Active clinical trials for "Peripheral Arterial Disease"

To determine the incidence of type II diabetes and cardiovascular disease among Mexican-American and non-Hispanic whites in a 15 to 24 year follow-up of the San Antonio Heart Study 1 participants. Also, to perform a 15 to 24 year mortality follow-up of the cohort and to examine the "Hispanic paradox".

This is a retrospective, multi-center study to assess the safety and performance by proactively reviewing pre-existing medical records and imaging of patients who had previous placement of FLUENCY® PLUS Vascular Stent Graft in iliac artery vessel(s) between January 2010 and March 2020.

Diabetic foot disease with a global incidence of about 6% is one of the most serious complications of diabetes, which brings great pain and economic burden to patients.In China, the incidence rate is 8.1%, and the amputation rate is 7.3%. Every year, more than 1 million diabetic patients have amputations, ranking first among non-traumatic amputations.According to the American Diabetes Association (ADA), the incidence of Peripheral Arterial Disease (PAD) in diabetic patients is twice that of non-diabetic patients, and the resulting lower limb ischemia is the main cause of the high mortality and disability rate of diabetic foot.According to the International Working Group on Diabetic Foot (IWGDF), about 50% patients with diabetic foot disease are complicated with PAD, and the degree of vascular stenosis is closely related to the prognosis.Severe limb ischemia is a higher cause of diabetic foot ulcer in China than in western countries.Atherosclerosis is the main pathological change of diabetic peripheral artery disease, and endothelial injury is the initial link of atherosclerosis.Heat shock protein 90 (HSP90) is a kind of important heat stress protein, which accounts for about 2-3% of the total protein in cells.It is involved in the correct folding and activation of intracellular proteins.Although Hsp90 is primarily involved in intracellular protective mechanisms, they can also be exposed to the plasma membrane and released in the extracellular space, resulting in detectable levels of Hsp90 in the blood.Extracellular heat shock proteins are involved in cell-cell communication as well as immune and inflammatory processes.Hsp90 promotes cell survival, migration, inflammation and angiogenesis, and is therefore considered a promising target for cancer therapy.This led to the development of specific HSP90 inhibitors.More recently, these inhibitors have also been tested in diabetic animals.The use of the HSP90 inhibitor 17-DMAG significantly reduced atherosclerotic lesions and induced a more stable plaque phenotype in a mouse model with hyperglycemia and hyperlipidemia.Hsp90 is upregulated in human carotid atherosclerotic plaques (especially in unstable areas of plaques) and in patients' serums, triggering autoimmune antibodies against Hsp90 in patients.Is HSP90 also present in serum of patients with diabetic peripheral arterial disease?Is there a relationship between secretory heat shock protein 90 and arterial disease?The study that HSP90 may be involved in the molecular mechanism of vascular endothelial barrier function impairment in diabetes will provide a new target for the early serological diagnosis and treatment of diabetic vascular disease.The aim of this study was to investigate the relationship between the degree of vascular disease and serum heat shock protein 90 in patients with type 2 diabetes.The study was divided into three groups: diabetic without PAD group, diabetic with PAD group and diabetic foot group.According to the degree of peripheral artery disease, the patients were divided into three groups, and the content of heat shock protein 90 in serum of the patients was detected.To analyze the correlation between the degree of peripheral arterial disease and the content of heat shock protein 90 in serum.

The VQI-DELTA Paclitaxel Device Safety Analysis seeks to assess the comparative safety of paclitaxel coated balloons and stents in the treatment of peripheral artery disease (PAD) through analysis of the VQI Peripheral Vascular Intervention (PVI) registry module using the DELTA system.

Cardiovascular pathologies (CV), the second leading cause of death just behind tumors, are particularly frequent in France and strongly mobilize the resources of the healthcare system (ambulatory and health facility). The French High Authority for Health (HAS) has defined major cardio-vascular risk factors (CVRF): smoking, high blood pressure (hypertension), elevated total cholesterol (TC) or LDL, decreased HDL cholesterol, type II diabetes and age, and predisposing CVRF or discussed: obesity, sedentary lifestyle, menopause, elevation of triglycerides and genetic factors. Lower-linb peripherial arterial disease (AOMI), even if asymptomatic, involves systemic atherial disease, responsible for mortality irrespective of the presence of CVRF. The prevalence of asymptomatic AOMI is 10 to 20% beyond 55 years old, and the associated mortality is 18 to 30% at 5 years. Individual screening is achievable by well-conducted clinical evaluation and systematic measurement of the simple, non-invasive Blood Pressure Index (BPI) in all subjects at risk. A BPI<0.9 indicates an event risk close to that of the symptomatic patient. However, if this strategy is recommended by the HAS, it is not carried out systematically in current practice. Therapeutic means available for the management of an asymptomatic AOMI are the identification and support for controllable CVRF such as smoking and nutrition (diet and physical activity) in the context of secondary prevention of atherosclerosis. Thus, the generalization of a systematique screening strategy of AOMI, allowing faster handling of CVRF by advices and Motivational Interviewing (MI), could have a significant impact, both clinically and economically. Patients could also benefit from this support in terms of quality of life both on the physiological dimension (effect of weight loss, correction of disorders of cardiac function, etc.), that on the psychic dimension (well-being of patients, management of disorders anxious). However, few studies have evaluated the benefit of such a strategy in terms of quality-adjusted life years (QALYs),none did it on a cost recovery basis. No such studies have been conducted in France. The feasibility of this project is based on the success of a pilot study conducted in Centre-Val de Loire region (France) in 2013. It showed that the implementation of a strategy of systematic screening of the asymptomatic AOMI based on the measurement of the BPI in high cardiovascular risk patients is feasible in current practice by general practitioners, and could be more efficient than interventions performed in current practice.

The objective of this project is to assess the fidelity and sustainability of in improving provider performance with Ankle Brachial Index (ABI) assessment and ulcer staging with the would ischemia foot infection (WIfI) tool for new patients with lower extremity ulcers due to peripheral artery disease (PAD) and diabetes mellitus (DM) at RHCs in the telemedicine network through a rural provider education program that is aligned with preexisting continuing medical education activities.
