We investigated whether patients with peripheral arterial disease (PAD) with various serum levels of high-sensitivity C-reactive protein (hsCRP) differ in the frequency of atherosclerotic risk factors. Among 388 patients, hsCRP levels were (1) low, <1 mg/L, in 41 (10.6%) participants; (2) medium, from 1 to 3 mg/L, in 152 (39.2%) participants, and (3) high, >3 mg/L, in 195 (50.2%) individuals. According to multivariate logistic regression analysis, in comparison with patients with hsCRP level ≤3.0 mg/L, those with higher hsCRP levels had more frequently a severe form of PAD (gangrene, P ranged from .045 to <.001; ankle-brachial index ≤.40, P = .059) and had more frequently some of atherosclerotic risk factors (metabolic syndrome, P = .007; hypertension, P = .013; abdominal obesity, P = .007; high levels of uric acid, P = .022; high level of fibrinogen, P < .001; and depression, P = .015).
