The impact of ageing and exercise training on cardiac structure and function in healthy females
… controls. The exact nature of left ventricular (LV) remodelling with age is the source of some controversy. Within a cross-sectional design cardiac structure and function was assessed in 124 women and 74 men (18-76 years). Left ventricular mass was maintained across the adult age-span in females …

Cardiovascular disease risk in children : 'pre-clinical' markers and the impact of body composition, physical activity and cardiorespiratory fitness
… atherosclerotic load such as left ventricular (LV) mass, diastolic function and carotid intima-media thickness( cIMT). Further, assessing the association of these markers to other risk factors and then determining the impact of physical activity (PA) interventions is warranted. Initially we …

MATRIX METALLOPROTEINASES AND LEFT VENTRICLE MASS AND FUNCTION
Introduction: Left Ventricle (LV) remodelling is critical pathophysiological process in the development of heart failure. Previous published studies have suggested the pivotal role of matrix metalloproteinases and NT- pro BNP in the pathogenesis of LV remodelling. Our objective was to establish a …

The Etiology of LVH - A Review Of Genetic Predispositions
… reduced ejection fraction, and left ventricular mass (LVM).3 The second putative association tested was whether polymorphisms in the alpha 2A-adrenergic receptor (DraI restriction fragment length protein) and the alpha 2C-adrenergic receptor (Del 322-325) increased the risk of hypertension in …

Quantification of cardiac structure and function using transthoracic echocardiography in term women with HIV
… in the two groups were similar in age, and body mass index. Mean CD4 count was 452 ± 187.8 and duration of therapy was 15.9 ± 22.4 months. Compared with healthy pregnant women, women with HIV have systolic changes exhibited by reductions in left ventricle (LV) septal and right ventricle (RV) …

Redefinition of uraemic cardiomyopathy with cardiac magnetic resonance imaging
… as the presence of left ventricular (LV) abnormalities, including left ventricular hypertrophy (LVH), LV dilatation and LV systolic dysfunction. However, echocardiography makes assumptions regarding LV geometry, which is frequently distorted in patients with ESRD. Furthermore any …

Cardiometabolic risk in 10 to 11 year old children : the impacts of physical activity, cardiorespiratory fitness, body composition and lifestyle education
… 4) the relationships between non- invasive (LV Mass, E/A, E'/A', E/E', trunk fat mass, whole body fat mass) and invasive CM risk markers (CRP, HOMA-IR, adiponectin, TC: HDL-C), and between all risk markers and CRF (V02 peak), time spent sedentary, moderate to vigorous intensity PA (MVPA) and …

Sex Differences in Cardiovascular Adaptations to Chronic Endurance Exercise
… adaptations manifested as increased cardiac mass, higher cardiac function and lower central hemodynamic load (blood pressure, aortic stiffness and wave reflections). However, studies in male marathoners suggest detrimental cardiac remodeling, such that larger cardiac mass is associated with …

The Efficacy Of Prostaglandin Synthase Inhibition On Attenuating Pressure Overload Induced Cardiac Remodeling
… overload and associated Left ventricular (LV) structure and functional changes were measured by pressure-volume admittance catheterization. Human cardiac fibroblasts were used to assess the specific mechanistic pathways associated with prostaglandin D2 (PGD2) mediated fibrotic response. At …

The Effect of Allopurinol on Left Ventricular Mass in Patients with Treated Essential Hypertension
Left ventricular hypertrophy (LVH) confers a high cardiovascular risk independent of blood pressure. It is prevalent in hypertensive patients even when the blood pressure is controlled, and LVH regression has prognostic benefit. Residual risk remains in well controlled hypertension and therefore …

Impact of Dialysis Modality on Left Ventricular Geometry in End Stage Renal Disease Patients
BACKGROUND: Left ventricular hypertrophy (LVH) is an independent risk factor for morbidity and mortality in patients with end stage renal disease (ESRD). This study aimed to evaluate impact of dialysis modality on LV geometry by using echocardiography. METHODS: We retrospectively evaluated change …

High-field Cardiac Magnetic Resonance Imaging in Small Animal Models of Cardiovascular Disease
… Assessment of the left and right ventricular (LV, RV) structural and functional changes concomitant with the aforementioned pathologies is vital, particularly when evaluating the efficacy of a potential cardiac therapy. High-field in vivo cardiac magnetic resonance imaging (CMRI) provides …

Assessment of aortic stenosis using modern non-invasive imaging techniques
… both by progressive narrowing of the valve and the hypertrophic response of the left ventricle. The purpose of this thesis was to study the contribution of inflammation and calcification to valve narrowing using Positron Emission and Computed Tomography (PET/CT) and to investigate the …

Cardiovascular Effects of Metformin on Left Ventricular Hypertrophy in Nondiabetic Patients with Coronary Artery Disease
Left ventricular hypertrophy (LVH) is highly prevalent in patients with coronary artery disease (CAD) irrespective, of blood pressure (BP) and is associated with an increased risk of all-cause mortality and cardiovascular events including myocardial infarction, heart failure, stroke and …

Age and gender differences in risk factor burden, myocardial dysfunction and cardiovascular events in relation to glucose metabolism
… of left ventricular diastolic dysfunction (LVDD), LV mass index (LVMI) and glucometabolic status were studied in echocardiography subcohorts from the two cohort studies (MPP-RES n=1,792; AGES-RS n=841). The MPP-RES cohort was divided into two age groups: middle-aged (57-69 years) and elderly …

The Direct Impact of Trimethelamine-N-Oxide on Cardiac Function
… was measured by liquid chromatography-tandem mass spectrometry (LC/MS/MS) method at the end of the feeding protocol. Echocardiography and electrocardiography (ECG) were performed to assess the overall heart function. The histopathology staining was used to evaluate the cardiac microstructure …

Athletes heart and exercise related sudden cardiac death: Across the age span
… particularly when high-profile athletes are involved. To date, limited evidence for the efficacy of cardiovascular pre-participation screening exists outside of the Italian experience. Furthermore, limited data exists examining the impact of ethnicity on cardiac adaptations to physical training. …
