It is important to note that in the multivariate analysis, lower basal SBP also portended worse prognosis [HR = 1.11 (95% CI: 1.03–1.20) per 10 mmHg decrease in SBP at the index visit], as well as older age, diabetes, atrial fibrillation, lower hemoglobin, and higher BNP. Here, NPPB is linked to atrial fibrillation.
