Aim. This observational study (Survey of Peripheral Arterial Disease Epidemiology, SPADE) evaluated the prevalence of asymptomatic peripheral arterial disease (PAD) in general practice.
Methods. PAD was determined as an ankle-brachial pressure index (ABI) <0.9 measured with Doppler ultrasound. Included patients had a history of ischemic events and/or risk factors for PAD, but no spontaneous complaints of intermittent claudication. Patients with an ABI <0.9 filled in a standardized questionnaire and their drug use was registered. A total of 4 536 patients was included.
Results. The prevalence of PAD was 18.7% for the total population, 26.5% for those with a history of ischemic events and 15.2% for those without such history. The prevalence increased with age, but was independent of gender. A standard questionnaire revealed leg pain when walking uphill or when hurrying in 2/3 of patients with an ABI <0.9 and in 45% criteria for claudication were met.
Conclusion. ABI detects PAD in a considerable number of asymptomatic patients at increased risk and followed in general practice. When properly questioned almost half of these patients appear to have intermittent claudication.
