BACKGROUND In patients with systolic heart failure, high levels of circulating aldosterone are associated with an adverse prognosis, and mineralocorticoid receptor blockade improves survival. The prognostic significance of cortisol that may also bind and activate the mineralocorticoid receptor in chronic heart failure is unknown. METHODS AND RESULTS Serum(More)
BACKGROUND Enzyme replacement therapy with recombinant alpha-galactosidase A reduces left ventricular hypertrophy and improves regional myocardial function in patients with Fabry disease during short-term treatment. Whether enzyme replacement therapy is effective in all stages of Fabry cardiomyopathy during long-term follow-up is unknown. METHODS AND(More)
BACKGROUND In this prospective follow-up study, the effect of myocardial fibrosis on myocardial performance in symptomatic severe aortic stenosis was investigated, and the impact of fibrosis on clinical outcome after aortic valve replacement (AVR) was estimated. METHODS AND RESULTS Fifty-eight consecutive patients with isolated symptomatic severe aortic(More)
OBJECTIVE The long-term effects of enzyme-replacement therapy (ERT) in Fabry disease are unknown. Thus, the aim of this study was to determine whether ERT in patients with advanced Fabry disease affects progression towards 'hard' clinical end-points in comparison with the natural course of the disease. METHODS A total of 40 patients with genetically(More)
BACKGROUND The Global initiative for chronic Obstructive Lung Disease (GOLD) defines COPD as a fixed post-bronchodilator ratio of forced expiratory volume in 1 second and forced vital capacity (FEV1/FVC) below 0.7. Age-dependent cut-off values below the lower fifth percentile (LLN) of this ratio derived from the general population have been proposed as an(More)
Friedreich's ataxia is a rare hereditary, predominantly neurologically defined multisystem disorder of mitochondrial function. Although the gene defect has been identified, the precise pathophysiology of the deficient mitochondrial protein, frataxin, is unknown. Besides the characteristic features of spinocerebellar ataxia the heart may also be affected,(More)
BACKGROUND The differential diagnosis of hyponatremia is often challenging because of its association with multiple underlying pathophysiological mechanisms, diseases, and treatment options. Several algorithms are available to guide the diagnostic approach to hyponatremia, but their diagnostic and clinical utility has never been evaluated. We aimed to(More)
The widely shared enthusiasm about the cardioprotective potential of estrogenic compounds has come to an abrupt halt since randomized trials failed to show a cardiovascular risk reduction in postmenopausal women. This was unexpected because observational studies had strongly suggested that hormone replacement therapy would reduce the incidence of(More)
BACKGROUND Matrix metalloproteinases (MMP) and their tissue inhibitors (TIMP) are involved in cardiac remodelling. The prognostic utility of TIMP is unknown in chronic heart failure (CHF). AIMS We investigated the association of plasma levels of soluble MMP-9 and TIMP-1 with clinical, laboratory and echocardiographic parameters and estimated their(More)
Patients' health-related quality of life is increasingly being included as an additional endpoint when evaluating the treatment of chronic heart failure. Although generic self-report instruments measuring health-related quality of life are available, there is a lack of disease-specific instruments covering various dimensions of quality of life with high(More)
