In the same study BNP was related with CE stroke subtype (p<0.001) and resulted an independent predictor of functional outcome ((OR, 0.5; 95% CI, 0.3-0.9) and mortality (OR, 3.05; 95% CI, 1.1-8.2) exclusively in patients with CE [31]. This evidence concerns the gene NPPB and cholesteryl ester measurement.
