Risk stratification of patients with unstable angina or non-ST-segment elevation myocardial infarction (UA/NSTEMI) is problematic given the heterogeneous presentation of the condition. This study was undertaken to compare, in UA/NSTEMI patients, the prognostic value of two clinical risk scores (RS) (i.e. Thrombolysis in Myocardial Infarction (TIMI) and physician's risk assessment (PRA)) and to assess whether serum biomarkers can increase the prognostic accuracy of these RS. ⋯ Our study suggests both that TIMI RS is a better marker of risk than PRA RS and inflammatory biomarkers do not increase the predictive value of these clinical risk scores.

Letter Case Reports
Subarachnoid haemorrhage associated with midventricular Tako-Tsubo syndrome.
A new form of Tako-Tsubo cardiomyopathy has recently been described as a midventricular localisation, opposite to the apical typical form. ⋯ This case relates for the first time, the association of a subarachnoid haemorrhage and the recently described midventricular form of Tako-Tsubo syndrome with a hawk's beak. It is an illustration of the complexity of the relationships between brain and heart.

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.
