Abstract

Peripheral arterial disease (PAD) is a prevalent medical condition associated with high mortality and morbidity rates. Despite the high clinical burden, sex-based differences among PAD patients are not well defined yet, in contrast to other atherosclerotic diseases. This study aimed to describe sex-based differences in clinical characteristics and outcomes among hospitalized patients affected by PAD. This was a retrospective study evaluating all patients with a diagnosis of PAD admitted to the Emergency Department from 1 December 2013 to 31 December 2021. The primary endpoint of the study was the difference between male and female PAD patients in cumulative occurrence of Major Adverse Cardiovascular Events (MACEs) and Major Adverse Limb Events. A total of 1640 patients were enrolled. Among them, 1103 (67.3%) were males while females were significantly older (median age of 75 years vs. 71 years; p =< 0.001). Females underwent more angioplasty treatments for revascularization than men (29.8% vs. 25.6%; p = 0.04); males were treated with more amputations (19.9% vs. 15.3%; p = 0.012). A trend toward more MALEs and MACEs reported in the male group did not reach statistical significance (OR 1.27 [0.99-1.64]; p = 0.059) (OR 0.75 [0.50-1.11]; p = 0.153). However, despite lower extremity PAD severity seeming similar between the two sexes, among these patients males had a higher probability of undergoing lower limb amputations, of cardiovascular death and of myocardial infarction. Among hospitalized patients affected by PAD, even if there was not a sex-based significant difference in the incidence of MALEs and MACEs, adverse clinical outcomes were more common in males.
