Iron Mediated Vascular Disease in Sickle Cell Anemia Patients

Sickle Cell Disease

The purpose of this research study is to determine the frequency and severity of iron overload in patients with Sickle Cell Anemia and its relationship to blood vessel function. The investigators hypothesize that intermittent transfusions that these patients receive during hospitalizations produces significant iron overload and impairs blood vessel relaxation.

Magnetic Resonance Imaging to Identify Characteristics of Plaque Build-Up in People With Peripheral...

Peripheral Vascular Diseases

Peripheral arterial disease (PAD) is a disease in which fatty build-up, or "plaque," accumulates in the peripheral arteries. People with PAD often experience leg pain while walking due to reduced blood flow to the legs. This study will use magnetic resonance imaging (MRI) techniques to examine how specific features of plaque build-up in the leg arteries affect walking ability, leg strength, and balance in people with PAD.

Sleep Apnea, Coronary Atherosclerosis and Heart Failure in Diabetes Patients With Nephropathy

Sleep ApneaDiabetic Nephropathy Type 25 more

Background: Diabetes, and especially diabetic kidney disease is associated with the development of cardiovascular disease such as calcification in the coronary arteries and heart failure. Sleep apnea is frequent among patients with diabetes and diabetic kidney disease and sleep apnea itself is a solitary risk factor in the development of cardiovascular disease. Nonetheless, sleep apnea is underdiagnosed in diabetes patients because of a discrepancy between sleep apnea severity and actual oxygen deficiency symptoms which makes the diagnosis difficult. For that reason, many diabetics have undiagnosed sleep apnea together with cardiovascular disease. Early discovery of sleep apnea among high risk diabetic patients may therefore be considered crucial before cardiovascular complications develop. For this reason, sleep apnea screening of high-risk diabetics can possibly improve early diagnostics of cardiovascular disease. Aim: This study will seek to establish the association between obstructive sleep apnea (OSA) and coronary calcification and heart failure in patients with diabetic kidney disease. The basic hypothesis of the study is that patients with diabetic kidney disease and concurrent OSA have a higher prevalence and severity of coronary calcification and heart failure compared to patients without OSA. Methods: Diabetic adult patients with scheduled check-ups at Steno Diabetes Center Aarhus, or Department of Renal Medicine on Aarhus University Hospital will be included in the study. Firstly, all included patients are screened for sleep apnea with the devices SomnoTouch® and ApneaLink®. Based on the sleep apnea determination; 40 patients with moderate-severe sleep apnea are compared with 40 patients without sleep apnea. In both groups, the patients are examined for calcification in the coronary vessels using a CT-scan while the function of the heart is examined by ultrasound (echocardiography). The stiffness of aorta is measured and performed using radial artery tonometry (SphygmoCor®). Furthermore, range of blood- and urine samples will be performed The perspectives are that patients with diabetes should be regularly evaluated for sleep apnea and that patients with moderate/severe sleep apnea should undergo further examination for cardiovascular disease even though the patients don't display any symptoms of either cardiovascular disease or sleep apnea.

COVID-19 Testing in Patients With Vascular Disorders

Covid19

Background: To investigate the prevalence of SARS-CoV-2 infection in hospitalized patients with vascular disorders after implementing institutional and governmental safety measures. Materials and Methods: Vascular patients (VPs) admitted to our tertiary care hospital were routinely tested for SARS-CoV-2 infection on a two days basis between March and December, 2020. The prevalence of SARS-CoV-2 was compared between VPs and two independent Austrian populations (April and November 2020) tested by the Austrian Ministry of Science. The results were also compared to a cohort of health care personnel (HCP) working in close proximity to the study patients, tested weekly, between March and December, 2020. RT-PCR and antigen test were used to detect SARS-CoV-2.

Physical Therapy in Lipedema Surgery

AssessmentLipedema2 more

The goal of this observational study or clinical trial is to know evaluate the effects of a modified Complete Decongestive Therapy protocol using the Godoy Method in the postoperative period following lipedema surgery. The main question it aims to answer are: if the treatment is effective on pain reduction, edema resorption, mobility improvement in short term and follow-up at 90 days if the treatment is effective on preventing complications of these participants after surgery Participants have been treated in the lasts years and authors recover information of the effects of the treatment. Researchers will compare sub-groups of participants depending on the number of physical therapy sessions received

The Effect of Anacetrapib on Vascular Function and Arterial Stiffness

Atherosclerotic Cardiovascular DiseaseVascular Disease

There are currently no studies evaluating the effect of anacetrapib on blood vessel function and stiffness of the arteries. The REVEAL-Vasc trial will assess whether anacetrapib, in addition to atorvastatin (LDL-C lowering drug) treatment, results in greater endothelial-dependent vascular function and aortic stiffness in patients with established cardiovascular disease, compared to adding placebo. Participants will be asked to provide a blood sample and pulse Wave Velocity/Pulse Wave Analysis and Flow Mediated Dilation will be carried out to assess blood vessel function and stiffness of the arteries. REVEAL-Vasc is an investigator led sub-study of HPS3/TIMI 55: REVEAL (Randomized Evaluation of the Effects of Anacetrapib through Lipid modification): A large-scale, randomized placebo-controlled trial of the clinical effects of anacetrapib among people with established vascular disease (NCT01252953) which is coordinated by OXFORD CTSU. No treatment will be received on this sub-study, therefore only participants who have been enrolled in HPS3/TIMI55 REVEAL in which participants received anacetrapib with atorvastatin or placebo will be considered for this trial.

Action in Diabetes and Vascular Disease Preterax and Diamicron MR Controlled Evaluation Post Trial...

Diabetes MellitusType 2

The study is designed to determine the long term, post trial effects of the two interventions studied in ADVANCE (routine blood pressure lowering with perindopril-indapamide as compared with placebo and intensive gliclazide-MR based glucose control as compared to standard guideline based glucose control) in individuals with type 2 diabetes at high risk of cardiovascular events. The long term, post randomization effects of the two study interventions will be investigated separately as they were for the main trial. This study will clarify and quantify the long-term, post trial (often referred to as legacy) effects of these two interventions in a broader population of patients with type 2 diabetes from high and low to middle income countries, and in the setting of comprehensive cardiovascular risk factor treatment. With the ADVANCE trial infrastructure and surveillance system already in place, the implementation of extended follow-up will be feasible. The conclusions of this follow up study will have profound clinical implications for the care of patients with type 2 diabetes around the world.
