normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background : supervised exercise-based cardiac rehabilitation programs (crp) have been suggested to all patients, especially after myocardial infarction. however, the effects of cardiac rehabilitation on systolic function are controversial. the aim of this study was to examine the effects of an 8-week cardiac rehabilitatio...

BACKGROUND We examined the relationships of left ventricular (LV) contractile state with LV geometry and hypertrophy in patients with aortic valve disease, and investigated the reversibility of LV hypertrophy and contractility following aortic valve replacement. METHODS Preoperative data from quantitative cineangiography and pressure measurements in 132 patients with chronic aortic valve dise...

Left ventricular (LV) hypertrophy, a marker for adverse cardiovascular events, is more common in blacks than in non-Hispanic whites. Mechanisms leading to LV hypertrophy and mediating its clinical sequelae in blacks are not fully understood. We investigated the associations of 39 candidate biomarkers in distinct biological pathways with LV mass and geometry in blacks. Participants included 1193...

Detailed echocardiographic evaluation was performed on sixty-four normal persons without any cardiovascular risk factor and clinic blood pressure of 120/80 mm of Hg or less with an aim to find, if there are subclinical echocardiographic changes even in this population. There was significant positive linear correlation between mean arterial pressure and LV mass index. On dividing the patients ac...

BACKGROUND Data on the prognostic value of echocardiographic left ventricular (LV) hypertrophy (LVH) as defined by LV wall thickness rather than LV mass estimate are scarce and not univocal. Thus, we investigated the value of LV mass index, wall thickness, and relative wall thickness (RWT) in predicting cardiovascular events in the PAMELA population. METHODS At entry 1,716 subjects underwent ...

Background: Associations between childhood vitamin K consumption and cardiac structure and function have not been investigated.Objective: We determined associations between phylloquinone (vitamin K-1) intake and left ventricular (LV) structure and function in adolescents.Methods: We assessed diet with three to seven 24-h recalls and physical activity (PA) by accelerometry in 766 adolescents (ag...

OBJECTIVE To assess left ventricular (LV) strain and displacement and their relations to LV geometry in patients with aortic stenosis (AS). DESIGN Cross-sectional echocardiographic study in patients with AS. Peak circumferential, radial and longitudinal strain, and radial, longitudinal and transverse displacement were measured by 2D speckle tracking. Severity of AS was assessed from energy lo...

BACKGROUND Information is limited on the longitudinal tracking of left ventricular (LV) mass over the adult life course and the determinants of such change. METHODS AND RESULTS We used multilevel modeling to evaluate the correlates of LV mass prospectively over a 16-year period in 4217 Framingham study participants (mean age 45 years, 53% women) using up to 4 serial routine echocardiographic ...

This study inquired the relationship between serum N-terminal pro-brain natriuretic peptide (NT-proBNP) levels and left ventricular (LV) dysfunction and extracellular water in continuous ambulatory peritoneal dialysis (CAPD) patients. We conducted a cross-sectional study of 30 CAPD patients. Each patient was admitted to the department of internal medicine, Chosun University Hospital between Feb...

BACKGROUND Systemic lupus erythematosus (SLE) is associated with premature atherosclerosis and vascular stiffening. Whether SLE alters left ventricular (LV) structure and function in the absence of valvular and clinical coronary artery disease is unknown. METHODS AND RESULTS SLE patients without clinical or echocardiographic evidence of valvular or coronary disease were age and gender matched...
