Background.
In Sri Lanka the ABPI has not been used as a screening tool to detect peripheral arterial disease (PAD) in epidemiological studies.
This study was conducted to determine the best cutoff value of ABPI to detect PAD in Sri Lankan population.
Methods.
The ABPI measured by arterial Doppler to detect PAD was validated against colour duplex scan as the criterion using 165 individuals referred to vascular laboratory, National Hospital Sri Lanka.
In all selected individuals ABPI was measured and lower limb colour duplex scan was performed.
Narrowing of luminal diameter of lower limb arteries 50% or more was considered as haemodynamically significant and having PAD.
The discriminative performance of the ABPI was assessed using Receiver Operator Characteristic (ROC) curve and calculating the area under the curve (AUC).
The sensitivity and specificity of different threshold levels of ABPI and the best cutoff value of ABPI to detect PAD were determined.
Results.
ABPI 0.89 was determined as the best cutoff value to identify individuals with PAD.
At this level of ABPI high sensitivity (87%), specificity (99.1%), positive predictive value (98.9%), and negative predictive value (88.4%) were observed.
Conclusion.
ABPI ≤ 0.89 could be used as the best cut off value to detect PAD.
