NPPB and cerebral infarction: As it is shown in Table 2: after we incorporate the above factors into the multifactor logistic regression model, the NT Pro‐BNP (95% confidence interval [CI]: 11.30 7.65–16.69, p < .001), left atrial diameter (95% CI: 1.22 1.18–1.27, p < .001), cerebral infarction (95% CI: 0.28 0.11–0.74, p < .05), hypertension (95% CI: 5.52 3.78–8.06, p < .001), coronary heart diseases (95% CI: 0.62 0.40–0.97, p < .05) are statistically significant.
