Active clinical trials for "Vascular Diseases"

Pulmonary vascular disease and cardiac performance in extreme preterm infants: A prospective cross-sectional study

Comparison of twà different nociception monitors during general anesthesia

The process of population aging that is occurring in developed societies represents a major challenge for the health system. The aim of this study is to analyze factors that have an influence on early vascular aging (EVA), estimated by carotid-femoral pulse wave velocity (cf-PWV) and Cardio Ankle Vascular Index (CAVI), and to determine differences by gender in a Chinese population.

Traditionally, people have always been focusing on vascular injuries by angiography. Recent years, the investigators have further known that the pathological foundation of various cardiovascular complications not only lies in the vascular lumen, but also vessel wall. Therefore, now it is possible to detect and prevent vascular disease early. There are many influencing factors on functional and structural damages of vessels, including genetic and environmental factors. The investigators have done many researches on populations of the Han nationality, which has the largest population in China. Thus, the investigators further wonder whether the function and structure of vessel differ in the She Minority of a remote southern region in China. The investigators will enroll 150 subjects of two ethnic groups respectively in the local population， namely She Minority and Han nationality. All subjects enrolled into the study will complete a questionnaire survey of the general situation and conduct vascular related examinations, including evaluation of arterial stiffness, arterial elasticity indexes, subclinical carotid atherosclerosis and biomarkers. The investigators will analysis vascular differences between the two populations and provide a theoretical basis for the specific strategies of prevention and treatment.

The blood concentration of the protein RANKL could be predictive of the calcification of the leg arteries, which is a major complication occurring during diabetes. The objective of the DIACART study is to show that blood RANKL concentration predict the progression of calcification of the leg arteries in diabetic patients, independently of other cardiovascular risk factors.

Thrombotic biomarkers and angiographic characteristics were compared among the de novo patients of central serous chorioretinopathy (CSC), polypoidal choroidal vasculopathy (PCV) and the control.

The aim of the study is to compare the diagnostic value of this non-invasive vascular imaging tool with the established vascular diagnostic methods for PAD in order to get prognostic data. A higher sensitivity of Fluorescence angiography in order to recognize progression of critical limb ischemia could lead to earlier therapeutic interventions and thereby increase limb salvage. A diagnostic gap would be closed.

The purpose of this study is to analyze genetic polymorphisms in genes encoding pro-inflammatory cytokines, and study the genetic predisposition to chronic periodontitis (CP) in combination with atherosclerotic cardiovascular (ACD) and aneurysmal diseases. The investigators will also try to identify oral bacteria in atherosclerotic plaques and aneurysmal walls and thrombus. Histological analyses of atherosclerotic plaques and aneurysmal wall will be performed.
