Objectives:
Stroke has become a national concern in China. Early prediction of stroke benefits patients and aids medical professionals in clinical decision making and rehabilitation plans to improve successful outcomes. To identify prediction factors influencing short-term outcomes in patients with acute ischemic stroke (AIS).
Materials And Methods:
This was a hospital-based prospective observational study. Recovery of neurological improvement was represented by a percent reduction in the National Institutes of Health Stroke Scale (NIHSS) at discharge. We performed propensity score matching (PSM) to balance the NIHSS at admission and compared NIHSS scores before and after matching with PSM criteria. Finally, we assessed the prognosis of neurological improvement and patient-related variables.
Results:
In the matched cohort, 92 pairs were matched by NIHSS admission after PSM. Modified Barthel Index, modified Rankin scale, NIHSS on admission, hypertension, sleep time, and Montreal Cognitive Assessment (MoCA) were statistically different between the two groups (P<0.05) before matching. Multivariable analysis identified two factors independently associated with neurological improvement: diabetes (P=0.030; adjusted odds ratio, 2.129; 95% confidence interval [CI] 1.078-4.026) and MoCA (P<0.001; adjusted odds ratio, 5.385; 95% CI 2.278-12.730).
Conclusion:
Consistent with previous studies, diabetes affected the short-term outcomes of AIS, while cognitive impairment had a negative effect on long-term AIS prognosis.Diabetes and early cognitive impairment have adverse effects on short-term prognosis after AIS.
