Resistance to conventional cardiopulmonary resuscitation in witnessed out-of-hospital cardiac arrest patients with shockable initial cardiac rhythm.
Shockable initial cardiac rhythm is a key predictor of survival after out-of-hospital cardiac arrest (OHCA). However, not all patients with shockable OHCA achieve return of spontaneous circulation (ROSC) via conventional cardiopulmonary resuscitation (CPR). Therefore, we retrospectively analyzed patients with witnessed OHCA and shockable initial cardiac rhythm to identify the resistance factors for conventional CPR. ⋯ The major cause of witnessed OHCA with shockable initial cardiac rhythm was AMI, and resistance to conventional CPR was related to continuous myocardial ischemia.

Comparative StudyComparison of modern risk scores in predicting operative mortality for patients undergoing aortic valve replacement for aortic stenosis.
The aim of our study was to examine and compare the predictive value of operative mortality of the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II, the Society of Thoracic surgeons (STS) score, the Ambler score, and the Japan score in patients undergoing aortic valve replacement (AVR) for aortic stenosis (AS). ⋯ The EuroSCORE II and the Japan score showed superior ability of calibration, but the STS score and the Ambler score overestimated the risk. However, the discrimination power was similar among the four risk scores. In the last quartile of risk, the EuroSCORE II gave an excellent predictive performance.
