NCT01370265
Blockage of the heart arteries (coronary artery disease) can lead to angina (chest pain), heart attacks, heart failure, and/or death. Positron emission tomography (PET) stress myocardial perfusion imaging (MPI) is a powerful tool to help identify blockages in the coronary arteries. During the PET MPI test, a drug is given to mimic the effects of exercise on the heart. The study was done to measure blood flow to the heart using two similar drugs approved to mimic the effects of exercise on the heart in people during a heart stress test. The first drug, called adenosine, has been approved for this use for several decades. The second drug, called regadenoson, was approved in 2008. The investigators were looking at whether the increase in blood flow to the heart with the newer drug (regadenoson) was similar to the increase in blood flow with the older drug (adenosine). This information is important for the use of these drugs in patients and for interpreting the blood flow values.
NCT01064765
This study is designed to determine if a relationship exists between problems with memory, attention, learning, insight and executive function and self management in heart failure.
NCT01932671
After having had a first cardiovascular event, there is a considerable risk of developing a subsequent event. Only recently, a risk prediction model was developed for this group of patients. Imaging techniques such as the coronary artery calcium score and contrast-enhanced computed tomography (CT) of the coronary and carotid arteries could be able to add improve this model. Imaging may further improve the prediction of future manifestations of arterial disease and personalize disease monitoring and treatment.
