Fig. 4.
Multivariable association between standardized lowest blood pressure components for a cumulative 5 min and each of myocardial and kidney injury. Each blood pressure component was standardized (subtract mean, divide by SD) to have normal distribution with mean = 0 and SD = 1. Therefore, 0 on the x axis corresponds to the mean of each variable (i.e., the mean across patients of the lowest blood pressure for a cumulative 5 min). Values of −1 and −2 correspond to blood pressure values 1 and 2 SD below the mean, respectively. The observed mean ± SD was 89 ± 13 for systolic blood pressure (SBP), 61 ± 9 for mean arterial pressure (MAP), 45 ± 8 for diastolic blood pressure (DBP), and 36 ± 12 mmHg for pulse pressure (PP). For all relationships, estimated probability of outcome decreases steadily and then flattens as lowest patient blood pressure increases. AKI, acute kidney injury; MINS, myocardial injury after noncardiac surgery.
