BACKGROUND Left ventricular hypertrophy (LVH) is identified by left ventricular mass (LVM) normalized by body surface area (BSA) or height (in meters) also raised to allometric powers. The presence of LVH detected by these indices predicts increased cardiovascular (CV) events. Whether different indexations of LVH differ in their ability to predict excess risk is unknown. METHODS A total of 24...

Background It has been suggested that echocardiographically determined left ventricular mass (LVM) is useful in the prediction of hypertension. To examine the relation between LVM and subsequent blood pressure (BP) change, a 6to 8-year follow-up was conducted in adult Japanese men. Methods and Results LVM was determined by M-mode echocardiography using the American Society of Echocardiography f...

BACKGROUND High left ventricular mass (LVM) is an independent predictor of cardiovascular disease and mortality, but information relating LVM in older age to growth in early life is limited. We assessed the relationship of birthweight, height and body mass index (BMI) and overweight across childhood and adolescence with later life left ventricular (LV) structure. METHODS We used data from the...

Cardiac left ventricular hypertrophy (LVH) is commonly associated with hypertension, but its variance is determined for more than 50% by blood pressure-independent genetic factors. Because it constitutes one of the most important risk factors for cardiovascular mortality, we have performed a genome-wide scan of the F2 progeny of crosses between inbred WKY and WKHA rats to detect quantitative tr...

UNLABELLED Background : Exercise-induced arterial hypertension (EIAH) leads to myocardial hypertrophy and is associated with a poor prognosis. EIAH might be related to the "cardiac fatigue" caused by endurance training. The goal of this study was to examine whether there is any relationship between EIAH and left ventricular hypertrophy in Ironman-triathletes. METHODS We used echocardiography ...

BACKGROUND AND PURPOSE Previous studies have demonstrated that echocardiographic left ventricular mass (LVM) is an independent risk factor for stroke in whites. Despite the greater burden of stroke, the echocardiographic predictors of stroke in African Americans remain poorly understood. METHODS This investigation is a retrospective analysis of prospectively collected data from the Jackson, M...

BACKGROUND For diagnosis of significant coronary artery stenosis, the most accurate parameter among the conventional echocardiographic parameters remains unknown. OBJECTIVES To assess the diagnostic efficacy of conventional echocardiographic parameters in the diagnosis of significant coronary artery stenosis and their correlation with the percentage of stenosis considering conventional corona...

In adults, calculation of left ventricular mass (LVM) has been shown to give higher values when based on M-mode measurements obtained by the second-harmonic imaging (SHI) technique than with the older fundamental imaging (FI) technique. No information is available in paediatric subjects. This study, therefore, compares LVM calculated from measurements obtained with SHI and FI in 14 children, ag...

BACKGROUND An increase in left ventricular mass (LVM) is associated with mortality and cardiovascular morbidity in patients with end-stage renal disease. METHODS AND RESULTS The Frequent Hemodialysis Network (FHN) Daily Trial randomized 245 patients to 12 months of 6 times per week daily in-center hemodialysis or conventional hemodialysis; the FHN Nocturnal Trial randomized 87 patients to 12 ...
