The prevalence of peripheral arterial disease (PAD) increases with age, affecting 3% under 60 years, rising to >20% over 75 years. Whilst 40% of PAD patients are symptomatic, around 60% are asymptomatic. PAD is a reliable marker of future vascular disease such as Congestive Heart Disease (CHD) and stroke, and a substantial public health issue. In the UK around 100,000 people are diagnosed every year resulting in 60% of PAD patients dying from MI and 12% from stroke. PAD is present in ~30% of the diabetic population and considered to be a greater risk-factor than neuropathy for foot ulceration. The purpose of this study is to test the hypotheses that using the new device (Dopplex Ability), A) the ABPI test can be performed quicker than Doppler, B) obviates the need to rest the patient and C) provides results in good agreement with Doppler. The analysis methods used were Bland Altman agreement plots, equality plots and Pearson correlation.
