Today, radiological procedures using intravascular iodinated contrast media are being widely used for the diagnoses and treatment of various diseases, which highlight one of the main etiologies of contrast-induced nephropathy and hospital-acquired renal failure. Contrast-induced nephropathy development is associated with longer hospital stay, increase in both short- and long-term morbidity and mortality, in addition to greater health care costs.The pathogenesis of contrast-induced nephropathy has not yet been fully explained in detail; however it is clear that the root concept is medullary hypoxia-induced renal tubular damage.Chronic kidney disease and diabetes mellitus are the two most important intrinsic predisposing factors to contrast-induced nephropathy. As no treatment can specifically target contrast-induced nephropathy, the main goal for clinicians is prevention of the disease. While the best approach for achieving this goal is still controversial, optimization of the patients’ circulating volume remains the only proven strategy to date. As contrast-induced nephropathy is a potentially preventable clinical condition, its better understanding will lead to better prevention of this disease. Hereby, we aimed to discuss contrast-induced nephropathy from 7 different aspects in clinical practice: 1) clinical aspect, 2) prevalence, 3) pathophysiology, 4) contrast agents and renal cell apoptosis, 5) different contrast media, 6) prevention, and 7) treatment.

Adipose tissue surrounding the heart may contribute in the progression of coronary atherosclerosis due to its proximity to the coronary arteries. In addition, epicardial adipose tissue has paracrine and endocrine functions. It can secrete numerous bioactive molecules. Most previous studies examined the relation between coronary artery disease and epicardial adipose tissue have used echocardiography and have reported controversial results, probably due to differences in measurement techniques and study populations. This study aimed to give a brief review on the value of echocardiographic assessment of epicardial adipose tissue in the prediction of coronary artery disease severity.Epicardial adipose tissue, easily and non-invasively evaluated by transthoracic echocardiography, can be considered as an adjunctive marker to classical risk factors despite all the limitations. Moreover, it might be recommended as a useful quantitative screening examination for the prediction of the presence and the severity of coronary artery disease and the extent of atherosclerosis.
