Objective: Peripheral arterial disease (PAD) is a common cardiovascular complication in systemic lupus erythematosus (SLE) patients [1]. PAD is objectively diagnosed with ankle-brachial index (ABI), which can be measured by the Doppler method, or oscillometric technique [2]. In Ghanaian SLE patients, we compared the utility of oscillometric ABI to Doppler ABI, which is the ‘gold standard’.

Method: ABI was measured using 8 MHz hand-held Doppler (LifeDop 250, Summit Doppler) and oscillometric technique (Vasera 1500N, Fukuda Denshi) in 80 SLE patients (160 legs). PAD was defined as ABI < 0.9 in at least one leg.

Results: There prevalence of PAD by oscillometric technique was higher than that of Doppler technique (32.5% vs 23.8%, p = 0.004). There was fair level of agreement between PAD by Doppler and oscillometric techniques (κ = 0.36, p = 0.003). Doppler ABI correlated with oscillomteric ABI in the right leg (r = 0.34, p = 0.005), but not in the left leg (r = 0.18, p = 0.127). Reliability analysis showed that Doppler-ABI does not agree with oscillometric ABI in both right (intraclass r = 0.23, p = 0.13) and left (intraclass r = 0.31, p = 0.061) legs.

Conclusion: In Ghanaian SLE patients with high prevalence of PAD, measurement of ABI using oscillometric technique does not agree with Doppler-based ABI.
