A significant amount of data has accumulated over the past 20 years, demonstrating the value of exercise or pharmacologic stress non-invasive cardiovascular imaging techniques for the diagnostic and prognostic assessment of patients with suspected or known cardiovascular disease.1-8 Stress can be induced by either multistage exercise testing that is symptom-limited or by pharmacologic means with…

Idiopathic pulmonary arterial hypertension (formerly referred to as primary pulmonary hypertension) is an uncommon yet progressively fatal disease defined by the presence of mean pulmonary artery pressure greater than 25mmHg at rest or greater than 30mmHg with exercise as tested by right heart catheterization in the absence of other etiologies for pulmonary hypertension. Across several studied…

Although less common than other forms of cardiomyopathy, cardiac sarcoidosis (CS), both as part of a systemic process and in its isolated form, is an important, and increasingly recognized disorder. This is felt to be due, in part, to advances in cardiac imaging and heightened awareness of the disorder.1,2 CS is associated with high rates of morbidity and mortality, including sudden cardiac death…

The rapid development of percutaneous coronary and peripheral vascular interventional technologies, as well as non-invasive computed tomography (CT)-based imaging systems, has led to a dramatic increase in the number of patients receiving intravenous or intra-arterial contrast media (CM). It has been estimated that more than 80 million doses (8 million litres) of contrast material are…

Tissue Doppler-based measurements of myocardial strain are possible and accurate for structures that move along the ultrasound beam, but are underestimated in other directions and even impossible for angles close to 90º. To overcome these limitations, the speckle tracking technique was introduced in 2004, offering a more user-friendly workflow and better reproducibility.1 This echocardiographic…

Contrast-induced nephropathy (CIN) in the actual essence of the term refers to renal damage induced by a contrast medium. The ultimate clinical manifestation of CIN is renal failure requiring dialysis, and this article will concentrate on CIN as a clinical outcome. However, transient rises in serum creatinine have been frequently used as a surrogate marker that is suggested to predict renal…

The Problem of Contrast-induced Nephropathy
Contrast-induced nephropathy (CIN) is an increasingly common cause of acute renal failure in both hospitalized patients and out-patients. The growth in contrast-enhanced imaging and interventional procedures is one cause of the increased incidence of CIN. An aging patient population, with more comorbidities such as reduced renal function, may be…

The US has the highest maternal mortality rate in the developed world, at an estimated 26.4 deaths per 100,000 live births. This rate is rising, although it is falling in other wealthy nations.1 Cardiovascular disease is a leading cause of maternal death, so cardiologists need to build on their knowledge and enhance their proficiency on the management of cardiovascular disease during pregnancy.2

Contrast-induced nephropathy (CIN) represents an increasing healthcare burden and challenge as the frequency of diagnostic imaging and interventional studies increase, particularly among populations at risk of developing CIN. As the population ages, decreased renal function and increased atherosclerotic cardiovascular disease become more prevalent. Increasing levels of obesity with resultant…
