Coronary angioplasty of multiple vessels: short-term outcome and long-term results.

abstract：BACKGROUND:It is recommended that comatose survivors of out-of-hospital cardiac arrest should be cooled to 32° to 34°C for 12 to 24 hours. However, the optimal level of cooling is unknown. The aim of this pilot study was to obtain initial data on the effect of different levels of hypothermia. We hypothesized that deepe...
