Studies by many scholars have shown that the serum NT-proBNP standard in sufferers with cardiogenic cerebral embolism is loftier than that in other types of stroke sufferers, and when the serum NT-proBNP standard is >360 pg/mL, its correlation with cardiogenic cerebral embolism is the most obvious [15, 16]. This evidence concerns the gene NPPB and intracranial embolism.
