Cardiomyopathy is an important and frequently life limiting manifestation of Friedreich's ataxia (FA), the most prevalent form of autosomal recessive ataxia. Left ventricular mass is used as primary outcome measure in recent intervention studies but systematic analyses of FA cardiomyopathy are sparse. To assess cardiac hypertrophy by cardiac magnetic resonance imaging (MRI) in vivo, we assessed...

Introduction: In renal failure patients, cardiovascular complications are a major clinical problem. Objectives: This study aimed to test, the possible association of left ventricular hypertrophy and ejection fraction with plaques of carotid and femoral artery hemodialysis. Patients and Methods: Sixty-one patients, who were on regular hemodialysis were selected. For all patients echocardiography...

The relationships between angiotensin-converting enzyme (ACE) gene insertion (I) / deletion (D) polymorphism and left ventricular hypertrophy induced by hypertension or idiopathic hypertrophic cardiomyopathy have been studied. However, little is known about the association between this polymorphism and left ventricular hypertrophy induced by volume overload. The relationship between left ventri...

The complex problem of left ventricular hypertrophy (LVH) related to systemic arterial hypertension (H) has motivated several experimental, clinical and epidemiological studies. Because LVH is an important predisposing factor for heart failure 1 and because it is physiopathologically related to ischemic heart disease and ventricular arrhythmias, hypertensive left ventricular hypertrophy is an i...

BACKGROUND Stroke is a recognized clinical course of hypertrophic cardiomyopathy. This interesting case showed notable difference on the electrocardiogram of a patient 4 months prior to suffering a stroke and 10 days after suffering a stroke. The pre-stroke electrocardiogram showed atrial fibrillation with a narrow QRS complex, while the post-stroke electrocardiogram showed marked left ventricu...

Children with congenital aortic stenosis have "excessive" left ventricular hypertrophy with reduced resting systolic wall stress that allows for supernormal ejection performance. If aortic stenosis is uncorrected, this pattern persists until adulthood. The effect of removing the aortic pressure gradient on left ventricular hypertrophy and wall stress in children with congenital aortic stenosis ...

The influence of sex hormones on the development of left ventricular hypertrophy was investigated in baroreceptor-denervated rats. A significant increase (p less than 0.01) in the left ventricular weight/body weight ratio was observed in male but not in female rats 15 days after operation, compared to age- and sex-matched sham-operated rats. This differential hypertrophy occurred despite the de...

Septal and left ventricular posterior wall (LVPW) thicknesses and their ratios were studied at the left ventricular outflow tract and left ventricular cavity in 66 patients with echocardiographically diagnosed left ventricular concentric hypertrophy, 20 with idiopathic hypertrophic subaortic stenosis (IHSS), and 34 normal subjects. Concentric hypertrophy was due to hypertension in 41 subjects a...
