The prevalence of peripheral arterial disease (PAD) is 3% to 10% in the general population, increasing to 15% to 20% in those older than 70 years. 1 The Reduction of Atherothrombosis for Continued Health survey showed that almost 66% of patients with PAD had clinical evidence of other vascular disease. 2 Coronary artery disease is the most common cause of death among patients with PAD (40%-60%), cerebral artery disease accounts for 10% to 20% of deaths, 1,2 and 10% of deaths have been attributed to other vascular events, mostly ruptured aortic aneurysm.Although PAD is a major cause of mortality and morbidity, postgraduate doctors have poor knowledge about this topic. 3 Schwarcz et al recorded a moderate percentage of correct answers by internal medicine interns when questioned with respect to prevalence, screening, and treatment of vascular diseases (48.9%, 33.8%, and 45.0%, respectively). 4 Although the ankle-brachial index (ABI) is considered a reliable and accurate vascular biomarker in primary and secondary prevention of cardiovascular events, 5 Wyatt et al documented a poor level of baseline knowledge of calculation and interpretation of ABI among internal medicine residents, irrespective of the year of residency. 6 Likewise, Chaudru et al reported poor scores of 22%, 13%, and 41% among residents from 6 different medical schools in France regarding correct ABI measurement, calculation, and interpretation, respectively. 7 Therefore, it is not surprising that Campbell et al recorded uncertainty and disagreement about the skills expected from medical students by their tutors, with only one-third of the instructors considering the ability to estimate ABI using a Doppler device as necessary. 8 In agreement with deficient PAD knowledge at pre-and immediate postgraduate level, a survey in central Greece documented that PAD remains underdiagnosed and undertreated not only due to insufficient patient information and screening but also due to lack of awareness and inadequate vascular examination by many physicians in primary care. 9
