The development of left ventricular hypertrophy in patients with heart disease often has far-reaching clinical implications with respect to overall morbidity and mortality. Approaches used to assess left ventricular mass include electrocardiography, echocardiography, contrast ventriculography, single photon-emission tomography, and conventional computed tomography. However, all of these modalit...

An increase in left ventricular mass represents a compensatory response of hypertensive heart to augmented loading conditions. The concept of inappropriate mass has been proposed to define an increase in left ventricular mass higher than needed to compensate for increased workload. To assess whether inappropriate left ventricular mass is associated with more severe impairment of coronary vasodi...

BACKGROUND AND OBJECTIVES Higher left ventricular volume is associated with death in patients with ESRD. This work investigated the effects of frequent hemodialysis on ventricular volumes and left ventricular remodeling. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The Frequent Hemodialysis Network daily trial randomized 245 patients to 12 months of six times per week versus three times per ...

Left ventricular hypertrophy is an independent cardiovascular risk factor. In hypertensives, the pattern of hypertrophy is influenced by central haemodynamic characteristics. Central haemodynamics may also determine physiological differences in left ventricular structure and predispose to particular responses of the left ventricle to pathological increases in load. M-mode echocardiography was u...

background: the prevalence of patients with severe left ventricular dysfunction (lvd) referred for coronary artery bypass grafting (cabg) is increasing. preoperative lvd is an established risk factor for early and late mortality after revascularization. the aim of the present study was to assess the early outcome of patients with severe lvd undergoing cabg. methods: between december 2012 and no...

introduction: left ventricular ejection fraction (lvef) is considered to be the single most important prognostic factor in patients with previous myocardial infarction. lvef is not improved in all patients after coronary artery bypass grafting (cabg). this study aimed to assess the possibility of prediction of lvef changes after cabg using myocardial perfusion gated signle photon emission compu...

hypertonic saline solution can absorb part of the intracellular fluid volume into the extracellular space. the effects of this solution on the cardiovascular system are increased coronary flow and increased left ventricular contraction, without sympathetic system activation. this study was designed to assess the effects of hypertonic saline solution in open heart surgery and to compare it with ...

Left ventricular mass, derived from echocardiographic measurement of left ventricular wall volume, was compared with simple vectorcardiographic and electrocardiographic voltage measurements in 36 patients with left ventricular enlargement and 7 normal subjects. Left ventricular wall volume was obtained by subtracting the volume of the ventricular cavity, calculated as the cube of the ultrasound...

background: it has been well documented that left ventricular hypertrophy (lvh) is an independent factor for cardiac death in children. the epidemiologic information reveals that there is a very high prevalence of lvh in children with chronic renal failure (crf). the purpose of this study was to evaluate the existence of left ventricular hypertrophy, its severity and other cardiac abnormalities...

OBJECTIVES We studied whether left ventricular mass in athletes associates with polymorphisms in genes encoding components of the renin-angiotensin system. BACKGROUND Adaptive left ventricular hypertrophy is a feature of the athlete's heart. However, similarly training athletes develop left ventricular mass to a different extent, suggesting that genetic factors may modulate heart size. METH...
