Impact of abdominal aortic calcification on 90‐day mortality in sepsis patients: a pilot retrospective cohort study

Abstract

We aimed to investigate the association between aortic calcification and 90-day mortality in sepsis patients admitted to the intensive care unit. Methods:We evaluated adult patients (≥18 years) diagnosed with sepsis based on the Sepsis-3 criteria and admitted to our intensive care unit between April 2011 and March 2015. They were classified according to the degree of abdominal aortic calcification (severe and non-severe), grouped per age (<65, 65-75, and >75 years), and matched. Survival curves were generated, and betweengroup differences were evaluated.Results: Overall, 164 patients were included. The Acute Physiology and Chronic Health Evaluation II and Sequential Organ Failure Assessment scores were not significantly different between the severity groups, whereas there were significant differences in age (P < 0.001), sex (P = 0.017), and presence of diabetes mellitus (P < 0.001), hypertension (P < 0.001), dyslipidemia (P = 0.048), and maintenance dialysis (P = 0.001). The severe abdominal aortic calcification group showed significantly poorer prognosis than the nonsevere group (log-rank P = 0.009). The adjusted odds ratio of severe calcification was the highest in patients aged <65 years (7.167; 95% confidence interval, 1.042-49.28, P = 0.045). Twenty-eight patients from each group were matched. The 90-day survival rate of the severe calcification group remained significantly lower than that of the non-severe calcification group (53.6% [15/28] versus 82.1% [23/28], P = 0.022). Conclusions:Severe abdominal aortic calcification is associated with the 90-day mortality of sepsis patients, particularly among those aged <65 years. Thus, caution is necessary in patients younger than 65 years; they may need to be treated with as much care as the elderly.

Investigation of the effects of abdominal aortic calcification on mortality in spinal surgery

“…An investigation revealed that severe calcification in the abdominal aorta was correlated with a significant upsurge in the 90day mortality rate among sepsis patients who were hospitalized in the ICU. Additionally, when analyzing subcategories based on age, the study discovered that individuals under 65 years old with severe calcification also experienced a notable rise in 90-day mortality 22 .…”
