title: Targeted screening for peripheral arterial disease in general practice: a pilot study in a high risk group.
abstract: BACKGROUND
  Screening of high-risk groups for peripheral arterial disease has been advocated because the condition underdiagnosed and secondary prevention can reduce cardiovascular event rates.
  
  
  OBJECTIVE
  To establish the feasibility of screening for peripheral arterial disease in people aged 60 years or over with hypertension, and to estimate the potential to improve secondary preventive treatment.
  
  
  METHODS
  Pilot study and cross-sectional survey.
  
  
  METHODS
  Large general practice in north-east Scotland.
  
  
  METHODS
  People aged 60 years or over with hypertension but no cardiovascular disease or diabetes were identified from computer records and invited to a screening clinic. Data were collected on ankle brachial pressure index (ABPI), preventive treatment, and risk factors.
  
  
  RESULTS
  Of 705 potentially eligible patients, 443 (63%) agreed to participate. Sixty-four were excluded and 364 of 379 patients (96%) attended screening. Thirty patients had peripheral arterial disease (ABPI of 0.9 or less), of whom 24 (7%; 95% confidence interval [CI] = 4 to 10%) were previously undiagnosed. Fifteen (50%) patients took antiplatelets, 13 (45%) had cholesterol <5 mmol/l, and 16 (53%) had blood pressure below 140/85 mmHg. Twenty-two (73%) patients were non-smokers, 14 (47%) had low-fat diets, two (7%) were physically active, and three (10%) ate recommended amounts of fruit and vegetables.
  
  
  CONCLUSIONS
  It is feasible to screen for peripheral arterial disease in primary care, but its prevalence is lower than anticipated. There is room for improvement in secondary preventive treatment and lifestyle, so a structured programme could still have important benefits for survival.
