for determining the extent of hibernating myocardium ( 2 ). The stressor used for SE can be physical exercise, pacemaker stress, pharmacological agent or a combination of pharmacological agents ( 3 ). Dobutamine is the preferred pharmacological

Dobutamine stress echocardiography (DSE) has been utilized extensively in the detection of coronary artery disease (CAD) and prediction of patient outcome ( 1 , 2 , 3 , 4 ). Its safety has also been thoroughly investigated in the contemporary

Introduction Dobutamine stress echocardiography (DSE) is commonly performed during follow-up after cardiac transplantation as part of surveillance for the diagnosis of cardiac allograft vasculopathy (CAV). Previous studies have demonstrated the

Introduction The expanding responsibilities and skillset of the Highly Specialised Cardiac Echocardiography Physiologist include performance and analysis of exercise and dobutamine stress echocardiography studies ( 1 , 2 ). Physiologist

cardiac physiologist’. He reminds us ‘that the biggest danger associated with dobutamine stress echocardiography is in misinterpreting the data obtained…’. Did Ntoskas et al . ( 2 ) really misinterpret the data? Dr Porter states that 7 patients with

Fig. 16. Figure 16 Summary of recommendations for DSE in low-gradient AS with impaired LVEF. After exclusion of technical error, such patients should be considered for dobutamine stress echocardiography (DSE). Conventional

either through physiological means with exercise or pharmacological means such as the beta-adrenergic effects of dobutamine. Dipyridamole is predominantly vasodilatory causing increased coronary flow through inhibition of cellular re-uptake of adenosine

( 1 ). As 2-dimensional echocardiography became more widely available, a wealth of data accrued during the 1980s and 1990s demonstrating the feasibility, safety and accuracy of exercise ( 2 ), dobutamine ( 3 ) and dipyridamole ( 4 ) stress
