BACKGROUND Ultrasonic backscatter parameters were analyzed in hypertensive patients and divided into groups according to both severity of left ventricular hypertrophy (LVH) (group A: no LVH [n=52]; B: mild to moderate LVH [n=55]; and C: severe LVH [n=10]) and left ventricular geometry (normal geometry [n=44]; concentric remodeling [n=8]; concentric hypertrophy [n=25]; and eccentric hypertrophy ...

Background: Obesity is a risk factor for cardiovascular disease and mortality. Significant weight loss has beneficial effects on left ventricular structure, in particular on regression of left ventricular hypertrophy (LVH). We therefore evaluated the consequences of significant weight loss on left ventricular morphology, hemodynamics and pericardial fat. Methods: We performed volumetric cardiac...

BACKGROUND Long term endurance training is known to increase peak oxygen uptake (VO2peak) and induce morphological changes of the heart such as increased left ventricular mass (LVM). However, the relationship between and the total heart volume (THV), considering both the left and right ventricular dimensions in both males and females, is not completely described. Therefore, the aim of this stud...

OBJECTIVES The purpose of the present study in patients with severe aortic stenosis was to assess the prevalence of absent left ventricular hypertrophy (LVH) (determined according to mass criteria), to identify predictors of absent LVH, and to assess short-term left ventricular adaptation and prognosis after aortic valve replacement. METHODS Left ventricular mass (LVM) was determined by echoc...

OBJECTIVE In this study, the associations between pulmonary artery stiffness (PAS) and aortic stiffness, left ventricular diastolic parameters, and left ventricular mass (LVM) index in moderate to severe obstructive sleep apnea syndrome (OSAS) patients without coexisting disorders were investigated. METHODS A total of 66 non-diabetic, non-hypertensive, and non-smoking volunteers were enrolled...

Growth hormone (GH) can influence left ventricular myocardial growth, structure, and function. The GH secretagogue receptor (GHSR, ghrelin receptor) is known to be involved in GH release and is expressed in the myocardium. We hypothesized that genetic variants within the GHSR are associated with parameters of left ventricular mass (LVM) and geometry. Ten single-nucleotide polymorphisms (SNPs) c...

Cardiovascular disease is increased in individuals with type 1 or type 2 diabetes mellitus (DM). Left ventricular hypertrophy (LVH), which is an ominous prognostic sign and an independent risk factor for cardiac events, is often present in type 2 DM patients. The aim of our cross-sectional study was to evaluate the prevalence of LVH, and risk factors for its development, in normotensive type 2 ...

the present study attempted to compare the structural and functional changes of left heart ventricle in female basketball players of khuzestan superior league (aged between 18 and 29) during regular training and long-term detraining. out of 30 female players, 15 subjects were assigned randomly to regular training group and 15 subjects to long-term detraining group. the structural and functional...

Increased urinary albumin excretion (UAE) has been shown to be associated with increased cardiovascular mortality in patients with type 2 diabetes. This study evaluated whether the association between UAE and cardiovascular mortality in 880 patients with type 2 diabetes was related to an increase in left ventricular mass (LVM). LVM was estimated by electrocardiographic index, namely adjusted Co...

The ability to estimate left ventricular mass (LVM) from the standard 12-lead electrocardiogram (ECG) has been shown to be limited, since there is a considerable variability of the normal 12-lead ECG due to demographic and anthropometric variables. We sought to study LVM, in healthy subjects, and its relationship with QRS duration and established electrocardiographic criteria for left ventricul...
