Comparative Study
Impact of plaque morphology on creatine kinase-MB elevation in patients with elective stent implantation.
The association between percutaneous coronary intervention (PCI) and subsequent myonecrosis has been widely recognized, and worse prognosis has been reported among patients with elevated post-PCI biomarkers. We used optical coherence tomography (OCT) to study the relationship between pre-PCI plaque morphology and post-PCI creatine kinase-MB (CK-MB) elevation. ⋯ TCFA and angiographically complex lesion morphology can predict post-PCI CK-MB elevation in patients treated with elective stent implantation. OCT may be useful in stratifying the risk for nonemergency stent implantation.

Comparative Study
Relation of inflammation and left atrial remodeling in atrial fibrillation occurring in early phase of acute myocardial infarction.
Inflammation is frequently associated with the development of atrial fibrillation (AF). This study was performed to investigate whether the high sensitivity C-reactive protein (hsCRP) present during acute inflammation could predict early AF and its relationship to left atrial (LA) enlargement in acute myocardial infarction (AMI). ⋯ Our results suggest that multivessel involvement, enlarged LA, higher hsCRP, and old age are predictors of early AF after AMI. However, hsCRP could be strongly related to early AF only in AMI patients with less dilated LA.

Kounis syndrome is the concurrence of acute coronary syndromes with allergic conditions like anaphylaxis or anaphylactoid reactions. Cases of hypersensitivity to drugs-eluting-stent (DES) components able to cause serious clinical sequelae, like stent thrombosis have been reported recently. ⋯ To our knowledge this is the first description of intra-stent thrombosis associated with Kounis syndrome. The clinical implications and physiopathology of this association are discussed.
