In the analysis of the CES group, age (OR 1.036; 95% CI 1.004–1.069), LV systolic dysfunction (OR 4.400; 95% CI 2.009–9.638), NT-proBNP (OR 12.614; 95% CI 3.713–42.853), creatinine (OR 1.464; 95% CI 1.116–1.920), and NIHSS score (OR 1.131; 95% CI 1.082–1.182) were associated with mortality in the univariate model. Here, NPPB is linked to cat-eye syndrome.
