In our study, 500 patients who applied to the cardiology clinic and underwent PCI for elective procedure, ST segment elevation myocardial infarction (STEMI), and non-STEMI were prospectively included. Before the procedure, we calculated WBV using the formula [(0.12 × hematocrit) + (0.17 × (total protein - 2.07)]. We defined CIN as the absolute (≥0.5 mg/dl) or relative increase (≥25%) in serum creatinine 48-72 h after exposure to a contrast agent compared with baseline serum creatinine values.
In our study, we aimed to investigate how whole blood viscosity (WBV) affects the development of contrast-induced nephropathy (CIN) in patients undergoing percutaneous coronary intervention (PCI).
