Left ventricular end diastolic pressure and contrast-induced acute kidney injury in patients with acute coronary syndrome undergoing percutaneous coronary intervention.

•Intravenous administration of contrast material is responsible for more than 10% of cases of hospital-acquired acute kidney injury (AKI) and has been associated with high rates of morbidity, mortality, resource utilization and prolonged hospitalization.•We assessed whether there was a correlation between left ventricular end diastolic pressure (LVEDP) and the risk of developing contrast-induced AKI in 254 acute coronary syndrome patients undergoing urgent or emergent coronary angiography.•Nearly one-in-seven patients developed contrast-induced AKI.•There was a numerically higher rate of contrast-induced AKI in those patients with normal or elevated LVEDP when compared with patients with low LVEDP, however it did not reach statistical significance.•Baseline LVEDP was not associated with the development of contrast-induced AKI.•Patients that developed contrast-induced AKI were noted to have significantly lower left ventricular ejection fraction compared to patients that did not have contrast induced AKI.
