Noninvasive cardiac computed tomographic imaging using multislice or electron beam technology has been shown to be highly specific and sensitive in diagnosing coronary heart disease. It is about a fifth of the cost of coronary angiography and is particularly well suited for evaluating patients with a low or low to moderate probability of having obstructive coronary atherosclerosis. In addition,...
Coronary computed tomographic angiography can detect nonobstructive atherosclerotic lesions that would not otherwise have been detected with functional cardiac imaging. Currently, limited data exist regarding the clinical significance of these lesions in patients with acute chest pain. The aim of our study was to examine the prognostic significance of these nonobstructive findings in a patient ...
BACKGROUND Coronary collateral flow is an alternative source of myocardial perfusion in patients with totally occluded coronary arteries. Clinical evaluation of collateral flow has been limited by the need of invasive measurements. We investigated whether noninvasive coronary computed tomographic angiography can evaluate the angiographic extent of coronary collateral flow. METHODS AND RESULTS...
