Peripheral artery disease patients are poorly aware of their disease

Abstract

Objectives. We hypothesized, that patients with peripheral arterial disease (PAD) are less aware of risk factors and possible outcomes of the disease compared to patients with coronary artery disease (CAD), which are similar. Hence, the aim of this study was to evaluate awareness of and attitudes towards PAD and CAD among patients, who are already diagnosed with either disease. Design. A cross-sectional descriptive study was performed. Basic demographics, the presence and awareness of risk factors for PAD and CAD; perceived systemic and limb consequences, severity of PAD and CAD, self-reported knowledge about other non-vascular illnesses were assessed using an anonymous questionnaire. Results. 203 were invited and 157 (77%), 63 with PAD and 94 with CAD, patients agreed to take part in and completed the survey. Basic demographic characteristics were similar in both groups, except for the level of education: PAD patients were less educated compared to CAD patients (p = .002). Only 35% of PAD patients were familiar with the definition of PAD (key words were registered) in contrast to 52% CAD definition awareness among CAD patients (p = .034). PAD patients were significantly less familiar with other common diseases (p = .002) and risk factors for both PAD (p < .001) and CAD (p = .003) in comparison to equivalent CAD group parameters. Conclusions. PAD patients are less aware of risk factors for PAD and atherosclerosis in general, other illnesses and have lower level of education, which may negatively affect overall management of this complex disease.
