Abstract
Background: Contrast-associated acute kidney injury is a severe complication and is a cause of acquired renal failure. Contrastassociated acute kidney injury results in prolonged hospital length of stay and end-stage kidney disease. It also increases mortality and treatment expense. Percutaneous coronary intervention (PCI), nowadays, brings many beneficial treatment consequences. However, the contrast-associated acute kidney injury needs to have more attention in clinical practice. So we implement the study to assess clinical and paraclinical findings and the prevalence of contrast associated acute kidney injury after percutaeous coronary angiograms and interventions. Objects: 221 patients who were diagnosed with coronary disease and treated by PCI. Methods: Prospective observational study. Results: Patients who have NYHA ≥ III comprise 35,3%. The prevalent risk factors of coronary diseases is hyperlipidemia (88,7%), hypertension (43%), smoking (51,1%), overweight (28,5%). The average 24-hour urine volume is 1840,4 ± 376,8 mL. Most patients have kidney function before the procedure decrease to a mild or moderate level (30 - < 90 mL/phút/1,73 m2). No patient has the pre-procedure kidney function decrease to less than 15 mL/phút/1,73 m2. The prevalence of contrast-associated acute kidney injury during PCI is 6,8%. Conclusion: a majority of patients have pre procedure kidney function decrease at a mild to moderate level. Contrast-associated acute kidney injury in patients treated with PCI comprises 6,8%.
