ABSTRACT
BACKGROUND AND OBJECTIVES:
The incidence of acute kidney injury (AKI) in hospitalized patients is increasing. Many of these patients survive the immediate post-AKI period and may be prone to developing long-term complications of AKI. This study aimed to determine whether complete recovery following an episode of AKI is associated with a lower risk of long-term major adverse cardiovascular events (MACE).DESIGN:
Retrospective cohort study. SETTING ANDPARTICIPANTS:
Adults admitted to the University of Virginia Medical Center between January 1, 2002 and December 31, 2012 who developed hospital-acquired AKI. PREDICTOR AKI was defined as an increase in serum creatinine (SCr) by ⥠0.3 mg/dL from the baseline and or requirement for acute dialysis during index hospitalization. Complete recovery was defined as a return of SCr to less than 1.25 times the baseline value and not dialysis dependent. Outcome and measurement MACE was defined as subsequent admission for myocardial infarction, stroke or transient ischemic attach and heart failure using ICD- 9-CM codes.RESULTS:
Overall, 11,538 patients survived beyond 90 days of AKI and had data available for analysis. Of the 9,673 survivors of AKI in whom recovery could be assessed, 7170 (74.12%) had complete renal recovery. MACE occurred in 27.28% of our study population over a median follow-up period of 399 days. 28.19% of patients who completely recovered renal function developed MACE, while only 32.48% did in those who did not recover completely. Patients who had complete recovery had a lower risk of long-term MACE when compared with those without complete recovery (adjusted hazard ratio 95% confidence interval (CI) 0.774 (0.713, 0.842)).LIMITATION:
Measurement of albuminuria was not available.CONCLUSION:
Complete renal recovery after an episode of AKI in patients with normal baseline kidney function is associated with a lower risk of long-term MACE when compared with those who did not fully recover.
