Baseline Characteristics:
A total of 28,819 patients met our inclusion criteria and were included
in our study. Among them 11,946 (41.5%) were women and 16,873 (58.6%)
were men. The mean age of overall population was 76.1 ± 8.5 years, with
women slightly older than men (women:76.6 ± 8.2 yrs vs. men:75.8 ± 8.7
years; p<0.001). Most patients were covered by Medicare,
followed by private payer coverage. Women had a higher prevalence of
anemia (p<0.001), chronic lung disease (p<0.001),
history of stroke (p=0.005), obesity (p=0.005), and valvular heart
disease (p=0.033). Whereas men had a high proportion of Diabetes
(p<0.001), coronary artery disease (p<0.001),
peripheral arterial disease (p<0.001), and its related
complications. (Table 1).
