[Importance of severe lesions left untreated in patients with acute coronary syndromes and angioplasty of the culprit lesion].
INTRODUCTION AND OBJECTIVES Patients with acute coronary syndromes may have significantly stenotic nonculprit lesions that do not show complex lesion morphology. We investigated whether these lesions were prone to become unstable since they exist within a prothrombotic and inflammatory systemic milieu. PATIENTS AND METHOD We evaluated the clinical course of 150 patients after successful angio...
متن کاملDo plaques rapidly progress prior to myocardial infarction? The interplay between plaque vulnerability and progression.
There is a common misperception in the cardiology community that most acute coronary events arise from ruptures of mildly stenotic plaques. This notion has emanated from multiple studies that had measured the degree of angiographic luminal narrowing in culprit plaques months to years before myocardial infarction. However, angiographic studies within 3 months before myocardial infarction, immedi...
متن کاملIdentification of culprit lesions after transient ischemic attack by combined 18F fluorodeoxyglucose positron-emission tomography and high-resolution magnetic resonance imaging.
BACKGROUND AND PURPOSE Carotid endarterectomy is currently guided by angiographic appearance on the assumption that the most stenotic lesion visible at angiography is likely to be the lesion from which future embolic events will arise. However, risk of plaque rupture, the most common cause of atherosclerosis-related thromboembolism, is dictated by the composition of the plaque, in particular th...

متن کاملAssessing culprit lesions and active complex lesions in patients with early acute myocardial infarction by multidetector computed tomography.
BACKGROUND Accurate, non-invasive characterization of culprit lesions in patients after acute myocardial infarction (AMI) remains challenging. In this prospective study, multidetector row computed tomography (MDCT) is used to assess culprit and active complex lesions in patients early after AMI. METHODS AND RESULTS We enrolled 103 patients with first non ST-elevation AMI who underwent 64-slic...
