NPPB and ischemic stroke: There were statistically significant differences in age, prior ischemic stroke, STW time, HR at admission, ST-segment elevation leads (STELs) and their number, high-density lipoprotein (HDL) cholesterol levels, peak CK, N-terminal pro brain natriuretic peptide (NT-proBNP), proportion of LAD artery opening or proximal occlusion, occlusion site of LAD artery, prescription rates of Glycoprotein IIb/IIIa receptor antagonists and beta-blocker, and global registry of acute coronary events risk (GRACE) score between the two groups (P < 0.05).
