Multicenter Study Observational Study
Bedside tool for predicting the risk of postoperative atrial fibrillation after cardiac surgery: the POAF score.
Atrial fibrillation (AF) remains the most common complication after cardiac surgery. The present study aim was to derive an effective bedside tool to predict postoperative AF and its related complications. ⋯ The POAF score is a simple, accurate bedside tool to predict postoperative AF and its related or accompanying complications.

Multicenter Study Comparative Study
Sensitivity, specificity, and sex differences in symptoms reported on the 13-item acute coronary syndrome checklist.
Clinical symptoms are part of the risk stratification approaches used in the emergency department (ED) to evaluate patients with suspected acute coronary syndromes (ACS). The objective of this study was to determine the sensitivity, specificity, and predictive value of 13 symptoms for a discharge diagnosis of ACS in women and men. ⋯ There were more similarities than differences in symptom predictors of ACS for women and men.

Observational Study
Outcomes of out-of-hospital cardiac arrest by public location in the public-access defibrillation era.
The strategy to place public-access automated external defibrillators (AEDs) has not yet been established in real settings. ⋯ This large, population-based OHCA registry demonstrated that earlier shock, irrespective the shock provider (bystander or EMS personnel), contributed to improving outcome, and a public-access defibrillation program was successfully implemented so that shocks with public-access AEDs were delivered to over 40% of bystander-witnessed OHCAs and time to shock was shortened in some kinds of public places.

Randomized Controlled Trial
Effect of ischemic postconditioning on infarct size in patients with ST-elevation myocardial infarction treated by primary PCI results of the POSTEMI (POstconditioning in ST-Elevation Myocardial Infarction) randomized trial.
Reduction of infarct size by ischemic postconditioning (IPost) has been reported in smaller proof-of-concept clinical studies, but has not been confirmed in other smaller studies. The principle needs to be evaluated in larger groups of ST-elevation myocardial infarction (STEMI) patients before being implemented in clinical practice. This study assessed the effect of ischemic postcoditioning (IPost) on infarct size in patients with STEMI treated by primary percutaneous coronary intervention (PCI). ⋯ http://www.clinicaltrials.gov Unique identifier: NCT.No.PO1506.

Multicenter Study
Thrombolysis delivery by a regional telestroke network--experience from the U.K. National Health Service.
The majority of established telestroke services are based on "hub-and-spoke" models for providing acute clinical assessment and thrombolysis. We report results from the first year of the successful implementation of a locally based telemedicine network, without the need of 1 or more hub hospitals, across a largely rural landscape. ⋯ We demonstrate the safety and effectiveness of a horizontal networking approach for stroke telemedicine, which may be applicable to areas where traditional "hub-and-spoke" models may not be geographically feasible.
