Angiographic plaque complexity: the tip of the unstable plaque iceberg.
Coronary plaque rupture is implicated in the pathogenesis of the acute coronary syndromes (1–9). Complex lesion morphology is the angiographic hallmark of these unstable ischemic syndromes, and it correlates with pathologic evidence of plaque rupture (7–9). In this issue of the Journal, Kerensky et al. (10) describe the angiographic patterns of plaque instability in 350 patients with nontransmu...
متن کاملAngiographic and ultrasonic evidence of plaque rupture causing myocardial infarction.
A 60-year-old man with no prior cardiac history presented to the emergency room with 1.5 hours of substernal chest pain. An ECG revealed ST-segment elevation in leads V2 to V6. Acute anterolateral myocardial infarction was diagnosed, and thrombolytic therapy in the form of tPA was administered, with resolution of the chest pain and ST-segment elevation. Because of postinfarct angina, he underwe...
متن کاملCoronary spasm preferentially occurs at branch points: an angiographic comparison with atherosclerotic plaque.
BACKGROUND Coronary spasm plays an important role in the pathogenesis of ischemic heart disease. However, similarities and differences between coronary spasm and atherosclerosis are not known. We examined the angiographic characteristics of coronary spasm in comparison with those of atherosclerosis. METHODS AND RESULTS Thirty-two left anterior descending arteries, 11 left circumflex arteries,...
متن کاملMorphologic and angiographic features of coronary plaque rupture detected by intravascular ultrasound.
OBJECTIVES This study was designed to report the clinical and angiographic correlates of plaque rupture detected by intravascular ultrasound (IVUS). BACKGROUND Acute coronary syndromes result from spontaneous plaque rupture and thrombosis. METHODS We report 300 plaque ruptures in 257 arteries in 254 patients. Plaque ruptures were detected during pre-intervention IVUS. Standard clinical, ang...
متن کاملCarotid intima-media thickness and plaque occurrence in predicting stable angiographic coronary artery disease
BACKGROUND Carotid intima-media thickness (CIMT) and plaque formation have been used as surrogate end-points for evaluating the regression and/or progression of atherosclerotic cardiovascular disease, but their predictive value for stable coronary artery disease (CAD) is inconclusive. METHODS Carotid ultrasonography was performed in patients who underwent noninvasive multislice computed tomog...
