Objectives: To investigate the impact of on-site cardiac interventional facilities on the management and outcome of patients with versus those without ST elevation acute coronary syndromes (ACS) in the Canadian-American Global Use of Strategies to Open Occluded Coronary Arteries (GUSTO) IIb population.
Methods: Data from 4605 patients were analyzed in relation to the admitting hospital's capability to perform coronary procedures (noninvasive, angiography-capable and interventional hospitals). Differences in medication use, revascularization rate and patient outcome were determined.

Free radicals have been implicated in the etiology of cardiac dysfunction during sepsis, but the actual species responsible remains unclear. We studied the alterations in myocardial nitric oxide (NO), superoxide, and peroxynitrite generation along with cardiac mechanical function and efficiency in hearts from lipopolysaccharide (LPS)-treated rats. Six hours after LPS (4 mg/kg ip) or saline (control) treatment, hearts were isolated and perfused for 1 h with recirculating Krebs-Henseleit buffer and paced at 300 beats/min.
