In this examination, the serum NT-proBNP standard in the cerebral infarction set was notoriously loftier than that in the contrast set, and the loftier the NIHSS score, the loftier the serum HCY standard in the stroke sufferers; the extensive the infarct size, the loftier the serum HCY standard in the stroke sufferers, indicating that NT-proBNP standard can be used as a predictor of the occurrence and progression of stroke sufferers [19, 20]. This evidence concerns the gene NPPB and brain infarction.
