p=0.01). The LV ejection fraction increased by 4.4% units overall (p=0.67). The overall E/Ea ratio decreased by 23.3% (p=0.07). The improvements in LV structure and function were significant in those with initially abnormal values. The rate of echocardiographic abnormalities in this s...

BACKGROUND Coronary artery calcium (CAC), carotid intima-media thickness, and left ventricular (LV) mass and geometry offer the potential to characterize incident cardiovascular disease (CVD) risk in clinically asymptomatic individuals. The objective of the study was to compare these cardiovascular imaging measures for their overall and sex-specific ability to predict CVD. METHODS AND RESULTS...

AIM The aim of the present study was to analyze the relationship between epicardial adipose tissue thickness (EATT) and echocardiographic parameters, such as carotid intima-media thickness (cIMT), myocardial performance index (MPI), left ventricular (LV) systolic and diastolic function, and LV mass index in adolescents with obesity. PATIENTS AND METHODS One hundred and thirty eight obese adol...

BACKGROUND While mammalian heart size maintains constant proportion to whole body size, scaling of left ventricular (LV) function parameters shows a more complex scaling pattern. We used 2-D speckle tracking strain imaging to determine whether LV myocardial strains and strain rates scale to heart size. METHODS We studied 18 mice, 15 rats, 6 rabbits, 12 dogs and 20 human volunteers by 2-D echo...
