Despite overall improvement, there is still a gender-related disparity in the outcomes of lower extremities peripheral arterial disease (PAD). We analyzed sex-related variability among factors that are known to influence outcomes.

Data on PAD inpatient hospitalizations from New York, New Jersey, and Florida state hospital discharge databases (1998-2007) were analyzed using univariate and multivariate logistic regression analyses.

Of the 372,692 surgical hospitalizations identified, 162,730 (43.66%) involved women. Men and women undergoing vascular procedures differed in that more men smoked (18% vs 14%; P < .0001), and more men had coronary artery disease (40% vs 33%; P < .0001). Women were more likely to be obese (11.86% vs 4.89%; P <.0001), black (18.81% vs 12.66%; P < .0001), older, and have critical limb ischemia (CLI) (39.41% vs 37.67%; P < .0001 …
