The correlation between hypoalbuminemia and prognosis in elderly patients after endovascular treatment / 中华老年医学杂志

ABSTRACT

Objective:To investigate the incidence of hypoalbuminemia in elderly patients undergoing endovascular treatment(EVT)for large vessel occlusion and to analyze the correlation between hypoalbuminemia and prognosis of EVT.Methods:A total of 640 elderly patients receiving EVT due to acute large vessel occlusion, aged(71.5±7.4)years with 377 males(58.9%), were enrolled into the prospective multicenter cohort study from July 2018 to May 2019.The patients were grouped as the low albumin group(serum albumin levels within 24 h after EVT <35 g/L, n=191, 29.8%)and as the normal albumin group(serum albumin levels≥35 g/L, n=449, 70.2%). The primary outcome was 90-day nerve functional independence defined by the modified Rankin Scale score 0-2.Outcomes were assessed as odds ratio( OR)by using multivariable logistic regression analysis. Results:The proportion of prognosis of good nerve functional independence at 90 d was lower in the low albumin group than in the normal albumin group[22.5%(43 cases) vs.41.9%(188 cases), OR=1.88, 95% CI 1.20~2.95, P=0.01]. The incidence of early neurological deterioration was higher after treatment( OR=0.57, 95% CI 0.37~0.88, P=0.01), and the proportions of multiple systemic complications were higher( P<0.01)in the low albumin group than in the normal albumin group. Conclusions:Hypoalbuminemia after EVT is correlated with the poor prognosis at 90 d in elderly patients.Elderly patients with hypoalbuminemia after EVT have higher incidences of multiple systemic complications.
