To explore the role of oxygen free radicals produced by the xanthine oxidase pathway on infarct size and left ventricular function, the effect of oxypurinol, an active metabolite of allopurinol and a potent noncompetitive inhibitor of xanthine oxidase, was assessed in a 90 min, closed-chest, canine preparation of occlusion-reperfusion. Animals were(More)
To determine the relation between right ventricular hypertrophy and right ventricular myocardial infarction in patients with chronic lung disease, the records of 28 patients with chronic lung disease, inferior myocardial infarction and significant coronary artery disease (group I) and 20 patients with right ventricular hypertrophy, chronic lung disease(More)
BACKGROUND Mortality and restenosis may be increased in patients with mild to moderate renal insufficiency (RI) after coronary stent implantation. Whether drug-eluting stents safely reduce restenosis and enhance event-free survival in these patients is unknown. We sought to evaluate the impact of baseline RI on clinical and angiographic outcomes in patients(More)
Reperfusion may limit the amount of potentially salvageable myocardium through the introduction of cellular elements into previously ischemic but viable myocardium (reperfusion injury). It has been demonstrated that intracoronary infusion of a 20% intravascular perfluorochemical emulsion (Fluosol) significantly reduces infarct size and results in improved(More)
The purpose of this study was to evaluate prospectively the efficacy and safety of mobile cardiac catheterization. Mobile cardiac catheterization was introduced into clinical practice in 1989, but there has been no systematic study of its performance and safety. A registry was established in 1989 to monitor outcomes with mobile cardiac catheterization and(More)
The administration of a drug soon after reperfusion that could enhance myocardial salvage would have important clinical application. The aim of this study was to assess the long-term effect of the perfluorochemical, Fluosol DA 20%, on infarct size, infarct morphology, ventricular ectopic activity and serial regional ventricular function in a 2 week closed(More)
CONTEXT Despite 2 decades of evidence demonstrating benefits from prompt coronary reperfusion, registries continue to show that many patients with ST-segment elevation myocardial infarction (STEMI) are treated too slowly or not at all. OBJECTIVE To establish a statewide system for reperfusion, as exists for trauma care, to overcome systematic barriers. (More)
OBJECTIVES The aim of this study was to evaluate the rate of timely reperfusion for ST-elevation myocardial infarction (STEMI) with primary percutaneous coronary intervention (PPCI) in regional STEMI Receiving Center (SRC) networks. BACKGROUND The American College of Cardiology Door-to-Balloon (D2B) Alliance target is a >75% rate of D2B <or=90 min.(More)
