AIMS Myocardial involvement in Friedreich's ataxia (FRDA) is characterized by iron deposits, diffuse fibrosis, and focal necrosis. We hypothesized that subclinical left ventricular (LV) dysfunction may occur in 'FRDA patients who have normal LV ejection fraction (LVEF) and mass. METHODS AND RESULTS Twenty patients homozygous for the GAA expansion in the frataxin gene (mean age: 35 ± 16 years)...
Polycystic ovary syndrome (PCOS) is characterized by hormonal and metabolic abnormalities and is thought to increase a risk for cardiovascular diseases. In this study we use speckle tracking echocardiography (STE) to evaluate left ventricular (LV) dysfunction in the early period of the disease. We enrolled 31 patients with PCOS and 32 healthy volunteers as a control group. The participants' age...
With aging, structural and functional changes occur in the myocardium without obvious impairment of systolic LV function. Transmural differences in myocardial vulnerability for these changes may result in increase of transmural inhomogeneity in contractile myofiber function. Subendocardial fibrosis and impairment of subendocardial perfusion due to hypertension might change the transmural distri...
AIMS Myocardial involvement is associated with poor prognosis in patients with systemic sclerosis (SSc). Two-dimensional speckle-tracking echocardiography (STE) is a powerful novel modality for the assessment of subclinical cardiac left ventricular (LV) dysfunction that, so far, has not been investigated in SSc patients. The aim of this study was to evaluate deformation analyses derived from ST...
With aging, structural and functional changes occur in the myocardium without obvious impairment of systolic left ventricular (LV) function. Transmural differences in myocardial vulnerability for these changes may result in increase of transmural inhomogeneity in contractile myofiber function. Subendocardial fibrosis and impairment of subendocardial perfusion due to hypertension might change th...
Increased left ventricular (LV) mass in children with chronic renal insufficiency (CRI) might be adaptive to sustain myocardial performance in the presence of increased loading conditions. It was hypothesized that in children with CRI, LV systolic function is impaired despite increased LV mass (LVM). Standard echocardiograms were obtained in 130 predialysis children who were aged 3 to 18 yr (59...
OBJECTIVE We aimed to investigate the association of diffuse myocardial fibrosis by cardiac magnetic resonance (CMR) T1 with complex ventricular arrhythmia (ComVA) in mitral valve prolapse (MVP). METHODS A retrospective analysis was performed on 41 consecutive patients with MVP referred for CMR between 2006 and 2011, and 31 healthy controls. Arrhythmia analysis was available in 23 patients wi...
OBJECTIVES To examine whether individuals with low short-term risk of coronary heart disease but high lifetime predicted risk of cardiovascular disease (CVD) have greater prevalence of left ventricular (LV) hypertrophy and increased aortic wall thickness (AWT) than those with low short-term and low lifetime risk. BACKGROUND Lifetime risk prediction can be used for stratifying individuals youn...
We examined the association between urine albumin excretion (UAE) and common and internal carotid artery intima-media thickness (IMT), end-diastolic left ventricular (LV) mass, and coronary artery calcification (CAC) scores using data from the Multi-Ethnic Study of Atherosclerosis (MESA), a population-based study of 6814 adults aged 45 to 85 years without clinical cardiovascular disease (CVD). ...
BACKGROUND Childhood cancer survivors (CCSs) have an increased risk of morbidity and mortality. We evaluated the prevalence and determinants of left ventricular (LV) dysfunction in a large cohort of long-term CCSs treated with different potentially cardiotoxic therapies. METHODS The study cohort consisted of all adult 5-year CCSs who were treated with potentially cardiotoxic therapies and who...
