Compared with the non-AF institution, sufferers in the AF group were older and had higher plasma NT-proBNP degree, larger CTP quantity (such as CTP ischemic quantity, CTP infarct core extent, and CTP ischemic penumbra volume (P = 0.002)), higher NIHSS score on admission, and lower rLMC score (P < 0.001 for the remaining parameters). Here, NPPB is linked to atrial fibrillation.
