Implication
May support targeted carotid screening in high-risk asymptomatic diabetics; leaves open prospective validation of yield and outcomes.
Structured PICO
P
Population
300 consecutive asymptomatic type-2 diabetic subjects (166 males, 134 females). Excluded: recent cerebrovascular event (≤ 6 weeks) or previous carotid surgery.
I
Intervention
Physical examination and duplex carotid scanning (screening strategy)
O
Outcome
Prevalence of carotid stenosis ≥ 60% or occlusion, and prevalence of carotid atherosclerosissurrogate
In asymptomatic type-2 diabetic patients, the prevalence of significant carotid stenosis is 4.7%, and screening yield may be optimized by targeting men with a history of coronary heart disease or an ABI <0.85.
