Active clinical trials for "Vascular Diseases"

The REGAL study is a European, prospective, multi-center Post-Market Clinical Follow-up (PMCF) trial providing additional data including health economics data to support the use of the ELUVIA stent in the treatment of lesions located in the femoropopliteal arteries.

The objective of this study is to assess the clinical use of the Bard® UltraScore™ Focused Force PTA balloon in a heterogeneous patient population in a real world, on-label clinical application.

As principal objective, the study aims to: Describe the spectrum and evaluate the frequency of angiodysplasia of the nevrax; Establish the physiopathological basis of Fowler's syndrome; Identify FLVCR2 partners and the signaling pathways involved; Test new candidate genes: GPR124 and possible partners of FLVCR2. As second objective, the study aims to: perform phenotype / genotype correlation if necessary; and propose a prenatal diagnosis in families with identified mutations.

This study investigate CT images of patients with spontaneous isolated superior mesenteric artery dissection (SISMAD). The investigators also further analyze the CT morphological differences between different options, aiming to determine "alarming CT character" during initial conservative treatment.

In coronary pathology, persistent platelet hyperresponsiveness under antiplatelet therapy, which is often referred to as "antiplatelet resistance," is predictive of increased risk of thrombotic recurrence as well as hyper-Inhibition of this aggregation may be predictive of a hemorrhagic risk. But no study has shown that the adaptation of treatment based on platelet aggregation tests has a benefit: the management of antiplatelet treatments through the search for antiplatelet resistance (APR) is not recommended by the European Society of Cardiology (ESC) in the context of coronary angioplasty (IIIA), while this is a common practice in neurovascular pathology.

Peripheral arterial disease is a condition in which the arteries become narrowed due to a build up of cholesterol, as a result, blood cannot flow efficiently through the arteries and this can compromise the parts of the body supplied by these arteries. In its most severe form, peripheral arterial disease can lead to decomposition of tissues in the feet, leading to ulcers or gangrene. Patients with peripheral arterial disease undergo procedures to improve blood flow. However, there are often multiple arteries to treat and each intervention carries risk. It therefore can be difficult to judge how much treatment is sufficient to promote healing. Laser Speckle Imaging is a technique used to demonstrate blood flow in the skin. It is hoped that changes in skin blood flow, as measured by LSI, immediately after a procedure to improve blood flow, may help in the decision making as to whether further intervention is necessary. An LSI scan will be performed before a procedure for tissue loss and immediately after it is performed. The patient's clinical records will then be checked to see whether the wound has improved and whether the difference in LSI scans correlated with this.

Prevalence of type 2 diabetes (T2D) is increasing worldwide over the last two decades; in these patients the rate of all-cause and cardiovascular (CV) mortality is several folds higher than in the general population, configuring a major public health problem. The clinical phenotype is the main determinant of such high mortality risk; however, a relevant role is played by the disease duration, with a significant interaction with metabolic control. However, for T2D the diagnosis does not correspond to the true onset of the disease, and a high lethality rate also in patients with recent onset of the disease cannot be excluded. Robust evidence supports this hypothesis, showing as in subjects with new-onset T2D, the mortality risk is superimposable, and even higher, than that observed in people with overt and long-term T2D. In this complex scenario, it would be desirable an early identification of high-risk patients, in which an accurate estimation of risk of complications, coupled with appropriate and timely interventions, might help in reducing the risk of encountering premature mortality. The present study was design to address this specific issue.

This study evaluates the pain score numerical rating, after sciatic analgesic continuous block, in patients with ischemic pain before surgery of limb revascularization. All patients received those blocks to control ischemic severe pain.

The study will investigate the clinical features, acute management and follow up of patients affected by spontaneous coronary artery dissection

Aim and background: This study will seek to identify physiological and biochemical factors explaining and predicting a higher than expected central (aortic) blood pressure (BP) in patients with chronic kidney disease (CKD). The basic hypothesis of the study is that the degree of aortic calcification is an important component of elevated central BP, which, in turn, is important for the organ-damage and increased risk of cardiovascular disease associated with CKD. Methods: Adult patients with varying degrees of CKD undergoing scheduled coronary angiography (CAG) at Aarhus University Hospital will be included in this study. During the CAG procedure, systolic and diastolic BP is determined in the ascending part of aorta by a calibrated pressure transducer connected to the fluid-filled CAG catheter. Simultaneous with the registration of invasive aortic BP, estimation of central BP is performed using radial artery tonometry (SphygmoCor®), while a corresponding brachial BP is also measured. Prior to the CAG, a non-contrast CT scan of aorta in its entirety will be performed to enable blinded quantification of calcification in the wall of aorta and coronary arteries. Furthermore, echocardiography, resting BP measurement and a range of blood- and urine samples will be performed.
