Abstract
Lower extremity peripheral artery disease (LE-PAD) has been linked to unfavorable cardiovascular outcomes. The impact of potentially undiagnosed LE-PAD, suspected by abnormal ankle-brachial index (ABI), on the survival of sepsis patients admitted to the intensive care unit (ICU) remains uncertain. We conducted a prospective cohort study and recruited adult patients admitted to the ICU with a primary diagnosis of sepsis (defined by a quick Sepsis-Related Organ Failure Assessment score of ≥ 2) between November 23, 2017 and July 22, 2018. ABI measurements were obtained within 24 hours of admission. The study compared the 30-day and 1-year all-cause mortality rates as well as the incidence of major adverse cardiovascular events (MACEs) between the groups with normal and abnormal ABI values. Of the 102 sepsis patients admitted to the ICU, 38 (37%) were diagnosed with LE-PAD based on their ABI measurements. The overall 30-day mortality rate was 30.0% in patients with LE-PAD and 25.8% in those with normal ABI (p = 0.56). At 1 year, the overall mortality rate was 52.6% in the patients with abnormal ABI and 40.6% in those with normal ABI (p = 0.24). Additionally, the incidence of MACEs was significantly higher in the patients with abnormal ABI compared to those with normal ABI at 1-year follow-up (21.1% vs. 3.1%, respectively; p = 0.003). The patients with abnormal ABI had a higher incidence of MACEs within one year following hospital discharge. Future studies are needed to improve cardiovascular outcomes among sepsis survivors (ClinicalTrials.gov number, NCT03372330).
