Filter by:Arterial calcification is an independent predictor of coronary events associated with a 3-4 fold increased risk of cardiovascular events. Currently, no effective intervention exists to reduce arterial calcification. However, recent studies showed that vitamin K may reduce ongoing calcium deposition in the arteries, and thereby inhibit arterial calcification. The primary objective is to determine if MK-7 supplementation leads to stabilization or attenuation of ongoing calcium deposition in the femoral artery as quantified by 18F-NaF PET/CT imaging in patients with type 2 diabetes and arterial disease.
The purpose of this study is to establish the safety and feasibility of the Edwards SAPIEN 3 valve in subjects with mitral annular calcification (MAC) associated with mitral stenosis (MS) and/or mitral regurgitation who are at high-risk for mitral valve surgery or deemed inoperable due to the extent of calcification.
Patients with Systemic lupus erythematosus (SLE) are known to present an increased risk of osteoporosis and cardiovascular calcification. It has also been suggested that bone remodelling and cardiovascular calcification are regulated by the same mechanisms, but inversely in terms of calcium deposition, as osteoporosis is often associated with cardiovascular calcification. Inflammatory and immune factors have been implicated in these two processes. The role of the RANKL/OPG system in osteoclast differentiation has been elucidated over the last ten years. RANKL induces differentiation of monocytes-macrophages into osteoclasts, while, inversely, OPG exerts an inhibitory role by inactivating RANKL. Differentiation of smooth muscle cells into osteoblasts in the vessel wall induces calcification, and this phenomenon is counterbalanced by differentiation of monocytes into osteoclasts. Although the role of the RANKL/OPG ratio in the pathogenesis of osteoporosis has now been clearly established, its role in vascular calcification is only hypothetical at the present time. This study will focus on patients with SLE diagnosed and followed in the Amiens University Hospital Internal Medicine and Nephrology departments
Study a sample of patients in primary prevention, moderate cardiovascular risk (n = 83 patients), with normal, non-diabetic renal function. The investigators quantify the phophocalcic intake and excretion, realizing a food examination and a urine collection of 24 particular. The investigators will measure plasma levels of FGF23 serum calcium, phosphatemia, the investigators will calculate the tubular reabsorption of phosphate. The investigators will conduct a quantitative assessment of coronary calcification by a non-injected CT scan, measuring semi automated way Agatston calcium score. There will be an analysis of collinearity. An adjustment will be made for confounding variables in a generalized linear regression model.
The purpose of this study is to understand the effects of fish oil supplement (containing parts of omega-3 fatty acids) on inflammation. The investigators are aiming to identify which dose of the fish oil supplement is the most effective. The name of the fish oil supplement is "SPM Emulsion."
This is a prospective open-label trial that will enroll 12 patients with systemic sclerosis (SSc) and at least one calcinotic lesion of the hands that is palpable on physical examination and also measureable on hand radiographs, at one single center. Each subject will receive treprostinil orally for 12 months, and follow-up evaluations will be performed every 3 months. Our main objective is to determine whether oral treprostinil is safe, and effective in reducing calcinosis in patients with SSc. We hypothesize that calcinosis is a result of microvascular injury and ischemic damage, and that therefore treprostinil may be beneficial in the treatment of calcinosis in patients with SSc.
The study aims to determine the effect size of magnesium and bicarbonate supplementation as a basis for future randomized controlled trials aiming at the T50-guided improvement of hard clinical endpoints in dialysis patients.
This study examines patients on chronic hemodialysis with non-valvular atrial fibrillation, who have a CHA2DS2-VASc Score of ≥ 2 and therefore are candidates for or already receive a vitamin K antagonist. The first question is whether replacement of the vitamin K antagonist by rivaroxaban is able to slow progression of vascular calcification. The second question is whether addition of vitamin K2 to rivaroxaban can further slow down or even halt the progression of vascular calcification.
Randomized placebo-controlled double-blinded interventional trial to investigate the effect of oral magnesium supplementation on vascular calcification in subjects with chronic kidney disease. We hypothesize that oral magnesium supplementation will reduce vascular calcification in subjects with chronic kidney disease while not decreasing bone mineral density.
The primary objective of the current study is to determine whether Ataciguat (HMR1766) slows progression of valve calcification in patients with moderate calcific aortic valve stenosis. Secondary and tertiary objectives are to determine whether Ataciguat slows progression of aortic valve function, reduces systemic inflammation, and prevents left ventricular dysfunction in patients with moderate calcific aortic valve stenosis.
