Inverse correlation between left ventricular end-diastolic pressure and contrast-induced nephropathy in patients undergoing percutaneous coronary intervention

Background There is a rising incidence of contrast-induced nephropathy (CIN), which is defined as either a 25% relative increase or an absolute increase of 0.5 mg/dL (44.2 µmol/L) in the serum creatinine (Scr) level at 48–72 h after administration of iodinated contrast media (CM). We investigated the relationship between left ventricular end-diastolic pressure (LVEDP) and CIN in patients undergoing percutaneous coronary intervention (PCI).
