Abstract

OBJECTIVE:

To evaluate the epidemiology and predictors of asymptomatic peripheral artery disease (PAD) in patients with a single previous coronary or cerebrovascular event in the Arabian Gulf.

METHODS:

This was a cross-sectional, multicenter, observational survey in consecutive patients (≥18 years) with documented previous coronary and/or cerebrovascular atherothrombotic event in the United Arab Emirates (UAE), Kuwait and Qatar (64 centers), from October 2008 to December 2010. PAD was defined as an ankle brachial index <0.9 in at least one leg.

RESULTS:

The overall mean age of the cohort (n = 2110) was 54 ± 11 years with only 14% being female (n = 303). The prevalence of asymptomatic PAD was 13.7%, with the highest prevalence seen in Kuwait (16.3%) and the UAE (14.7%) and the lowest in Qatar (5.3%). There were significant differences in the prevalence of asymptomatic PAD among the ethnic groups (p < 0.001): it was highest among the local Arabs and Caucasians at 19% and lowest among South East Asians (6%). The multivariate logistic model demonstrated that the most significant predictors of PAD were old age (adjusted odds ratio [OR], 1.04; 95% CI: 1.02-1.05; p < 0.001), female gender (OR, 1.56; 95% CI: 1.06-2.29; p = 0.024), ethnicity (OR, 0.39; 95% CI: 0.19-0.79; p = 0.009), smoking (OR, 1.70; 95% CI: 1.22-2.37: p = 0.002) and diabetes mellitus (OR, 1.49; 95% CI: 1.14-1.94; p = 0.004).

CONCLUSIONS:

PAD is prevalent in the Arabian Gulf and is more likely to be associated with old age, females, ethnicity, smokers and those with diabetes mellitus.
