The relation between left ventricular hypertrophy (LVH) and unfavorable cardiovascular prognosis may involve systemic inflammation and endothelial dysfunction/damage. The aim of this study was to investigate in a cross-sectional design the relationships of LVH with C-reactive protein (CRP) levels (a marker of systemic low-grade inflammation) and with microalbuminuria (a marker ...

Electrocardiographically detected left ventricular hypertrophy (LVH) and echocardiographically detected left ventricular hypertrophy are independent predictors of cardiovascular risk, both are defined as cardiac target organ damage in hypertensive patients. However, in clinical practice the preference is given to echocardiography and the discrepant electrocardiographic (ECG) findings are underestimated or even neglected ...

Left ventricular hypertrophy is one of the main risk factors for cardiovascular mortality and morbidity. It has been proposed that hypertrophic stimuli act in great part by increasing the size of cardiomyocytes, and that the latter characteristic is a necessary condition to differentiate left ventricular hypertrophy from other benign forms ...

BACKGROUND: Anderson-Fabry disease is an X-linked glycosphingolipid storage disorder caused by deficient activity of the lysosomal enzyme alpha-galactosidase A. This leads to a progressive accumulation of globotriaosylceramide (Gb(3)) in the lysosomes of cells throughout the body that ultimately results in premature death from renal, cardiac or cerebrovascular complications. Until recently, ...

OBJECTIVE: Previous studies determined the amount of epicardial fat by measuring the right ventricular epicardial fat thickness. However, it is not proven whether this one-dimensional method correlates well with the absolute amount of epicardial fat. In this prospective study, a new cardiovascular magnetic resonance imaging (CMR) method using the three-dimensional ...

OBJECTIVES: The metabolic syndrome (MS) is associated with left ventricular hypertrophy (LVH). Previous evidence has shown that LVH is favoured by low levels of atrial natriuretic peptide (ANP), independently from blood pressure (BP), in hypertension. Although levels of natriuretic peptides are known to be lower in obesity, plasma ANP levels ...

OBJECTIVE: Type-D or "distressed" personality and depression following admission for acute coronary syndrome (ACS) have been associated with poor clinical outcome. The biological pathways underpinning this relationship may include disruption of the hypothalamic-pituitary-adrenocortical (HPA) axis. We therefore assessed cortisol output in patients who had recently suffered from ACS. METHOD: Salivary ...

BACKGROUND: Increased left ventricular mass (LVM) is an independent risk factor for cardiovascular morbidity and mortality, and may be used for risk stratification. Two-dimensional echocardiography, the most commonly used technique for estimation of LVM, uses the third power of the left ventricular internal diameter (LVID) for the calculation. OBJECTIVES: To ...

Supernova 1987A, the first naked-eye supernova observed since Kepler's supernova in 1604, defies a number of theoretical expectations. Its anomalies have long been attributed to a merger between two massive stars that occurred some 20,000 years before the explosion, but so far there has been no conclusive proof that this ...

Observational studies have identified left ventricular hypertrophy (LVH) as a strong, independent risk factor for the development of heart failure (HF), coronary heart disease and stroke. LVH develops in response to hemodynamic overload. Classical conceptualization has it that LVH would start as an adaptive, beneficial response in order to normalize ...

Background: Long-term physical exercise leads to left ventricular morphological adaptations, which vary with the kind of sport and the intensity and extent of the training. Although the echocardiographic changes related to exercise in athletes participating in various sports have been well described, changes associated with football players have been less ...
Marano Giuseppe - - 2007
In response to an increased afterload, the myocardium undergoes a complex adaptation by which wall stress is normalized and cardiac output is maintained. Although the consensus suggests that the increase of the myocardial mass is a necessary adaptive process to accommodate the increased workload, there is growing evidence that hypertrophy ...

Anderson Robert H - - 2007
Of late, it has become fashionable in the surgical literature to describe the ventricular mass as though arranged in the form of a continuous myocardial band, which starts at the aorta and ends at the pulmonary trunk. On the basis of this concept, its supporters have produced revisionist accounts of ...

Left ventricular hypertrophy (LVH), used in this review to denote abnormally increased left ventricular (LV) mass, is an important cardiac trait because of its association with numerous adverse cardiovascular outcomes including myocardial infarction and heart failure. LV mass is typically assessed by noninvasive cardiac imaging (echocardiography or MRI); electrocardiography is ...

A comparison of the data published in anatomy textbooks and anthropological tables does not reveal any change in basic heart dimensions during the period since the beginning of the 20th century to nowadays. However, normal values of many other parameters have changed up to 30% over the same period. These ...

The cardiac extracellular matrix (ECM) maintains the structural and mechanical integrity of the myocardium. We determined the alterations in the composition of the ECM coincident with the transition from compensated left ventricular (LV) hypertrophy (LVH) to symptomatic congestive heart failure (CHF) and the mechanisms underlying such changes. Heart failure was ...
