Background: The diagnostic accuracy of 64-slice MDCT in comparison with IVUS has been poorly described and is mainly restricted to reports analyzing segments with documented atherosclerotic plaques.
Objectives: We compared 64-slice multidetector computed tomography (MDCT) with gray scale intravascular ultrasound (IVUS) for the evaluation of coronary lumen dimensions in the context of a comprehensive analysis, including segments with absent or mild disease.
Methods: The 64-slice MDCT was performed within 72 h before the IVUS imaging, which was obtained for at least one coronary, regardless of the presence of luminal stenosis at angiography.
Background: The angiography has been used as a reference standard to define coronary artery disease (CAD), although its limitations are well-known. The significance of the myocardial fractional flow reserve (FFR) in the assessment of CAD is well established.
Objective: The aim of this study was to evaluate the accuracy of angiography when defining ischemic lesions and its correlation with FFR.
Objective: To perform a comparative analysis of in-hospital results obtained from AMI patients who underwent rescue or primary PTCA.
Methods: From the Brazilian Interventional National Registry (CENIC), we selected all consecutive patients who underwent a percutaneous coronary intervention for myocardial infarction (< 24 hours), between 1997 and 2000, analyzing those undergoing a rescue (n=840) or a primary (n=8,531) procedure, and comparing their in-hospital results.
Results: Rescue patients were significantly younger males with anterior wall infarctions, associated with left ventricular dysfunction, but had less multivessel disease, compared with those treated with primary intervention.
