Abstract:
Objective: To analyze the risk factors of acute kidney injury (AKI) after isolated heart valve prosthesis implantation (HVPI) in relevant patients. Methods: We retrospectively studied 400 patients who received isolated HVPI in our hospital. The demographic characteristics and pre-, intra-, post-operative information were collected to conduct uni- and multi-variantanalysis. Results: The pre-operative serum creatinine level in 400 patients was 85.0 (72.0, 98.0) μmol/L and post-operative level was 104.5 (80.0, 146.3) μmol/L, the elevation was 20.9% (1.6%, 57.9%),P<0.05. Multi Logistic regression analysis indicated that age>50years (OR=2.12, 95% CI 1.13-3.95),hypertension history (OR=4.07, 95% CI1.23-13.47), cardiopulmonary bypass time>180 minutes (OR=5.38, 95% CI 1.63-17.77), post-operative hemoglobin<70 g/L (OR=0.20, 95% CI 0.06=0.74), serum glutamic-pyruvic transaminase>100 u/L (OR=12.10, 95% CI 2.28-64.23), pleural fluid drainage at the day of operation> 500 ml (OR=2.12, 95% CI 1.13-3.95), extubation after 24 hours of operation (OR=3.94, 95% CI 2.07-7.52), combining low cardiac output syndrome (OR=4.64, 95% CI 1.06-20.29) were the independent risk factors for AKI occurrence in patients after HVPI, allP<0.05. Conclusion: Post-HVPI AKI was associated with many factors. At prior operation, it was mainly related to the age and hypertension; during theoperation, it was mainly related to cardiopulmonary bypass time; at post-operation, it was mainly related to delayed extubation, low cardiac outputsyndrome, anemia, increased pleural lfuid drainage and serum glutamic-pyruvic transaminase.
