Mucopolysaccharidoses (MPS) are a heterogeneous group of lysosomal storage disorders, due to deficiency of glycosaminoglycans breakdown enzymes. MPS type III is also known as SanFilippo syndrome, which is further subdivided into four distinct forms--A, B, C and D--caused by different enzyme deficiencies, but with similar clinical characteristics. Cardiac(More)
BACKGROUND Few studies have addressed the impact of moderate unsupervised everyday physical activity in patients with chronic heart failure (CHF). DESIGN We investigated the effects of a 12-week walking programme as the sole exercise intervention on heart rate recovery (HRR), index of the autonomic system equilibrium, serum modulators of endothelial(More)
BACKGROUND Treatment with statins is considered a first line therapy in atherosclerotic disease. Intraplaque angiogenesis is involved in plaque progression and instability. It remains unclear whether the beneficial effect of statin treatment in humans is achieved through reduced intraplaque angiogenesis. The aim of this study was to evaluate the capillaries(More)
BACKGROUND Increased levels of plasma brain natriuretic peptide (BNP) are observed in patients with congestive heart failure, hypertension, left ventricular hypertrophy, and acute myocardial infarction. However, there are no data on serial changes in plasma levels of BNP in patients undergoing coronary angioplasty. HYPOTHESIS The study was undertaken to(More)
BACKGROUND Percutaneous transluminal treatment of a thrombotic vein graft yields poor results. We have previously reported our experience with transluminal percutaneous coronary ultrasound thrombolysis (CUT) in the setting of acute myocardial infarction (AMI). This report describes the first experience with ultrasound thrombolysis in thrombus-rich lesions(More)
Endothelin-1 and cyclic guanosine monophosphate (c-GMP) peripheral vein plasma levels increase during coronary angioplasty, but the reason for this increase has not been elucidated. The purpose of this study was to investigate whether these changes are related to myocardial ischaemia, or to mechanical artery injury induced during the procedure. Thirty-two(More)
BACKGROUND Bosentan, a dual endothelin receptor antagonist, has been used for symptomatic improvement of patients with idiopathic pulmonary arterial hypertension (PAH) and specific types of secondary (e.g. scleroderma and human immunodeficiency virus infection) PAH, but its efficacy in patients with congenital heart disease and chronic thromboembolic(More)
To investigate if the response of the contralateral artery during coronary angioplasty (PTCA) is different in hypertensive than in normotensive patients and whether this response is related to plasma levels of endothelin-1 (ET-1). We examined the change in ET-1 plasma levels and the reactivity of the left circumflex artery (LCx) during PTCA of the left(More)
