Long-term therapy with antihypertensive agents that reduce sympathetic nervous system activity has been demonstrated by echocardiographic measurements to reverse left ventricular hypertrophy. This investigation evaluated the effects of salt depletion obtained by both chlorthalidone (25 mg/day) and severe restriction of salt intake (about 1016 mg Na+/day) on left ventricular mass (LVM) in as sho...

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 Many cardiovascular and noncardiovascular parameters are thought to be determinants of left ventricular mass (LVM). Complicated interactions necessitate the simultaneous measurement and consideration of each to determine their individual and collective impact on LVM. We undertook such a comprehensive study. METHODS AND RESULTS The influence of anthropometry, cardiac size and contra...

OBJECTIVE To asses the values of echocardiographic measurements in normal children without cardiopathy and to build percentile curves, relating them to the body surface (BS, m(2)). METHODS We analyzed M-mode echocardiographic measurements for children between one and 144 months of age. We assessed right ventricular diastolic diameter (RVDd, mm) and left ventricular diastolic diameter (LVDd, m...

BACKGROUND The aims of this study were to estimate the prevalence of left ventricular systolic (LVSD) and diastolic (LVDD) dysfunction, and to test if BNP and urinary albumin excretion rate (AER) are related to LVSD, LVD and left ventricular mass (LVM) in asymptomatic type 2 diabetes patients. METHODS Presence of LVSD, LVDD and LVM, determined with echocardiography, was related to levels of B...

BACKGROUND Hypertensive patients are characterized by development of both left ventricular hypertrophy (LVH) and endothelial dysfunction METHODS AND RESULTS We enrolled 65 never-treated hypertensive patients (36 men and 29 women aged 45.6+/-6.0 years) to assess the possible relationship between echocardiographic left ventricular mass (LVM) and endothelium-dependent vasodilation. Left ventricu...

Abstract Funding Acknowledgements Type of funding sources: Other. Main source(s): I have received a research fellowship grant from the UK based charity Cardiac Risk in Young Objectives We investigated effect long-term exercise and sex on left ventricular (LV) geometry large group female male masters athletes. Background Studies assessing LV athletes are scarce. Methods Different types were iden...

RATIONALE AND OBJECTIVES To assess the performance of automated quantification of left ventricular function and mass based on heart deformation analysis (HDA) in asymptomatic older adults. MATERIALS AND METHODS This study complied with Health Insurance Portability and Accountability Act regulations. Following the approval of the institutional review board, 160 asymptomatic older participants ...

INTRODUCTION We investigated the association between echocardiographic (Echo) left ventricular mass (LVM) indexed to body surface area (LVM/BSA) or height(2.7) (LVM/H(2.7)) and electrocardiographic (ECG) variables in 546 Chinese hypertensives. METHODS The study group was stratified by gender and by BMI into obese (BMI > or =28 kg/m(2)), overweight (BMI > or =24 kg/m(2) and BMI <28 kg/m(2)), a...
