- Abstract
<bold>Background: </bold>To study different value of estimated glomerular filtration rate with normal serum creatinine whether is a risk factor for hidden renal function of cardiac surgery outcomes.<bold>Methods: </bold>A total of 1744 cardiac surgery patients with serum creatinine ≤1.2 mg/dL (female)/1.5 mg/dL (male) were divided into 3 groups: estimated glomerular filtration rate ≥ 90 mL/min/1.73 m2 (no renal dysfunction, n = 829), 60 ≤ estimated glomerular filtration rate < 90 mL/min/1.73 m2 (hidden renal dysfunction, n = 857), estimated glomerular filtration rate < 60 mL/min/1.73 m2 (known renal dysfunction, n = 58) and followed up for 3 years. Multivariate regression analyses for risk factors of postoperative acute kidney injury.<bold>Results: </bold>The proportion of preoperative hidden renal dysfunction was 67.1% among patients ≥ 65 years old and 44.1% among patients < 65 years old. Multivariate Cox regression analyses showed that for patients < 65 years, known renal dysfunction was a risk factor for postoperative acute kidney injury (P < 0.01) and progressive chronic kidney disease (P = 0.018), while hidden renal dysfunction was a risk factor for progressive chronic kidney disease (P = 0.024). For patients ≥ 65 years, only known renal dysfunction was a risk factors for 3-year mortality (P = 0.022) and progressive chronic kidney disease (P < 0.01).<bold>Conclusion: </bold>Hidden renal dysfunction was common in patients with normal serum creatinine for cardiac surgery, with a prevalence of 49.1%. For patients < 65 years old, hidden renal dysfunction was an independent risk factor for progressive chronic kidney disease.
