Superficial Calcified Plates Associated to Plaque Erosions in Acute Coronary Syndromes

This study investigates the clinical relevance and therapeutic implications of OCT identification intracoronary superficial calcified plates (SCPs) in acute coronary syndromes (ACSs). In 70 consecutive ACS patients (pts), we studied three main underlying mechanisms: plaque erosion (PE), rupture eruptive nodule (CN). The PE lesions, occurring on an intact fibrous cap overlying a heterogeneous substrate, were identified 12/70 pts (17.1%). (PE-SCP) represented 58.3% lesions (7/12 pts) had 10% overall incidence culprit (7/70 pts). PE-SCP occurred mostly left anterior descending artery, correlated with white thrombi (85.7%) proximal intraplaque site (71.4%). treated conservatively, as nonsignificant 4/7 pts. Our emphasizes that calcium-related risk is not only associated spotty calcifications or CN but also lesions.
