Filter by:Peripheral arterial disease (PAD) is one of the most common cardiovascular diseases in developed countries [1] and is an emerging problem in developing countries [2, 3]. The prevalence of PAD in European population studies ranged from 3.6 to 9.2 % and 10-20 % in those aged over 70 years [4]. In a recent meta-analysis, the prevalence of PAD in China increased gradually by age until mid-60s, after which the increase accelerated. In the early stages, PAD is mostly silent. With the progression of disease, it may manifest as intermittent claudication, pain at rest, non-healing ulcer and gangrene resulting in lower-extremity amputation [5]. PAD is a major cause of disability, loss of employment, and lifestyle changes, and is a marker for systemic atherosclerotic diseases. Patients with symptomatic PAD have at least a 30% risk of death within 5 years rising to almost 50% within 10 years, resulting primarily from myocardial infarction or stroke [4]. Despite the major health risks associated with PAD, it is generally not recognized by clinicians or the general public in comparison with other cardiovascular diseases. However, asymptomatic individuals also have higher risk of adverse cardiovascular events similar to those with symptomatic PAD [6]. Many studies have shown that public awareness of PAD is much lower than that of other diseases. It has been reported that awareness of PAD ranged from 20 to 36 %, whereas awareness of other common diseases was more than 60 % in the same population [6-9]. Awareness is important for patients and physicians, and the need for public awareness programs has been highlighted [10, 11]. There is paucity of published literature on public awareness of PAD in Asian countries. It is difficult to reduce the morbidity and mortality of untreated PAD without adequate public awareness of PAD and its risk factors and consequences [7]. Insights into public awareness of PAD will help in developing strategies for behavioral change communication and health promotion. In this study we aimed to assess awareness of PAD among adults in Hong Kong. The survey is designed to measure knowledge of factors that increase the risk for PAD and the clinical risk consequences of having PAD. These data will provide useful information to guide future local public cardiovascular educational efforts.
POLYTHESE® study is a retrospective, observational, multicentre, case series which examine short and long-term outcomes of using POLYTHESE®. This study will be done on Real World Data to describe the safety and performance of the device. PMCF Study.
The objectives of this study are: Evaluation of ultra-low iodine load CTA protocols of the aorta and lower extremities. To investigate whether dual-layer in combination with with virtual monoenergetic imaging (VMI) allows for reduction of contrast medium (CM) in CTA of the aorta and lower limbs i with sustained objective and subjective image quality parameters.
This randomized controlled study evaluates the effect of acupressure application on the pain level patients after angioography. The hypothesis of this study is that acupressure reduces pain levels and stabilizes hemodynamic variables.
The primary objective of this clinical investigation is to evaluate acute safety and efficacy of the S.M.A.R.T. RADIANZ™ Vascular Stent System, when used with the BRITE TIP RADIANZ™ Guiding Sheath and SABERX RADIANZ™ PTA Balloon Catheter, to deploy the S.M.A.R.T.™ Nitinol Stent, in the treatment of patients with obstructive iliac or femoropopliteal arterial disease via radial artery access.
The purpose of this study is to evaluate the safety and efficacy of interlocking detachable coils system in the treatment of Chinese patients with embolization of peripheral arterial in comparison with Interlock Fibered IDC Occlusion System
NICE guidelines recommend an Ankle brachial pressure index (ABPI) as the primary assessment tool for patients presenting with symptoms or are at a high risk of developing peripheral arterial disease (PAD). An ABPI is typically performed using a hand-held Doppler to listen and classify the arterial signal in the ankle and arm and the systolic pressure is taken in each to create a ratio of the pressure in the ankle to the arm. New Huntleigh Dopplex DMX Digital Dopplers within the vascular department have an arterial waveform display to help interpretation of the audible signal. This study aims to compare the audible and visual waveform traces on the Huntleigh Dopplex with the gold standard of ultrasound duplex to assess the accuracy of the trace using diagnostic measurements and the ability of clinicians to correctly identify audible and visual waveforms.
The rationale of this study is to confirm and support the clinical safety and performance of the products in a real-word population of 350 patients who underwent an endovascular intervention within standard-of-care (SOC) of the ilio-femoropopliteal artery, using at least 1 of the products (named above) from Cordis US Corp.
Peripheral arterial disease is a common, under-treated and under-researched issue. The vast majority of these patients often have multiple issues which can be improved with targeted behavioural change interventions. NICE has recommended that supervised exercise is the mainstay of treatment for intermittent claudication (ischaemic muscle pain on walking due to blocked and narrowed arteries). However, in the vast majority of UK hospitals, this isn't undertaken, and with the issues around group-based sessions and repeated visits to hospitals, this treatment option is not available with the coronavirus pandemic. This is a single-centre randomised control trial in 60 patients with peripheral arterial disease attending the Freeman Hospital. Patients will be randomised to either an enhanced behavioural change intervention targeting multiple health behaviours vs a simple walking intervention. Also, some patients will be involved in focus groups to understand their experience of the intervention and whether it is feasible and acceptable, allowing changes to be made to the program. The primary outcome will be to assess the feasibility and acceptability of the program. We will also be assessing multiple secondary outcomes including functional capacity, quality of life, sleep quality and smoking and alcohol reduction.
ORIGINS-RCE is an observational, cross-sectional, two-arm study aimed at determining if an individual's ethnic origin influences the number of blood vessel-forming stem cells in the bloodstream. Circulating progenitor cells will be enumerated and the distribution patterns of these cell types will be assessed to determine if these parameters differ between individuals of South Asian origin and European origin. Specifically, this study will evaluate if differential regenerative cell exhaustion (RCE) may account, at least in part, for the differences in cardiovascular risk reported between individuals of South Asian vs European origin.
