Coronary artery disease (CAD) is the leading cause of death in adults, accounting for more than 480,000 deaths in the US and 1.95 million deaths in Europe each year. There is considerable interest in early diagnosis of CAD, because obstructive coronary artery disease can exist with minimal or no symptoms and can progress rapidly. In patients with symptoms suggestive of CAD, a variety of tests and…

The introduction of tissue Doppler imaging (TDI) strain was a great achievement in echocardiography and for the first time allowed true quantification of regional myocardial function. The central problem with this technique was the angle dependence and the unfavourable signal-to-noise ratio, which has been partially overcome with 2D speckle tracking. Figures 1 and 2 demonstrate application of…

More than 170 million people suffer from diabetes mellitus worldwide and their number is growing continuously. About 65% of diabetics die of cardiovascular disease and diabetes accounts for over a quarter of percutaneous coronary interventions (PCIs).
Diabetes mellitus has been consistently shown to be an important predictor of poor outcomes after PCI. Diabetic patients have an increased risk…

Since the introduction in the early 1980s of magnetic resonance imaging (MRI) in clinical practice, contrast agents (CAs) have been part of MR studies enhancing the capabilities of this diagnostic technique. CAs enhance the contrast between different types of tissues. Tissue contrast depends largely on proton concentration and longitudinal (T1) and transversal (T2) relaxation times inherent to…

Coronary flow velocity reserve (CFVR) represents the ratio between maximal (stimulated) coronary blood flow, induced by using a coronary vasodilator, and baseline (resting) blood flow (see Figure 1). As a ratio it is a dimensionless variable. It could be measured with different tools – some of them, such as intracoronary Doppler flow wire and coronary sinus thermodilution, are invasive methods…

Athletes may occasionally succumb to sudden cardiac arrest because of a quiescent cardiac abnormality. These catastrophes are rare, affecting between 1 in 17,000 to 1 in 50,000 athletes, depending on the sporting discipline.1,2 Most deaths affect male athletes participating in explosive sports of a start–stop nature, such as basketball and soccer, and occur during or immediately after exercise.1…

Worldwide, it is estimated that the total number of people with diabetes will increase from 171 million in 2000 to 366 million in 2030.1 In the US, a total of 23.6 million people have diabetes, representing 7.8% of the population, and the prevalence of diabetes is on the rise, due to an increasingly sedentary lifestyle, increasing obesity and an ageing population. These statistics do not account…
