The adjusted hazard ratio was similar in the low (1.10, 1.08 to 1.12) and high (1.09, 1.06 to 1.12) ABI subsets. We defined PAD as a low (≤0.9) or high (14.5%) had a 66% greater risk of mortality compared to the lowest quartile (14.5%) had a 66% greater risk of mortality compared to the lowest quartile (<12.8%, p <0.0001) a 1% increment in RDW was associated with a 10% greater risk of all-cause mortality (hazard ratio 1.10, 95% confidence interval 1.08 to 1.12, p <0.0001). We studied 13,039 consecutive outpatients (69.5 ± 12.0 years of age, 60.9% men, 97.6% white) with PAD identified by noninvasive lower-extremity arterial testing at the Mayo Clinic from January 1997 through December 2007, with follow-up through September 2009. Whether RDW is predictive of mortality in patients with peripheral artery disease (PAD) is unknown. N2 - Increased red blood cell distribution width (RDW), a marker of anisocytosis, has been associated with adverse outcomes in multiple settings. This work was supported by Grants HL-81331 and UL1-RR024150 (Center for Translational Science Activities) from the National Institutes of Health, Bethesda, Maryland.
