Sudden cardiac death is a serious problem in public health but the overall survival rate of out-of-hospital cardiac arrests (OHCAs) remains low. In this study, we identified clinical parameters to predict the prognosis of OHCA patients and proposed a simple prognostication score for prediction of their prognoses. The study population consisted of 750 consecutive patients with OHCAs of internal cause who were transported to our institute from July 2008 to June 2010. ⋯ When the prognostication score was calculated from these independent predictive factors, a score of ≥ 6 points indicated survival with a sensitivity of 88.6% and a specificity of 97.6%. When the patients were divided into younger and older populations with a threshold of 70 years, these values were 94.1% and 96.1% in younger but 70.0% and 98.4% in older patients, respectively. In retrospective observation, a simple prognostication score was useful to predict patient prognoses in OHCAs, but its usefulness was limited in an older population.

Case Reports
Eosinophilic myocarditis due to Churg-Strauss syndrome with markedly elevated eosinophil cationic protein.
A 67-year-old woman with asthma visited our hospital with increasing dyspnea and new-onset paresthesia and purpura in her legs. Physical examination showed a wheeze, pretibial edema, and surrounding purpura. Chest X-rays showed cardiac decompensation and an electrocardiogram revealed a new ST-T change. ⋯ We experienced a rare case of eosinophilic myocarditis due to Churg-Strauss syndrome. Markedly elevated ECP played an important role in the early diagnosis and subsequent reduction in ECP served as a marker of monitoring. In an asthmatic patient with dyspnea, hypereosinophilia, and vasculitis, Churg-Strauss syndrome with eosinophilic myocarditis should be considered.

There is no reliable method of screening for pregnant women at high risk of developing severe myocardial disorders. In this study, we used vector-projected 187 channel electrocardiography (DREAM-ECG) and serum biochemical markers to evaluate peripartum myocardial burden in pregnant women. Forty-one pregnant women were examined at 36-37 weeks gestation (GW36), 7 days postpartum (PPD7), and 1 month postpartum (PPM1). ⋯ Troponin T was in the normal range during the whole period (< 0.003 ng/mL). In conclusion, these results indicate that the peripartum myocardial burden in pregnant women does not return to normal nonpregnant levels by PPM1. We propose that both repolarization indexes such as RTc dispersion by DREAM-ECG and serum biochemical markers may identify pregnant women at high risk of developing severe myocardial damage in the peripartum period.
