This observational study aimed to characterize patients with both conditions and determine the impact of comorbid PAD\/MVD on outcomes.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Methods and Results<\/jats:title>\n            <jats:p xml:lang=\"en\">Patients admitted across 31 states January 2011 through December 2018 with a primary or secondary diagnosis of PAD or MVD were included from the National Readmissions Database and weighted to approximate a national sample. Those age &lt;18\u2009years or with nonatherosclerotic leg injuries were excluded. Patients were divided into 3 groups: PAD\u2010only, MVD\u2010only, or comorbid PAD\/MVD. Multiple logistic regression was used to evaluate associations with major and minor amputations, major adverse cardiac events, and in\u2010hospital mortality. Cox regression was used to evaluate associations with readmission within 1 year. The PAD group was used as reference. The final cohort included 33\u2009972\u2009772 admissions: 9.1\u2009million with PAD, 21.3\u2009million with MVD, and 3.6\u2009million with both. Annual admissions for PAD\/MVD increased to &gt;500\u2009000 in 2018. Major and minor amputations increased \u224850% for PAD\/MVD between 2011 and 2018. Compared with PAD\u2010only, PAD\/MVD was associated with a higher risk for major amputation (odds ratio [OR], 1.30 [95% CI, 1.28\u20131.32]), minor amputation (OR, 2.15 [95% CI, 2.12\u20132.18]), major adverse cardiac events (OR, 1.04 [95% CI, 1.03\u20131.04]), in\u2010hospital mortality (OR, 1.07 [95% CI, 1.05\u20131.09]), and readmission (hazard ratio, 1.02 [95% CI, 1.02\u20131.02]) after adjustment for baseline factors.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p xml:lang=\"en\">Comorbid MVD is present in a large and growing number of patients with PAD and is associated with augmented risk for adverse outcomes.
