    2. In vivo correlation between morphological characteristics of coronary plaques and functional characteristics of carotid arteries in acute coronary syndrome

      In vivo correlation between morphological characteristics of coronary plaques and functional characteristics of carotid arteries in acute coronary syndrome
      Background: Carotid artery temperature heterogeneity () measured by microwave radiometry (MWR) has been associated with future cardiovascular events including acute coronary syndromes. The vulnerable plaques of the coronary arterial tree, that can be ideally depicted by intracoronary imaging such as optical coherence tomography (OCT) have anatomical characteristics such as the thin fibrous cap (TCFA), that make them vulnerable to rupture. The scope of the study was to assess the implication of ...
