Filter by:Study population: 1) mutation carriers without the hypertrophic phenotype (pre-clinical Hypertrophic Cardiomyopathy (HCM)) and in 2) patients with clinically overt HCM (clinical HCM). Hypothesis: Cardiac troponin release after exercise can be demonstrated in both clinical and pre-clinical HCM patients.
The purpose of the sudy is to conduct a small study to gather the preliminary data for future lage scale clinical studies that will be designed test the potential beneficial effect of over-the counter study anti-oxidant drug called N-acetylcysteine (NAC) in patients with a heart muscle condition called Hypertrophic Cardiomyopathy (HCM). The present study is a pilot feasibility study, the investigators want to find out whether the investigators can recruit and retain patients with HCM in the study and whether these patients can tolerate this drug and can stay on one year. Likewise, the investigators want to find out any potential side effects that this drug might have and estimate whether it has any beneficial effects.
Principles of motor control suggest that breast hypertrophy can lead to sensoriomotor alterations and impairment in body balance due to postural misalignment. The investigators conducted this study to evaluate the postural control with different sensorial information condition in women with breast hypertrophy.
Left ventricular non-compaction (LVNC) is a rare cardiomyopathy characterized by numerous excessively prominent left ventricular (LV) trabeculation and deep intertrabecular recesses communicating with the ventricular cavity and severely altering myocardial structure. Although most authors assume a developmental arrest in embryogenesis as the underlying pathology, the mechanisms of LVNC are not fully understood yet. Several gene mutations have been identified to be linked with LVNC and an autosomal dominant inheritance pattern is frequent To date the most commonly used imaging tool for diagnosing LVNC is echocardiography applying the criteria established by Jenni and coauthors However, qualitative parameters to differentiate normal compaction of the myocardium in healthy subjects from LVNC or from other cardiomyopathies like dilative cardiomyopathy (DCM) or hypertrophic cardiomyopathy (HCM) may fail due to highly variable LV trabeculation. Therefore, absolute quantification should be performed. Cardiac magnetic resonance (CMR) has been reported as a promising imaging modality to characterize patients with LVNC as it provides both a high spatial resolution and a good contrast between trabeculation and blood pool Jacquier et al. recently described a value of trabeculated LV myocardial mass above 20% of the global mass of the LV to be highly sensitive and specific for LVNC However, in their approach, a substantial degree of the LV cavity was included into calculated trabecular LV mass and led to systemic overestimation of the latter. Furthermore, the role and prognostic value of myocardial scarring as assessed by delayed enhancement (DE) CMR was not evaluated. The aim of the retrospective study was to establish revised and extended CMR criteria to distinguish LVNC from DCM, HCM and a group of healthy controls and to improve the assessment of trabeculated mass by excluding intertrabecular blood pool.
Unfavorably high sodium intakes remain prevalent around the world. A negative sodium gradient in hemodialysis treatment results in absolute sodium removal via diffusive transport of sodium from the blood to the dialysate, and it may be a potentially useful tool to improve sodium loading due to excess dietary sodium intake. The purpose of this study is to determine whether a in small negative sodium gradient could improve blood pressure level, arterial stiffness and left ventricular hypertrophy in hypertensive hemodialysis patients, who had been achieving and maintaining their dry weight assessed by bioimpedance spectroscopy.
Objective The objective of the study is to assess the structural and functional cardiac effects of treatment with losartan in patients with hypertrophic cardiomyopathy (HCM). Design The study is a randomized, placebo‐controlled, double‐blinded trial. The follow‐up period is 12 months. 130 patients with HCM will be included in predefined subgroups. Genotype positive relatives with borderline hypertrophy (> 13 mm) will also be included. Data on individuals with borderline hypertrophy will be analysed separately from the rest of the cohort. Primary outcome Ventricular hypertrophy assessed as left ventricular mass and maximal wall thickness.
The study hypothesis is stress-related regional tissue dynamics is related to left ventricular outflow tract blood flow.
More than 1 million people worldwide wear soft contact lenses for refractive error correction. However, severe sight threatening complications due to contact lens wear such as contact lens-related microbial keratitis (CLMK) are about 1 per 2500 persons per year. The rate of infection increases drastically to 1 per 500 person per year if lenses were worn overnight. Recently, color tinted cosmetic soft contact lenses, which are essentially soft contact lenses with a color tinted annular ring, are gaining increasing popularity especially among the younger and Asian population desiring a change in iris color or the doll-eyed look. However, studies on the effect of these lenses on the ocular surface have been scarce. Recently, a report of 12 cases of lens-related microbial keratitis due to wear of the color tinted lenses have been reported. Others reported of decreased contrast sensitivity, increased higher order aberrations, and temporary changes in corneal topography due to color tinted lens wear. Nevertheless, comprehensive and prospective study has not yet been done. Thus, the purpose of this study is to conduct a prospective observational study to determine the influence of color tinted cosmetic contact lens wear both on visual performance and ocular surface alterations.
Systemic RV hypertrophy and impaired systolic function occur after atrial switch (AS) in d-transposition of the great arteries (d-TGA). Echocardiography has limitation in the assessment of the right ventricle (RV). In this study the investigators sought to evaluate systemic RV myocardial mass and function after AS for d-TGA and to analyze the role of excessive hypertrophy for ventricular function under special consideration of the interventricular septal (IVS) movement.
The study hypothesis: Valsartan as an angiotensin II receptor blocker treatment has beneficial effects on both midwall mechanics and myocardial functions in hypertensive patients with Left ventricular hypertrophy.
