BACKGROUND: Contrast-induced acute kidney injury (CI-AKI) is a recognised complication during primary PCI that affects short and long term prognosis. The aim of this study was to assess the impact of point-of-care (POC) pre-PPCI creatinine and eGFR testing in STEMI patients. METHODS: 160 STEMI patients (STATCREAT group) with pre-procedure POC testing of Cr and eGFR were compared with 294 consecutive retrospective STEMI patients (control group). Patients were further divided into subjects with or without pre-existing CKD...

Contrast exposure in a population with chronic kidney disease (CKD) requires additional consideration given the risk of contrast-induced nephropathy (CIN) after exposure to iodinated contrast as well as systemic injury with exposure to gadolinium-based contrast agents (GBCA). Strategies to avoid CIN, and manage patients after exposure, including extracorporeal removal of contrast media, may differ among an advanced CKD population as compared to a general population. There is strong evidence to support the use of isotonic volume expansion and the lowest dose of low-osmolar or iso-osmolar contrast media possible to decrease CIN...

Gadolinium-based contrast agents (GBCA) are used worldwide for enhanced MRI examinations, including heart and vessels. Gadolinium is a highly toxic heavy metal. If used in GBCA it must be tightly bound to ligands. The configuration of ligands influences the stability of the GBCA and two types of chelates have been used. Macrocyclic chelates offer better protection and binding of gadolinium ion than linear chelates with a flexible open chain - gadolinium could be more easily released from the latter ones. GBCAs are excreted from the body mostly by the kidneys, which is of importance in chronic kidney disease...

Contrast media administration can lead to acute deterioration in renal function particularly in patients with pre-existing chronic kidney disease. This prospective, randomized controlled open-label parallel group study was undertaken at Nizam's Institute of Medical Sciences, Hyderabad, from June to December 2015. A total of 95 patients were included, of which 35 received n-acetylcysteine (NAC) + normal saline (NS), 30 patients received allopurinol (ALL) + NS, and 30 patients received placebo. In our study, the overall incidence of CIN was 24%...

Contrast-induced nephropathy (CIN) is the third leading cause of hospital-acquired acute kidney injury (AKI). Emerging evidence has revealed that soluble klotho (sklotho) could be a novel biomarker for early AKI diagnosis. The aims of this study were to assess the predictive role of sklotho for CIN and to develop a prediction nomogram in patients undergoing percutaneous coronary intervention (PCI). This study is registered on Clinicaltrials.gov (NCT 02650336).Patients aged 18 years or older undergoing planned PCI were prospectively recruited between May 2014 and July 2015...

Contrast-induced acute kidney injury (CIAKI) occurs in up to 30% of patients who receive iodinated contrast media and is generally considered to be the third most common cause of hospital-acquired AKI. Accurate assessment of the incidence of CIAKI is obscured, however, by the use of various definitions for diagnosis, the different populations studied and the prophylactic measures put in place. A deeper understanding of the mechanisms that underlie CIAKI is required to enable reliable risk assessment for individual patients, as their medical histories will determine the specific pathways by which contrast media administration might lead to kidney damage...

BACKGROUND: Despite the use of low-osmolar contrast media that have significantly reduced the occurrence of severe adverse reactions, contrast-induced (CI) acute kidney injury (AKI) remains the third cause of AKI in hospitals. We sought to estimate the frequency of CI-AKI among hospitalized patients undergoing image-guided cardiovascular procedures, to quantify the effect of risk factors on the development of this complication and to assess relative organizational and economic burden in healthcare...

OBJECTIVE: Remote ischemic preconditioning (RIPC) induces transient episodes of ischemia by the occlusion of blood flow in non-target tissue, before a subsequent ischemia-reperfusion injury. When RIPC is applied before percutaneous coronary intervention (PCI), the kidneys may be protected against ischemia-reperfusion injury and subsequently contrast-induced acute kidney injury (CI-AKI). The aim of this study was to evaluate the efficacy of RIPC for the prevention of CI-AKI in patients with diabetes with pre-existing chronic kidney disease (CKD) undergoing elective PCI...

Estimates of the incidence of radiocontrast-associated nephropathy vary widely and suffer from misclassification of the cause of AKI and confounding. Using the Nationwide Inpatient Sample, we created multiple estimates of the risk of radiocontrast-associated nephropathy among adult patients hospitalized in the United States in 2009. First, we stratified patients according to the presence or absence of 12 relatively common diagnoses associated with AKI and evaluated the rate of AKI between strata. Next, we created a logistic regression model, controlling for comorbidity and acuity of illness, to estimate the risk of AKI associated with radiocontrast administration within each stratum...

Contrast media are considered to cause acute kidney injury by activating various factors that induce renal vasoconstriction. We analysed the renal microvascular haemodynamic response using the Doppler flow wire method. Then changes in urinary liver-type fatty acid-binding protein levels following contrast medium administration were compared between groups with or without a micro-injury of the kidney. In the group without renal micro-injury, the average peak velocity (APV) decreased significantly, whereas the renal artery resistance index (RI) increased significantly following contrast medium administration...
