•Early dynamic change in serum creatinine level <24 hours after primary PCI is a frequent complication of patients with STEMI.•Diabetes mellitus, LVEF, and hemoglobin level were independent predictors of early AKI.•Quick increases in serum creatinine level can sensitively predict 1-year clinical outcomes.•Early AKI was an independent predictor of 1-year clinical outcome.•A graded relation exists between the severity of early AKI and 1-year clinical outcome.
The pattern and prognostic impact of “early” acute kidney injury (AKI) after primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction have not been well established. From November 2005 to November 2011, 971 post–myocardial infarction patients who underwent primary PCI were analyzed. Early AKI was defined using absolute change in serum creatinine (SCr; SCr <24 hours after primary PCI minus admission SCr) as follows: no early AKI (SCr change <0.3 mg/dl), mild early AKI (SCr change 0.3 to <0.5 mg/dl), moderate early AKI (SCr change 0.5 to <1.0 mg/dl), and severe early AKI (SCr change ≥1.0 mg/dl). One-year major adverse cardiac events were defined as death, nonfatal myocardial infarction, and revascularizations. Overall, 9.6% had early AKI, including 5.7% with mild, 2.5% with moderate, and 1.4% with severe early AKI. Diabetes mellitus (odds ratio 1.84, p = 0.042), the left ventricular ejection fraction (odds ratio 0.97, p = 0.042), and hemoglobin levels (odds ratio 0.84, p = 0.039) were independently associated with early AKI. Early AKI (adjusted hazard ratio 2.80, p = 0.005) was an independent predictor of 1-year major adverse cardiac events. The adjusted hazard ratios of 1-year major adverse cardiac events from the lowest (reference) to the highest quartile of early AKI were as follows: 1, 2.87 (p = 0.012), 3.22 (p = 0.021), and 5.83 (p = 0.004), respectively. In conclusion, early dynamic change in renal function after primary PCI can sensitively predict worse outcomes.
