Sevelamer, Fetuin-A and Endothelial Dysfunction in CKD
Vascular DiseasesVascular calcification and endothelial dysfunction (ED) contribute to the development of cardiovascular disease (CVD) in patients with chronic kidney disease (CKD). Sevelamer, a non-calcium based phosphate binder, has been shown to attenuate cardiovascular calcification in CKD patients while the exact mechanism has not been clarified. This study was designed to investigate the effect of short-term sevelamer treatment on both serum fetuin-A concentrations and ED seen in CKD patients.
Home Blood Pressure-guided Antihypertensive Intervention for Elderly (HBP-GUIDE) Study
Cardiovascular DiseaseVascular Disease1 moreThe purpose of this study is to determine whether blood pressure control by home blood pressure monitoring exerts beneficial cardioprotective effects rather than by clinic blood pressure monitoring in elderly patients.
The Effect of Folic Acid on Atherosclerosis, Cognitive Performance and Hearing
AtherosclerosisVascular Disease4 moreThe purpose of this study is to determine if folic acid supplementation can slow down atherosclerotic progression, age-related cognitive decline and age-related hearing loss.
Calcium for Pre-Eclampsia Prevention (CPEP)
Cardiovascular DiseasesEclampsia6 moreTo evaluate the efficacy of 2 grams per day of oral calcium supplementation in reducing the combined incidence of hypertensive disorders of pregnancy: pre-eclampsia, eclampsia, and the HELLP Syndrome (hypertension, thrombocytopenia, hemolysis, and abnormal liver function). The National Institute of Child Health and Human Development (NICHD) initiated the trial in 1991, with joint funding provided by the National Heart, Lung, and Blood Institute in fiscal years 1992, 1993, and 1995.
Asymptomatic Carotid Artery Plaque Study (ACAPS)
Cardiovascular DiseasesCarotid Stenosis4 moreTo determine whether warfarin or lovastatin alone or in combination retarded the progression of atherosclerotic plaques in the carotid arteries of high risk individuals with asymptomatic carotid stenosis. Also, to determine if a full scale trial was feasible.
Treatment of Hypertension
Cardiovascular DiseasesHeart Diseases2 moreTo determine whether the long-term treatment of essential hypertension without significant target organ disease materially influenced mortality and/or cardiovascular renal morbidity.
The Effects of Interrupting Prolonged Sitting With Intermittent Exercise on Postprandial Lipemia...
Metabolic Syndrome XAtherosclerosis8 moreThe purpose of this study is to investigate the effect of interrupting prolong sedentary behavior with interval exercise on postprandial metabolism following a high fat glucose tolerance test.
Locally Applied Pressure-induced Vasodilatation
Vascular DiseasesMeasure microcirculatory responses after localized ischemia obtained by local application of pressure (laser speckle).
Cooling Lower Leg Skin to Prevent Venous Leg Ulcers in Patients With Poor Vein Circulation
Venous DiseaseVenous Vascular Diseases and Syndromes2 moreLeg vein circulation problems can damage the skin of the lower legs, especially around the ankles, by making it discolored, hard, itchy, red, and swollen. Ulcers often develop. Inflammation is often present in the damaged skin. This study will test whether using a special low compression, cooling, boot-like gel wrap placed around the damaged skin of the lower legs will improve the skin circulation and prevent leg ulcers. The study hypothesis is: A cryotherapy, low-compression cooling gel wrap (CW) plus usual care (UC) (leg elevation, compression stockings) intervention compared to a low compression non-cryotherapy "sham" wrap (NW) plus UC will reduce tissue blood flow (perfusion units) and decrease the incidence of venous leg ulcers (VLUs) during the 9-month study period in individuals with Stage 4 and 5 venous insufficiency.
Lowering the Risk of Operative Complications Using Atorvastatin Loading Dose
Myocardial InfarctionPeripheral Vascular Disease1 morePatients submitted to noncardiac surgeries are at increased risk of serious cardiovascular complications. Statins have shown to lower cholesterol levels and reduce cardiovascular events in other scenarios. The objective of this study is to explore the effects of atorvastatin, as compared with placebo, on the 30-day risk of a composite of death, nonfatal Myocardial Injury after Noncardiac Surgery (MINS), or stroke among patients who undergo noncardiac surgery.
