Prevalence of CKD and hypertension by age group (<2 versus ≥2 yr old at surgery), from 3 mo to 4 yr after cardiac surgery discharge (n/total %)
| Outcomes | 3 Mo | 12 Mo | 24 Mo | 36 Mo | 48 Mo | |||||
|---|---|---|---|---|---|---|---|---|---|---|
| <2 yr | ≥2 yr | <2 yr | ≥2 yr | <2 yr | ≥2 yr | <2 yr | ≥2 yr | <2 yr | ≥2 yr | |

| Systolic and/or diastolic hypertension | 21/53 (40) | 12/56 (21)a | 24/47 (51) | 8/55 (15)b | 17/53 (32) | 11/53 (21) | 13/48 (27) | 8/52 (15) | 16/50 (32) | 7/53 (13)a |
| Hypertension and/or CKD | 28/50 (56) | 23/55 (42) | 27/49 (55) | 23/55 (42) | 26/50 (52) | 19/50 (38) | 19/45 (42) | 16/49 (33) | 20/46 (43) | 14/51 (27) |
CKD defined as low GFR, estimated using serum creatinine or high UACR. UACR, urinary albumin-creatinine ratio.
a
P<0.05.
b
P<0.005, for difference in proportion with outcome between AKI and non-AKI groups.
