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.

Letter Case Reports
A case of Takotsubo cardiomyopathy in a patient with iatrogenic thyrotoxicosis.
Takotsubo cardiomyopathy is a condition caused by intense emotional or physical stress leading to rapid and severe reversible cardiac dysfunction. The etiology and mechanism of this disease are unknown. ⋯ There were some reports of Takotsubo cardiomyopathy with hyperthyroidism, especially Grave's disease. We report a patient who presented chest pain and cardiac arrest, and finally diagnosed as Takotsubo cardiomyopathy caused by iatrogenic thyrotoxicosis.
