Sponsor's own description

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.
