[Acute and long-term clinical results of bare metal coronary stenting].

Background: Since the introduction of stents in 1994, improved clinical results have boosted the development of coronary angioplasty in Chile. Drug eluting stents, that have a reduced rate of restenosis, are being increasingly used.

Aim: To assess the acute and long-term results of bare metal stent implantation.

Human factors impact successful lay person automated external defibrillator use during simulated cardiac arrest.

Objective: With the dissemination of automated external defibrillators in the community, there is increasing lay person use, along with less formal automated external defibrillator training and retraining. Therefore, the "ease of use" factors related to the human-device interface may be vital for successful use. We sought to determine whether human factor differences would result in differences in parameters of successful or safe use by lay persons in the setting of simulated cardiac arrest.
