Abstrakt: Aim: We investigated the differences in determinant factors for functional outcomes between patients aged >80 years and those aged <80 years after acute ischemic stroke (AIS). In particular, we would like to know the differential impacts of initial total cholesterol (TC) levels between the two groups.
Methods: We defined a poor outcome as 3-6 modified Rankin Scale 90 days after AIS.
Results: In the present study, 2772 participants were enrolled. Among them, 374 patients (13.5%) were aged >80 years, and 1061 patients had a poor outcome 90 days after AIS. The proportion was significantly higher in patients aged >80 years than in those aged <80 years after AIS. Regarding factors relating to poor outcomes, previous history of stroke, stroke severity and stroke subtypes of ischemic stroke were independent factors in patients aged <80 years, and the stroke severity and initial TC level independently influenced the outcome for patients aged >80 years. In particular, risk of poor outcome adjusted for age, stroke severity and subtypes of ischemic stroke for patients (OR [95% CI]) in the first quartile range (≤157 mg%) were 2.21 (1.06-4.62), in the third quartile range (184-210 mg%) 2.76 (1.27-6.01) and in the fourth quartile range (≥211 mg%) 2.75 (1.21-6.24) compared with those in the second quartile range (158-183 mg%) in patients aged >80 years.
Conclusions: There were also some differences in related factors regarding occurrences of poor outcome between the two groups. In particular, the initial TC level might play a crucial role for the outcome after AIS in the very old population.
